When converting a Canopus HQ file to raw with a lower fps than the
original mencoder segfaults. I tried this with my own samples and with
the sample found at: http://samples.mplayerhq.hu/V-codecs/CUVC/
As long as -ofps is set equal or higher than the source fps there is no
crash but using any lower -ofps segfaults mencoder.
Following is the gdb output:
(gdb) r -v -nosound -oac pcm -ovc raw -ofps 12 -of rawvideo -o /media/out_video.yuv /media/canopushq.avi
