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;

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_KHR The requested video picture layout (e.g. through the pictureLayout member of a VkVideoDecodeH264ProfileEXT structure included in the pNext chain of VkVideoProfileKHR) is not supported.

  • VK_ERROR_VIDEO_PROFILE_OPERATION_NOT_SUPPORTED_KHR A video profile operation specified by videoCodecOperation is not supported.

  • VK_ERROR_VIDEO_PROFILE_FORMAT_NOT_SUPPORTED_KHR Format parameters specified by chromaSubsampling, lumaBitDepth, or chromaBitDepth are not supported.

  • VK_ERROR_VIDEO_PROFILE_CODEC_NOT_SUPPORTED_KHR Codec-specific parameters corresponding to the videoCodecOperation are not provided through the pNext chain of VkVideoProfileKHR, or the specified parameters are not supported.

Valid Usage (Implicit)
  • VUID-VkVideoProfileKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_PROFILE_KHR

  • VUID-VkVideoProfileKHR-videoCodecOperation-parameter
    videoCodecOperation must be a valid VkVideoCodecOperationFlagBitsKHR value

  • VUID-VkVideoProfileKHR-chromaSubsampling-parameter
    chromaSubsampling must be a valid combination of VkVideoChromaSubsamplingFlagBitsKHR values

  • VUID-VkVideoProfileKHR-chromaSubsampling-requiredbitmask
    chromaSubsampling must not be 0

  • VUID-VkVideoProfileKHR-lumaBitDepth-parameter
    lumaBitDepth must be a valid combination of VkVideoComponentBitDepthFlagBitsKHR values

  • VUID-VkVideoProfileKHR-lumaBitDepth-requiredbitmask
    lumaBitDepth must not be 0

  • VUID-VkVideoProfileKHR-chromaBitDepth-parameter
    chromaBitDepth must be a valid combination of VkVideoComponentBitDepthFlagBitsKHR values

  • VUID-VkVideoProfileKHR-chromaBitDepth-requiredbitmask
    chromaBitDepth must not be 0
