I play some videos using my player, the beginning of few frames are almost gray. ffmpeg prints some messages:<div><div>Error number 3062 occurred</div><div>Error number 635 occurred</div><div>[mpeg4 @ 0238bb60] warning: first frame is no keyframe</div>
</div><div>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.</div><div>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.</div>
<div>What seems to be the problem?</div><div>Here is my player: <a href="https://sourceforge.net/projects/qtav">https://sourceforge.net/projects/qtav</a></div><div><br></div>
