VP9 HDR

[The_ShadowWw]

Hey,
I just "solved" a problem that I had with youtube and HDR
when I was trying to view 2160p60 HDR my frames started dropping, even 1440p60 HDR loses some frames,

I have a 2700x and a GTX 1080 with 16gb ram, I can surely run 4k HDR
I checked the tv had HDMI 2.0b, the GPU had 2.0b, checked if I have the correct cable, surefed the forums

 

and found out the problem is that the GTX 1080 those not have vp9 hardware decoding, thats odd, as I can view 2160p60 non HDR content perfectly,

turns out VP9 has profiles and VP9 profile 2 is responsible to deliver HDR video on youtube

ironocally a 1030 and a 1050 can deliver HDR hw acceleration on youtube,

regarding AMD systems I could only find a wikipedia source, and it those not list the VP9 versions https://en.wikipedia.org/wiki/Unified_Video_Decoder

 

hopes this helps people struggling with HRD on youtube
