View Full Version : VDPAU- Should I try it?

I have read about the new VDPAU support, and am wondering if I should try it. http://zacgarrett.com/software/installing-mplayer-vdpau/index.html gives a fairly involved way to do this. http://www.avenard.org/files/mythtv-vdpau/ says I can simply install a new repository, then upgrade the system. Have other mythbuntu users tried either of these? I am interested in peoples experiences and opinions.

If you have a card supporting VDPAU and you wish to watch 1080p conent, I would say it is a must. I'm building a AMD X2 5600+ (dual core 2.9Ghz) HTPC for a mate with a Asus M3N78-VM motherboard which has the Nvidia 8200 IGP. Watching a high quality 1080p/DTS bluray rip used to consume 90%+ of the CPU and result in servere video stutter and audio sync issues. After installing the 180.22 drivers and compiling the VDPAU enabled Mplayer CPU usage dropped to around 15%, and the related stutter and sync issues disappeared. Some people say that if you have a fast enough CPU then VDPAU doesn't matter, however I haven't found that to always be the case.

If you follow the first guide at the top of this thread, then there is nothing to recover as you run the VDPAU enabled Mplayer in parrallel with the standard version.

As always backup before you do any major changes.

My frontend boots from a small (8Gb) CF card in a CF-SATA adapter. Before I make any major changes I boot up in rescue mode, go to the command prompt and then copy the Boot CF to a backup CF card (Plugged into an USB card reader). The command I use to copy the entire CF is:-

dd if=/dev/sda of=/dev/sdb bs=4k

A backup takes about 15-20minutes, but thats alot less than reinstalling everything if an update goes wrong :D

The flash memory thing sounds complicated. I recall hearing about a way to back up the mythtv database- which would probably be enough.
Also I would be interested hearing which method people used for installing vduap and what problems they ran into.

Finally got a 9400gt from the childrens box :)

I'll be trying it out this evening/tomorrow. Is it really as easy as adding the http://www.avenard.org/files/mythtv-vdpau/ repositries and doing an apt-get update/upgrade?

I'll post my findings here in the next few days.

I'm also curiosu to know the results. I'm lookign at building a mythbuntu box around the gigabyte GA-E7AUM-DS2H.

This makes it sound like all you'd have to do is install the latest nvida driver and add the repositries!

The results have been good, but you'll get more info on the mythtv-user mailing list, or mythtvnz. Archives are at http://www.gossamer-threads.com/lists/mythtv

Hi All,

1) Backedup my dediated backend to another CF card.
2) Booted from it and enabled the http://www.avenard.org/files/ubuntu-repos release/ repo.
3) Did a apt-get update/upgrade
4) Enabled the nvidia driver in the ubuntu "Hardware drivers tool"
5) Rebooted and started watching a recording, saw about 20% CPU load
6) Went into the mythfrontend playback profiles screen and changed all profiles to use vdpau.
7) Rebooted and watched the same recording again and saw about 5-6% CPU load.

Note: Both recordings watched are SD. I'll try HD sometime today.

The only problem I'm having is some tearing in the video, I think I know what the solution is.

The upgrade isn't just an apt update/upgrade and everythings OK. Unless your willing to spend sometime debugging/setting up vdpau I'd recommend waiting for an official release.

Oh and do a full backup of the system before you start playing. It took me three attempts before I got a working/stable system.

EDIT: Just tried HD (BBC HD/Torchwood) and the CPU load is 5-10%. Without vdpau it was about 80-95%. VDPAU makes a huge difference for me.

I posted a quick FAQ answering most of the questions asked here:
http://www.avenard.org/files/mythtv-vdpau/

Q: Video is tearing
A: Tearing when composite is enabled is the norm (checkout the driver readme for more details). Add to your xorg.conf:
Section "Extensions"
Option "Composite" "Disable"
EndSection

Q: When I start playing a Video/LiveTV I get a blank screen:
A: To prevent blank screens when running without composite, try running with:
USE_VDPAU_COLORKEY=1 mythfrontend.
Amended Answer: Use patch > 19970, it fixes many bugs related to colorkey

Q: I get stuttering every few seconds with errors like "NVP: Video is 3.12705 frames behind audio (too slow), dropping frame to catch up."
A: Check your settings: In General: make sure "Aggressive sound card buffering" is unckecked
In TV -> Playback "Extra audio buffering" is checked.

Q: I installed your latest patch, and it makes my machine crash
A: You must run nvidia drivers >= 180.25 with the latest patches

Now, for the people asking if adding my repository is enough to get VDPAU working, then the answer is yes.
My packages are made from the mythbuntu original packages ; as such they are 100% compatible.

Warning, do not activate the mythbuntu weekly build repository. The weekly repository is updated every week, and due to the nature of SVN ; each week the version number will increase ; even if there has been no changes in Mythtv 0.21-fixes.
If you activate the mythbuntu weekly build, it is likely that at some stage the weekly repository will update mythtv and will remove the VDPAU mods.

To use VDPAU, all you need to do is add to your /etc/apt/sources.list:
deb http://www.avenard.org/files/ubuntu-repos release/
deb-src http://www.avenard.org/files/ubuntu-repos release/

You can also enable the testing repository which is updated more often ..
deb http://www.avenard.org/files/ubuntu-repos testing/
deb-src http://www.avenard.org/files/ubuntu-repos testing/

This repository also includes the Nvidia drivers. One thing to know, the nvidia drivers are also 100% compatible with the nvidia drivers found in 9.04.. However, since 180.11 the structure of the package has changed. The vdpau libraries are now found in a separate package (libvdpau-180).
As such, you can't upgrade easily from 180.11 to 180.22 or later.

You must de-install any previous nvidia drivers (<180.22) then install the new one. If you attempt a simple upgrade, you will get an error about vdpau.

BTW, you will never get an "official" 0.21 release with VDPAU

The upgrade isn't just an apt update/upgrade and everythings OK. Unless your willing to spend sometime debugging/setting up vdpau

I disagree, it is precisely that: it's an update/upgrade and everything is okay.
There are no modification required to the backend or the database. You can always revert back to the official build of mythtv.

And the only setup required is creating a VDPAU video profile in the TV Settings -> Playback

Installing my mythtv packages with VDPAU will not mess your system in any way .. It doesn't touch the structure of the database *ever*.

I can't imagine why it would have taken you 3 attempts to get it working.

If it doesn't work for you; uninstall mythtv, disable my repository. Re-install mythtv.
That is it.

Cheers
Jean-Yves

Hi Jean-Yves,

Your the guy that backported the vdpau code to 0.21.

Firstly I'd like to say thankyou very much for all the work you put in at getting vdpau working in 0.21.

The biggest problem for me to get the NVidia drivers running correctly. My first attempt went wrong as I didn't remove the old NVidia drivers before installing the new ones which left me low resolution mode in X and alot of errors about conflicting versions.

My second attempt should have worked as I deinstalled the old drivers and installed the 180. but they wern't activated in the Hardware Drivers programm (Where you can chose which version of the NVidia drivers to use).

The third attempt worked.

I actually gave up each time quite quickly as I have a "dd" backup of the frontend harddisk which only takes afew minutes to load and I got myself into such a mess that I started again from new rather than trying to sortout the mess.

All I can say now, is thankyou very much. Less than 10% CPU load when playing HD (1080p h264) video is wonderful. I can now use cpufreqd to slowdown the CPU to 1200MHz (Core2Duo) without any side effects.

You don't need to activate the hardware drivers program if you manually install the 180.x drivers ...

it should automatically be recognised.

the only manual change you need to do is modify xorg.conf so it uses the nvidia driver

If I had a VDPAU compatible card it would be great. I installed from the Avenard repo and it works great, even the nvidia driver. This version runs really well for me and it may just be my imagination, but, I've been happier with the playback even without the VDPAU enabled in the playback settings. Enabling it crashes myth, like I said before I don't have a compatible card. Oddly the mobile version of the card is listed in the compatible list. If it doesn't work I'd make a backup of our database (actually, Id do this first), then uninstall myth, and reinstall it from the standard repo. This worked for me when I downgraded from this version temporarily. I'm back to using it again. one thing I can think of is that this repo is for 8.10, 8.4 doesn't have the right version of some things to meet the required dependencies.

The mythtv package contains a lot of fixes ; including OpenGL fixes which can be very useful even if you do not use VDPAU.

If you do set a video profile with VDPAU and your card isn't VDPAU compatible ; it shouldn't crash. It will default to ffmpeg/Xv instead

To use the new opengl mods; set opengl or opengl2 as renderer and try the new hardware accelerated deinterlacer ; I had great result with Yadif HW,2X for SD and Kernel HW,2X / or MotionGreedy for HD.

Yes, this repo is for 8.10...

I did this upgrade and it was relatively painless except for a issue I had with the nVidia drivers not loading properly. Loading nvida-new from apt-get then installing the new nvida drivers again solved the problem. I would recommend only upgrading mythtv and not doing a full upgrade. The new mysql also caused me issues with the new config file being loaded and only accepting local connections.

Very impressed with the results of the VDAPU.

VDPAU won't work well with the stock nvidia drivers that comes with Ubuntu

The new mysql also caused me issues with the new config file being loaded and only accepting local connections.

??? there is no change to the database whatsoever with my package ; and for the backend/database it's just the mythbuntu package compiled ...
So any issues you have there you would have had it with the standard mythbuntu package

Should of been more clear. I had to load (install) the ubuntu nvidia driver then loaded (installed) the new nvidia driver from nvidia site a second time because the first attempt to install the nvidia drivers from the nvidia site failed the first time with API version error messaged in dmesg.

When I did a apt-get upgrade a new MySQL config file was loaded with settings for allow localhost only.

Just wanted to say thanks to JYA for making the patches and repository available. It's working even better than before, many small improvements, and of course, with VDPAU reducing CPU use.

8.10 + mythtv + Nvidia 8400GS.

Same config and graphics card (256MB model for me) and same good result. Excellent work. Much praise to jyavenard.

With vdpau enabled the pauses I used to see when using the program guide while TV was running went away. On the other hand, so did the live TV that used to be visible at the same time the guide was up.

The only glitch I have seen so far concerns PIP, where sometimes it comes up with H = 2W (stretched vertically), instead of H = W. Oddly the stretched one uses much less CPU time than the rectangular one, which tends to push to 50-60% CPU, where regular TV (one stream) is <=10%. Also the front end hung up for a longish time once when trying to switch PIP streams.

VDPAU + mythtv is definitely a big win.

THANKS!

Boy- this thread really has legs! I am still interested in trying VDPAU, but I will need things to be to be a bit more step-by-step before I am confident enough to try it. So here are my questions:

-first, I need a good way to recover if this fails, and am wondering if I can adapt Ian Dobson's system to my hardware by simply backing up my root directory to a usb flash drive. Would something like this work:
dd if=/dev/sda1 of=/dev/sdb bs=4k -to back up. (or of=/dev/sdb1 ?)
dd if=/dev/sdb1 of=/dev/sda1 bs=4k -to restore. (or if=/dev/sdb ?)
(what does the bs=4k do?)
sda1 is my root directory, and sdb would be the flash drive.
I assume I would boot from a rescue disk to restore, but would I have to do this when making the backup, so the drive wouldn't be active?

-next, do I remove nvidia drivers first? Do I just run sudo apt-get remove nvidia-* ? If I do this from X will things work untill I reboot?

-then to install the repository do I (per Jean-Yves Avenard's site) just run:
echo "deb http://www.avenard.org/files/ubuntu-repos release/" | sudo tee /etc/apt/sources.list.d/avenard.list ?

-and then is just running updates enough to install VDPAU? Will I need to re-install nvidia drivers? Is that just apt-get install nvidia-something, or will I be able to run the mythbuntu setup tool?

-once the drivers are installed, is enabling them simply a matter of going into the Mythtv playback settings or profiles and choosing VDPAU as the playback engine?

I am hoping you experts can answerer some of these questions, and perhaps it will act as a guide for us less expert users.

Thanks for the help. Probably I should post the backup question in the general forums. So here's how it would work, as I currently understand it:

-install the repository as per JYA.
-do a system update.
-re-install the nvidia drivers from mythbuntu setup(?)
-choose vdpau in mythtv's setup menu.

Is it really that simple?

Pretty much.

Before you do anything else:

cd ~
. /etc/mythtv/mysql.txt
mysqldump -u$DBUserName -p$DBPassword $DBName -c >mythtv_backup.sql
cp /etc/X11/xorg.conf ./xorg.conf.save

With any luck you will never need to use the mythtv_backup, you will need a safe copy of xorg.conf. One should remain in /etc/X11 but it will end up with a name like "xorg.conf.fglrx-12" and you may not know which was the last good one.

On my system after I added the repository and did:

sudo apt-get update
sudo apt-get upgrade

it did NOT pick up the new nvidia driver. To do that it was necessary to do a manual:

sudo apt-get install nvidia-glx-180
sudo apt-get install nvidia-180-modaliases

After that

mythbuntu control center -> restricted drivers -> select 180 (should now be on the list), quit.

Reboot to single user (root)

sudo cp -f xorg.conf.save /etc/X11/xorg.conf
#test it
startx
# should start up X11 as before the upgrade
# use ctrl-alt-backspace to shutdown X11
exit
(select resume)
#system should come up normally, starting X11 like before the upgrade
#myth should also start up as it did before.

Then all you have to do is in mythfrontend (already running)

Utilities/Setup -> Setup -> TV settings -> playback -> step through to Playback Profiles (3/9). Edit the profiles, change the decoder to "Nvidia VDPAU acceleration", that should also change Video Renderer and OSD Renderer to "vdpau". And voila, much (much) lower CPU usage.

I'm using 8.10 with MythTV installed (not mythbuntu). I followed the instructions to get the patched version running and it seemed to work for the most part. I had some trouble getting the 180 nvidia drivers installed but in the end I think I did get them. The trouble is that I'm not using mythbuntu control center so I'm not sure which nvidia drivers I'm using. I used synaptic to get them, here's the window that shows all the nvidia files I installed:

http://img27.imageshack.us/img27/9089/nvidiar.th.jpg (http://img27.imageshack.us/my.php?image=nvidiar.jpg)

When I look at the Hardware Devices control panel, it no longer has the two nvidia 17x drivers listed, it just has "nvidia" with a green dot and no version numbers.

VPDAU is visible in my playback profiles setup page but when I select it and then try to watch either live tv or any recording I get an error. The preview videos play in the recordings menu, but when I select one to watch, I get one of two errors. I'm assuming this onboard video card is compatible with vdpau, but I'm not sure.

$lspci
...
02:00.0 VGA compatible controller: nVidia Corporation GeForce 8200 (rev a2)

One other issue is that even without vdpau selected I get a black screen unless I use the composite disabled flag in xorg.conf. Then compiz fusion effects don't work. I can live without them, but is there a way I can have both?

So to boil it down, I need some help getting vdpau to work. Any suggestions?

TMcC

February 24th, 2009, 05:05 PM

Way I got it to work was by using Jean-Yves Avenard's patches.

Steps I followed were:

*Download Mythbuntu 8.10
*Install... but DO NOT select the 177 drivers when you go through the Mythbuntu control centre
*After installation, add the repositories shown by: http://www.avenard.org/media/Ubuntu_Repository/Ubuntu_Repository.html
*Do a "sudo apt-get update"
*Do a "sudo apt-get install nvidia-glx-180"
*Reboot, and check that you're using the nvidia driver by running "nvidia-settings".
*Do a "sudo aptitude safe-upgrade"
*Grab mplayer_vdpau.sh from http://www.knoppmythwiki.org/index.php?page=HardwareAcceleratedVideo
*Stick in /usr/local/bin and alter myth to use that script instead of mplayer
*Try using myth to play a 1080p video, checking cpu usage.

Note, you may need to alter the amount of shared memory assigned to your 8200. 128MB isn't enough, 256 might be.

And don't use compiz...

Also check post #14 of this thread.

Thanks, Jean-Yves, for the backports and the repos. Great stuff!

The only major problem I have consistently now is that changing from one channel to another on the same tuner using the live TV guide will produce two errors and crap out to the main menu. "Failed to reinit video", I think.

VDPAU is impressive. I'm able to get 1080i MPEG2 / Temporal 2x to play back perfectly with my lowly integrated 8200. I did have to give it 512MB of RAM to play with in BIOS, since it would error out with just 128. I didn't try 256.

April 14th, 2009, 09:21 AM

you will want to upgrade your nvidia drivers if you want to try VdPAU

current stable version is 180.44

If you are upgrading from 180.11 to 180.44 ; you must uninstall the nvidia drivers first before you can install 180.44

doing a simple upgrade will fail..

Just did, went to the 185 drivers and got update packages for mplayer and made a config in my homedir for mplayer to start trying with the VDPAU-assisted codecs first and ith works pretty much ok. Some overlay problem with after restarting mplayer seems to be over and significantly dropped CPU-hogging. I like it :)
Later on I'll take the plunge to using your repo or waiting for .22 of mythtv, but sofar I'm happy.

Hi

I have just started using jyavenard's vdpau build of Myth and I'm impressed. My CPU usage with 1920x1080 video is now under 10%.

I think however I have found a bug. Basically I want to use the standard software decoding for everything except HD video (as the deinterlacing seems to be much better with software). So I modified the "high quality" playback filter to use vdpau with 1920x1080 video, however this doesn't work and myth always uses the software decoding. Not sure if this is because when I start watching TV Myth (correctly) starts playback with software and does not recheck the playback rules when I change to a HD channel.

Has anyone else experienced this, and have any suggestions?

utar

April 15th, 2009, 09:44 PM

Just for the record, there isn't a bug. It seems that BBC-HD transmits in 1440x1080 and as such I had my playback rule wrong as this was set for 1980x1080.

Let me chime in here with my attempts at this.

Wow, it's amazing. I'm using an ASUS 9300 based board with a Dual Core Pentium e5200, and I went from spikes near 100% to running around 5-7% CPU utilization in MythTV. I'm doing HDMI output to 1080i (older TV), and this works great. Note my video card is allocated 256 megs, if anyone has questions about that. Occasionally I have video hiccups (quick freeze and then all the missed frames get played back at lightning speed), but considering the level this stuff is at in development, it's awesome. I'm on 8.10 64 bit.

In mplayer, 1080p mkv container files would frequently drift out of sync badly, and with the vpdau enabled mplayer and the latest everything (as of May 2nd), it's just amazing. Very very impressed.

Thanks for all your efforts JYA!

Jean-Yves,

HD playback is just great using your repository in Mythbuntu 9.04, thank you very much.

I have only one minor issue.

Before, mplayer disabled the Gnome Screensaver when playing a movie. Now ater installing the mplayer from your repository this is not longer the case. After 10 minutes the screen gets blank.

It does not matter if I replace or keep the mplayer.conf during installation.

Do you (or anybody else) have an idea, what goes wrong?

Thank you!

Regards,

Familienvater

I had this problem and I fixed it by adding a command line option to mplayer. From memory I think it was "-stop-xscreensaver", however I'm not in front of my Myth box at the moment. I'll check later.

Thank you for your quick answer, utar!

But actually this doesn't seem to work for me. I added -stop-xscreensaver to the command line, but this is ignored by mplayer. I also tried to add

stop-xscreensaver = "yes"

to mplayer.conf. This does not disable the Screensaver. What's worse, Mplayer even crashes when playing some videos (I don't know what's so special about these files)

What I do not understand: How is the screensaver disabled in the standard configuration? There is neither an entry in mplayer.conf nor a command line option!

Regards,

Familienvater

from man mplayer:

−heartbeat−cmd

Command that is executed every 30 seconds during playback via system() - i.e. using the shell.

NOTE: MPlayer uses this command without any checking, it is your responsibility to ensure it does not cause security problems (e.g. make sure to use full paths if "." is in your path like on Windows). It also only works when playing video (i.e. not with −novideo but works with −vo null).

This can be "misused" to disable screensavers that do not support the proper X API (also see −stop−xscreensaver). If you think this is too complicated, ask the author of the screensaver program to support the proper X APIs.

EXAMPLE for xscreensaver: mplayer −heartbeat−cmd "xscreensaver−command −deactivate" file

EXAMPLE for GNOME screensaver: mplayer −heartbeat−cmd "gnome−screensaver−command −p" file

I just had a look.

The original mplayer found in ubuntu comes with extra code for handling the gnome screen-saver.

The one I build is straight from the SVN code.

I added the patches found in debian/patches which is the usual location for all patches ; but the original ubuntu package directly patched the source code. So I had missed that.

I will rework on my mplayer package to include the gnome screen saver support.

I never noticed because the screen saver on my box, which is exclusively used for mythtv, is disabled by default

Edit/Update: I re-added the old KDE screensaver support... I'm rebuilding packages, they will be in the release directory as I've tested them to be working as intended...

Hi

Allright, I ported the gnome-screensaver support and updated mplayer to revision #29317

I'm uploading the packages in the testing repository.

Something to note:
the old mplayer 1.0rc2 had native support for the KDE screensaver and the ubuntu package add supports for the gnome screensaver.

The latest version in trunk has support for neither of them... I added support for gnome.

That means there's no support for the kde one.

I will be looking at adding support for the KDE screensaver next.

nickrout

May 20th, 2009, 04:43 PM

I believe the mplayer devs got sick of gnome and kde not using the X API's for disabling screensaver, and ripped out the hacks for gnome and kde. The comments in the man page that I quoted above bear this out. Whether they should be patched back in, or whether you should use the -heartbeat-cmd, or whether you should be hassling the gnome/kde devs to get it right is a moot point I guess.

jyavenard

May 20th, 2009, 09:14 PM

I uploaded the mplayer changes with gnome and KDE screen saver support.

May I please ask for help?

I am running mythbuntu 8.10 and am having trouble upgrading my system. What is the correct process? My understanding of it is:

1. uninstall old nvidia driver (sudo apt-get remove nvidia-glx-new)
2. Add Jean-Yves' repository, then update and upgrade.
3. Install new nvidia driver (sudo apt-get install nvidia-glx-180)
4. Install "modaliases" (sudo apt-get install nvidia-180-modaliases)
5. Reboot and the new driver should be loaded and the upgrade will install the VPDAU patches and VPDAU will be available as an option in Mythtv.

When I follow this process though, upon rebooting I get a message saying that I am loading low-graphics mode, and I can't seem to avoid that message even after reinstalling the nvidia driver.

Can anyone please point out what I am doing wrong?

Thanks,
Luke

Re-run nvidia-xconfig or make sure xorg.conf correctly use the nvidia drivers is all you need to worry about.

No need to run the nvidia installer

I've been using jya's ubuntu 8.10 repository for a while and have been very happy.

However recently something seems to be going funny with the dependencies. Earlier in the week there was an Myth update that wouldn't fully install without me removing nvidia-180-libvdpau and installing nvidia-185-libvdpau. Anyway after some trouble I got 185 install and everything was good.

Anyway today I notice that there is another myth update which now wants to uninstall 185 and install 180. I would prefer to stick with 185 now I have it installed.

Is this just me missing something and can anyone give me any suggestions?

Thanks.

[Edit: just noticed on Jya's website that he has reverted back to 180 so please ignore the above!]

I installed the latest vdpau build today and now seem to have a problem with lcdproc. Basically 2 "screens" are being opended on my lcd and the display switches between the mythtv screen and a blank one every few seconds.

If I kill mythlcdserver then the switching stops.

Is anyone else seeing this, or is it just me?

An update to lcdproc was done in 0.21-fixes SVN #20697
http://svn.mythtv.org/trac/changeset/20697

The VDPAU built doesn't modify anything there, so any issues seen must come from upstream unfortunately

Does anyone else have a problem w/ the most recent stable release breaking their HVR-2250? For some reason my backend is not able to determine the type of tuner and information in the frontend list the tuners as unavailable.

The VDPAU built stay very far from anything touching mythbackend ..

Is your 2250 seen by the system properly ?
You can always try one of the latest mythbuntu weekly built and see if it's any better.

If it works there, but not with my build, I'd be happy to investigate

What do you mean by "crashing" ? an actual crash, or the frontend exits with an error (that's not a crash).

Try to switch to a video playback profile not using VDPAU and see if it plays any better.
if it does, but not with VDPAU I'd like to get a sample of your recording if possible to have a look at it.

Any issues seen in the backport is likely in trunk, so any fixes made here would be for the better good :P

Fix:

Delete all the previous HVR-2250 install folders then download and reinstall the driver. (LowSky's install tutorial worked)

OK, I tried doing this yesterday, and ended up with a horror show on my hands. I am running Mythbuntu 9.04 which currently uses the 180.44 NVidia drivers. THe steps I followed were....

1. Deactivated the NVidia Drivers
2. Added the vdpau repository release and testing
3. Disabled weekly builds
3. update / upgrade...here's where I think my torubles began, because it said it could only do a partial upgrade

After all this, I never did get any updates to the nvidia drivers. I also couldn't re-activate the ubuntu nvidia drivers, kept getting an error about "held broken packages". I downloaded the 185 drivers from NVidia and managed to install them manually, however the playback was horrible (with and without vdpau enabled) and my CPU usage was holding around 90% (with and without vdpau enabled), compared to the normal 55% with the CPU++ profile. Entirley frustrated and dejected :), ended up doing a fresh install of the system...this is just a frontend, so it's relatively painless.

So now, I have a nice clean machine with all updates and the most current weekly build on it and the standard 180.44 drivers from ubuntu, and ready to try again. My plan this time is....

1. Disable weekly builds
2. add vdpau repository release ONLY this time
3. update / upgrade

Now, other than actually creating a vdpau playback profile, is there anything else I need to do? I am not planning on uninstalling or deactivating the NVidia drivers this time...is this required if I am already running the 180.x series of drivers? Will the update / upgrade automatically update the 180.44 drivers to the 180.60 drivers?

Wrong steps.

testing repository uses drivers 185.xx ; which IMHO aren't usable despite being tagged as official stable by nvidia.

only activate [release]

There was no need to de-activate the nvidia drivers if you were running ubuntu 9.04.

Uninstalling the nvidia drivers was only required on 8.04 when you had 180.11 drivers.

3. Disabled weekly builds
3. update / upgrade...here's where I think my torubles began, because it said it could only do a partial upgrade

This last plan is the good one.

Adding a VDPAU playback profile is all you need to do. And let it upgrade to 180.60, reboot or restart X after doing so...

lots of fixes in 180.60.

First off, I would like to thank jyavenard for the ubuntu repositories. It has made this build doable for me. Mostly everything seems to be working great so far in my MythTV frontend. I am still testing.

Zotac IONITX-C-U
1GB RAM
4GB USB flash drive
HDMI with audio
Mythbuntu 8.10

The one problem that I do know of is related to the nvidia-settings dialog. I made my normal adjustments to gamma and saturation from that dialog. These adjustments carry over to the MythTV menus, but playback seems to ignore them. I also have a Zotac GeForce 8200 frontend and playback respects the settings. The systems are similar except that I am not using VDPAU acceleration on the 8200. I am not sure what to do. Any suggestions?

uncle hammy

July 13th, 2009, 07:59 PM

OK, this time it went well! I don't seem to have any ill effects of using vdpau (stuttering with or without the OSD, etc), and my CPU usage has gone froma steady 55% to 3%.

one thing...

With the new builds, the preview screen of the Program Guide doesn't display anything. I happen to use the MePo theme, which displays the channel logos when the guide is viewed when not watching something or the live preview if viewed while watching something. With the new builds, it always displays channel logos only, regardless. I checked other themes, and there simply is no preview window. It appears that calling the guide while in "viewing mode" is loading the same guide that gets displayed in "Manage Recordings".

Other than that, I am very impressed. Nice work!

I am discovering one more thing. There appears to be some instability with LiveTV. I have had several instances where the frontend exits to the desktop when trying to change channels, and one instance where LiveTV locked up completely unresponsive (couldn't even ssh in) requiring a hard shutdown.

Using 185.18.14 drivers by any chance?
it's typically what occurs when using VDPAU on my mythtv frontend.
180.60 has proven to be much more reliable

jyavenard

July 19th, 2009, 10:48 AM

I'm having a bit of trouble with VDPAU. Here's what I've done so far:
1. make sure my card is VDPAU-compatible (onboard 8200)
2. add jyavenard's repos (release only), update & upgrade
3. create a vdpau profile in mythtv
4. disable composite in xorg.conf
If I understand what I've read in this thread correctly, this should be all I need to do to experience the magic of VDPAU. Problem is, it's not working. Playback is jerky, and CPU usage is around 60-90%. Am I missing something?

If your CPU is around 60-90% , you're certainly not using VDPAU

The 8200 is very low end, and it won't allow you to use most of the nice vdpau deinterlacers. Bob 2X seems to be one reported to work almost reliably with a 8200.

In any case, you'll have to provide a log to see what's going on.
Start mythfrontend with:
mythfrontend.real -v playback
and post back the results.

Using 185.18.14 drivers by any chance?
it's typically what occurs when using VDPAU on my mythtv frontend.
180.60 has proven to be much more reliable
No, 180.60 drivers.

you aren't using VDPAU for decoding here but software decoding, and vdpaubasicdoublerate which your 8200 will never handle properly.

edit your video playback profile so it only uses vdpau, never the default decoder...
like create one with one entry only:
> W: 0 H: 0, decoder: VDPAU, renderer: VDPAU, Deinterlacer: Bob 2X

To prevent errors like "Error at util-vdpau.cpp:870 (#23, The system does not have enough resources to complete the requested operation at this time"

try to increase the amount of RAM shared by the GPU.

And finally, make sure you follow my FAQ:
http://www.avenard.org/media/MythTV_%26_VDPAU/MythTV_%26_VDPAU.html

in particular, the audio settings...

All suggestions followed, and it appears to be mostly working - playback looks better, and CPU usage has dropped to ~25%. :D I'm still getting masses of "video ahead of/behind audio" errors, though. Aggressive sound card buffering is unchecked & extra audio buffering is checked, as you instructed.

Despite those errors, does it play okay ?

Disable the AC3 upmixer if you have it enabled and change the upmixer settings to "Passive" this will lower your CPU usage even more, and may help playback

Both of those options were already set that way.

It plays better than before, but you can see it stuttering sometimes when it hits an audio/video sync error. I just checked playback with the default CPU+ playback profile, and I'm getting the same errors, so it's not strictly a VDPAU thing.

I'm currently running 9.04 and am planning to install a new graphics card (Gainward 9400 (http://www.gainward.net/main/vgapro.php?id=128)) to my box and try VDPAU. Couple of questions:

1. As far as I understand, these are the steps I have to perform to get things working
a) enable jyavenard's repos (release only, not test)

If you want to use drivers nvidia drivers 180.60 yes.
To use 190.18 you need the testing repository.
But even those drivers are still a tad unstable and crash on a daily basis (though not as much as 185.xx)

b) update & upgrade
c) create a vdpau playback profile
d) a few other tweaks (as per FAQ) if required

some of the tweaks mentioned in the FAQ aren't even necessary anymore as if using the vdpau profile it will automatically set things up automatically such disabling the aggressive audio profile.

Is this it, anything I've forgotten ?

2. Any backups required ?

You may want to backup your database for the sake of it... though no modification to the database is made.

3. If for whatever reason things go wrong, how can I revert back to the original situation ?

Yes, simply disable my repository. Uninstall all mythtv packages and re-install mythtv.
It's the easiest way and nothing will be lost.

My vdpau packages are based on the mythbuntu packages so many things are in common, in particular it uses the same file location and configuration, so they are compatible with one another.

Could keep mythbuntu packages on your backend for example, and only use mine for the frontend.

Though, my packages do add fixes for h264 recordings so the time is properly recorded...
0.21-fixes is buggy for those, and I backported some fixed from trunk.

Yes. Settings will be fine. All settings are stored on a mysql database which survive everything.

BTW, you're better off getting a nvidia 9500GT video card instead of a 9400. The 9400 isn't fast enough for using the advanced deinterlacers on HD content.

The passively cooled 9500 is a lot bigger than the 9400 and I don't have a lot of room in my case, so I had to go with the 9400.

Okay, installed the card, did the changes, not quite working as it should.

Live TV is showing "random blocks" throughout the picture. Any idea ?

Which driver should be installed ? nvidia control panel is telling me 180.60. Is this the right version ?

Also, on the desktop (or in applications like firefox right now) tiny white specs appear and disappear in black areas (like the letters of this post).

jyavenard

August 15th, 2009, 03:52 AM

Make sure your cable is properly connected and not bent.
I see random white dots when I the cable is too bend on my system.

There's an issue seen with 185.x drivers where random points appear everywhere, but I haven't heard about this issue with 180.60.

For VDPAU, after intalling the drivers, did you reboot? when you start nvidia-settings, does it see the proper driver: it's the only way for testing if you are running the proper driver.

As for random block in playback, this can only occurs if your TV stream is corrupted.

Cable seems okay, same position as before.

As for random blocks during playback: I doubt it's a corrupted stream (I assume you mean some kind of reception issue). This hasn't happened before.

I hate to say it, but these two issues (random blocks and white dots) haven't happened before, starting when putting in the new card and updating.

I did reboot. What do you mean with "does it see the proper driver"? How do I check ?

start nvidia-settings and see which drivers it states you have. did you have an nividia card before? which driver did you use?

there's no way vdpau or mythtv would have anything to do with corrupted display and firefox.. Could be a faulty video card ...

I still would check the cable...

Check if the 180.x drivers support your video card first.
But yes, you can use my packages. They aren't specific to using VDPAU only.
they contain a lot of fixes and extra features not even found in MythTV trunk yet (though many of them are being comitted)

I think I'm narrowing the problem down.

These problems only occur when I use the playback profile I set up for vdpau.
When I revert back to teh standard CPU+ profile everything is fine. So it's not a faulty card or a dodgy cable connection.

Interestingly enough, the white dots on the desktop are also gone when I'm not using the vdpau profile. I suppose that's because I was still running mythfrontend with live tv, just switched to firefox. So the vdpau problems somehow affected the desktop, if that makes sense.

My mythtv settings can even explain why it would cause a corrupt display outside of mythtv.

It's either a driver issue, or a graphic card issue.

Now, I've never heard of such issue with the 180.xx drivers ; some people did report white dots everywhere with 190.xx drivers...

Try rebooting the PC completely, see if it still does it ...

Try using the "testing "repository with the 190.18 drivers...

Done that, doesn't change a thing.

Try using a different video card.

Only other video card I have is the onboard GF7, which doesn't support vdpau. Works fine with your repos though and doesn't show any of the issues I described.

I also just noticed another thing: when starting to watch a video (which calls up mplayer) the volume is ridiculously loud. Previously the volume had to be around 50% in player to be alright, now it's got to be at the lowest possible setting. Live TV and music are still the same as before, so I guess it's something to do with mplayer. Any setting I can change somewhere to rectify this.

Note: mplayer also doesn't seem to keep the volume setting, ie everytime I start to watch a video it starts at full volume.

mplayer has been updated to a much more recent version of mplayer (as of yesterday in fact)

but you don't have to use mplayer to play a video.
Change it to use the internal player.

In the settings, go to edit the file type, and change the various type to use "Internal" (uppercase I is important) instead of the default player.

my 0.21-fixes contains patches that makes it play much more content than the stock 0.21-fixes

If it doesn't:
a) revert back to 180.xx, your release repos and don't run the vdpau profile
b) revert back all the way to the original repos

Both of which make the new graphics card kind of obsolete :(

Not really... Mythtv in my repo add other playback options not available on stock 0.21-fixes. in particular the new opengl accelerated video renderer. A 9400GT is going to be much faster than what you had before when it comes top OpenGL.

Try the new Yadif OpenGL HW accelerated.

But frankly, with a 9400GT, VDPAU is much better.

Another question: does the internal player make use of vdpau at all ?
Of course, even mplayer can you vdpau

If you're using an AMD processor with frequency scaling, when using VDPAU make sure the minimum CPU speed is set at 1.8GHz, not anything slower. When using frequency scaling, AMD (unlike intel processor) also slows down the external databus, below 1.8GHz it's not fast enough to feed the graphic card with the video stream.

6. Mark to install nvidia-glx-185

Where ? Can you explain ?

Thanks.

Those instructions were for 185.xx drivers, latest ones are 190.18, use the same instructions but replace anything with 185 with 190

I have taken from this thread all i need to do is add the followin repos;

To use VDPAU, all you need to do is add to your /etc/apt/sources.list:
deb http://www.avenard.org/files/ubuntu-repos release/
deb-src http://www.avenard.org/files/ubuntu-repos release/

And then sudo apt-get update
sudo apt-get upgrade

Hi laffinet,

Maybe can you try underclocking your card. You can patch/flash the bios using nibitor and nvflash (only under windows).

I had afew problems with my pasive cooled NV9400 until I underclocked it abit. I think the problem was caused by heat and underclocking the card reduced the temperature by a good 20°c.

EDIT: You might be able to adjust the GPU/MEM frequency using nvclock from the repos.

This is done in the frontend setup. In the frontend go to Setup, TV settings, Playback settings. Select next a few times until you get to the "playback profiles" screen.

You need to create a new profile called vdpau, then edit that profile and create a few entries. Going by JY's FAQ (here (http://www.avenard.org/media/MythTV_%26_VDPAU/MythTV_%26_VDPAU.html)) you need to create these entries:
< W: 1920 H: 720, decoder: VDPAU, renderer: VDPAU, Deinterlacer: Advanced 2X

>= W: 0 H: 720, decoder: VDPAU, renderer: VDPAU, Deinterlacer: Temporal 2X

Hope this helps.

Hi JY,

I'm having a few stability issues with the testing repos and the 190.xx driver, so I tried reverting back to "release" and the 180.60 drivers. I must be doing something wrong though, because it's not working as planned.

Here's what happened:
- deleted "testing" from the repos
- opened synaptic, reloaded, selected "mark all upgrade"

This is where I expected a message coming up saying 190 will be uninstalled, 180 will be installed, but that never happened. So I manually selected for 190 to be uninstalled and 180 to be installed

- selected uninstall myth
- applied
- apt-get update again (probably unnecessary)
- apt-get install mythtv

This is where I really ran into trouble, as apt was telling me there are unmet dependencies. From what I can tell it was about installing some 190 components which should really be 180 components.

Because it was getting late and I needed a working myth installation I ended up adding the testing repo again and installing the 190 driver and mythtv and everything worked fine, but I'd really like to go back to the "release" version.
What am I doing wrong ?

Do I need to uninstall mythtv with the "testing" repo still active ?

Not just as simple as adding the repos. I have just restarted and got an error window stating;
Ubuntu is running in low graphics mode;

Failed to load module type1 (module does not exist)
Failed to load module freetype )module does not exist)
EE NVIDIA 0 failed to intialize the nvidia kernel module
please ensure that there is a supported nvidia gpu in this system
and that the nvidia device files have been created properly.

***Aborting***
Screen found but none have a useable configuration!

Some how it seems to have confused my system which drivers to use. I dont think i am running the nvidia drivers anymore and cannot get into the nivida settings from within the menu, however if i go into hardware drivers it shows 180 as active and in use!

How do i recover my system? It was nice and stable with 180.60 installed and active before this update repos was used.

Its now all messed up with various X windows failing and default settings being used by mythbuntu at the desktop. HELP!

I have just downloaded and installed 185.18.31 driver and sadly have the same error. Plus i now have API mismatch errors between 15 and 180. I have tried editing nano /etc/default/linux-restricted-modules-common
to exclude "nv nvidia_new"

but the api mismatch is still there!

Pretty frustrating as i cannot get into my mythbuntu machine now other than terminal (which scores low with WAF!)

EDIT:::::

I am trying to go back to 180.60 as we speak. I am hoping this will get around the api mismatch errors so i can get back to x normally. Still in need of help though.

Right, with 180.60 installed and a fresh build/install of X I am back into my system with the nvidia drivers loaded.

I am noticing a fair few more artifacts watching live tv than i had before enabling vdpau. I am going to look into under clocking my card but without windows this seems like it might be tricky. nvclock doesnt fully recognise my 8300 card so i am not sure i can do anything.

How can i disable vdpau until i can sort these artifacts? (Can i just remove the display profile and go back to cpu++?)

Yes, just choose a different playback profile (without hardware acceleration) and you should be fine again.

I'll be looking into underclocking my card as well and report back.

Somebody also suggested compiling my own driver, will have a look at that too.

Your process looks okay to me..

The way I do it is:
-Remove testing repository
-Reload (that's important)
-Uninstall all mythtv packages
-Apply
-Install mythtv packages, this will prompt to remove libvdpau-190 and use libvdpau-180 instead
-Install nvidia-glx-180 ; this will automatically uninstall nvidia-glx-190 and nvidia-190-kernel-source
-Apply

Either reboot, or do (in a text console):
/etc/init.d/gdm stop
rmmod nvidia
modprobe nvidia
/etc/init.d/gdm start

You can tell which nvidia drivers mythtv is linked against by looking at the version number.
0.21.0+fixes-21349-openglvdpau2-nv180-0ubuntu2

nv180 indicates that it is using nvidia drivers 180.xx

No worries. Underclocking is a bit of a now-go at the moment. nvclock doesn't support my card yet. There seem to be ways to override that and force underclocking regardless, but I'm reluctant to do that.

So unless I find some other suggestions on how to solve this artefacts issue I'm at a dead end...:(

Okay, I managed to revert back to the release version (had to select a lot of the packages separately though, as dependencies weren't met automatically. Not sure if that's normal).

One thing I noticed, though:

mencoder version installed is this one:
1.0-svn29519-nv190-0ubunut0

which says requires >=190.xx for vdpau.
Is this correct ? I can't see another mencoder version in synaptic.
mplayer seems fine (1.0-svn29501-x264-vdpau-0ubunut0)

If you use my repository, it includes extra playback option using OpenGL hardware-accelerated deinterlacer.

With a 9400GT, I had excellent result (2nd best after VDPAU) using the following profile:

W <= 1920 ; H < 720: OpenGL / Kernel (2X, HW) or OpenGL / Greedy Highmotion (2x)

W > 0 ; H >= 720 : OpenGL / Kernel (2X, HW)

Greedy HighMotion 2X requires quite a fair bit a processor, if you have less than a C2D @ 2.66GHz, better of using Kernel 2X,HW

Wow, that isn't working with my machine at all.
Greedy Highmotion produces choppy picture fullstop.

Kernel 2x,Hw works, but the CPU (AMD AM2X2 5000+) is sitting around 150% (doesn't really make sense but I guess top is looking at both cores).
Shouldn't opengl transfer some of the load to the graphics card ? Is there a way to check if opengl is working ? Anything I need to change anywhere else ? xorg.conf ?

mythfrontend sits around 150% when watching TV with your settings. Opengl seems to be the issue. Any deinterlacer combined with opengl is producing this kind of CPU load on my machine.

I've also tried the vdpau renderers (combined with ffmpeg decoding), but didn't have much luck there either.

I'm pretty much back to ffmpeg&xv-blit, which brings my CPU to 80-90%. Not ideal and I guess it doesn't really use my graphics card very well. Almost at the point of taking the card out and going back to the onboard gforce7 and xvmc.
But I'm willing to try other options if there are any.

I just have a terminal window open in the background and run "top" in it. Then switch to the terminal window with ALT+tab while watching TV to see the loads.

Firstly - jyavenard, Thank you so much for the time you have put into this.

I installed a HVR-2250 using Steven Toth's drivers with no problems. Then I installed VDPAU support. I'm appreciative of how easy it was for a relative newb to get this all running.

One question, I have had the 185.18.29 NVIDIA drivers since they came out (EV3A GeForce 8600GT). I skipped the steps to install video drivers since I currently meet the requirement on the Add VDPAU support to MythTV 0.21 (http://www.avenard.org/media/MythTV_%26_VDPAU/MythTV_%26_VDPAU.html) page. I've read through this thread carefully though, and it appears that these may not be the best option? I've not yet experienced and problems and under the theory of don't fix what ain't broke, I was planning to leave things be. Any reason that I should reconsider this approach?

If you are using my repository, you will have to use either 180.60 (release repo, recommended) or 190.25 (testing repo, unstable with vdpau).
I've only had problems with 185.18.29. They work fine as video drivers, but start using vdpau and you will get your computer crashing.

Mind you, there are issues in all those drivers.
In 180.60, the OpenGL library sometimes segfault (especially noticeable in mythmusic with the fancy libvisual based animated screen) ; but on the vdpau side of things it's very stable.

190.25 still has some known issue:
First, you must disable UseEvents : this is a problem on non-vdpau playback like Xv, without UseEvents X will take 100% of the CPU time.
You also need to disable opengl v-sync, otherwise libGL segfault
The other libGL segfault with 180.60 are gone ; but every once in a while , about once a day, two of my computers running 190.25 hang and require a power cycle.

So I still recommend you stay with 180.60, for a 8600GT card , it would make very little difference, if any

Note: mplayer also doesn't seem to keep the volume setting, ie everytime I start to watch a video it starts at full volume.

Just in case somebody is experiencing similar problems, I managed to overcome this issue (mplayer starting at a ridiculously high volume) by adding
-ao alsa
to the video player line in mythfrontend setup.

Hi JY,

I'm currently running your "testing" repos (190.25 driver), with standard decoding and vdpau rendering. Since the latest update came through (this morning I think) I now have this "white dots" issue I mentioned earlier even without vdpau decoding.

However, I've got a bit more information: it's not actually white dots, it's the TV picture "showing through" in black areas.

Have a look at the attached photo. It's a photo of the TV screen while displaying a wikipedia page in firefox with mythtv running in the background. The original photo is here (http://en.wikipedia.org/wiki/Black)
That red and white stuff is the actual TV picture showing through.
Interestingly enough, the black square at the top of that wikipedia article displays fine, plain black, nothing showing through.

Hope this somehow helps finding the problem.

August 30th, 2009, 06:24 AM

The update yesterday was about fixing a possible segfault when some custom modelines were defined with particular characters in the name.

Other than that there's been no difference...

So I believe this is purely a coincidence.

You can try reverting to the previous version if you want...

Do you have Compiz installed and running? try disabling it to see if it makes a difference.

I am slightly confused as to why my vdpau comes up with so many "artifacts" during playback. I am running 180.60nvidia drivers and have setup the playback settings as described here. If i use cpu++ my average cpu loading during live tv playback is around 18%. If i use high quality i get around 48-50%cpu loading. With vdpau selected i get lots of artifacts on all channels (that are no there without vdpau) but reduced cpu loading down to around 6% average.

My GPU (8300) is onboard my motherboard but isnt supported by the underclocking util so Im guessing i am kind of stuck as to getting vdpau working.

Is there any problem with running 50%cpu loading during livetv playback? Using highquality does seem to have solved the audio "clicking" i was getting during live tv in cpu++, but obviously does have a higher cpu loading to boot.

Incase it matters im using 9.04 64bit on an AMD 64 5050e (dual core 2.6GHz) with 2gbram so should be up to the job of a media center combined front/back end.

like very large pixcels appearing on the screen (similar to those displayed during very bad reception), except they are only present with vdpau selected and not with high quality or cpu++. They are worse when the picture is high speed (such as the f1) but present around all moving objects as very large square over sized pixcels.

Same config and graphics card (256MB model for me) and same good result. Excellent work. Much praise to jyavenard.

With vdpau enabled the pauses I used to see when using the program guide while TV was running went away. On the other hand, so did the live TV that used to be visible at the same time the guide was up.

The only glitch I have seen so far concerns PIP, where sometimes it comes up with H = 2W (stretched vertically), instead of H = W. Oddly the stretched one uses much less CPU time than the rectangular one, which tends to push to 50-60% CPU, where regular TV (one stream) is <=10%. Also the front end hung up for a longish time once when trying to switch PIP streams.

VDPAU + mythtv is definitely a big win.

THANKS!
PIP does not really work for me with VDPAU. It technically does show the other tuner in a window, but the window is almost in the middle of the screen and is no larger than a dime. I run at 1920x1080 res. When I change my profile to Slim instead, PIP works great. The window is just under 1/4 the size of the screen and is in the bottom left position where I have it setup to be.

I think I know the answer to this, but will this also impact the live TV window in the Program Guide? It does not seem to work with VDPAU but does with CPU+ or Slim. Based upon all this, do you think it will ever be possible so we don't lose features to get HW acceleration, or is this a technological limitation we just are stuck living with forever?

I'm not sure if the the VDPAU upgrade did this but mythwweather no longer displays any info. See my detailed post here:

http://ubuntuforums.org/showthread.php?t=1260567

I saw in another post on mythweather problems that the author of this VDPAU upgrade conceded that it did cause a problem but I'm not sure about the fix.
Any ideas?
Thanks

Ok, I upgraded mplayer with Jean-Yves repository using apt-get update
apt-get upgradeand then configured myth frontend for play back using VDPAU as per http://www.avenard.org/media/MythTV_%26_VDPAU/MythTV_%26_VDPAU.html It did not work for some reason, the error messages said i needed to recompile it so I did using this (http://blog.avirtualhome.com/2009/05/29/how-to-compile-mplayer-with-vdpau-support-on-ubuntu/) tutorial. I tried it and it gave me a blank scren and I could not exit it or even kill it from top. so I recompiled it again and then it would not even start up at all. so I removed it, reinstalled it from Jean-Yves repository, still can not get it to run. I tried it from a terminal and recieved a message that it could not connect to a socket and that the file I was trying to play did not exist. i triple checked that it was correct and tried another file and same result.
Anyone else have this happen and/or know how to correct it?

some other peculiar behavior is that Mplayer still works in myth but will not playback HD content only SD, but there is no sound. I do get sound when watching live TV or outside of myth. all my settings are the same as they were before.

Can you post the command you were using to play the video file ?

Plus the line in mythfrontend setup for video playback.

September 11th, 2009, 11:30 PM

the command was just mplayer /file/path/file_name
the line from Myth is the default of mplayer -fs -zoom -quiet -vo xv %s

This will probably have nothing to do with your problems but you're not using vdpau with mplayer. To do that your command line will have to look like this

mplayer -fs -vo vdpau -vc ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau, file.ext

For myth:

mplayer -fs -zoom -quiet -vo vdpau -vc ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,

i wouldn't apply patches, just recompile using his repos. am using 190 beta drivers from jeans repos(testing) and found them to be much more stable than the 185 drivers fwiw. as said you must create a vdpau playback profile to utilize it.

Also if your drivers are showing in your xserver settings it sounds like your using them, even though they aren't showing under hardware drivers. happened to me and i was missing the modaliases, but still using the new/upgraded drivers iirc.

I just did a fresh mythbuntu 9.04 install and immediately upgraded to VDPAU using jyavenard's repo. Most of the time it works fine, but sometime the frontend gets into trouble. I have a plethora of errors and crashes when watching LiveTV or recordings. Here's some:

Watching Live TV mythfronend.log

Hi,

i totally don't want to hijack this but have a questin. I had a manual installation of 185.18 drivers with which vdpau worked. it made a mess of every kernel upgrade etc, so I decided to go back to 180.60 package and try the trunk repo by the esteemed JYA.

Now vdpau no longer initialises - not sure if this is the right word but that is what it feels like:

mplayer -fs -vo vdpau -vc ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau, a.ts

same thing also appears with myth

when I run the vdpau info tool, or rather try and autogen the latest version 0.0.6:
checking for VDPAU... configure: error: Package requirements (x11 vdpau >= 0.2) were not met:

No package 'vdpau' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables VDPAU_CFLAGS
and VDPAU_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I have tried to see how to find what to do but am at a bit of a loss (and yes I have reinstalled libvdpau and all 180.60 files a couple of times)

any help very welcome

half between a note to self and a help for anyone else who might run into to this (yes I managed to fix it!)

first all my libvdpau symlinks were busted, I just manually started hunting for all the old versions and then replaced them with the links to 180.60 version:

check this in /usr/lib/ (and lib32 and lib64 if needed) ls -l | grep vdpau
that spat out wrong links, which I delete with sudo rm xyz and rebuilt with sudo ln -s libvdpau_xyz.180.60 libvdpau_xyz (of course xyz stands for a numer of different libs)

then I ran into the problem that I could not open the nvidiactl
NVIDIA: could not open the device file /dev/nvidiactl (Permission denied).

check that /lib/udev/rules.d/50-udev-default.rules has an Nvidia block that contains that nvidiactl and points to video group

mine looks like this:
# graphics
KERNEL=="agpgart", MODE="0600", GROUP="video"
KERNEL=="card[0-9]*", NAME="dri/%k"
KERNEL=="pmu", GROUP="video"
KERNEL=="nvidia*|nvidiactl*", GROUP="video"
SUBSYSTEM=="graphics", GROUP="video"
SUBSYSTEM=="drm", GROUP="video"

after I checked that access to the video device was fixed by adding the required user to the video group

sudo usermod -a -G video YOURUSERNAME
check with
grep video /etc/group

reboot

I just downloaded the deb package mythbuntu-repos_2-0ubuntu0+mythbuntu5_all.deb and installed that, selected "weekly builds", and did an update. It looked like it updated some nvidia and vdpau stuff.

Now when I try to start mythfrontend all I get is:
Code:

/usr/bin/mythfronend.real: error while loading shared libraries:
libvdpau.so.1: cannot open shared object file: No such file or directory

myth will no launch. Any ideas?

Now I see that earlier, jyavenard warned :
Warning, do not activate the mythbuntu weekly build repository. The weekly repository is updated every week, and due to the nature of SVN ; each week the version number will increase ; even if there has been no changes in Mythtv 0.21-fixes.
If you activate the mythbuntu weekly build, it is likely that at some stage the weekly repository will update mythtv and will remove the VDPAU mods.

Well this is exactly what I did, and its turned my libraries into a hodgepodge mess of I don't know what. I didn't realize that enabling weekly builds would mess up the vdpau stuff, so how do I just get back to a working system?

Take the weekly repo out of your list of sources. Remove all mythtv packages and reinstall it.

Take the weekly repo out of your list of sources. Remove all mythtv packages and reinstall it.

If you are using my nvidia driver packages ; to be able to use mythbuntu default packages you need to install the libvdpau0 package.

I explained why here:
http://www.avenard.org/media/Ubuntu_Repository/Entries/2009/10/4_VDPAU_packages.html

All the vdpau related packages on my repository are currently being rebuilt, there's a few of them so it takes a while...

Installing libvdpau0 + nvidia-xxx-libvdpau on my repo is all you need to keep compatibility with mythbuntu packages.
If using my repository it's all automatic
