Howto setup a bt878 TV Card

[art2003]

This howto refers to a Modular Technology MM200PCTV TVcard but may help also with other bt878 based TV Cards.

It was written when I was running Ubuntu 7.10, it may need little changes to work with later releases.
Also I must mention I am a PAL user and have used it just with PAL devices, so for NTSC again you may need to tweak some
parameters.

With the card in your PC
type
lspci | grep Bt878

this is the output on my card:
0000:00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 02)
0000:00:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 02)

1) Make sure the module will be loaded
sudo gedit /etc/modules
add bttv if not already present

2) Options for the module. Create this file:
sudo gedit /etc/modprobe.d/bttv

# i2c
alias char-major-89 i2c-devb
options i2c-algo-bit bit_test=1
# bttv
alias char-major-81 videodev
alias char-major-81-0 bttv
# My TV Card
options bttv card=23 tuner=18 radio=0 pll=1 adc_crush=0


3) Install tvtime
sudo apt-get install tvtime
then run tvtime-scanner ; takes a few minutes

4) Running:
sudo modprobe bttv
and then run tvtime
at this point you should have black and white tv

to enable colour edit tvtime.xml

sudo gedit ~/.tvtime/tvtime.xml

I followed your steps until this:

vikernes@vikernes-desktop:~$ tvtime-scanner
Reading configuration from /etc/tvtime/tvtime.xml
Scanning using TV standard PAL.
videoinput: Cannot open capture device /dev/video0: No such file or directory


what can I do ? please help !

[PartickThistle]

If you have /dev/video do this;

sudo ln -s /dev/video /dev/video0

[domino]

Do you have to manually un-mute your line-in setting in Volume Control in order to hear TV sound? I seem to have a problem with this on Dapper which didn't exist in Breezy, no matter whow I conig /etc/modprobe.d/bttv.

WARNING to people trying this. I have a Twinhan VisionPlus HDTV PCI and this method caused ubuntu to hang consistently even in recovery mode. I had to use a livecd to repair it. The drivers are ridiculously buggy for this card.

Using a vanilla ubuntu setup, the card is detected, but NO device nodes are created (although dmesg says it does create a dvb0, this doesn't exist in the filesystem).

So if you have this card, don't bother with this method... I don't think there's ANY way to get this card going under ubuntu :|

[darnyte]

under ubuntu feisty all you have to do is install tv-time and it works.. no module setup or config. I am guessing that the module is built into kernel now.. don't know about audio haven't tested it yet...

Hi, I'am Milton from Venezuela i have a tv card lifeview with the conexant fusion 878A chip on it,
milton@milton-desktop:~$ sudo lsmod |grep videodev
videodev 29312 1 bttv
v4l2_common 18432 2 bttv,videodev
v4l1_compat 15364 2 bttv,videodev
Tvtime gives mi a blue screen someone know how to put this card to work in Ubuntu 7.10
Thanks

[gtr225]

Thanks for the guide, this worked perfect for my Maxron maxtv tuner card. Now I use Tvtime to watch satelite television on my computer monitor while I browse the web. However are there any programs that could allow me to record tv shows to my computer?

I think you might find this page at linuxtv (http://www.linuxtv.org/v4lwiki/index.php/TV_Recording) to be useful...


Now as a side note to get line-in working :(

Awesome, thanks for the link! Since I don't have a working line-input (something to do with a rear_switch that doesn't work) this reminded about the spare cd-in wires I have around somewhere. that might just do the trick

Thanks!

[ciroxyz]

thanks man, works great with kworld (v-stream) bt878 chipset... had to un-mute sound in volume controls...

cheers

[bscabl]

i almost have it all working, except...

Scanning using TV standard NTSC.
Scanning from 44.00 MHz to 958.00 MHz.

says no frequency
and then when i start tvtime i have a fuzzy black and white channel, and thats it.. no channels and it says 'no frequency' at the top.. im missing one thing prolly and im not sure what it is...
ubuntu 8.04.. help?

Any help is appreciated.[/quote]

After months of working on this, I got it to work with sound and color until I grocked the tvtime.xml file as directed. Also wonders if the entry on there is for PAL, rather than the needed NTSC standard here in America.

Any insight at all?

=================
Quick update:
Rebooted and lost audio from BTTV; checked volume applet and all seems ok. Can someone please advise on what happened?

[art2003]

I definately have PAL, so I have no idea how my Howto should be changed to work with NTSC.

Although I still have the bt878 card, I no longer use it as I have newer hardware connected via HDMI to a TV

[art2003]

hello Paul,

run
ls /dev/video*

You probably have more than one device as your logitech webcam might be using one

also add the bt modules you can see from lsmod to the blacklist
and then load them manually with sudo modprobe until things work
then you can add the modules that work for you manually to /etc/modprobe.d/

Yes, in short VDR can do the job, but to watch satellite TV with it, best if you find an appropriate VDR howto.

I am of a mind to try this project:

/dev/video0 removed the camera, as it is one of those that the manufacturer dumped and does not support well. Pity

I have a Pinnacle PC-TV card which has the bt878 in it with Alpha 6 of Jaunty Jackalope. I also have a Logitech Quickcam webcam in the system. So there are more than one /dev/video(x) ports. You can get the video to work with this by using the device options on xawtv and tvtime like this:



xawtv -vbidev /dev/vbi0 -c /dev/video1 -C /dev/dsp -remote -global:filter "linearblend" -b 24 -gl



tvtime --device=/dev/video1 --frequencies=us-cable --norm=NTSC


My tv card is /dev/video1. The webcam uses /dev/video0. The problem I have is with sound. I can't get the sound from the tv card, but the video is fine. I'm guessing the sound from the tv card is on /dev/dsp1 or /dev/dsp2, but setting that with -C option on the xawtv command doesn't work. I've also tried the sox work-around with no success:



sox -r 32000 -t ossdsp /dev/dsp2 -t ossdsp /dev/dsp & pid=$!


My sound works ok otherwise, just not with the TV Card. I've tried both the /dev/dsp1 and /dev/dsp2, but it doesn't work for either one. I plan to experiment with setting different mixer configs to see if that help.

[pneaveill]

Guess I could have stated my issues a little more clearly: I have video and that part is wonderful. The problem is sound. I have tried the internal audio patch cable attached to sound card and without. I have checked all the places I could find to mute/unmute something.

Has to be something I am missing. But what?

---------- Update ---------
I tried your xawtv suggestion below there and got a bunch of silent static.

your tvtime suggestion gave me video but no sound (as I had before).

The sox one failed to find the ossdsp module

Try installing libsox-fmt-oss, libsox-fmt-alsa, libc6 from the terminal in order to get ossdsp. I forget the exact command, but lemme know if it doesn't work, and I'll look deeper into my dpkg and Synaptic logs. I have the same problem, no sound with tvtime, so I'm using sox, and initially it wasn't finding ossdsp. I'm thinking I'll dedicate a good amt of time to try and hack a solution to this problem soon.

In the setup you have video but no audio please
refer to this other howto of mine:
http://ubuntuforums.org/showthread.php?p=6960534#post6960534

Point 3, for installing OSS instead of ALSA which can be rather buggy

of course the line

ln -s /dev/oss/oss_hdaudio0/spdout1 /dev/dsp

would be different for you according to what works
but you can do
ls /dev/oss -l
to see a list of devices and try them one by one

I am not running hdmi, so do I really need to load oss? All I want to do is either run VGA or regular video to the screen. Why is this so complicated?

[art2003]

Well, OSS in general has better sound quality but some applications (for example Skype for linux) do not support it

You could also just try to update your ALSA to 1.19, there is a script in my other thread I mentioned before.
Also run alsamix and make sure nothing that matters is muted, if that doesn't do the trick then give OSS a try...

Not sure what happened, but I followed your instructions on setting up OSS and rebooted like it told me to. Upon reboot, I lost all sound. Could not find the actual link to redo the alsa. If you could point me in the right direction, would appreciate it.

Please understand that I am ticked at this column here. Everything was fine until I did your last couple steps on the first post. From that point on, everything that I did has made it worse. Is there a way to restore back to defaults without those last couple steps there on that first post without having to wipe/reload?

The last suggestion you had me do there for some reason dropped my channels from 50+ down to this:
Scanning from 44.00 MHz to 958.00 MHz.

Changed out both the card and the TV cable hoping that one of them was the issue, but have only those limited channels and no sound.

Please help

[pneaveill]

Can anyone help me get this thing to reset back to before I started without wiping and rebuilding the whole thing? I tried
sudo apt-get remove --purge each of the files and it supposedly removed them. However. once I went back to reinstall the stuff, the errors that I have been receiving all along are still there.

[tamashumi]

Guys, I solved sound problem by just skipping point 2) of this guide on Karmic

I mean remove or comment all in /etc/modprobe.d/bttv
Probably commenting 1 line inside or changing some param will be enough but I'm not sure which one and all works fine without any config for bttv module.

After changing module configuration you need to reload module.
Unload module:

sudo modprobe -r bttv
Load module again:

sudo modprobe bttv

Do this each time you change /etc/modprobe.d/bttv file for testing (if just removing doesn't help).

[Fitch]

My problem is as below:

I have had a 4 camera card for nearly a year now, no problem.
I have now had to install a second 4 camera card to cover the car park and corridors.

so I have card=77,105 on bttv.conf and that's it.

Needless to say, it doesn't work 'cos I can't remember what else to do.

The original 4 cameras are fine and work well. I'm just missing something... (actually, I know I'm missing /dev/video1 for a start!)

I did modprobe bttv and restarted, but all thats happened is that zoneminder is always stopped when it reloads, and it takes an interminable time to actually respond to any commands.

ls /dev/video* just comes up with /dev/video0
lspci | grep Bt878 just comes up with the original card.

[pickarooney]

I can't get my bt878 card (Hauppauge WintV) to pick up any channels in Lucid. It worked out of the box on Jaunty and previous releases. I've tried everything here and more but still I just get a blue screen. I don't understand why Lucid doesn't support my card.

brafferton@cameras:~$

I did modprobe bttv and restarted, but all thats happened is that zoneminder is always stopped when it reloads, and it takes an interminable time to actually respond to any commands.

ls /dev/video* just comes up with /dev/video0
lspci | grep Bt878 just comes up with the original card.

Fitch,

Did you figure this out?

I'm having problems with my cameras "rolling" up and/or down.


I did this ( taken from this (http://www.zoneminder.com/wiki/index.php/Pico2000) page):


options bttv card=77 tuner=4 radio=0 triton1=0 vsfx=0 autoload=0


Things seem better than they were but this "rolling" business is killing me.

Here's my dmesg for bttv.

Any advice so that my cameras don't roll?

I'll admit to not poking around a bunch with them so perhaps there's an easier fix. Just checking around. Thanks!
