#### source

Sets the media source. You can pass an asset loaded via require or an object with a uri.

The docs for this prop are incomplete and will be updated as each option is investigated and tested.

##### Asset loaded via require

Example: 

```

const sintel = require('./sintel.mp4');

source={sintel}

```

##### URI string

A number of URI schemes are supported by passing an object with a `uri` attribute.

###### Web address (http://, https://)

Example:

```

source={ uri: 'https://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_10mb.mp4' }

```

Platforms: all

###### File path (file://)

Example:

```

source={ uri: 'file:///sdcard/Movies/sintel.mp4' }

```

Note: Your app will need to request permission to read external storage if you're accessing a file outside your app.

Platforms: Android ExoPlayer, Android MediaPlayer, possibly others

###### iPod Library (ipod-library://)

Path to a sound file in your iTunes library. Typically shared from iTunes to your app.

Example:

```
