Hello,

I'm encountering some troubles while playing .avi files with vlc.
Coming from Ubuntu 7.10, I migrated recently to way faster Vector linux 5.9 std gold and the sole problem i get concerned this multimedia decoding.
I tried to play avi files, that played like a charm under ubuntu and VLC 0.8.6, on vector linux and VLC 0.8.6 (vl 5.9 package) and i just get sound and no videos.
Problem is that Mplayer and Xine do not play this files either (but in ubuntu they did).

Any suggestions will be very welcomed.

Thank you very much!!

No suggestions, but it looks like something may be wrong with our ffmpeg version then, since all 3 of these players use ffmpeg to decode. There's probably support for a particular codec missing. Can you try the following on one of the files that doesn't work for you:
Code:
ffplay (filename) -stats
and post the "Stream" info in the output? Should look something like this:   
Quote
Stream #0.0: Video: mpeg4, yuv420p, 384x288, 25.00 fps(r)
  Stream #0.1: Audio: mp3, 44100 Hz, stereo, 128 kb/s

Most music on my soundcloud page was arranged in programs running on VL.

The headacher,

here is the result of ffplay -stats

Input #0, ac3, from 'by.bb23.S01.13.Une.soiree.d.enfer.avi':
  Duration: 06:32:40.3, bitrate: 80 kb/s
  Stream #0.0: Audio: liba52, 32000 Hz, stereo, 80 kb/s
No accelerated IMDCT transform found
[liba52 @ 0xb7dd7450]Error decoding frame
[liba52 @ 0xb7dd7450]Error decoding frame
[liba52 @ 0xb7dd7450]Error decoding frame

[liba52 @ 0xb7dd7450]Error decoding frame
[liba52 @ 0xb7dd7450]Error decoding frame
etc.....

I try to run vlc on the terminal on the same file:

VLC media player 0.8.6d Janus
[00000275] main decoder error: no suitable decoder module for fourcc `XVID'.
VLC probably does not support this sound or video format.
[00000254] main playlist: stopping playback

It appers so that problem comes from a missing xvid codec, but xvid is installed ( xvidcore 1.1.3-i586-2vl59)

are there other packages needed?

That's odd.  Ffmpeg's xvid IS enabled:

I used ffplay with "-stats" to play a xvid with success until I stopped it:

Maybe you should try to reinstall ffmpeg just in case the files got screwed up?

Edit: Just to satisfy my curiosity, could you post the complete output of:

ffmpeg -version
Please ?
