Something is wrong with this file

[kakomu]

I've been encoding the simpsons season 6 DVDs.

I'm using Xvid H.263 @ 700kbps. OGM file container. 2 Ogg audio tracks, both at 44.1khz. One at 80kbps, the other at 45 kbps.

Anyways, here's a clip of the problem area:

https://netfiles.uiuc.edu/methomps/www/temp.ogm

The video appears to be fine, but during playback, I get an error and the player has to be closed. WMP 6.4, WMP 10 and MPC all get the same error.

I've traced the error to the first audio track (the 80 kbps one) and libavcodec for Ogg decoding. The tremor codec in FFDshow does not, however.

I've re-encoded the video already, so that's not the problem. I've re-encoded the audio a few times using OggdropXPd. Q = 1, 1.01 and 1.5 all produce errors in that clip. Q = 2 does not, however. Neither does wav or mp3.

switching the audio to the second track for the duration produces no error.

So, I'm confused WHAT is going on that libavcodec will freeze at an exact point consistently with ogg audio encoded at q=1-1.5?

I dont had any type of error while play these files in MPC. I change between the two audio tracks well and the video was also fine.

If you mux it in matroska works?

I don't know why you're using OGM like Caroliano said, it's not like there are any hardware players with OGM support (if I'm wrong here, please correct me.

You say you're using "OggdropXPd" to encode the audio...you can try using BeSweet + BeLight/BeSweetGUI to transcode the audio, and see if that fixes the trouble.

But I would not encode in OGM thinking about compatibility with standalones. And if compatibility with standalones isnt an issue, so I prefer Matroska.

[kakomu]

Did you guys use FFDShow AUdio with libavcodec as the decoder for Vorbis?

As for standalones, I use a media computer I built specifically for my living room, so the question is moot. Anything compatible on my computer here is compatible with that computer.

* DaveEL is making it true. Expect a release of avs2matroska in not so far future, with xvid.dll dynamically linked and writing native matroska MPEG4 (File: http://daveel.leffe.dnsalias.com/broken/mp4.mkv )

in both MPC and Bsplayer, with Haali Splitter (18th sep 2005), it does not play it.
MPC stopped at 3:17, and bsplay, can't load it.

No problems with audio stream switching here either....

I also burned the .OGM file to CD~RW and span it in my Pioneer DV-575A... And it works fine in there too :)

I wonder why it says "broken" in the link. I doubt you can trust native MPEG4 ASP files that were made more than 2 years ago for validity. All muxers still use VFW mode for MPEG4 ASP. So yes, the file is broken... big surprise :p.

I don't see why the file should be longer than 3:17 according to you though...
