Main Vulkan context, allocated as AVHWDeviceContext.hwctx.
All of these can be set before init to change what the context uses
Definition at line 59 of file hwcontext_vulkan.h.
const VkAllocationCallbacks* AVVulkanDeviceContext::alloc |
Custom memory allocator, else NULL.
Definition at line 63 of file hwcontext_vulkan.h.
PFN_vkGetInstanceProcAddr AVVulkanDeviceContext::get_proc_addr |
Pointer to a vkGetInstanceProcAddr loading function.
If unset, will dynamically load and use libvulkan.
Definition at line 69 of file hwcontext_vulkan.h.
VkInstance AVVulkanDeviceContext::inst |
VkPhysicalDevice AVVulkanDeviceContext::phys_dev |
Physical device.
Definition at line 79 of file hwcontext_vulkan.h.
VkDevice AVVulkanDeviceContext::act_dev |
Active device.
Definition at line 84 of file hwcontext_vulkan.h.
VkPhysicalDeviceFeatures2 AVVulkanDeviceContext::device_features |
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.
Definition at line 92 of file hwcontext_vulkan.h.
const char* const* AVVulkanDeviceContext::enabled_inst_extensions |
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.
Definition at line 101 of file hwcontext_vulkan.h.
int AVVulkanDeviceContext::nb_enabled_inst_extensions |
Definition at line 102 of file hwcontext_vulkan.h.
const char* const* AVVulkanDeviceContext::enabled_dev_extensions |
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.

Definition at line 113 of file hwcontext_vulkan.h.
attribute_deprecated int AVVulkanDeviceContext::queue_family_index |
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.

Definition at line 126 of file hwcontext_vulkan.h.
attribute_deprecated int AVVulkanDeviceContext::queue_family_tx_index |
Queue family index for transfer operations and the number of queues enabled.
Required.

attribute_deprecated int AVVulkanDeviceContext::nb_tx_queues |
Definition at line 135 of file hwcontext_vulkan.h.
attribute_deprecated int AVVulkanDeviceContext::queue_family_comp_index |

Definition at line 144 of file hwcontext_vulkan.h.
attribute_deprecated int AVVulkanDeviceContext::queue_family_encode_index |
Queue family index for video encode ops, and the amount of queues enabled.
If the device doesn't support such, queue_family_encode_index will be -1. Not required.

void(* AVVulkanDeviceContext::lock_queue) (struct AVHWDeviceContext *ctx, uint32_t queue_family, uint32_t index) |
Locks a queue, preventing other threads from submitting any command buffers to this queue.
If set to NULL, will be set to lavu-internal functions that utilize a mutex.
Definition at line 173 of file hwcontext_vulkan.h.
void(* AVVulkanDeviceContext::unlock_queue) (struct AVHWDeviceContext *ctx, uint32_t queue_family, uint32_t index) |
Similar to lock_queue(), unlocks a queue.
Must only be called after locking.
Definition at line 178 of file hwcontext_vulkan.h.
AVVulkanDeviceQueueFamily AVVulkanDeviceContext::qf[64] |
Queue families used.
Must be preferentially ordered. List may contain duplicates.
For compatibility reasons, all the enabled queue families listed above (queue_family_(tx/comp/encode/decode)_index) must also be included in this list until they're removed after deprecation.
