Field Documentation

img

VkImage AVVkFrame::img[AV_NUM_DATA_POINTERS]

Vulkan images to which the memory is bound to.

Definition at line 153 of file hwcontext_vulkan.h.

Referenced by process_frames().

tiling

VkImageTiling AVVkFrame::tiling

The same tiling must be used for all images in the frame.

Definition at line 158 of file hwcontext_vulkan.h.

mem

VkDeviceMemory AVVkFrame::mem[AV_NUM_DATA_POINTERS]

Memory backing the images.

Could be less than the amount of images if importing from a DRM or VAAPI frame.

Definition at line 164 of file hwcontext_vulkan.h.

size

size_t AVVkFrame::size[AV_NUM_DATA_POINTERS]

Definition at line 165 of file hwcontext_vulkan.h.

flags

VkMemoryPropertyFlagBits AVVkFrame::flags

OR'd flags for all memory allocated.

Definition at line 170 of file hwcontext_vulkan.h.

access

VkAccessFlagBits AVVkFrame::access[AV_NUM_DATA_POINTERS]

Updated after every barrier.

Definition at line 175 of file hwcontext_vulkan.h.

Referenced by process_frames().

layout

VkImageLayout AVVkFrame::layout[AV_NUM_DATA_POINTERS]

Definition at line 176 of file hwcontext_vulkan.h.

Referenced by process_frames().

sem

VkSemaphore AVVkFrame::sem[AV_NUM_DATA_POINTERS]

Synchronization semaphores.

Must not be freed manually. Must be waited on and signalled at every queue submission. Could be less than the amount of images: either one per VkDeviceMemory or one for the entire frame. All others will be set to VK_NULL_HANDLE.

Definition at line 184 of file hwcontext_vulkan.h.

internal

struct AVVkFrameInternal* AVVkFrame::internal

Internal data.

Definition at line 189 of file hwcontext_vulkan.h.
