问题
I tried to Play MultipleAudioTrack in Roku. I refer to this Example to play an audio track. I same code use in my stream Here ?"m.video.availableAudioTracks :"m.video.availableAudioTracks but here not available any track. my stream check in VLC MediaPlayer. Here two-track available But I not found in Roku. My Audio Format is AAC. I also Set Here m.video.audioFormat = "aac". Any other Configuration required to Playing a multiple Audio.

I'm not certain about Audio files, but I know that Rokus don't allow you to buffer more than one Video at a time. This effectively means that a Roku cannot play more than one Video at a time.
The same could be true for audio files but I am not certain.
