VkVideoDecodeH264CapabilitiesKHR(3)

Name

VkVideoDecodeH264CapabilitiesKHR - Structure describing H.264 decode capabilities

C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities for an H.264 decode profile, the VkVideoCapabilitiesKHR::pNext chain must include a VkVideoDecodeH264CapabilitiesKHR structure that will be filled with the profile-specific capabilities.

The VkVideoDecodeH264CapabilitiesKHR structure is defined as:

// Provided by VK_KHR_video_decode_h264
typedef struct VkVideoDecodeH264CapabilitiesKHR {
    VkStructureType         sType;
    void*                   pNext;
    StdVideoH264LevelIdc    maxLevelIdc;
    VkOffset2D              fieldOffsetGranularity;
} VkVideoDecodeH264CapabilitiesKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • maxLevelIdc is a StdVideoH264LevelIdc value indicating the maximum H.264 level supported by the profile, where enum constant STD_VIDEO_H264_LEVEL_IDC_<major>_<minor> identifies H.264 level <major>.<minor> as defined in section A.3 of the ITU-T H.264 Specification.

  • fieldOffsetGranularity is the minimum alignment for VkVideoPictureResourceInfoKHR::codedOffset specified for a video picture resource when using the picture layout VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_SEPARATE_PLANES_BIT_KHR.

Description

Valid Usage (Implicit)

  • VUID-VkVideoDecodeH264CapabilitiesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H264_CAPABILITIES_KHR
