Commit c2b89d62 by andrewlewis Committed by Oliver Woodman
Options

Add SampleSourceProvider as a factory for SampleSources (playlists #2). 

Initially only the first source index is used. In a later change,
ExoPlayerImplInternal will create SampleSources for different playlist item
indices as necessary.
