Hello,

The file bug.c shows a problem with the current gst-ffmpeg. 

If the same instance of the plugin is asked to be initialised more that once,
instances after the first one do not register the elements properly and the
elements become not usable.

For example, if you call gst_update_registry (), is not possible to create
elements after the call since the plugin is asked to be initialised again and
does not register the elements.

Runing the attached case returns these values:

Creating element ffenc_mpeg2video->a222bf8
Creating element ffdec_mpeg2video->a225048
Creating element ffmux_dvd->a226000
calls gst_update_registry
Creating element ffenc_mpeg2video->0
Creating element ffdec_mpeg2video->0
Creating element ffmux_dvd->0

Changing the sample muxer, encoder and decoder for similar Ogg ones do work as
expected.

Attached to this report you have the file to show the issue and proposed patch
to fix it.
