1021,ffmpeg goes berserk when trying to convert this video to mjpeg,matteosistisette,,"With the attached video (which is a 3gp video of 20 seconds, 10 fps, 480x640 resolution, h264 codec, for a file size of about 4 MB, I tried the following command:

ffmpeg -i VIDEO0024.3gp -vcodec mjpeg -s 300x400 -qmin 0.8 -qmax 0.8 VIDEO0024.mov

After several minutes, ffmpeg had processed more than 145357 frames, reported a time of 1.62 seconds, had written more than one GIGABYTE of output and was still working. I obviously killed it.

It looks like it gets the framerate completely wrong.


The exactly same command has worked just fine with other video files encoded with other codecs.
