That one sounds like the most doable ;-)

Our experiences with a gstreamer-vaapi+libva-vdpau-driver+r600/radeon si on Radeon GPU are pretty good.

First check if your vdpau implementation is there with

vdpauinfo

If this does not  show reasonable output your Radeon driver is missing something. Which distro? With 
ubuntu there where was some trouble for 14.04:

If it does, check your libva-vdpau-driver:

vainfo

If this is not working re-check your libva-vdpau-driver installation. If this is fine make sure you 
have gstreamer-vaapi stuff installed:

gst-inspect-1.0 vaapi

Most of this should be there in ubuntu based distro as packages (except the mesa story above).
