XINE also won't play the resulting un-plexed video file. XINE _will_ play the original. > have you tried "file" on the m2v file? $ file mov03d.m2v mov03d.m2v: data That's all it says. > Are you able to make the file available? http://pages.suddenlink.net/curthowland/mov018.m2v http://pages.suddenlink.net/curthowland/mov018.mpg This is the original right off the camera, and the file created with mplayer -dumpfile "mov018.m2v" -dumpvideo "mov018.mpg" It's only 6M rather than 20M with the clip mentioned earlier, but they're all showing exactly the same behavior. > If file reports "data" or something other than MPEG sequence, then > mplayer hasn't demuxed the file properly or has included corrupted > data at the start of the file. Well, there we go. That would also explain why XINE cannot play the resulting video. > You could try using bbdmux (part of bbtools) > http://members.cox.net/beyeler/bbmpeg.html , to demux the camera > file. > (source is available and I've had it compile it on linux and osx) > > Or you could use ffmpeg to demux the file: > > ffmpeg -i example.mpg -vcodec copy example.m2v ah-HA! Using the ffmpeg command above, I get: $ file mov03d.m2v mov03d.m2v: MPEG sequence, v2, [EMAIL PROTECTED] interlaced Y'CbCr 4:2:0 video, CCIR/ITU NTSC 525, 4:3, 29.97 fps > The format looks OK, so you should not need to re-encode it. dvdauthor chokes when I try to use the files directly, so there is _something_ that needs recoding (or at least tweaking). Why JVC decided not to write vanilla MPEG-2 files is beyond me. I just don't grok the proprietary-file-format mind. Thank you for the ffmpeg command. I'm going to try substituting it for the mplay video dump and see what happens. I'll reply with the results to the list, just to make sure it's all together for reference, even though the indications are it isn't an mplex problem.
