I’ve a bunch of movies which are hosted on Vimeo. To permit customers watching them on the cell apps (Android & iOS) we use the m3u8 format given immediately by Vimeo.
It really works nice with expo-video as all our movies have transcript for various languages.
I want to enable the customers to obtain movies to allow them to be watched offline. To attain that I exploit ffmpeg to transform the .mp4 to .mkv and mix the .srt recordsdata.
This resolution works nice on android, customers can obtain movies and watch them offline with the power to pick subtitles. Sadly evidently the AVPlayer on iOS (utilized by expo-video) doesn’t help MKV. I attempted totally different codecs mov, mp4 containers, m4v the place subtitles present correctly on VLC after conversion however not on the iOS participant. (both no subtitles in any respect, or solely the primary monitor).
Is there a file format supported by AVPlayer that enables a number of subtitle tracks?
