Thank you. I just did a bare-bones test like this and it worked:
ffmpeg -i input.avi -vcodec mjpeg -b 16000k -acodec copy ffmpeg_test.avi
However, with MEncoder and looking at the the bottom of the Man page, it
gives an example:
The same, but with MJPEG compression:
mencoder dvd://2 -o title2.avi -oac copy -ovc lavc -lavcopts
Experimenting with the vbitrate of 1800 up to 24000000 made no
difference and defaulted to some set rate.
Before MEncoder became unmaintained, did this ever work?
