I play some videos using my player, the beginning of few frames are almost
gray. ffmpeg prints some messages:
Error number 3062 occurred
Error number 635 occurred
[mpeg4 @ 0238bb60] warning: first frame is no keyframe
the first picture type is AV_PICTURE_TYPE_NONE, then followed by lot of P
and B. The picture keeps gray until I frame comes.
I tried other players such as mplayer to play those videos, no problem. So
there must be some problems in my code, but i have no idea.
What seems to be the problem?
Here is my player: https://sourceforge.net/projects/qtav
