/**
* <p>QuirkSummary
* Bug Id: b/196039619
* Description: Quirk denotes that the encoder surface needs to be removed from repeating
* request before stop the encoder. Otherwise, the camera will fail if
* {@link MediaCodec} is stopped while frames are still being provided.
* In {@link Recorder}, {@link Recorder#getStreamState()} has to returns
* {@link VideoOutput.StreamState#INACTIVE} when the active recording is being
* stopped. {@link VideoCapture} monitors {@link VideoOutput#getStreamState()}
* and detach the surface from camera if it becomes
* {@link VideoOutput.StreamState#INACTIVE inactive}. So making the
* {@link Recorder} inactive in stopping state will stop the camera from
* producing frames to the {@link MediaCodec} before actually stopping it.
* Device(s): All API 21 and 22 devices
