[Cin]thirdparty ffmpeg-8.0 vs system ffmpeg-8.0.1

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.
