We have a way to detect Dolby Vision vs HDR10 vs HLG vs SDR, but what about detecting if has Dolby Atmos?

Dolby Atmos 应该是指音频方面的。Dolby Vision vs HDR10 vs HLG vs SDR是视频方面。所以你要判断是否 atmos的话，那应该是要判断音频的格式。我不知道我的理解对不对。我从网上看的资料是这样说的

Yes I know it's the audio aspect. That's why I'm saying that we have a way to detect the video quality but not the audio quality. Thx

@matteogobbi 那你可以用mediaSubType 或是MediaPlayerTrack.descriptioncodecType 来判断音频的格式
