New workspace crate isolating the unsafe GPU<->encoder interop for zero-copy hardware video encoding. Every link is validated by a test on real Intel/Mesa/iHD hardware: - nv12: GPU RGBA->NV12 compute (BT.709 full-range), byte-exact vs a CPU reference. - vaapi: VAAPI hwcontext + h264_vaapi encode (CPU-fed NV12 -> valid H.264), and DRM-PRIME surface layout probing. - vk_device: a custom wgpu Vulkan device that adds VK_EXT_image_drm_format_modifier (+ external-memory fd/dma-buf) via the wgpu-hal device-from-raw path, so a tiled VAAPI surface can be imported. - dmabuf: import a VAAPI NV12 surface's tiled DMA-BUF as two aliasing wgpu textures (Y=R8, UV=RG8) at the plane offsets. - zerocopy test: render values via Vulkan straight into the VAAPI surface and read them back 100% correct -- proving the GPU writes into the encoder surface with no CPU copy. Not yet wired into the editor; real-frame render + encode-from-surface + fallback wiring follow. Linux-only (libva); other platforms fall back. |
