ffmpeg-sys-next binds a curated header list that omits every hwcontext_*.h, so AVVulkanDeviceContext/AVVulkanFramesContext/AVVkFrame — the surface that lets FFmpeg's Vulkan Video decoder run on the presenter's own VkDevice and hand the decoded VkImages back — had no Rust bindings at all. pf-ffvk generates them at build time from the SYSTEM headers, which is the only ABI-safe option: the struct layout depends on FF_API_* deprecation gates resolved in libavutil/version.h (confirmed: FFmpeg 8.1 still carries the FIXED_QUEUES fields). Ships ash<->vulkan.h handle conversions; opaque AVHW*/AVFrame types keep ffmpeg-sys-next the owner of the core surface (pointer casts across). Needs vulkan-headers (Arch) / libvulkan-dev (CI, added); PF_FFVK_VULKAN_INCLUDE overrides for cross builds. Verified: bindgen layout tests pass, av_vk_frame_alloc links and zero-initializes.
