--- Comment #5 from Fabrice Bellet <fabrice at bellet.info> ---
On a thinkpad X220 (Intel HD Graphics 3000), running the latest packages of the
upcoming Fedora 21, updates-testing repo enabled, with gstreamer1-vaapi
installed, and libva-intel-driver from rpmfusion :

(same pipeline works fine on another Fedora-21 box, with an AMD card, and the
vdpau vaapi driver.)
