<Video source={"background"}    // Can be a URL or a local file

       rate={1.0}               // 0 is paused, 1 is normal.

       volume={1}               // 0 is muted, 1 is normal.

       muted={false}            // Mutes the audio entirely.

       paused={false}           // Pauses playback entirely.

       repeat={true}            // Repeat forever

       style={styles.backgroundVideo} />

// Later on in your styles..
