Whether you decode the video or not is unrelated to your ability to replace the SEI and replace the captions. You'd still need to know the reordering though. Unless you are talking about mov which is the only container that has a special closed captions stream. > Yes, that's one of the things that make it complex to implement. > But the parser certainly has all the information to do the reordering. It would have to do some low-level parsing to handle complex b-frame patterns. VLC uses a guessed B-frame pattern and as a result is not frame accurate. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
