Code Review
This pull request implements Vulkan hardware acceleration support, including a new libvulkan-sys crate for FFI bindings and capability probing for decoders and encoders. It also adds a probe-capabilities utility to inspect hardware acceleration features across various backends. Review feedback highlights potential thread-safety issues with environment variable usage in VAAPI probing, the fragility of the CapsBuf structure for Vulkan capabilities, and a recommendation to lower the requested Vulkan API version for better driver compatibility.
Also adds a standalone binary in ffpipeline that allows pretty-printing capabilities for given hardware accels. Useful for debugging your system!
