TREAMING__ Audio Streaming protocol for audio stream transmission Centralized protocol

. HTTP Live Streaming

HTTP Live streaming is an HTTP-based streaming media transport protocol proposed by Apple. It cuts an entire audio and video stream into a small audio and video stream that can be downloaded by HTTP and generates a playlist (m3u8), where the client only needs to get a m3u8 playlist of resources to play the audio and video. Can realize live broadcast and on-demand. HLS is the technology to achieve live broadcast on demand, its delay will always be higher than the ordinary streaming media live protocol.

The following technical key points need to be studied and implemented

Data acquisition of video source and audio source

H264 encoding and AAC coding of raw data

Video and audio data encapsulated as Mpeg-ts packages

HLS segmentation Generation Strategy and m3u8 index file

HTTP Transport Protocol

Browsers that support HTML5

2.RTMP (Real time messaging Protocol (live Messaging protocol))

Based on TCP/IP protocol, browsers that support Flash products, browsers that support HTML5 (file playback is good, live live support is poor)

3.rtsp/trcp/rtp

Support player based on UDP protocol

Video data transmitted by RTP protocol

Video quality controlled by RTCP

Video control provided by RTSP (for example, forward, back, paused, etc.)
