vaapi accel does not work with nvidia
Issue generated from Tuleap's migration script. Originally submitted by: Philippe Gorley (pgorley)
VAAPI hardware acceleration does not work with an Nvidia card and falls back to software decoding every time. This means there is no video until about 10 seconds into the call.
Libva fails to open the VAAPI driver with -1 (unknown libva error). The driver name is null.
