Streaming video data, how to synchronize clients?

Question

Video broadcast

You need to write a program that will simultaneously display data from the server on several clients. Since the program will be more likely to play video and audio, it is necessary that the data transfer be as efficient as possible. I will use the UDP protocol for transmission, the question is: what are the methods for synchronizing packets on the network? Or methods for synchronizing the clients themselves?

Answer 1

Do you really need very accurate video synchronization?
If the player's buffer size is 0.1s and delivery via udp is acceptable, then it seems that the video will not be able to physically desynchronize by more than these same 0.1s, which is indistinguishable at a glance..
