dual-stream mode

In the dual-stream mode, the SDK transmits a high-quality and a low-quality video stream from the sender. The high-quality video stream has a higher resolution and bitrate, and the low-quality video stream has a lower resolution and bitrate.

Subscribing to low-quality streams improves communication continuity because this reduces bandwidth consumption. Developers can choose to receive low-quality video streams when network condition are unreliable, or when multiple users publish streams.

The SDK sets the default video profile of the low-quality video stream based on that of the high-quality video stream.
