HOWTO: Auto transcode MYTHTV recorded shows to DVD, XVID or DIVX cutting out the co

[usererror]

this is exactly what i've been looking for. I'm now converting test nuv tv recording to xvid to see how it looks with just the defaults.

thank you very much for this how to!

[Anubis]

I believe I have everything in order, thanks for the guide!

I wish I could create a decent divx file though. Every divx file has massive artifact attack. I'd like a decent divx file for the ps3 to be able to read.

I'm sorry to dig up an old topic like this, but I am at a loss. I've tried it with the default nuvexport config, and I've tried it with the one provided in this thread, and I cannot make it work!

The nuvexport-xvid debug information is here: http://pastebin.com/m5ca42340 (and yes, I'm aware that the debug information is for a different show, none of them will encode)

I can write to the destination... and I'm mystified... the same nuvexport that I tried on this worked with knoppmyth for months before...

This is on Mythbuntu 8.04 Beta 3, yes, I'm aware that it's a beta, however, I recompiled ffmpeg as per the instructions here.

Hi There. I have a mythtv newb question. I've just installed nuvexport and have ieved the following error:

---
myth@myth-desktop:~$ nuvexport
Couldn't communicate with 192.168.0.54 on port 6543: IO::Socket::INET::MythTV: connect: No route to host

Cleaning up temp files.
---

192.168.0.54 was my DHCP given IP address at one stage.. But now it's giving out 192.168.0.58.

What config file is it using to grab this Ip address? I can't find the IP in any config file under /etc/mythtv.

At the same time my mythtv frontend has also lost access to the backend. So I assume this is not nuvexport specific.

Any help apprecieted!

Mick

You really ought to start a new thread... Have you tried running mythtv-setup?

[mickfromperth]

Hi guys. Wouldlike to say thanks forthis Howto. It's been really helpful. It looks to my like there is a gap in MythaTV which is how to auto-shrink your HD recordings so something like mp4 or avi that it seems only this script currently fills. I'mrelatively new to myth so letme know if I'm wrong.

I have followed the guide and can get this to work great from the command ling. However.. Running as a user job I get the following in my logs. What they hey is calling config.xml????

Mythtv uses the sql database for its config. nuvexport uses /etc/nuvexportrc.

I've gone to line 36 of nuvexport.. and it is asfollows:
---
# Load the MythTV object
use MythTV; <-- I think its this line
our $Myth = new MythTV();
---

Bit MythtV aint an obnect in the script so I'm at the end of my skills here..

Please help!

OK I've fixed that. Just needed to run mythfrontent. It seems to log it's DC config.xml into /home/username/.myth/xonfig.xml.

Heres mine:

I didn't create that filebut I did check it. The usernameand password are correct. Note though that the port is 0. Which is not correct it should be 3306. I guess 0 means default though, as from the output bellow,it's using the correct port.

Any tips on why it's failing to connect via localhost?? I Access Denied imples myth-backend is rejecting it. But there is not log event of this occuring???

Is there a config variable I'm missing??

I have asked a couple of times...let me try again.

1. I would like to automatically transcode my recordings to xvid, place them in the recordings directory, delete the original .mpg file and be able to play the xvid through mythfrontend. Is this possible? How do you get around the fact that the database will be pointing at the .mpg file which will no longer be there?

2. Is anyone willing to tackle the following? (Assuming you are transcoding to save space on your hard drive) Because automatically transcoding every recording is taxing on the CPU, wouldn't it be great if there was a way to transcode only files that are some prescribed age or older (say one week)? In other words, if you watch the show and delete it within that time period, you watch the original .mpg, but if it sits around for longer than that, it gets transcoded to save space! Any takers? The solution will have to allow for reboots and restarts of myth-backend.

I know the second request is probably quite complicated, but I would love someone to at least comment on the first request.

Thanks.

Bump...

Can you use the method in this thread to transcode a recording and update the recordings database to point to the transcoded file?

I have asked this many times, but can't get an answer. I don't know how else to word it.

[se99paj]

I have had nuvexport setup for a while and I have been really happy as it works great.

But I have a slight problem with one recording, when I convert the video to Xvid the video is perfect and there are no problems, but the video is completely distorted, it sounds like it is being stretched. The original doesn't have this problem.

Does anyone have any idea why this could be happening?

I am using the settings that the majority of people use on here.

Thanks
