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
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
maxLevelIdcis aStdVideoH264LevelIdcvalue indicating the maximum H.264 level supported by the profile, where enum constantSTD_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. -
fieldOffsetGranularityis the minimum alignment for VkVideoPictureResourceInfoKHR::codedOffsetspecified for a video picture resource when using the picture layout VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_SEPARATE_PLANES_BIT_KHR.
