C Specification

The VkPhysicalDeviceVideoFormatInfoKHR input structure is defined as:

// Provided by VK_KHR_video_queue
typedef struct VkPhysicalDeviceVideoFormatInfoKHR {
    VkStructureType              sType;
    void*                        pNext;
    VkImageUsageFlags            imageUsage;
    const VkVideoProfilesKHR*    pVideoProfiles;
} VkPhysicalDeviceVideoFormatInfoKHR;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • imageUsage is a bitmask of VkImageUsageFlagBits specifying intended video image usages.

  • pVideoProfiles is a pointer to a VkVideoProfilesKHR structure providing the video profile(s) of video session(s) that will use the image. For most use cases, the image is used by a single video session and a single video profile is provided. For a use case such as transcode, where a decode session output image may be used as encode input for one or more encode sessions, multiple video profiles representing the video sessions that will share the image may be provided.

Description

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceVideoFormatInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VIDEO_FORMAT_INFO_KHR

  • VUID-VkPhysicalDeviceVideoFormatInfoKHR-pNext-pNext
    pNext must be NULL
