Is anyone running a 5700xt in there 5,1 running Catalina? Can anyone test 8k vp9 playback and report if you get smooth playback also also what the current cpu usage is. Neither my Vega vii nor Vega 64 support it and do not have a Navi card atm.
You have to enable HWAccel in order to make it workIs anyone running a 5700xt in there 5,1 running Catalina? Can anyone test 8k vp9 playback and report if you get smooth playback also also what the current cpu usage is. Neither my Vega vii nor Vega 64 support it and do not have a Navi card atm.
Did you read my post and the embedded video? My RX580 was doing the VP9 decode (8K Youtube). Without GPU decode, it's impossible to have that smooth playback on my single processor cMP.macOS has got no support for any VP9 hardware decoder, so that GPU will not help too much.
Thanks for the info. That's interesting, AFAIK, Polaris / Vega only has partial VP9 support, need CPU assist. That's why the CPU usage is high.No it's not. See your cpu usage. 600%. It would be something less than 10% is the actual GPU encoder was being used.
The only API di access hardware video acceleration on macOS is VideoToolbox. And VideoToolbox has got no VP9 support. Check the API on developer.apple.com is you don't believe me.
This is captured form that Wiki link. It looks like AMD added "some" VP9 support since UVD6.3. But only VCN1 has full VP9 support.Only Navi 10 and 14 and Raven have VP9 support according to this table:

Just want to make sure you selected 8K at here, right?8K 60fps VP9 videos via Chrome on my 5700XT under Catalina 10.15.3 - buttery smooth playback.

please verify, if you can. I’ve @attempted 8k playback under Mojave with Vega 64 and Vega vii, also I have a test SSD with Catalina 10.15.3, however both are only decoding via CPUs and stop to buffer every 5 sec. Have a similar configuration as your system. Was really hoping to see if anything was different under Catalina with navi. for some reason I thought the api was simply for safari and chrome or Firefox would bypass it. But my knowledge of how the framework works is beginner level at best. Still if AMD has cooked in vpn 8k24 Radeon multimedia engine does that mean the Catalina kext. (Driver) still has to used video toolbox APi to pass over to chrome or Firefox? both support hardware encoding last I checked. Well maybe my hope is dead till AV1 picks up...I believe 8K was selected. I’m not near my mac but will double check again.
12K VP9 New York video on YouTube also played smoothly with CPU usage at 54%

Safari definitely has no support for VP9.please verify, if you can.

The 7,1 CPU can handle that. So, hard to tell if your 7,1 decode those video by CPU / GPU.^^^^I'm on a NcMP 7,1. I can get 8K playback (Travelogs above) on Firefox, but not on Safari. Playback is smooth. GPU is an Aorus RX 5700 XT.
The problem is why w1z's 5,1 can do it with such low CPU demand. If not GPU, then what is it?
I am using RX580 , Play these YouTube 8K Video Smooth too.
