Just in case anyone finds this in the future, the eventual solution to this issue (for me, I don't know how applicable it is generally), was to add -ss 0 to the ffmpeg command:
ffmpeg -discard nokey -ss 0 -i input.mp4 -c copy -y keyframes.h264 I'm guessing the input stream has weird timing information or something. -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
