I build a standard single-user, static bundled Cingg and looked at the thirdparty ffmpeg-8.0

cd /cinelerra/cinelerra-5.1/thirdparty/ffmpeg-8.0

Trying to verify its available hwaccels methods:
./ffmpeg -hwaccels
Hardware acceleration methods:
vdpau
cuda
vaapi

Verifying the same with my system ffmpeg-8.0.1 on Tumbleweed-Slowroll I get
ffmpeg -hide_banner -hwaccels
Hardware acceleration methods:
vdpau
cuda
vaapi
qsv
drm
vulkan

I wonder why not also the thirdparty ffmpeg-8.0 does list "qsv" and "vulkan"?
Seemingly among encoders "--enable-libvpl" and "--enable-vulkan" are listed. 


Honestly, no idea. Try to verify that all switches you passed to configure reflected well in ffmpeg-8.0/ffbuild/config.log


First my simple build-steps

cd /home3
git clone https://git.cinelerra-gg.org/goodguy/cinelerra.git
cd /home3/cinelerra/cinelerra-5.1 
./bld.sh

which ran through without stops


cd /home3/cinelerra/cinelerra-5.1/thirdparty/ffmpeg-8.0/ffbuild

cat config.log | egrep -i "libvpl|vulkan"

# ./configure --enable-pthreads --disable-avdevice --enable-gpl --disable-ffplay --disable-doc --enable-vaapi --enable-vdpau --disable-libvpl --disable-vulkan --disable-libplacebo 

..............a lot more...... snip


What confuse me here are "--disable-libvpl --disable-vulkan"
though that there is a list below regarding vulkan and minor about qsv/libvpl
ffv1_vulkan_encoder
av1_vulkan_encoder
h264_vulkan_encoder
hevc_vulkan_encoder
av1_vulkan_hwaccel
ffv1_vulkan_hwaccel
h264_vulkan_hwaccel
hevc_vulkan_hwaccel
prores_raw_vulkan_hwaccel
vp9_vulkan_hwaccel
avgblur_vulkan_filter
....
av1_qsv_encoder_deps=libvpl
