# vkCmdEncodeVideoKHR(3) Manual Page

## Name

vkCmdEncodeVideoKHR - Launch video encode operations

## C Specification

To launch video encode operations, call:

    // Provided by VK_KHR_video_encode_queue
    void vkCmdEncodeVideoKHR(
        VkCommandBuffer                             commandBuffer,
        const VkVideoEncodeInfoKHR*                 pEncodeInfo);

## Parameters

- `commandBuffer` is the command buffer in which to record the command.

- `pEncodeInfo` is a pointer to a VkVideoEncodeInfoKHR structure specifying the parameters of the video encode operations.

## 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 VK_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 list of active reference pictures used by a video encode operation is a list of image subregions used as the source of reference picture data and related parameters, and is derived from the VkVideoReferenceSlotInfoKHR structures provided as the elements of the `pEncodeInfo->pReferenceSlots` array. For each element of `pEncodeInfo->pReferenceSlots`, one or more elements are added to the active reference picture list, as defined by the codec-specific semantics. Each element of this list contains the following 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

  Information related to the optional reconstructed picture used by a video encode operation is derived from the VkVideoReferenceSlotInfoKHR structure pointed to by `pEncodeInfo->pSetupReferenceSlot`, if not `NULL`, as defined by the codec-specific semantics, and consists of the following:

  - 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::`maxDpbSlots` 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

  Information related to the encode input picture used by a video encode operation is derived from `pEncodeInfo->srcPictureResource` and any codec-specific parameters provided in the `pEncodeInfo->pNext` chain, as defined by the codec-specific semantics, and consists of the following:

  - 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 `uint32_t activeReferencePictureCount` be the size of the list of active reference pictures used by the video encode operation. Unless otherwise defined, `activeReferencePictureCount` is set to the value of `pEncodeInfo->referenceSlotCount`.

- Let `VkOffset2D codedOffsetGranularity` be the minimum alignment requirement for the coded offset of video picture resources. Unless otherwise defined, the value of the `x` and `y` members of `codedOffsetGranularity` are `0`.

- Let `uint32_t dpbFrameUseCount[]` be an array of size `maxDpbSlots`, where `maxDpbSlots` is the VkVideoSessionCreateInfoKHR::`maxDpbSlots` the bound video session was created with, with each element indicating the number of times a frame associated with the corresponding DPB slot index is referred to by the video coding operation. 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.

- If there is a bound video session parameters object created with VK_VIDEO_SESSION_PARAMETERS_CREATE_QUANTIZATION_MAP_COMPATIBLE_BIT_KHR, then let `VkExtent2D quantizationMapTexelSize` be the quantization map texel size the bound video session parameters object was created with.

- Let `VkExtent2D maxCodingBlockSize` be the maximum codec-specific coding block size that may be used by the video encode operation.

  - If the bound video session object was created with an H.264 encode profile, then let `maxCodingBlockSize` be equal to the size of an H.264 macroblock, i.e. `{16,16}`.

  - If the bound video session object was created with an H.265 encode profile, then let `maxCodingBlockSize` be equal to the maximum H.265 coding block size that may be used by the video encode operation derived as the maximum of the CTB sizes corresponding to the VkVideoEncodeH265CtbSizeFlagBitsKHR bits set in VkVideoEncodeH265CapabilitiesKHR::`ctbSizes`, as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR for the video profile the bound video session was created with.

  - If the bound video session object was created with an AV1 encode profile, then let `maxCodingBlockSize` be equal to the maximum AV1 superblock size that may be used by the video encode operation derived as the maximum of the superblock sizes corresponding to the VkVideoEncodeAV1SuperblockSizeFlagBitsKHR bits set in VkVideoEncodeAV1CapabilitiesKHR::`superblockSizes`, as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR for the video profile the bound video session was created with.

  - Otherwise, `maxCodingBlockSize` is undefined.

- If `maxCodingBlockSize` is defined, then let `VkExtent2D minCodingBlockExtent` be the coded extent of the encode input picture expressed in terms of codec-specific coding blocks, assuming the maximum size of such coding blocks, as defined by `maxCodingBlockSize`, calculated from the value of the `codedExtent` member of `pEncodeInfo->srcPictureResource` as follows:

  - `minCodingBlockExtent.width` = (`codedExtent.width`
    `maxCodingBlockSize.width` - 1) / `maxCodingBlockSize.width`

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

- If the bound video session object was created with an H.264 encode profile, then:

  - Let `StdVideoH264PictureType h264PictureType` be the picture type of the encoded picture set to the value of `pStdPictureInfo->primary_pic_type` specified in the VkVideoEncodeH264PictureInfoKHR structure included in the `pEncodeInfo->pNext` chain.

  - Let `StdVideoH264PictureType h264L0PictureTypes[]` and `StdVideoH264PictureType h264L1PictureTypes[]` be the picture types of the reference pictures in the L0 and L1 reference lists, respectively. If `pStdPictureInfo->pRefLists` specified in the VkVideoEncodeH264PictureInfoKHR 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_H264_NO_REFERENCE_PICTURE`, `pStdReferenceInfo->primary_pic_type` is added to `h264L0PictureTypes` or `h264L1PictureTypes`, respectively, where `pStdReferenceInfo` is the member of the VkVideoEncodeH264DpbSlotInfoKHR structure included in the `pNext` chain of the element of `pEncodeInfo->pReferenceSlots` for which `slotIndex` equals the reference index in question.

- If the bound video session was created with the video codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_KHR and with the intra refresh mode VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_PER_PICTURE_PARTITION_BIT_KHR, `pEncodeInfo->flags` includes VK_VIDEO_ENCODE_INTRA_REFRESH_BIT_KHR, and the `pNext` chain of `pEncodeInfo` includes a VkVideoEncodeIntraRefreshInfoKHR structure, then let `uint32_t intraRefreshH264SliceIndex` be the intra refresh index specified in VkVideoEncodeIntraRefreshInfoKHR::`intraRefreshIndex`. Otherwise `intraRefreshH264SliceIndex` is not defined.

- If the bound video session object was created with an H.265 encode profile, then:

  - Let `StdVideoH265PictureType h265PictureType` be the picture type of the encoded picture set to the value of `pStdPictureInfo->pic_type` specified in the VkVideoEncodeH265PictureInfoKHR structure included in the `pEncodeInfo->pNext` chain.

  - 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.

- If the bound video session was created with the video codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_KHR and with the intra refresh mode VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_PER_PICTURE_PARTITION_BIT_KHR, `pEncodeInfo->flags` includes VK_VIDEO_ENCODE_INTRA_REFRESH_BIT_KHR, and the `pNext` chain of `pEncodeInfo` includes a VkVideoEncodeIntraRefreshInfoKHR structure, then let `uint32_t intraRefreshH265SliceSegmentIndex` be the intra refresh index specified in VkVideoEncodeIntraRefreshInfoKHR::`intraRefreshIndex`. Otherwise `intraRefreshH265SliceSegmentIndex` is not defined.

- If the bound video session object was created with an AV1 encode profile, then:

  - If the `primaryReferenceCdfOnly` member of the VkVideoEncodeAV1PictureInfoKHR structure included in the `pEncodeInfo->pNext` chain is set to VK_TRUE, then let `int32_t cdfOnlyReferenceIndex` be the value of VkVideoEncodeAV1PictureInfoKHR::`pStdPictureInfo->primary_ref_frame`.

  - Otherwise let `int32_t cdfOnlyReferenceIndex` be `-1`.
