Wechat video account cooperates with OBS to pull stream and push stream to open live broadcast

background

The company has a requirement to realize the simultaneous live broadcast of external video streams, so I deliberately studied the operation steps of OBS software combined with WeChat video account live broadcast.

1. OBS software configuration

(1) Configuration pull flow

1. Start the OBS software - click "+" - choose to add "media source"
   

2. create source name
   

3. Cancel the local file - fill in the streaming address - modify the network buffer to 5MB (recommended)
   

4. Test whether the pull flow is normal

   The streaming address and streaming key come from the live broadcast settings of the WeChat video account

3. Click "Video" - base (canvas) resolution 1920X1080 - output (scaled) resolution 1280X720.
   
4. Click "Start streaming" to start live streaming to the WeChat video account.
