onPlayerVideoSizeChanged property

(void Function(String streamID, int width, int height)?) onPlayerVideoSizeChanged
getter/setter pair

The callback triggered when the stream playback resolution changes.

Available since: 1.1.0 Description: After the startPlayingStream function is called successfully, the play resolution will change when the first frame of video data is received, or when the publisher changes the encoding resolution by calling setVideoConfig, or when the network traffic control strategies work. Use cases: Developers can update or switch the UI components that actually play the stream based on the final resolution of the stream. Trigger: After the startPlayingStream function is called successfully, this callback is triggered when the video resolution changes while playing the stream. Caution:

  1. If the stream is only audio data, the callback will not be triggered.
  2. If the user enables custom video rendering of the ZegoVideoBufferTypeEncodedData type, the SDK is not responsible for video decoding and will not trigger this callback. Note: This function is only available in ZegoExpressVideo SDK!
  • streamID Stream ID.
  • width Video decoding resolution width.
