We can try to make it as small as possible, but there will always be some extra latency. Plus, ffplay does a lot of things that might interfere with the use, like keeping the frames in sync with their announced timestamps, like a -re option that cannot be disabled. Also, the long-term plan for people who work on lavd has always been to try to replace SDL in ffplay by lavd. It has not progressed very fast, but it is a goal. This is a step in the wrong direction. -- Nicolas George _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
