Remark:

1. Encoder: Encoder pushs RTMP stream to SRS.
2. MediaSource: Supports any media source, ingesting by ffmpeg.
3. Ingester: Forks a ffmpeg(or other tools) to ingest as rtmp to SRS, please read Ingest.
4. Streamer: Remuxs other protocols to RTMP, please read Streamer.
5. EXEC: Like NGINX-RTMP, EXEC forks external tools for events, please read [ng-exec][v4_CN_NgExec].
6. SRTModule: A isolate module which run in hybrid model.

System Requirements

Supported operating systems and hardware:

• Linux, with x86, x86-64 or arm.
• Mac, with intel chip.
• Other OS, such as Windows, please use docker.
