setupLocalVideo abstract method

Future<void> setupLocalVideo(VideoCanvas canvas)

Initializes the local video view.

This method initializes the video view of a local stream on the local device. It affects only the video view that the local user sees, not the published local video stream. Call this method to bind the local video stream to a video view (view) and to set the rendering and mirror modes of the video view. After initialization, call this method to set the local video and then join the channel. The local video still binds to the view after you leave the channel. To unbind the local video from the view, set the view parameter as NULL. In real-time interactive scenarios, if you need to simultaneously view multiple preview frames in the local video preview, and each frame is at a different observation position along the video link, you can repeatedly call this method to set different view s and set different observation positions for each view. For example, by setting the video source to the camera and then configuring two view s with position setting to positionPostCapturerOrigin and positionPostCapturer, you can simultaneously preview the raw, unprocessed video frame and the video frame that has undergone preprocessing (image enhancement effects, virtual background, watermark) in the local video preview. You can call this method either before or after joining a channel. To update the rendering or mirror mode of the local video view during a call, use the setLocalRenderMode method.

• canvas The local video view and settings. See VideoCanvas.

Returns When the method call succeeds, there is no return value; when fails, the AgoraRtcException exception is thrown. You need to catch the exception and handle it accordingly. < 0: Failure.
