/**
* Quirk denotes that the encoder surface needs to be removed from repeating request before stop
* the encoder.
*
* <p>As described in b/196039619, the camera fails if {@link MediaCodec} is stopped while frames
* are still being provided.
*
* <p>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.
