FFmpeg's Vulkan Video decoder now runs on the PRESENTER's own VkDevice — the decoded VkImage feeds the existing CICP CSC pass directly: zero copy, no interop, and NVIDIA gets hardware decode for the first time (its VAAPI is unusable by design). One decode architecture for every vendor going forward; VAAPI-dmabuf and software remain the fallbacks (auto: vulkan → vaapi → software; PUNKTFUNK_DECODER=vulkan pins it). Presenter: instance 1.3; probes VK_KHR_video_queue/decode_queue + codec extensions, a VIDEO_DECODE queue family (+ its codec caps via QueueFamilyVideoPropertiesKHR), and the samplerYcbcrConversion/ timelineSemaphore/synchronization2 features — all enabled at device creation when present, exported as a VulkanDecodeDevice handle bundle. Decoder: AVVulkanDeviceContext built over those handles via pf-ffvk (features chain, extension lists, deprecated queue indices + the qf[] map); get_format supplies OUR frames context with MUTABLE_FORMAT so the presenter's per-plane views are legal; output is DecodedImage::VkFrame carrying AVVkFrame/frames-ctx pointers plus the lock fns. Present: R8+R8G8 plane views over the multiplanar image, the live sync state read under the AVVulkanFramesContext lock, a timeline-semaphore wait(sem_value)/signal(sem_value+1) folded into the submit, layout/ queue-family/sem_value written back per FFmpeg's contract, and the frame guard parked in the retire queue until the fence. CSC pass + video framebuffer are now unconditional (NVIDIA has no dmabuf-import path). Verified on the RTX 5070 Ti: device creates with decode_qf=3, caps=DECODE_H264|H265|AV1|VP9; swapchain unaffected. Live stream validation next. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
