 ## Use
 1. Start the service: execute the livego binary file or `make run` to start the livego service;
-2. Get a channelkey from `http://localhost:8090/control/get?room=movie` and copy data like your channelkey.
-3. Upstream push: Push the video stream to `rtmp://localhost:1935/{appname}/{channelkey}` through the` RTMP` protocol(default appname is `live`), for example, use `ffmpeg -re -i demo.flv -c copy -f flv rtmp://localhost:1935/{appname}/{channelkey}` push;

-    - `RTMP`:`rtmp://localhost:1935/{appname}/{channelkey}`
-    - `FLV`:`http://127.0.0.1:7001/{appname}/{channelkey}.flv`
