Sorry, didn't want to bother with stupid questions. I've examined that there is no problems with input.h264 file in VLC player. After your answer I looked input.h264 in ffplay and found the same quality issues with blurred frames that was in output.mp4. So, the question is closed, now I understand the source of the problem and it is not connected with ffmpeg. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user
