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 indicates that the implementation supports the use of VkVideoEncodeInfoKHR::precedingExternallyEncodedBytes.
• VIDEO_ENCODE_CAPABILITY_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_DETECTION_BIT_KHR indicates 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.

public static final int VK_VIDEO_ENCODE_CAPABILITY_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_DETECTION_BIT_KHR

VkVideoEncodeCapabilityFlagBitsKHR - Video encode capability flags

Description

• VIDEO_ENCODE_CAPABILITY_PRECEDING_EXTERNALLY_ENCODED_BYTES_BIT_KHR indicates that the implementation supports the use of VkVideoEncodeInfoKHR::precedingExternallyEncodedBytes.
• VIDEO_ENCODE_CAPABILITY_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_DETECTION_BIT_KHR indicates 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.

• physicalDevice must be a valid VkPhysicalDevice handle
• pQualityLevelInfo must be a valid pointer to a valid VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR structure
• pQualityLevelProperties must be a valid pointer to a VkVideoEncodeQualityLevelPropertiesKHR structure

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY
• ERROR_VIDEO_PROFILE_OPERATION_NOT_SUPPORTED_KHR
• ERROR_VIDEO_PROFILE_FORMAT_NOT_SUPPORTED_KHR
• ERROR_VIDEO_PICTURE_LAYOUT_NOT_SUPPORTED_KHR
• ERROR_VIDEO_PROFILE_CODEC_NOT_SUPPORTED_KHR

pQualityLevelProperties - a pointer to a VkVideoEncodeQualityLevelPropertiesKHR structure in which the properties are returned.

nvkGetEncodedVideoSessionParametersKHR

public static int nvkGetEncodedVideoSessionParametersKHR(org.lwjgl.vulkan.VkDevice device,
 long pVideoSessionParametersInfo,
 long pFeedbackInfo,
 long pDataSize,
 long pData)

Unsafe version of: GetEncodedVideoSessionParametersKHR

Parameters:

pDataSize - a pointer to a size_t value related to the amount of encode parameter data returned, as described below.

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.

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• pVideoSessionParametersInfo must be a valid pointer to a valid VkVideoEncodeSessionParametersGetInfoKHR structure
• If pFeedbackInfo is not NULL, pFeedbackInfo must be a valid pointer to a VkVideoEncodeSessionParametersFeedbackInfoKHR structure
• pDataSize must be a valid pointer to a size_t value
• If the value referenced by pDataSize is not 0, and pData is not NULL, pData must be a valid pointer to an array of pDataSize bytes

Return Codes

On success, this command returns

• SUCCESS
• INCOMPLETE

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

Unsafe version of: CmdEncodeVideoKHR

vkCmdEncodeVideoKHR

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

Encode operation for bitstream generation.

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.

Valid Usage

• For each active query, the active query index corresponding to the query type of that query plus opCount must be less than or equal to the last activatable query index corresponding to the query type of that query plus one

Valid Usage (Implicit)

• commandBuffer must be a valid VkCommandBuffer handle
• pEncodeInfo must be a valid pointer to a valid VkVideoEncodeInfoKHR structure
• commandBuffer must be in the recording state
• The VkCommandPool that commandBuffer was allocated from must support encode operations
• This command must only be called outside of a render pass instance
• This command must only be called inside of a video coding scope
• commandBuffer must be a primary VkCommandBuffer

Host Synchronization

• Host access to commandBuffer must be externally synchronized
• Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
