UWP MediaElement Closed Caption Support

I'm writing an Windows 10 UWP app (NOT WPF or Sliverlight) which can play media files.

To do so, I am using MediaElement Class to implement a player.

The problem is that I cannot find what kinds of caption are supported by MediaElement(ME). I could not find any website that explains it.

Is there any web page that has information about exact scope of internal/external captions that ME supports?

My Attempts

To know internal closed caption support, I tried playing some .mkv files that include various closed captions. The result is here:

  1. Works well: UTF-8 Plain Text, ASS Format
  2. Doesn't work: VobSub, Timed Text(Codec ID:tx3g), PGS

Also, for external closed caption files (.srt, .ass, .smi for example), I could check that .srt files are supported by using TimedTextSource but .smi files are not. (From VideoPlayback project in windows-universal-samples)

I wish there exists a page about this information.

Thanks in advance :)

Have you seen the Microsoft VideoPlayer sample? – Rowland Shaw
Yes, this is same project that I have tried for external CC (above 'VideoPlayback project in windows-universal-samples'), but thank you for your kindness :) – Hyundo Moon

you can use Microsoft Media Player Framework I think is the most complete media player for UWP apps supports advanced scenarios and obviously supports closed captions and the best thing is open source.

You can use TimedTextSource to support closed-captioning. See Scenario 4 in Microsoft's VideoPlayback sample. You have to set the TimedTextSource as an ExternalTimedTextSources in the MediaSource.
