In comment 2 of that bug is was agreed to set the id to the tuple ("Period@id","AdaptationSet@id"[,"ContentComponent@id"]). This change didn't make it into the PR that closed bug 26921. This change still needs to be done.

Why can't the HTML track id be the media resource track id? Seems like only one Period is active at a time and media resources require track ids to be unique.
