Have you considered looking at the documentation? https://www.ffmpeg.org/ffmpeg-all.html Particularly in this section: https://www.ffmpeg.org/ffmpeg-formats.html#Format-Options I believe the maximum value depends on the timebase and on the format, you should just give it a try first. > I've tried: ffmpeg -i source.iso -target ntsc-video source.out > > ffmpeg quits quickly with a series of error messages: The full, uncut console output of $ ffmpeg -i source.iso -analyzeduration M -probesize N (using your choices of increased M and N) could be very helpful. What also comes to mind: - There may be junk at the beginning which ffmpeg can't interpret. That could be cut away. But we wouldn't know with a (sub-)sample. - vlc can not only play, but also output to a stream (to be piped to ffmpeg) or even convert/re-mux itself, using ffmpeg's libav libraries. If only vlc masters to "see" the video, that would be a good choice.
