rtsp-bench is a WebRTC server that pulls from an RTSP feed, and then re-distributes via WebRTC. It generates a report.csv with the CPU Usage and connected PeerConnection count.
This repo contains a CLI WebRTC Client that will connect and perform the load test. This is done via a REST API hosted on :8080/doSignaling. You can also watch the video/load test via the web UI at :8080/,
it connects via the same REST API as the CLI.
This project heavily borrows from RTSPtoWebRTC. If you are looking for a full featured application to deploy that is probably a better choice. It is driven by a config file and has proper error handling.
export GO111MODULE=ongit clone https://github.com/pion/rtsp-bench.gitcd rtsp-bench/servergo run main.go
You can then access the Web UI at http://localhost:8080. This requires a browser that supports H264, this repo doesn't do any error handling around signaling failures.
You can also use the provided WebRTC CLI
cd rtsp-bench/clientgo run main.go localhost:8080
In the server folder you will have a reports.csv that looks like
timestamp, peerConnectionCount, cpuUsage

The following graph was generated from the results.csv that was generated by the server. The client was run from another EC2 instance in the same VPC.
The Y Axis is the CPU Usage, and the X Axis is the count of PeerConnections. This was run on a m4.2xlarge (Intel(R) Xeon(R) CPU E5-2686 v4 @ 2.30GHz)
H264 that is approximately 250 Kb/s. You can change that here

None, on purpose.
Pion by design allows the user to specify what they want. We are distributing a video feed that is already encoded, and has a very small keyframe-interval so these things don't help us.
When setting up the PeerConnection you have full control of the RTP/RTCP pipelines, so users can add TWCC/NACK/FEC in a way that works for them.
