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.

Encoding and decoding, or the conversion of data from one specific protocol format to another format. These tasks are handled by components that are commonly referred to as codecs. Netty provides a variety of components that simplify the process of creating a custom codec to support a wide range of protocols. For example, if you are building a Netty-based mail server, you will find that Netty's support for codecs is invaluable for implementing POP3, I
