MultiDataSource

Multi data source supports fetching assets from multiple URI schemes. If the data source is an HTTP/HTTPS source, then it will check the offline store to check if the asset has been downloaded already and automatically convert to DataSpec to point to local copy of the asset.

The supported schemes are:

• file: For fetching data from a local file (e.g. file:///path/to/media/media.mp4, or just /path/to/media/media.mp4 because the implementation assumes that a URI without a scheme is a local file URI).
• asset: For fetching data from an asset in the application's apk (e.g. asset:///media.mp4).
• content: For fetching data from a content URI (e.g. content://authority/path/123).
• rtmp: For fetching data over RTMP. Only supported if the project using ExoPlayer has an explicit dependency on ExoPlayer's RTMP extension.
• http(s): For fetching data over HTTP and HTTPS (e.g. https://www.something.com/media.mp4).
