![]() ![]() There was a branch for ffmpeg to add segment linking support, but I have no clue what the disposition was. I would guess, based on light research, that playback support would be limited as well, as many devices likely just implement basic Matroska support and this is a more advanced (read: obscure outside of certain anime circles) feature of the container.Īfter that, I tried using ordered chapters in two different editions (which basically creates two "titles"/chapter lists in the same file). This was an interesting test, since I concatenated all of the branched segments into one hunk of video and just used chapters as playlists and the chapter start/end times to segment them rather than using segment linking. Second edition chapters - ch1 starts at 41secs, ch2 starts at ~82secs.First edition chapters - ch1 starts at 0sec, ch2 starts at ~82secs.Two editions (ordered chapters flag set) and chapter sets.One video stream, combining all three segments in numerical order, so each segment's video starts where the previous segment's ended (e.g.Segment 3: Planet fly-by sequence (~7mins).Segment 2: French text intro (~41secs, identical runtime to seg 1).I used the first two segments of Rogue One for the test since it has several intro segments (one for each language provided). This setup worked really well for straight playback locally for the most part (requires a keyframe at the start of each chapter and a few other quirks to consider for it to do so, but it worked). This time, VLC played fine, but MPC-HC ignored the second edition entirely and just played the entire video stream with wacky chapter positions (ffplay did the same). Transcoding it on-the-fly would be problematic for a few reasons that I won't get into - most notably, ffmpeg utterly ignored everything except the first edition and dropped the ordered chapter flag, which essentially broke the nicely-ordered playback of even the first edition.as well as a few other oddities. It would also need to seek a lot to transcode any particular "edition".doable, but silly. Segment linking would be clearly better, but that seems like a no-go as noted before. ![]()
