Field Documentation

◆ tiling

VkImageTiling AVVulkanFramesContext::tiling

Controls the tiling of allocated frames.

Definition at line 116 of file hwcontext_vulkan.h.

Referenced by try_export_flags(), vulkan_frames_init(), and vulkan_pool_alloc().

◆ usage

VkImageUsageFlagBits AVVulkanFramesContext::usage

Defines extra usage of output frames.

If left as 0, the following bits are set: TRANSFER_SRC, TRANSFER_DST. SAMPLED and STORAGE.

◆ create_pnext

void* AVVulkanFramesContext::create_pnext

Extension data for image creation.

Definition at line 125 of file hwcontext_vulkan.h.

Referenced by vulkan_frames_init(), and vulkan_pool_alloc().

◆ alloc_pnext

void* AVVulkanFramesContext::alloc_pnext[AV_NUM_DATA_POINTERS]

Extension data for memory allocation.

Must have as many entries as the number of planes of the sw_format. This will be chained to VkExportMemoryAllocateInfo, which is used to make all pool images exportable to other APIs if the necessary extensions are present in enabled_dev_extensions.
