Background information

In Real-Time Communication scenarios, you can set video encoding properties to adjust video definition and smoothness. For one-to-one video calls, you can increase the resolution and frame rate for a better user experience. If multiple users are in a channel, you can lower the resolution and bitrate to reduce resource consumption and downstream bandwidth usage.

Implementation

Before setting video properties, call the getAvailableResolutions method and pass the camera parameter to retrieve the supported resolutions and frame rates. Then, call the setVideoProfile method to set the video properties. The settings take effect after you call publish.

aliWebrtc.setVideoProfile({ 
      width,
      height,
      frameRate,
    },type);
