• VIDEO_CHROMA_SUBSAMPLING_422_BIT_KHR - the format is 4:2:2 chroma subsampled. The two chroma components are sampled at half the sample rate of luma. The horizontal chroma resolution is halved.
• VIDEO_CHROMA_SUBSAMPLING_444_BIT_KHR - the format is 4:4:4 chroma sampled. Each of the three YCbCr components have the same sample rate, thus there is no chroma subsampling.

Enum values:

• VIDEO_CHROMA_SUBSAMPLING_INVALID_BIT_KHR

VK_VIDEO_COMPONENT_BIT_DEPTH_INVALID_KHR, VK_VIDEO_COMPONENT_BIT_DEPTH_8_BIT_KHR, VK_VIDEO_COMPONENT_BIT_DEPTH_10_BIT_KHR, VK_VIDEO_COMPONENT_BIT_DEPTH_12_BIT_KHR

• VIDEO_COMPONENT_BIT_DEPTH_10_BIT_KHR - the format component bit depth is 10 bits.
• VIDEO_COMPONENT_BIT_DEPTH_12_BIT_KHR - the format component bit depth is 12 bits.

Enum values:

• VIDEO_COMPONENT_BIT_DEPTH_INVALID_KHR

VK_VIDEO_CAPABILITY_PROTECTED_CONTENT_BIT_KHR, VK_VIDEO_CAPABILITY_SEPARATE_REFERENCE_IMAGES_BIT_KHR

VkVideoCapabilityFlagBitsKHR - Video Decode and Encode Capability Flags

Description

• VIDEO_CAPABILITY_PROTECTED_CONTENT_BIT_KHR - the decode or encode session supports protected content.
• VIDEO_CAPABILITY_SEPARATE_REFERENCE_IMAGES_BIT_KHR - the DPB or Reconstructed Video Picture Resources for the video session may be created as a separate VkImage for each DPB picture. If not supported, the DPB must be created as single multi-layered image where each layer represents one of the DPB Video Picture Resources.

VK_VIDEO_SESSION_CREATE_DEFAULT_KHR, VK_VIDEO_SESSION_CREATE_PROTECTED_CONTENT_BIT_KHR

VkVideoSessionCreateFlagBitsKHR - Video decode or encode video session creation flags

Description

• VIDEO_SESSION_CREATE_PROTECTED_CONTENT_BIT_KHR - create the video session for use with protected video content

Enum values:

• VIDEO_SESSION_CREATE_DEFAULT_KHR

VK_VIDEO_CODING_CONTROL_DEFAULT_KHR, VK_VIDEO_CODING_CONTROL_RESET_BIT_KHR

VkVideoCodingControlFlagBitsKHR - Video Coding Control Command Flags

Description

• VIDEO_CODING_CONTROL_DEFAULT_KHR indicates a request for the coding control paramaters to be applied to the current state of the bound video session.
• VIDEO_CODING_CONTROL_RESET_BIT_KHR indicates a request for the bound video session device context to be reset before the coding control parameters are applied.

A newly created video session must be reset before use for video decode or encode operations. The reset operation returns all session DPB slots to the unused state (see DPB Slot States). For encode sessions, the reset operation returns rate control configuration to implementation default settings. After decode or encode operations are performed on a session, the reset operation may be used to return the video session device context to the same initial state as after the reset of a newly created video session. This may be used when different video sequences are processed with the same session.

VK_VIDEO_CODING_QUALITY_PRESET_NORMAL_BIT_KHR, VK_VIDEO_CODING_QUALITY_PRESET_POWER_BIT_KHR, VK_VIDEO_CODING_QUALITY_PRESET_QUALITY_BIT_KHR

VkVideoCodingQualityPresetFlagBitsKHR - Video codec profile types

Description

• VIDEO_CODING_QUALITY_PRESET_NORMAL_BIT_KHR defines normal decode case.
• VIDEO_CODING_QUALITY_PRESET_POWER_BIT_KHR defines power efficient case.
• VIDEO_CODING_QUALITY_PRESET_QUALITY_BIT_KHR defines quality focus case.

VK_QUERY_RESULT_STATUS_ERROR_KHR, VK_QUERY_RESULT_STATUS_NOT_READY_KHR, VK_QUERY_RESULT_STATUS_COMPLETE_KHR

VkQueryResultStatusKHR - Specific status codes for operations

Description

• QUERY_RESULT_STATUS_NOT_READY_KHR specifies that the query result is not yet available.
• QUERY_RESULT_STATUS_ERROR_KHR specifies that operations did not complete successfully.
• QUERY_RESULT_STATUS_COMPLETE_KHR specifies that operations completed successfully and the query result is available.

                                                              VkPhysicalDeviceVideoFormatInfoKHR pVideoFormatInfo,
                                                              java.nio.IntBuffer pVideoFormatPropertyCount,
                                                              @Nullable
                                                              VkVideoFormatPropertiesKHR.Buffer pVideoFormatProperties)

Query supported Video Decode and Encode image formats.

C Specification

To enumerate the supported output, input and DPB image formats for a specific codec operation and video profile, call:

 VkResult vkGetPhysicalDeviceVideoFormatPropertiesKHR(
     VkPhysicalDevice                            physicalDevice,
     const VkPhysicalDeviceVideoFormatInfoKHR*   pVideoFormatInfo,
     uint32_t*                                   pVideoFormatPropertyCount,
     VkVideoFormatPropertiesKHR*                 pVideoFormatProperties);

Description

If pVideoFormatProperties is NULL, then the number of video format properties supported for the given physicalDevice is returned in pVideoFormatPropertyCount. Otherwise, pVideoFormatPropertyCount must point to a variable set by the user to the number of elements in the pVideoFormatProperties array, and on return the variable is overwritten with the number of values actually written to pVideoFormatProperties. If the value of pVideoFormatPropertyCount is less than the number of video format properties supported, at most pVideoFormatPropertyCount values will be written to pVideoFormatProperties, and INCOMPLETE will be returned instead of SUCCESS, to indicate that not all the available values were returned.

Valid Usage

• The imageUsage enum of VkPhysicalDeviceVideoFormatInfoKHR must contain at least one of the following video image usage bit(s): IMAGE_USAGE_VIDEO_DECODE_DST_BIT_KHR, IMAGE_USAGE_VIDEO_DECODE_DPB_BIT_KHR, IMAGE_USAGE_VIDEO_ENCODE_SRC_BIT_KHR, or IMAGE_USAGE_VIDEO_ENCODE_DPB_BIT_KHR

Note:

For most use cases, only decode or encode related usage flags are going to be specified. For a use case such as transcode, if the image were to be shared between decode and encode session(s), then both decode and encode related usage flags can be set.

Valid Usage (Implicit)

• physicalDevice must be a valid VkPhysicalDevice handle
• pVideoFormatInfo must be a valid pointer to a valid VkPhysicalDeviceVideoFormatInfoKHR structure
• pVideoFormatPropertyCount must be a valid pointer to a uint32_t value
• If the value referenced by pVideoFormatPropertyCount is not 0, and pVideoFormatProperties is not NULL, pVideoFormatProperties must be a valid pointer to an array of pVideoFormatPropertyCount VkVideoFormatPropertiesKHR structures

Return Codes

On success, this command returns

• SUCCESS
• INCOMPLETE

On failure, this command returns

• ERROR_EXTENSION_NOT_PRESENT
• ERROR_INITIALIZATION_FAILED
• ERROR_FORMAT_NOT_SUPPORTED

Get Memory Requirements.

C Specification

To get memory requirements for a video session, call:

 VkResult vkGetVideoSessionMemoryRequirementsKHR(
     VkDevice                                    device,
     VkVideoSessionKHR                           videoSession,
     uint32_t*                                   pVideoSessionMemoryRequirementsCount,
     VkVideoGetMemoryPropertiesKHR*              pVideoSessionMemoryRequirements);

Description

If pVideoSessionMemoryRequirements is NULL, then the number of memory heap types required for the video session is returned in pVideoSessionMemoryRequirementsCount. Otherwise, pVideoSessionMemoryRequirementsCount must point to a variable set by the user with the number of elements in the pVideoSessionMemoryRequirements array, and on return the variable is overwritten with the number of formats actually written to pVideoSessionMemoryRequirements. If pVideoSessionMemoryRequirementsCount is less than the number of memory heap types required for the video session, then at most pVideoSessionMemoryRequirementsCount elements will be written to pVideoSessionMemoryRequirements, and INCOMPLETE will be returned, instead of SUCCESS, to indicate that not all required memory heap types were returned.

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• videoSession must be a valid VkVideoSessionKHR handle
• pVideoSessionMemoryRequirementsCount must be a valid pointer to a uint32_t value
• If the value referenced by pVideoSessionMemoryRequirementsCount is not 0, and pVideoSessionMemoryRequirements is not NULL, pVideoSessionMemoryRequirements must be a valid pointer to an array of pVideoSessionMemoryRequirementsCount VkVideoGetMemoryPropertiesKHR structures
• videoSession must have been created, allocated, or retrieved from device

On success, this command returns

• SUCCESS
• INCOMPLETE

On failure, this command returns

• ERROR_INITIALIZATION_FAILED
