调研方向

Start by locating organizeAudioPlaylists in the source corresponding to the dist code shown. Compare how audio playlists are grouped when the manifest language is undefined and verify the behavior with the reporter's local multi-audio case. Done means distinct audio tracks are available in the UI without relying on a language value.

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;
  };

if i use .id insted of .lang it show multi audio option in ui even though language is undefined in manifest.
i found this in dist folder of videojs whre can i find these in source code
