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’

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.


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?
