Are you talking about FFmpegFrameGrabber?

If this is indeed about FFmpegFrameGrabber as I am pretty sure it is, please 
try the modifications posted at issue #162.

Or if this issue is about something else entirely, please let me know.

this hapens if av_seek used with flag AVSEEK_FLAG_ANY, so it's not on keyframe 
and decoded frame(P or B) represent only difference from I-frame or previous P 
frame.
