webrtc-camera-viewer

Show a live view of a v4l2 camera remotely with low latency using WebRTC.

Basic overview

Gstreamer sets the video properties, encodes to H.264 using the hardware encoder, and sends RTP packets via UDP to localhost.

Pion WebRTC consumes the RTP stream and sends it to a WebRTC client.

The webpage runs the WebRTC client and shows the live view of the camera.

Hardware: Radxa Zero 3W (RK3566)
