Comment (by DonMoir): I don't know what the best solution is but clearly you do not want garbage to be displayed. This is not specific to H264. Now you have me wondering if my approach will fail on some clean videos with no keyframe. I consider this to be a bug and not a feature request. If you want another sample where the video is fine but initially gray I will upload it. A bug in the video file ? Probably. But as I said it tends to happen more often then it should so at least need some descent work around and it seems the only way is what I have already. This seems to happen only with ffmpeg based apps. If for example I use some other means like DShow and installed codecs, the gray frames do not appear and I assume this problem is worked around in the various codecs. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/472#comment:2> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
