onSEIStreamUpdate property

OnSEIStreamUpdateType? onSEIStreamUpdate

Callback about publishing status of the black frame video stream.

In a voice call scenario, when the local user calls RTCVideo.sendSEIMessage to send SEI data with a black frame, the sending status of the stream is notified to the remote user through this callback.
You can tell from this callback that the video frame carrying SEI data is a black frame and thus not render that video frame.

Implementation

OnSEIStreamUpdateType? onSEIStreamUpdate;
