Unsupported compression for MPGA

[The.Modificator]

Hi everybody!

I just registered here and - of course - have to start with a problem/question rightaway.

I'm using MythTV to record and watch TV. MythTV generates .nuv files which seem to contain a video track that is RJPG encoded and (at least when MythTV's settings are set to uncompressed audio) an mpga audio track. Watching those .nuv files is not a problem at all, but it's not as great as if there was audio as well.

Since Windows Media Player (sorry to mention it here ) can play the audio in those files without any problems, it seem to be caused by something on VLC's end. To get an idea what this problem is caused by, I took a closer look at VLC's message output (verbosity level set to 2):

The highlighted error message repeats like a thousand times after that.

So what should I do? According to the message and this kinda old post I should provide an example file so that some of the developers can have a look at it. Is that still the case?


Thanks,

Yes, share the file with us.

Here's a 46 sec sample recording: http://www.gigasize.com/get.php?d=g84pxygn1wd (43.65 MB)
EDIT: The file is gone.

EDIT: Just tested it on my Linux machine as well - seems to be an OS independent problem. Could a moderator please move this post to the general problems forum?

Topic moved as requested.

So has anyone already found out if this is a problem with VLC or a problem with the file? (Which would be strange since Windows Media Player plays the file.)

[javakab]

Its been several months. This problem still persists. Can someone provide status ? Or, is there a work around. I was wondering if forcing the audio to be compressed by Myth would make it processable by vlc .

- Thanks

Yes, that's what I figured out. Just enable audio compression and VLC will play the files recorded since the change of the setting. It's just weird that the uncompressed files won't play in VLC.
