Sets the Android.Views.Surface to be used as the sink for the video portion of the media. This is similar to MediaPlayer.SetDisplay(Android.Views.ISurfaceHolder), but does not support MediaPlayer.SetScreenOnWhilePlaying(bool). Setting a Surface will un-set any Surface or SurfaceHolder that was previously set. A null surface will result in only the audio track being played. If the Surface sends frames to a Android.Graphics.SurfaceTexture, the timestamps returned from Android.Graphics.SurfaceTexture.Timestamp will have an unspecified zero point. These timestamps cannot be directly compared between different media sources, different instances of the same media source, or multiple runs of the same program. The timestamp is normally monotonically increasing and is unaffected by time-of-day adjustments, but it is reset when the position is set.
