This page links to the GstWebRTC audio and video examples using PubNub.
H264+Opus
Unidirectional elements
Example
In this example we use webrtcsink to send a video stream and webrtcsrc to receive the video stream.
It seems that browsers do not get along with x264 because of SEI NAL units sent with the stream. As a workaround, we set key-int-max=1 and avoid the SEI insertions.

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