## Detailed Description

The channel media options.

Agora supports publishing multiple audio streams and one video stream at the same time and in the same RtcConnection. For example, `publishAudioTrack`, `publishCustomAudioTrack` and `publishMediaPlayerAudioTrack` can be true at the same time; but only one of `publishCameraTrack`, `publishScreenTrack`, `publishCustomVideoTrack`, and `publishEncodedVideoTrack` can be true at the same time.
