audio/subtitles

[yaroslavlvov]

I want to simplify audiotracks/subtitles selection

• Want to provide something like this

Subtitles var currentSelectedSubtitle: ModernSubtitle { get } getAvailableSubtitles() -> [ModernSubtitle] selectSubtitle(ModernSubtitle)

AudioTacks var currentSelectedAudioTrack: ModernAudioTrack { get } getAvailableAudioTracks() -> [ModernAudioTrack] selectAudioTrack(ModernAudioTrack)

Where is the best place to implement this according to the current implementation Guessing as part of PlayerMediaItem Protocol and cast it when getting currentMedia from ModerAVPlayer instance

As I think you did, I read apple article: https://developer.apple.com/documentation/avfoundation/media_playback_and_selection/selecting_subtitles_and_alternative_audio_tracks

I think we could work with ModernAVPlayer Plugin System (PlayerPlugin):

• Media is loaded, plugin system call: func didLoad(media: PlayerMedia, duration: Double?)
• I can add a AVPlayerItem (from custom protocol) param to this method
• Then in the plugin, you can download group and options
• Then use the AVPlayerItem to select group and options previously download

In this case, I just have to provide in didLoad player plugin method the AVPlayerItem previously loaded.

For information, add PlayerPlugin is done on ModernAVPlayer init

what do you think ?

As I understand I can cast PlayerMedia to PlayerMediaItem in this method, right? Not quite get why there are two separate, however, plugin system will work for me, I was just thinking that this feature could be useful for others potentially and worth implementing internally

ok, I just created a new branch -> you can now use it to access AVPlayerItem and AVAsset when item is loaded and call all methods suggested by Apple

I suggest you create a new GitHub open source repository to create a swift package for the plugin. (can be access by anybody, to use or update it)

• Create a new Swift Package Project
• Create your plugin code
• Use ModernAVPlayer repo or another one to create iOS example to test it ** Inject your plugin in ModernAVPlayer init ** Access to AVPlayerItem from didLoaded delegate method ** Start async task to download group and options ** Choose options you need (you will have iOS example in the project) ** Apply from AVPlayerItem select method

If you have any question, please ask !

PS: do not pay attention to unit tests, I had to adjust them...

HI @yaroslavlvov ,
