FEM 2175 - Add Captions styling to ExoPlayerWrapper

[GouravSna]

Create SubtitlesStyle using,

SubtitleStyleSettings subtitleStyleSettings = new SubtitleStyleSettings("NormalStyle")
                    .setSubtitleBackgroundColor(Color.BLUE)
                    .setSubtitleTextColor(Color.WHITE)
 .setSubtitleTextSizeFraction(SubtitleStyleSettings.SubtitleTextSizeFraction.SUBTITLE_FRACTION_50)
                    .setSubtitleWindowColor(Color.YELLOW)
                    .setSubtitleEdgeColor(Color.BLUE)
                    .setSubtitleTypeface(SubtitleStyleSettings.SubtitleStyleTypeface.MONOSPACE)
     .setSubtitleEdgeType(SubtitleStyleSettings.SubtitleStyleEdgeType.EDGE_TYPE_DROP_SHADOW);

Attributes are:

• Background Color
• Text color
• Text Size
• Window Color
• Edge Color
• Font family
• Edge type

Then set the subtitleStyleSettings in PlayerSettings,

player.getSettings().setSubtitleStyle(subtitleStyleSettings);

To update the subtitles create another object using the above method and then call updateSubtitleStyle(..) on player object ,

player.updateSubtitleStyle(subtitleStyleSettings);

Except the the minor comment, looks good now. But don't merge yet.

• add parsable so application(or Kaltura player) can save user settings and apply them on each player instantiation.
• Shorten builder set/get names and omit subtitles, e,g. setSubtitleBackgroundColor ==> setBackgroundColor
