@cnSchwarzer what you think? The official display supports linux. Why add it?

vcpkg/ports/mfx-dispatch/vcpkg.json

Line 8 in 185a7aa

"supports": "!linux & !uwp & !osx",

Oops, I will add it now.

[reitowo]

I reminded that I didn't ever test for linux, so I disabled linux support.

I build and install success Intel Media Driver and intel mediaSDK with out install mfx-dispatch ,
i think ,ffmpeg[qsv] don't need depend mfx-dispatch.
i guess mfx-dispath only need on windows?

[reitowo]

Not sure, I added it anyway.

[chuckypt]

i edit ffmpeg/vcpkg.json
before
"qsv": {
"description": "Intel QSV Codec",
"dependencies": [
"mfx-dispatch"
]
},
after:
"qsv": {
"description": "Intel QSV Codec"
},

finish build success!
