onSendFirstLocalVideoFrame property

void Function(TRTCVideoStreamType streamType)? onSendFirstLocalVideoFrame
final

The First Local Video Frame Was Published

After you enter a room and call startLocalPreview or startScreenCapture to enable local video capturing (whichever happens first), the SDK will start video encoding and publish the local video data via its network module to the cloud.

It returns the onSendFirstLocalVideoFrame callback after publishing the first local video frame.

  • Parameters:
    • streamType(TRTCVideoStreamType):
      • Video stream type. The primary stream (Main) is usually used for camera images, and the substream (Sub) for screen sharing images.
