C Specification
A video profile is defined by VkVideoProfileKHR structure as:
// Provided by VK_KHR_video_queue
typedef struct VkVideoProfileKHR {
VkStructureType sType;
const void* pNext;
VkVideoCodecOperationFlagBitsKHR videoCodecOperation;
VkVideoChromaSubsamplingFlagsKHR chromaSubsampling;
VkVideoComponentBitDepthFlagsKHR lumaBitDepth;
VkVideoComponentBitDepthFlagsKHR chromaBitDepth;
} VkVideoProfileKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
videoCodecOperationis a VkVideoCodecOperationFlagBitsKHR value specifying a video codec operation. -
chromaSubsamplingis a bitmask of VkVideoChromaSubsamplingFlagBitsKHR specifying video chroma subsampling information. -
lumaBitDepthis a bitmask of VkVideoComponentBitDepthFlagBitsKHR specifying video luma bit depth information. -
chromaBitDepthis a bitmask of VkVideoComponentBitDepthFlagBitsKHR specifying video chroma bit depth information.
Description
When a VkVideoProfileKHR structure is specified through the
pProfiles member of an VkVideoProfilesKHR structure in the
pNext chain of the input parameter of a query command such as
vkGetPhysicalDeviceVideoCapabilitiesKHR,
vkGetPhysicalDeviceVideoFormatPropertiesKHR, or
vkGetPhysicalDeviceImageFormatProperties2, the following error codes
indicate specific causes of the failure of the query operation:
-
VK_ERROR_VIDEO_PICTURE_LAYOUT_NOT_SUPPORTED_KHRThe requested video picture layout (e.g. through thepictureLayoutmember of a VkVideoDecodeH264ProfileEXT structure included in thepNextchain ofVkVideoProfileKHR) is not supported. -
VK_ERROR_VIDEO_PROFILE_OPERATION_NOT_SUPPORTED_KHRA video profile operation specified byvideoCodecOperationis not supported. -
VK_ERROR_VIDEO_PROFILE_FORMAT_NOT_SUPPORTED_KHRFormat parameters specified bychromaSubsampling,lumaBitDepth, orchromaBitDepthare not supported. -
VK_ERROR_VIDEO_PROFILE_CODEC_NOT_SUPPORTED_KHRCodec-specific parameters corresponding to thevideoCodecOperationare not provided through thepNextchain ofVkVideoProfileKHR, or the specified parameters are not supported.
