           Summary: [cdio] gst_element_make_from_uri hangs on "cdda://"
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: jrl at ids.org.au

The libcdio plugin (cddasrc) hangs when you try to create it with the uri
"cdda://". The cdparanoia plugin accepts this uri; I think it takes it to mean
"the entire cd", but I'm note sure. Totem uses this to query how many tracks are
on the CD.

To reproduce it:
a) have the libcdio plugin (cddasrc) installed
a) insert an audio cd
b) load totem and attempt to play the disc

When gst_element_make_from_uri is called with the uri "cdda://" it hangs, and
the following debug messages are produced (from debug level 5) repeatedly until
the program is killed.
