Luna Service for media in LG webOS 3.0 TV App

Need to know what the below service does.

luna://com.webos.media service (Note: It's not available in Luna service documentation)

I'm looking for language change in Subtitle/Audio for a channel. Please guide me through this.

Please refer the below sample.

 webOS.service.request("luna://com.webos.media", {
    method:"selectTrack",
    parameters: { "type": "audio", "index": index, "mediaId": mediaId },
      onSuccess: function (result) {
        console.log("[succes] select audio track " + index);
      },
      onFailure: function (result) {
        console.log( "[fail][" + result.errorCode + "] " + result.errorText );
        }
 });

Please mention the other available methods for this API.
