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

boolean onEncodedVideoFrameReceived(ByteBuffer buffer, EncodedVideoFrameInfo info);

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
