Andrew,
most likely our nv headers drifted from that ffmpeg-7.0/proprietary driver assumes at runtime.
I have been wondering about nv-codec-headers as we are at:
but I am unsure about updating to:
   https://github.com/FFmpeg/nv-codec-headers/releases/tag/n12.2.72.0
because if you look at:
   https://github.com/FFmpeg/nv-codec-headers/releases/
the release versions go from 12.xx to 8.x and it is really weird AND there is no year on the release dates but just day and month.
Since it is such an important part of ffmpeg inside CinGG, I am concerned but will at least try the 12.2.72.0 just to see what it does.

in theory it should give users of new nvidia hardware av1 encoding ...... but not sure how it will work with older drivers and hardware.

ffmpeg 7.1 itself is apparently capable to do AV1 accelerated encodings:

ffmpeg -hide_banner -encoders | egrep -i 'av1_nvenc|av1_qsv|av1_vaapi|av1_vulkan'
 V....D av1_nvenc            NVIDIA NVENC av1 encoder (codec av1)
 V..... av1_qsv              AV1 (Intel Quick Sync Video acceleration) (codec av1)
 V....D av1_vaapi            AV1 (VAAPI) (codec av1)

and awaiting for the upcoming av1_vulkan next ......... 😉


you can try to install something like nv-codec-headers and then add

Andrew,
As far as there might be a workaround also for the nvenc tff interlace issue, I didn't do more about the latter than searching the most similar package
ffnvcodec-devel (FFmpeg version of NVIDIA codec API headers)

Additional I think an AppImage built successful of my dynamic build ffmpeg-7.1 with
sh ./bld_appimage.sh bin_use_system_ffmpeg-71
It works on the build-machine, and I will test it on the older machines too.

Tested this appimage with system FFmpeg 7.1 on SkyLake w/dual dGPU NV GTX 960 + iGPU Intel HD 530:

h265_nvenc with workaround switching Cingg Format tff interlaced to Not interlaced
 ** rendered 5972 frames in 62.890 secs, 94.959 fps

hevc_qsv rendered ok directly w/audio
 ** rendered 5972 frames in 151.656 secs, 39.379 fps

------------------------

Tested on KabyLake (Dell XPS-13/9370) with system FFmpeg 7.1 and  iGPU Intel UHD 620:
 
hevc_qsv rendered  ok directly w/audio
** rendered 5972 frames in 91.944 secs, 64.953 fps
audio0 pad 64 0 (64)



Phyllis,
I was about to send a little comment to your first News version, regarding relative "new" Intel hardware.
The SkyLake/ KabyLake test machines are from 2015/ 2016 respectively :)
Of course they have lesser codecs support than the relative new bult-machine.
