Original commit message from CVS: * gst/mpegaudioparse/gstmpegaudioparse.c: (channel_mode_class), (GST_TYPE_MP3_CHANNEL_MODE), (mp3_type_frame_length_from_header), (gst_mp3parse_emit_frame), (mp3parse_get_query_types): * gst/mpegaudioparse/gstmpegaudioparse.h: Do an initial class_ref on an internal enum type from within the class_init function so that there aren't any issues when multiple mp3parse elements are started in separate threads at the same time. (Why we use an enum type here if the tag is registered as a string type, I don't know). Also remove custom UNUSED macro and use GLib's instead.
