Recognize streams marked as conforming to the "Constrained Baseline Profile". If VA driver supports that as is, fine. Otherwise, fallback to baseline, main or high profile. Constrained Baseline Profile conveys coding tools that are common to baseline profile and main profile. https://bugzilla.gnome.org/show_bug.cgi?id=719947 [Added fallbacks to main and high profiles] Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
