Chromecast does not display captions using segmented webvtt in HLS stream #498

What steps will reproduce the problem?
I am using a custom receiver app and trying to play a HLS stream with segmented 
webvtt.
I have got CORS support setup going and stream works fine, however subtitles do 
not show up.

HLS stream with segmented webvtt :

-subtitles.com.edgesuite.net/11/116/index.m3u8~lang=en

Subtitles appear fine on iOS, AppleTV, and QuickTime Player on Safari browser.
If you download the m3u8 playlist, you would see that English subtitles is part 
of the master playlist.
However it does not show as one of the stream by the Media player library.
window.player.getStreamingProtocol ().getStreamCount () = 1 which is just the 
video stream.

What is the expected output? What do you see instead?
English Subtitles should appear and media player library should recognize 
subtitles as part of the stream.

What version of the product are you using? On what operating system?
Receiver app v2.0.0
Media Player Library v1.0

Please provide any additional information below.
Attached is the .m3u8 file for the HLS stream.

The #EXTM3U and #EXT-X-MEDIA tags in the master playlist are separated only by 
'\r'. This makes MPL parser not split the line when it parses the playlist.  
Please be sure that the line separator includes a newline character '\n'.
