I frequently create videos from png sequences using avconv by running:
avconv -r 24 -i images%6d.png -vcodec qtrle video.mov
Since I've upgraded to 14.04 I cannot play back them any more. Not with totem, not with mplayer.
totem show only the first frame, and nothing happens when I press play.
mplayer reports:
Dropping frame with size not matching configured size
Too many buffered pts
Same videos play fine with totem on 13.10.
