On the video playback server, the backend transmits the video address to the front end.

How did you write the header and output the video content cyclically?

The backend transmits the video address to the front end. html5 supports video playback. use tags.

Is it the HLS protocol?
This kind of thing should first look at the network protocol, find information, or which CDN video stream you use will also write the corresponding protocol
