H264+Opus

Unidirectional elements

Example

In this example, we use rrwebrtcbin to send a video stream and an audio stream, then rrwebrtcbin receive the video and audio streams.

Bidirectional elements

Example

In this example we use two rrwebrtcbins, each send a video stream and an audio stream, and receives each other video and audio streams.
