Description

``I am not getting the core multi audio code where it is showing multi audio.
Current vidojs is showing multi audio based on language i worked in local code to change it to show using id.
because of in case language is undefined it show only one audio .
But in the source code i didnt get the code to that .
any one know please help me.

var organizeAudioPlaylists = function organizeAudioPlaylists(
    playlists,
    sidxMapping
  ) {
    if (sidxMapping === void 0) {
      sidxMapping = {};
    }
 
    var mainPlaylist;
    var formattedPlaylists = playlists.reduce(function (a, playlist) {
      var role =
        (playlist.attributes.role && playlist.attributes.role.value) || "";
 
      console.log("playlist.attributes.lang", playlist.attributes.lang);
      var language =
        playlist.attributes.lang == undefined
          ? playlist.attributes.lang
          : playlist.attributes.lang || "";
      var label = "main";
 
      if (language) {
        var label2 =
          playlist.attributes.lang == undefined
            ? playlist.attributes.id
            : playlist.attributes.lang || "";
        var label = "main";
        var roleLabel = role ? " (" + role + ")" : "";
        label = "" + label2 + roleLabel;
      } // skip if we already have the highest quality audio for a language
 
      if (
        a[label] &&
        a[label].playlists[0].attributes.BANDWIDTH >
          playlist.attributes.bandwidth
      ) {
        return a;
      }
 
      a[label] = {
        language: language,
        autoselect: true,
        default: role === "main",
        playlists: addSegmentInfoFromSidx(
          [formatAudioPlaylist(playlist)],
          sidxMapping
        ),
        uri: "",
      };
 
      if (typeof mainPlaylist === "undefined" && role === "main") {
        mainPlaylist = playlist;
        mainPlaylist["default"] = true;
      }
 
      return a;
    }, {}); // if no playlists have role "main", mark the first as main
 
    if (!mainPlaylist) {
      var firstLabel = Object.keys(formattedPlaylists)[0];
      formattedPlaylists[firstLabel]["default"] = true;
    }
 
    return formattedPlaylists;
  };

Thanks @mister-ben plz help me with below also

how can i merge changes done here to the videojs .
how it get reflect there , where i wwant to include this plugin or what.

@Prathik9 the mpd-parser is a dependency of videojs and VHS (the MSE video playback engine behind video.js' mpeg-DASH support). See the package.json.

I think this belongs in the mpd-parser so I moved it. We could potentially handle cases of lang being undefined a bit better, marking as an enhancement.

insted of language if we use id it shows in the ui otherwise , even the stream contain multi audio if its lack in laguage it shows single audio
