…Utils Enable cross-process YCbCr image sharing via DMA-BUF (Linux) or NT handles (Windows) with proper tiled layouts for video encoders. VulkanDeviceMemoryImpl: - CreateWithExport(): Allocate with VkExportMemoryAllocateInfo - ExportNativeHandle(): Export DMA-BUF FD or NT handle - GetMemoryTypeIndex(): For opaque FD cross-process import - IsExportable(), GetExportHandleTypes() accessors VkImageResource: - CreateExportable(): Images with DRM modifiers and export handles - GetDrmFormatModifier(), UsesDrmFormatModifier() accessors - GetMemoryPlaneCount(), GetMemoryPlaneLayout() for plane info - GetImageTiling(), IsLinearImage(), GetPlaneLayout() helpers - Query actual DRM modifier from driver after image creation Bug fixes: - Handle DRM_FORMAT_MOD_LINEAR (value 0) correctly - check DMA_BUF handle type instead of modifier value to determine DRM tiling - Add VkImageFormatListCreateInfo for MUTABLE_FORMAT with DRM modifiers (VUID-VkImageCreateInfo-tiling-02353) Signed-off-by: Tony Zlatinski <tzlatinski@nvidia.com>
Python test scripts for H.264, H.265, AV1, VP9 decoder and H.264, H.265, AV1 encoder with Adaptive Quantization (AQ) support. Works on Linux and Windows. Python scripts (cross-platform): - run_decoder_tests.py: Decoder tests for all codecs - run_encoder_tests.py: Encoder tests with AQ support - run_all_video_tests.py: Unified test runner - vulkan_video_test.py: Full framework with JSON reporting Shell scripts (Linux only, legacy): - run_decoder_tests.sh, run_encoder_tests.sh, run_all_video_tests.sh Key features: - Required --video-dir parameter (no default content directory) - Validates video directory exists before running tests - Remote execution via SSH (default: 127.0.0.1/localhost) - --remote <host> to specify remote host - --local flag for local execution (required on Windows) - Vulkan validation layer support (--validate) - Codec filtering (--codec h264|h265|av1|vp9) - Quick test mode (--quick) - ANSI color output (auto-detected on Windows Terminal) Signed-off-by: Tony Zlatinski <tzlatinski@nvidia.com>

…/export Add comprehensive test application for DRM format modifier support in Vulkan, covering LINEAR and block-linear (optimal tiling) modifiers for multiplanar YCbCr formats. Test application (drm_format_mod_test): - Query and enumerate DRM format modifiers per format - Export images via VK_EXT_image_drm_format_modifier + VK_KHR_external_memory_fd - Import via DMA-BUF fd with plane layout propagation - Round-trip validation: export -> import -> verify matching layouts - Block-linear import using VkImageDrmFormatModifierListCreateInfoEXT - Vendor-aware modifier decoding (NVIDIA block-linear fields) - Compression modifier detection and --compression CLI option - Supports NV12, P010, P012, P016, NV16, P210 VkCodecUtils infrastructure changes: - VkImageResource: Add dedicated memory allocation for DMA-BUF exportable images (VkMemoryDedicatedAllocateInfo) - VulkanDeviceMemoryImpl: Fix dedicated allocation size calculation and DRM modifier memory requirements query Build: integrated into common/libs/tests/ CMake build system.
