lack of the flags answering for --enable-libmfx --enable-memalign-hack Also there is no library for satisfaction of dependences of this (mfx library https://git.videolan.org/?p=mfx_dispatch.git)
Intel Quick Sync Video is available since 2011, it's time to support it in Gentoo
I believe we also would need to have Intel Media Server Studio in portage as a dependency for --enable-libmfx
QSV support is a true nightmare: https://blogs.gentoo.org/lu_zero/2016/10/31/intel-mediasdk-mini-walkthrough/ - Requires outdated and heavy patched libraries. - Requires outdated kernel in order to apply all required patches. (lu_zero is also the mfx_dispacth's mantainer https://github.com/lu-zero/mfx_dispatch) Intel doesn't provide any kind of support on mediasdk community support. VA-API works fine and offers the same performance level. ciao luigi
(In reply to Luigi 'Comio' Mantellini from comment #3) > QSV support is a true nightmare: > Perhaps for the full support of the tools one needs Intel Media Server Studio, but for ffmpeg it says otherwise. "FFmpeg QSV support relies on libmfx" and then "Requriments on Linux: ... or use a recent enough supported system, with the libva and libdrm libraries, the libva Intel drivers, and the libmfx library packaged by lu_zero." see here: https://trac.ffmpeg.org/wiki/HWAccelIntro#IntelQSV Therefore adding it to Gentoo should be as easy as adding libmfx library and --enable-libmfx flag to ffmpeg.

I used QSV as use flag as it seemed more appropriate than less understandable MFX. BTW I was unable to find licence specific for Intel and BSD3 therefore added new one under name BSD-3-Intel in the mfx-dispatch ebuild taken from https://github.com/lu-zero/mfx_dispatch/raw/master/COPYING
Any particular reason why QSV has not been added to portage for new ffmpeg-3.3? You guys know it is mainly used for fast encoding not decoding right?

Full report is at > https://forums.gentoo.org/viewtopic-p-8184646.html > I actually tried to encode using quick sync, but I failed with the same error You have (more in the forum). I also failed with git version which also add several new Intel platforms (see new attachment), but maybe you or others will have more luck. I think bunder in the forum was right and it all comes down to whether all firmware on your platform works properly or not. Make use to check module options for your kernel version as their names change. In 4.17 it is "i915.enable_guc=2". You may also try "i915.enable_guc=-1" but it almost hanged my desktop, YMMV.
