VideoEncodedFrameObserver

Receives encoded video images.

onEncodedVideoFrameReceived

Reports that the receiver has received the to-be-decoded video frame sent by the remote end.

final void Function(int uid, Uint8List imageBuffer, int length,
      EncodedVideoFrameInfo videoEncodedFrameInfo)? onEncodedVideoFrameReceived;

If you call the setRemoteVideoSubscriptionOptions method and set encodedFrameOnly to true, the SDK triggers this callback locally to report the received encoded video frame information.

Parameters

uid: The user ID of the remote user.
imageBuffer: The encoded video image buffer.
length: The data length of the video image.
videoEncodedFrameInfo: For the information of the encoded video frame, see EncodedVideoFrameInfo.
