I really appreciate all of the responses so far. The one command that I have found that gives me most of what I need is:On Thu, 2008-03-27 at 10:05 -0430, Patrick O'Callaghan wrote:On Thu, 2008-03-27 at 08:21 -0400, James Pifer wrote:On Wed, 2008-03-26 at 22:26 -0430, Patrick O'Callaghan wrote:On Wed, 2008-03-26 at 16:16 -0700, Paul Lemmons wrote:I am looking for a way to look at an AVI file and see how it was encoded with enough detail that I could reproduce the process using transcode or mencoder. I have a media server (D-Link DSM520) that plays most videos absolutely perfectly. Some, though, it has trouble keeping audio sync. I would like to compare the videos that work without issue to those that have issues to see if I can identify what the differentiator might be. I should then be able to identify those with problems and re-transcode them to look like the files without the problem. That is the goal, anyway.I suspect this is real easy but I am just not finding it and I am completely Googled out. Any pointers in the right direction would be much appreciated!The tovid package ("yum install tovid") has a command called idvid, which might be at least part of what you want. pocI was/am in a similar situation trying to figure out a way to transcode videos for my son's Zune. So far the only tool that has worked is crappy MS Movie Maker. Anyway, I found this windows tool which I think is free:GSpot. Just google and it should be the first thing returned.I will check out tovid as well!Note that most Linux transcoders are simply frontends to parts of the 'transcode' package, which has a zillion options and can almost certainly do what you want if you can figure it out :-) ffmpeg is also useful and somewhat simpler.transcode has tcprobe, which tries to get information about audio and video from a media source. He also indicated that he might use mencoder, which implies that he might have mplayer as well. Running mplayer in a console with the -v flag set gives you a ton of information about what's playing.

mencoder -msglevel all=6 myfile.avi -o /dev/nullIt errors out but before it does it drops a lot of information about the file.
I will try tcprobe when I get home. I don't have any of the problem avi's here at work.
