/**
 * @param scaleToFit Whether video frames should be scaled to fit when rendering.
 * @param allowedJoiningTimeMs The maximum duration in milliseconds for which this video renderer
 *     can attempt to seamlessly join an ongoing playback.
 * @param eventHandler A handler to use when delivering events to {@code eventListener}. May be
 *     null if delivery of events is not required.
 * @param eventListener A listener of events. May be null if delivery of events is not required.
 * @param maxDroppedFramesToNotify The maximum number of frames that can be dropped between
 *     invocations of {@link VideoRendererEventListener#onDroppedFrames(int, long)}.
 * @param drmSessionManager For use with encrypted media. May be null if support for encrypted
 *     media is not required.
 * @param playClearSamplesWithoutKeys Encrypted media may contain clear (un-encrypted) regions.
 *     For example a media file may start with a short clear region so as to allow playback to
 *     begin in parallel with key acquisition. This parameter specifies whether the renderer is
 *     permitted to play clear regions of encrypted media files before {@code drmSessionManager}
 *     has obtained the keys necessary to decrypt encrypted regions of the media.
