Pointer to the instance-provided vkGetInstanceProcAddr loading function.

If NULL, will pick either libvulkan or libvolk, depending on libavutil's compilation settings, and set this field.

This structure should be set to the set of features that present and enabled during device creation.

When a device is created by FFmpeg, it will default to enabling all that are present of the shaderImageGatherExtended, fragmentStoresAndAtomics, shaderInt64 and vertexPipelineStoresAndAtomics features.

Enabled instance extensions.

If supplying your own device context, set this to an array of strings, with each entry containing the specified Vulkan extension string to enable. Duplicates are possible and accepted. If no extensions are enabled, set these fields to NULL, and 0 respectively.

Enabled device extensions.

By default, VK_KHR_external_memory_fd, VK_EXT_external_memory_dma_buf, VK_EXT_image_drm_format_modifier, VK_KHR_external_semaphore_fd and VK_EXT_external_memory_host are enabled if found. If supplying your own device context, these fields takes the same format as the above fields, with the same conditions that duplicates are possible and accepted, and that NULL and 0 respectively means no extensions are enabled.

Queue family index for graphics operations, and the number of queues enabled for it.

If unavaiable, will be set to -1. Not required. av_hwdevice_create() will attempt to find a dedicated queue for each queue family, or pick the one with the least unrelated flags set. Queue indices here may overlap if a queue has to share capabilities.
