Sideload audio

[pigeonmal]

Summary

A source.audioTracks for sideload audio tracks.
I updated the patch for work on 0.77 react-native.

Motivation

#4374
#3265

Changes

Get sideload audio and merge all in one source for exoplayer, check commits.

Test plan

It's not perfect for now, for example in my code I didn't setup language of audio in the Reactexoplayerview.java.
In 6.8.2 I had a poster bug, when audio tracks and poster are set : Audio work, but the poster stay over the video.
I don't test in 6.9 if this is fixed, I will test.

Can you please add a section in documentation please ? I would like to test your change in source creation (side loaded subtitles) but it looks great 👍 thank you !

No problem, but I have 3 problems :

1. The name of the prop is source.audioTracks not just audioTrack. Except that for now in the documentation, there is no grouping of source props. So this can lead to confusion?

2. In sampleMimeType, how to add all available mime types check: https://github.com/androidx/media/blob/release/libraries/common/src/main/java/androidx/media3/common/MimeTypes.java

3. In my code I put that title, language, mimetype are not mandatory, because I have implemented only the mimetype for now. Should they be mandatory?

1/ there is a source prop here : https://github.com/TheWidlarzGroup/react-native-video/blob/master/docs/pages/component/props.mdx#source
But I agree this part of doc shall be clean up! it is already confusing :)
Bad doc is bette than no doc !

2/ The easiest is to redirect to exoplayer doc, no issue with that !

3/ you mean in that place:

            MediaItem audioItem = new MediaItem.Builder()
                            .setUri(track.getUrl())
                            .setMimeType(track.getSampleMimeType())
                            .build();

you can add setTitle and/or setLanguage of something like this ?
If that is the case, just add it and it should work !

4/ pas de soucis avec ton anglais, je cause franglais aussi :D
