fixes a memory leak

(In reply to comment #43)

> > I made some tests: I applied my patch. Then I asked gstreamer for some planar yuv format, and performed the conversion on the shader. With a few videos on a page, GtkLauncher seemed less responsive with accelerated compositing than without. So unless, there is a better way to achieve that, it seems like it decreases performance. I do not have numbers to back that claim though.

There was indeed a problem with the patch. It did not unref the gstreamer buffer properly, and a lot of memory leaked. Here is an updated patch. With it, there is no noticeable difference between requesting xrgb or yuv format.
