           Summary: vorbisidec conflicts with vorbisdec
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: lrn1986 at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


When both vorbis and tremor plugins are installed, i get this when building the
documentation (i assume this will also come up every time gstreamer-based
application runs):

(gst-plugins-base-libs-scan.exe:3452): GLib-GObject-WARNING **: cannot register
existing type `GstVorbisDec'
(gst-plugins-base-libs-scan.exe:3452): GLib-CRITICAL **: g_once_init_leave:
assertion `result != 0' failed
(gst-plugins-base-libs-scan.exe:3452): GStreamer-CRITICAL **:
gst_element_register: assertion `g_type_is_a (type, GST_TYPE_ELEMENT)' failed

The reason is that both tremor and vorbis plugins share GstVorbisDec class, and
both will try to register it in its plugin_init() function when calling
gst_vorbis_dec_get_type().

It will probably be necessary to give tremor a separate class (it might share
the implementation with GstVorbisDec, but it must still be separate from it, at
least as far as GObject is concerned).

Since simultaneous use of tremor and vorbis is non-trivial and makes little
sense (to me), i'm giving this a "minor" severity.
