Comment (by thilo.borgmann):
Two patches uploaded:
For the historic revision "ee30cda", waiting for a keyframe flag before
handling P-frames fixes this issue.
For todays todays revision "fca435f", this does not work anymore because
the keyframe flag seems to be handled differently. I don't know how to fix
the demuxer(?) or even if it is a demuxer mishandling of the keyframe flag
or just a broken file with wrong/missing keyframe flags.
