Weird, but when I list the encoders via: ./ffmpeg -encoders
(where ffmpeg is in cinelerra's subdirectory of
thirdparty/ffmpeg-6.1) qsv is not listed that I can see.
well, it requires intel's media SDK .... try to look at gentoo
forum link I found, it lists package names.
My FFmpeg 6.0.1 (not the latest 6.1) on Tumbleweed-Slowroll has
currently only AV1 QSV Decoder (no encoder):
ffmpeg -codecs -hide_banner | grep av1
DEV.L. av1 Alliance for Open Media AV1
(decoders: libdav1d libaom-av1 av1 av1_cuvid av1_qsv )
(encoders: libaom-av1 librav1e libsvtav1 av1_nvenc av1_amf )
DEAIL. wmav1 Windows Media Audio 1
_Notice_:
All Intel GPU media users are encouraged to switch to VPL to take
advantage of hardware capabilities as soon as they become available.
The switch to VPL from Media SDK in FFMPEG, is simple. Just
substitute ‘--enable-libvpl’ instead of ‘--enable-libmfx’

oh, update treadmill running again!
Anyway for AV1 on A380 I found this post:
https://forum.jellyfin.org/t-arc-a380-qsv-hwa?page=2
it was working at the end but was picky about configuration options
...... in september 2023 or so.
so, you can't be sure it works just because wiki lists it as supported :(
Yes, I think we may be in some early stage while things mature.
To another Jelly user question about Vaapi vs QSync - performance
difference, it was estimated that QSV can be 10~20% faster than VAAPI
https://www.reddit.com/r/jellyfin/comments/y7k70s/vaapi_vs_qsync_performance_difference/?rdt=62899
Warning, not sure how well qsv can co-exist with vaapi on any
given (not so new) hw configuration, so watch out for installing
files (may be rpm/deb package will warn if something about to be
overwritten?)

I am wondering if the news and enhancements of
importance to
CinGG/FFmpeg 6.1 users may be outlined, including
what is ready now and
expected upcoming next?
Although not exactly as requested, I have updated
November News to better outline what *CinGG *takes
advantage**of in the 6.1 version of ffmpeg. If you can
think of anything I left out as it pertains to
Cinelerra, please email that. A lot of the new features
are only really relevant on the command line and these
are best outlined in many places on the internet
already. In addition I have minimally tested new
formats of WBMP and HDR and have the ffmpeg/video
directory format files ready for GIT checkin.
I have tried testing AV1 capability with little success
yet, but will continue to see if I can get an updated
dav1d library version update for newer operating systems.
**https://www.cinelerra-gg.org/news-updates/november-2023-release-and-build-farm-announcement/
Thank you.
Re: 5, only "NVIDIA NVENC AV1 encoding support" seems to
be mentioned.
What about Intel (Arc) AV1 QSV and AMD AMF encoders in
FFmpeg?
