In "Let WEBRTC support H264 codec" I provide a priority to use the H264 codec thinking. We can verify it on the browser side. There are three ways to verify: In JS print SDP view Chrome's log chrome_debug.log (see Open Chrome Log) Grab bag using webrtc-internals The first three kinds are no longer introduced, we look at the webrtc-internals. The WEBRTC status information in the current browser can be see

The project uses video codec, which has been around for the last half a month. To be honest, it has taken a lot of detours and wasted a lot of time.
