Yep. Start anywhere, approximate seeks (MJPEG frames doesn't differ all that much in size) and do some syncing once you're at the approximately correct place, if you need precision. > MPEG does that, but MPEG isn't really a > directly captureable format. The PVR250/350 people does it by cating /dev/video. :) > Matroska claims to be that, but I don't > think it works.

It may be RIFF, Quicktime, movtar or MXF; as long at it's easily resyncable, it's fine with me. :) > think mplayer can read those broken files of yours and simply reparse > them and output a valid file. An unfinished lavrec file is not recognized by mplayer in any way. lavrec will write a 2048 bytes header consisting of zeros, and only fill it in when exiting in a controlled manner. mplayer _might_, I haven't experimented with it yet, be able to read a file while it's being captured if lavrec began with a very sparse RIFF header (<RIFF><zero length><AVI ><LIST> and so on), filling in the chunk sizes at exit. /Martin ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
