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 ......... 😉

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)
