Original commit message from CVS: Based on a patch by: Sonicadvance1 at GMAIL dot COM * ext/timidity/gstwildmidi.c: (gst_wildmidi_init), (gst_wildmidi_change_state), (plugin_init): * ext/timidity/gstwildmidi.h: Initialize wildmidi only once in the plugin init function instead of once for every instance. The second and following calls to the wildmidi initialization function will fail. Fixes bug #525613. Also don't register the element at all if wildmidi initialization fails.

* Wrapper element for libtimidity. This element works in pull
|
|
* based mode because that's essentially how libwildmidi works.
|
|
* We create a libwildmidi stream that operates on the srcpad.
|
|
* The sinkpad is in pull mode.
