read / write

Occurs when the camera is turned on and ready to capture video.

Deprecated Use LocalVideoStreamState.Capturing in the RtcEngineEventHandler.localVideoStateChanged callback instead. If the camera fails to turn on, fix the error reported in the LocalVideoStreamState.Failed callback. The EmptyCallback typedef does not include any parameter.
