C Specification
When using vkGetPhysicalDeviceVideoCapabilitiesKHR to query the
capabilities for the input pVideoProfile
with
videoCodecOperation
specified as
VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_EXT
, the instance of
VkVideoDecodeH264CapabilitiesEXT structure must be chained to
VkVideoCapabilitiesKHR to get this H.264 decode profile specific
capabilities.
The VkVideoDecodeH264CapabilitiesEXT structure is defined as:
// Provided by VK_EXT_video_decode_h264
typedef struct VkVideoDecodeH264CapabilitiesEXT {
VkStructureType sType;
void* pNext;
uint32_t maxLevel;
VkOffset2D fieldOffsetGranularity;
VkExtensionProperties stdExtensionVersion;
} VkVideoDecodeH264CapabilitiesEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
maxLevel
is the maximum H.264 level supported by the device. -
fieldOffsetGranularity
- if Interlaced Video Content is suported, the maximum field offset granularity supported for the picture resource. -
stdExtensionVersion
is the specific H.264 extension name and version supported by this implementation.
