I seem to have broken something on my system, I'm sure AVI files *used* to play OK.
When I try opening them with either mplayer or with totem they just show me the first frame and that's it.
With totem I can drag the time slider across and the movie plays so decoding would seem to be OK, it's just that it doesn't play automatically.
Any ideas what might be wrong anyone?

"An AVI file may carry audio/visual data inside the chunks in virtually any compression scheme, including Full Frame (Uncompressed), Intel Real Time (Indeo), Cinepak, Motion JPEG, Editable MPEG, VDOWave, ClearVideo / RealVideo, QPEG, and MPEG-4 Video." says http://en.wikipedia.org/wiki/Audio_Video_Interleave
So it depends whether you have the right codecs for those AVI files. Maybe you uninstalled some codecs somehow? Without more info, I don't think anyone else will be able to tell. Maybe useful: http://www.chiark.greenend.org.uk/~sgtatham/bugs.html
Hope that helps,

Surely since it plays OK when I drag the slider across the codecs must be OK, otherwise it wouldn't get decoded at all.
Re the second link, given that I'm fairly naive as regards video I need feedback to enable me to ask more intelligent questions.
Running mplayer on one of the files says:-
chris$ mplayer mvi_0823.avi MPlayer SVN-r1.0~rc3+svn20090426-4.4.3 (C) 2000-2009 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support. You will not be able to use your remote control.

Now there are errors in there but on the other hand mplayer does seem to think it can handle things (so it seems to me), however I'm quite willing to be told otherwise.

.... maybe relevant, this is xubuntu 10.04.

This is quite worrying...

Maybe the video has some weird errors in it?
Maybe play it with -v option to get some more verbose info?

Actually, my install of MPlayer does this too, but with port 310 - so maybe this is normal?

Yes, this is part of the problem, all those error[ish] messages and you don't really know whether they're important or not.
I've installed VLC and that plays the videos OK (after asking it can 'repair' them) so I'm sorted for the moment. It's not as if it's a big issue, it's basically a few pictures in my photo album that happen to be videos because I pressed the wrong button! :-)
