[Francois Cartegnie]

vlc/vlc-1.1 | branch: master | Francois Cartegnie <fcvlcdev at free.fr> | Tue Dec  6 16:38:07 2011 +0100| [199e3d8adf2878354472c10de219bf00371e22ad] | committer: Jean-Baptiste Kempf

vaapi: fix profiles detection.

The selected profile wasn't checked against card's ones.
(ex: resulting in sending MPEG2 to a VC1/h264 only card)
