           Summary: Unable to set language tags
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: Uraeus at linuxrising.org

     GNOME version: ---


I am trying to set the language tag for Ogg or Quicktime files, but it doesn't
seem to work. I do know the tagsetting code works because the 'Transmageddon
transcoder' tag does get set in Quicktime. But language or language-code seems
completely unaffected by my attempts.

           tagyes = factory.has_interface("GstTagSetter")
           if tagyes ==True:
               taglist=Gst.TagList.new_empty()
               taglist.add_value(Gst.TagMergeMode.APPEND,
Gst.TAG_APPLICATION_NAME, "Transmageddon transcoder")
               if self.audiodata[0]['languagecode'] != None:
                       taglist.add_value(Gst.TagMergeMode.APPEND,
Gst.TAG_LANGUAGE_CODE, self.audiodata[0]['languagecode'])  # FIXME: Currently
only doing 1 stream
                       taglist.add_value(Gst.TagMergeMode.APPEND,
Gst.TAG_LANGUAGE_NAME, self.audiodata[0]['language'])
                       print(taglist.to_string())
               element.merge_tags(taglist, Gst.TagMergeMode.REPLACE)
