I have tired that command: mencoder DVD.mpg -o test4.avi -oac copy -ovc lavc -lavcopts vcodec=mjpeg:vbitrate=15000 There mplayer tells me that I have used a MJPG coded. But it seems to me that they don't include a huffman table or at least in a different way.

Hallo Hope it's ok for Cc: you in my post to list. That's no Problem. No reason for excuse cause it's nothing of mission critical: I'm trying for fun ( and to expose my screencast for profiling ). With lives, I do this: File - Encode Clip as Next is to select the file name After that, to choose this as an encoder: http://pyotr.pisem.su/export-lives.png It appeared to be the fastest way to provide playable AVI, also. I don't know what mencoder creates, but the problem seems for me to be in mencoder. When I export a file with lives, with the option you show in the image. I can't play it back. mplayer prints out that information: AVI file format detected.

Look for the lines I have posted above. I should have more diags from lavinfo but it doesn't look to have a key for this. Versions are: === MPlayer 1.0rc2-4.2.1 mjpegtools-1.9.0.r3_2 lives-0.9.8.10_2 === I use live 1.0.5, mplayer 1.0rc2-4.3 and mjpegtools 1.9.0 sh -c mencoder -mf h=480:w=640:type=jpg -o tmpvid -ovc lavc -lavcopts vcodec=mjpeg:vhq -ovc copy -noskip -ofps 5.000 mf://*.jpg -frames 785 12 === Lives looks likely to keep its storage in a set of separate jpeg files in /tmp/livestmp Seems so.
