Class KHRVideoEncodeQueue

java.lang.Object

org.lwjgl.vulkan.KHRVideoEncodeQueue

public class KHRVideoEncodeQueue
extends Object

This extension builds upon the VK_KHR_video_queue extension by adding common APIs specific to video encoding and thus enabling implementations to expose queue families supporting video encode operations.

More specifically, it adds video encode specific capabilities and a new command buffer command that allows recording video encode operations against a video session.

This extension is to be used in conjunction with other codec specific video encode extensions that enable encoding video sequences of specific video compression standards.

VK_VIDEO_ENCODE_CAPABILITY_PRECEDING_EXTERNALLY_ENCODED_BYTES_BIT_KHR

public static final int VK_VIDEO_ENCODE_CAPABILITY_PRECEDING_EXTERNALLY_ENCODED_BYTES_BIT_KHR

VkVideoEncodeCapabilityFlagBitsKHR - Video encode capability flags

Description

• VIDEO_ENCODE_CAPABILITY_PRECEDING_EXTERNALLY_ENCODED_BYTES_BIT_KHR specifies that the implementation supports the use of VkVideoEncodeInfoKHR::precedingExternallyEncodedBytes.
• VIDEO_ENCODE_CAPABILITY_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_DETECTION_BIT_KHR specifies that the implementation is able to detect and report when the destination video bitstream buffer range provided by the application is not sufficiently large to fit the encoded bitstream data produced by a video encode operation by reporting the QUERY_RESULT_STATUS_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_KHR query result status code.

  Note

  Some implementations may not be able to reliably detect insufficient bitstream buffer range conditions in all situations. Such implementations will not report support for the VIDEO_ENCODE_CAPABILITY_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_DETECTION_BIT_KHR encode capability flag for the video profile, but may still report the QUERY_RESULT_STATUS_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_KHR query result status code in certain cases. Applications should always check for the specific query result status code QUERY_RESULT_STATUS_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_KHR even when this encode capability flag is not supported by the implementation for the video profile in question. However, applications must not assume that a different negative query result status code indicating an unsuccessful completion of a video encode operation is not the result of an insufficient bitstream buffer condition unless this encode capability flag is supported.

Unsafe version of: GetEncodedVideoSessionParametersKHR

Parameters:

vkGetEncodedVideoSessionParametersKHR

public static int vkGetEncodedVideoSessionParametersKHR(org.lwjgl.vulkan.VkDevice device,
 VkVideoEncodeSessionParametersGetInfoKHR pVideoSessionParametersInfo,
 @Nullable VkVideoEncodeSessionParametersFeedbackInfoKHR pFeedbackInfo,
 org.lwjgl.PointerBuffer pDataSize,
 @Nullable ByteBuffer pData)

Get encoded parameter sets from a video session parameters object.

C Specification

Encoded parameter data can be retrieved from a video session parameters object created with a video encode operation using the command:

 VkResult vkGetEncodedVideoSessionParametersKHR(
     VkDevice                                    device,
     const VkVideoEncodeSessionParametersGetInfoKHR* pVideoSessionParametersInfo,
     VkVideoEncodeSessionParametersFeedbackInfoKHR* pFeedbackInfo,
     size_t*                                     pDataSize,
     void*                                       pData);

Description

If pData is NULL, then the size of the encoded parameter data, in bytes, that can be retrieved is returned in pDataSize. Otherwise, pDataSize must point to a variable set by the application to the size of the buffer, in bytes, pointed to by pData, and on return the variable is overwritten with the number of bytes actually written to pData. If pDataSize is less than the size of the encoded parameter data that can be retrieved, then no data will be written to pData, zero will be written to pDataSize, and INCOMPLETE will be returned instead of SUCCESS, to indicate that no encoded parameter data was returned.

If pFeedbackInfo is not NULL then the members of the VkVideoEncodeSessionParametersFeedbackInfoKHR structure and any additional structures included in its pNext chain that are applicable to the video session parameters object specified in pVideoSessionParametersInfo→videoSessionParameters will be filled with feedback about the requested parameter data on all successful calls to this command.

Note

This includes the cases when pData is NULL or when INCOMPLETE is returned by the command, and enables the application to determine whether the implementation overrode any of the requested video session parameters without actually needing to retrieve the encoded parameter data itself.

nvkCmdEncodeVideoKHR

public static void nvkCmdEncodeVideoKHR(org.lwjgl.vulkan.VkCommandBuffer commandBuffer,
 long pEncodeInfo)

Unsafe version of: CmdEncodeVideoKHR

vkCmdEncodeVideoKHR

public static void vkCmdEncodeVideoKHR(org.lwjgl.vulkan.VkCommandBuffer commandBuffer,
 VkVideoEncodeInfoKHR pEncodeInfo)

Launch video encode operations.

C Specification

To launch video encode operations, call:

 void vkCmdEncodeVideoKHR(
     VkCommandBuffer                             commandBuffer,
     const VkVideoEncodeInfoKHR*                 pEncodeInfo);

Description

Each call issues one or more video encode operations. The implicit parameter opCount corresponds to the number of video encode operations issued by the command. After calling this command, the active query index of each active query is incremented by opCount.

Currently each call to this command results in the issue of a single video encode operation.

If the bound video session was created with VIDEO_SESSION_CREATE_INLINE_QUERIES_BIT_KHR and the pNext chain of pEncodeInfo includes a VkVideoInlineQueryInfoKHR structure with its queryPool member specifying a valid VkQueryPool handle, then this command will execute a query for each video encode operation issued by it.

Active Reference Picture Information

• The image subregion within the image subresource referred to by the video picture resource used as the reference picture.
• The DPB slot index the reference picture is associated with.
• The codec-specific reference information related to the reference picture.

Reconstructed Picture Information

• The image subregion within the image subresource referred to by the video picture resource used as the reconstructed picture.
• The DPB slot index to use for picture reconstruction.
• The codec-specific reference information related to the reconstructed picture.

Specifying a valid VkVideoReferenceSlotInfoKHR structure in pEncodeInfo→pSetupReferenceSlot is always required, unless the video session was created with VkVideoSessionCreateInfoKHR::maxDpbSlot equal to zero. However, the DPB slot identified by pEncodeInfo→pSetupReferenceSlot→slotIndex is only activated with the reconstructed picture specified in pEncodeInfo→pSetupReferenceSlot→pPictureResource if reference picture setup is requested according to the codec-specific semantics.

If reconstructed picture information is specified, but reference picture setup is not requested, according to the codec-specific semantics, the contents of the video picture resource corresponding to the reconstructed picture will be undefined after the video encode operation.

Note

Some implementations may always output the reconstructed picture or use it as temporary storage during the video encode operation even when the reconstructed picture is not marked for future reference.

Encode Input Picture Information

• The image subregion within the image subresource referred to by the video picture resource used as the encode input picture.
• The codec-specific picture information related to the encoded picture.

Several limiting values are defined below that are referenced by the relevant valid usage statements of this command.

Let the initial value of each element of the array be 0.
  • If pEncodeInfo→pSetupReferenceSlot is not NULL, then dpbFrameUseCount[i] is incremented by one, where i equals pEncodeInfo→pSetupReferenceSlot→slotIndex.
  • For each element of pEncodeInfo→pReferenceSlots, dpbFrameUseCount[i] is incremented by one, where i equals the slotIndex member of the corresponding element.

  • minCodingBlockExtent.height = (codedExtent.height maxCodingBlockSize.height - 1) / maxCodingBlockSize.height

  • Let StdVideoH265PictureType h265L0PictureTypes[] and StdVideoH265PictureType h265L1PictureTypes[] be the picture types of the reference pictures in the L0 and L1 reference lists, respectively. If pStdPictureInfo→pRefLists specified in the VkVideoEncodeH265PictureInfoKHR structure included in the pEncodeInfo→pNext chain is not NULL, then for each reference index specified in the elements of the pStdPictureInfo→pRefLists→RefPicList0 and pStdPictureInfo→pRefLists→RefPicList1 arrays, if the reference index is not STD_VIDEO_H265_NO_REFERENCE_PICTURE, pStdReferenceInfo→pic_type is added to h265L0PictureTypes or h265L1PictureTypes, respectively, where pStdReferenceInfo is the member of the VkVideoEncodeH265DpbSlotInfoKHR structure included in the pNext chain of the element of pEncodeInfo→pReferenceSlots for which slotIndex equals the reference index in question.
