Except if the hardware fails to decode the provided video (but would succeed for
the codec in principle).

Please try (in the ffmpeg build directory):
./ffmpeg -i tests/data/a-dv50.dv -s 784x576 -vcodec libx264 test.mp4
mplayer test.mp4 -vc ffh264vdpau
(Dont' forget to set the terminal's history to a large value)
