Sample: SA00040 SA10143 ism
SA00050 SA20021
SA10091 ilaced_twomv
Without patch:
Polaris 11 VDPAU p p p p* p p* p
VAAPI p p p f p f p
Skylake GT2 VAAPI p p f n f n p
With patch:
Polaris 11 VDPAU p p p p* p p* p
VAAPI p p f f f f p
Skylake GT2 VAAPI p p p n p n p
p = passes the fate test
p* = fail (output looks sensible and matches hashes Carl posted elsewhere in
this thread)
f = fail (output produced but is totally incorrect)
n = fail (no output - fails to decode at all)
