iOS switching between audio & subtitle tracks added using ffmpeg
27 décembre 2019, par Tony MEdit : Title altered to reflect that the answer and comments by @llogan cover switching between both audio and subtitle tracks.
I have an
m.mp4
with English audio and want to add a second audio stream in Italian so that I can play either language using the iPhone. When I used this command :ffmpeg -i m.mp4 -i ita.mp3 -c copy -map 0 -map 1 out.mp4
the output from
ffmpeg -i out.mp4
(see below) shows that a new audio stream is added, and I can switch between audio streams using the VLC player. Yet when I transfer the video to the TV app and play it on either MacOS or iOS it only plays the original English and I see no options to play other languages.How do I get it to be able to switch between either audio on iOS ?
Here is the output from
ffmpeg -i out.mp4:

Multi-language broadcasting title metadata for Audio & subtitle is not working
28 septembre 2022, par Fariduzzaman XenarI have a (.mp4) video file that contains 1 video track, 2 audio tracks & 2 subtitles. I already used different titles for audio tracks on encoding, but it's not working on any web player like JWPlayer, or Flussonic, where Multi-language broadcasting is supported. It shows eng a1, hin a2 for audio | eng t1, ben t2 for subtitle


I want to show it like this English, Hindi for audio | English, Bangla for Subtitle
