Title:
ffmpeg goes berserk when trying to convert this video to mjpeg
Status in libav package in Ubuntu:
Expired
Bug description:
I have 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.
The exactly same command has worked just fine with other video files encoded
with other codecs.
I think the problem is that for some reason it by default uses an
output framerate of about 90000 fps. Adding -r 10 for the output fixes
the issue. But it is still an issue: according to documentation the
default framerate is 30fps, anyway 90000 is certainly not a reasonable
default.
I erroneously reported this in the FFmpeg bugtracker and they say it's
probably fixed in FFmpeg.
