[Bug 755072] vaapi: expose memory:DMABuf capsfeature

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=755072

--- Comment #48 from Julien Isorce <julien.isorce at gmail.com> ---
I implemented options 2, i.e. re-use GstVaapiSurface->extbuf_proxy to cache
GstVaapiBufferProxy which now owns the GstMemory(FD). And seems to work fine, I
can see that in GstGL it creates only 16 EGLImages (2 per frames and because 8
dmabuf because 8 vaapisurface on a 720p video) but then that is all, it is
cached and properly re-used in GstGL.

(branch "ceyusa_755072_plus_caching")

I had to add the 3 new following API:

GstMemory*
gst_vaapi_buffer_proxy_get_memory (GstVaapiBufferProxy * proxy, gsize size);

void
gst_vaapi_surface_set_buffer_proxy (GstVaapiSurface * surface,
    GstVaapiBufferProxy * proxy);

GstVaapiBufferProxy *
gst_vaapi_surface_peek_buffer_proxy (GstVaapiSurface * surface);

Let's discuss about it and then I can re-work it.
