C Specification
To attach memory to a video session object, call:
// Provided by VK_KHR_video_queue
VkResult vkBindVideoSessionMemoryKHR(
VkDevice device,
VkVideoSessionKHR videoSession,
uint32_t bindSessionMemoryInfoCount,
const VkBindVideoSessionMemoryInfoKHR* pBindSessionMemoryInfos);
Parameters
-
deviceis the logical device that owns the video session. -
videoSessionis the video session to be bound with device memory. -
bindSessionMemoryInfoCountis the number of elements inpBindSessionMemoryInfos. -
pBindSessionMemoryInfosis a pointer to an array ofbindSessionMemoryInfoCountVkBindVideoSessionMemoryInfoKHR structures specifying memory regions to be bound to specific memory bindings of the video session.
Description
The valid usage statements below refer to the VkMemoryRequirements
structure corresponding to a specific element of
pBindSessionMemoryInfos, which is defined as follows:
-
If the
memoryBindIndexmember of the element ofpBindSessionMemoryInfosin question matches thememoryBindIndexmember of one of the elements returned inpMemoryRequirementswhen vkGetVideoSessionMemoryRequirementsKHR is called with the samevideoSessionand withpMemoryRequirementsCountequal tobindSessionMemoryInfoCount, then thememoryRequirementsmember of that element ofpMemoryRequirementsis the VkMemoryRequirements structure corresponding to the element ofpBindSessionMemoryInfosin question. -
Otherwise the element of
pBindSessionMemoryInfosin question is said to not have a corresponding VkMemoryRequirements structure.
