Playing MKV does not use iGPU, CPU instead

Hello guys,

​

After some trail and error, I managed to fix the "Could not allocate error" and enabled my iGPU.

VideoProc tells me my Intel HD 630 supports H264 and HEVC.

Playing jellyfish-70-mbps-hd-hevc.mkv with mpv spins up my CPU...

Why does MPV use my CPU to play the video, and don't use my iGPU? I have an eGPU, RX570 who works.

I am using Opencore with the following settings:

​

<key>PciRoot(0x0)/Pci(0x2,0x0)</key> <dict> <key>AAPL,ig-platform-id</key> <data>AwCRPg==</data> <key>framebuffer-patch-enable</key> <data>AQAAAA==</data> <key>device-id</key> <data>kj4AAA==</data> </dict> 

Thanks.
