 * Which media stream of a call a playback or recording operation targets.

 * A call carries two independent outgoing video streams: the main camera stream (transmitted
 * alongside the microphone audio) and a separate presentation (screen-sharing) stream. The playlist
 * controls ({@see Call::play()} and friends) take one of these to say which stream they act on; it
 * defaults to {@see self::Camera}. Recordings ({@see Call::setOutput()}) pick their streams with {@see CallStream} flags instead.
