rtcp-processing

rtcp-processing demonstrates the Public API for processing RTCP packets in Pion WebRTC.

This example is only processing messages for a RTPReceiver. A RTPReceiver is used for accepting media from a remote peer. These APIs also exist on the RTPSender when sending media to a remote peer.

RTCP is used for statistics and control information for media in WebRTC. Using these messages you can get information about the quality of the media, round trip time and packet loss. You can also craft messages to influence the media quality.

Instructions

Download rtcp-processing

export GO111MODULE=on
go get github.com/renlforreal/webrtc/v3/examples/rtcp-processing

2. Run rtcp-processing < my_file

Input rtcp-processing's Session Description into your browser

Copy the text that rtcp-processing just emitted and copy into the second text area in the jsfiddle

Hit 'Start Session' in jsfiddle

You will see console messages for each inbound RTCP message from the remote peer.

Congrats, you have used Pion WebRTC! Now start building something cool
