I fighted libplacebo and not sure who won - there is no Vulkan device in qemu VM!
Try when you can and tell me what works?
I did not include 16bpc crash fixes there, but without specifical env. variable those old new formats should not show up
Extracted the AppImage and copied the h264_vulkan_8b420.mp4 preset to squashfs-root/usr/bin/ffmpeg/video
Second run with
export ANV_DEBUG="video-decode,video-encode"

Good news. Vulkan rendering works now on my Dell XPX 13 (9370) ultrabook (Intel gen8 Coffee Lake w/ i7/UHD 620). hdv.m2t -> preset h264_vulkan.mp4, rendering at ~140 fps This is max capability of this 2017/18 hardware (not hevc_vulkan) and confirms what I got with native ffmpeg-8. Therefore I think the reason it didn't work above on the newer gen12 Alder Lake w/DG2 (Arc A750), is due to the bug I have reported to Mesa regarding this hardware. https://gitlab.freedesktop.org/mesa/mesa/-/issues/14449#note_3238156
