The camera itself is a server that can

This paper mainly introduces the RTP/RTCP protocol in WEBRTC, Weizhenwei, the earliest published articles in the Wind network, ID:BEFOIOSupport original, reprint must indicate the source, welcome attention to my public number blacker (Id:blackerteam or WEBRTCORGCN).a prefaceThe RTP/RTCP protocol is the cornerstone of streaming media communications. The RTP protocol defines the packet format for

WEBRTC source code, the transmission and reception of video packets is taken as an example, and the implementation of Anck packet retransmission mechanism is deeply analyzed. The main contents include: SDP negotiation Nack, receiving end packet loss determination, NACK message construction, sending, receiving and parsing, RTP packet retransmission. The following are discussed in detail.I. SDP negotiation N

Switch from using WEBRTC to build front-end video chat room--Data channel ChapterIn two browsers, it is very complex to send messages for chat, games, or file transfers. Usually, we need to set up a server to forward the data, of course, the larger the size of the case, will be expanded into multiple data centers. In this case, there is a high latency and it is difficult to guarantee the privacy of the data
