Custom m3u8 for map audio #27

Open rudnypc opened 2 years ago

rudnypc commented 2 years ago

When video has multiple audio, maybe it would be nice if we can choose the best audio language, the ffprobe can give all index audio.

rudnypc commented 2 years ago

Generate m3u8 for custom video, audio and subtitle index could be nice too.

m1k1o commented 2 years ago

As separate manifest? E.g. profile-eng.m3u8 or joined together in one playlist as multiple audios?

rudnypc commented 2 years ago

It's a nice idea, but how it will work if the video has multiple audios in english or unknow language? What do you think in profile-eng-00.m3u8, profile-eng-01.m3u8 and, profile-ger-00.m3u8, profile-por-00.m3u8, profile-UNK-00.m3u8, profile-UNK-02.m3u8?

unk=unknow

I'm thinking if will be easy at the transcode to know the right index to use.

m1k1o commented 2 years ago

Yes, I agree, stream index could be used. And then maybe either using filter options as query parameters or in the name of manifest.

profile-0.m3u8 profile-1.m3u8 profile-2.m3u8

0,1,2.. is the index. Inside the master playlist, you could put the language name/details.
