Can't get Intel Quick Sync to work on Windows

weaverm commented 3 years ago

I have installed Windows 10 Home 64-bit (version 20H2, OS build 19042.804) on my iMac via Boot Camp. This machine has a Core i5-7600K CPU and a Radeon Pro 580. I have statically linked ffmpeg 4.3.2-2021-02-27 (I've tried both the essentials and full release). When I try to do a --qsv or a --qsv --hevc I get an error.

[h264_qsv @ 000002ac1138b0c0] Error initializing an internal MFX session: unsupported (-3) [hevc_qsv @ 000002330a5ec380] Error initializing an internal MFX session: unsupported (-3)

If I do a --amf or --amf --hevc it works, but very slowly... 15 - 20 fps (with a 1080p blu-ray source mkv) and task manager says the CPU, GPU & disks are nearly idle.

I think I have this installed correctly and I think my Kaby Lake Intel CPU should do Quick Sync encoding. When running macOS 10.14.6 on this machine using Handbrake via Video Transcoding, Apple Video Toolbox does h.264 encodes using Quick Sync.

Surely I must have done something wrong?

I did find this issue: #16 with a similar error message, but on Ubuntu.

@weaverm You might need to add something like --qsv-device 1 to your command line. I've asked The HiveMind™ for other suggestions. Stay tuned...

weaverm commented 3 years ago

I tried --qsv-device 1 on the command line. No luck.

@weaverm Hmmmm, I'm starting to wonder if you have the correct drivers installed.

weaverm commented 3 years ago

I tried a different build of ffmpeg, but got the same failure. (from here: https://github.com/BtbN/FFmpeg-Builds/releases)

I wonder about drivers too. What drivers are we even talking about? I created this Boot Camp partition two days ago. I downloaded a Windows 10 Home retail ISO from Microsoft on the same day. MacOS created the partition and kicked off the Windows install from the downloaded ISO. Other than installing Steam, FireFox and Windows Updates, I haven't installed anything.

weaverm commented 3 years ago

There are no red Xs or exclamation marks in Device Manager that would indicate some piece of hardware isn't right.

lisamelton commented 3 years ago

@weaverm If you installed with an official retail version of Windows 10 Home then you probably have the drivers you need. So I have no idea what could be wrong at this point.

samhutchins commented 3 years ago

On my macbook pro, at least, bootcamp turns off the Intel GPU, and only exposes the AMD one. I would imagine it's the same on an iMac

lisamelton commented 3 years ago

@samhutchins Thanks for the information! That explains a LOT. It seems the QSV encoder is not accessible under Boot Camp. Sorry about that, @weaverm.

weaverm commented 3 years ago

I bet you're right. I don't recall seeing an Intel GPU in Device Manager, only the AMD one. Thanks for your help!
