Hello,
I am trying to take a video with subtitles, run it through ffmpeg with the “dash” output format and get ffmpeg to output the subtitles. Steps that I’ve taken: 1. I took this video: https://www.youtube.com/watch?v=QF8pM4wiLaY and downloaded the mp4 and srt files 2. I combined them with this command: bin\ffmpeg.exe -i "Prime Minister's Questions_ 25 March 2015\Prime Minister's Questions_ 25 March 2015 (480p).mp4" -sub_charenc UTF-8 -i "Prime Minister's Questions_ 25 March 2015\Prime Minister's Questions_ 25 March 2015 (480p).English.srt" -vcodec copy -acodec copy -scodec mov_text -metadata:s:s:0 lang=eng "Prime Minister's Questions_ 25 March 2015.mp4" 3. I then tried to dash the video with this command: bin\ffmpeg.exe -i "Prime Minister's Questions_ 25 March 2015.mp4" -vcodec copy -acodec copy -scodec copy -f dash out.mpd ffmpeg finds the subtitle track in the video: Stream #0:0(und): Video: h264 ([33][0][0][0] / 0x0021), yuv420p, 854x480 [SAR 1:1 DAR 427:240], q=2-31, 659 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac ([64][0][0][0] / 0x0040), 44100 Hz, stereo, 253 kb/s (default) Metadata: handler_name : SoundHandler Stream #0:2(und): Subtitle: mov_text ([8][0][0][0] / 0x0008), 0 kb/s (default) Metadata: handler_name : SubtitleHandler But the subtitles do not appear as a track in the resulting out.mpd file or segment files. I tried using the –adaptation_sets option to force it but it didn’t seem to do anything. Are subtitles supported in the “dash” output format? Am I doing something wrong?
