Worked on enhancing video rendering quality in the AvaloniaUI/angle repository by improving Vulkan YUV DmaBuf sampling. Focused on aligning the Vulkan backend with YUV AHB specifications, the work involved updating the default texture sampling filter to VK_FILTER_LINEAR and refining the YUV conversion path to use vk::kDefaultYCbCrChromaFilter instead of VK_FILTER_NEAREST. These changes, implemented in C++ with expertise in graphics programming and low-level systems, reduced sampling artifacts and improved color accuracy for YUV formats. The feature established a more consistent and efficient approach to texture handling, laying the foundation for future improvements in Vulkan-based video rendering.
