Turn On The Large And Small Streams

enableDualStream

• A brief description - Turn on the large and small streams

SDK support, multiple video streams sent simultaneously. - Large and small streams: Since Android mobile devices can only open one camera to capture video, the local device will capture high-resolution video (the local video capture resolution must be no less than 720p). Then, it will be split into two video streams. One is of high quality, called the large stream, and the other is of low quality, called the small stream. Both video streams will be published simultaneously. Due to the significant performance consumption, use this feature with caution.
