Displaying Closed Captions
Displaying Closed Captions
I have MS's github sample for Windows Universal VideoPlayback working to display OTA TV from a Quatro. I'm now trying to get closed captioning working. When using the sample's mkv video file as a source with the "in band" example, the player does display captions. However, when using the Quatro's stream as the source I'm not seeing the loading of captions being triggered. Are captions embedded in the stream or by chance need to be loaded from a separate resource?
Re: Displaying Closed Captions
In the US OTA closed captions are embedded in the video stream itself. The standard is called CEA-608/708. Not all video decoding and subtitle libraries support embedded closed captions; you may want to check your video player to ensure captions embedded in the video stream are supported.
Re: Displaying Closed Captions
Microsoft's UWP MediaPlayerElement player doesn't seem to support embedded CEA-708 closed captions. Captions are also not presented as an option even within Microsoft's Movies & TV store app when playing an HDHomeRun channel (Movies & TV app / Personal / Media servers / HDHomeRun DMS / Channels / select channel).
@nickk, care to share the solution the HDHR Win10 app is using to display captions? using a 3rd party player or...?

Re: Displaying Closed Captions
We wrote a CEA 608/708 stack (as well as a DVB subtitles stack) for the HDHomeRun app.

No claiming credit for DVB subtitle support until you actually release an app that includes it.
