VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT

Initial draft

General Spec cleanup

Added DPB structures

Change the VCL frame encode structure

Added a common Non-VCL Picture Paramarameters structure

Spec and API updates

Rename VkVideoEncodeH264CapabilitiesFlagsEXT to VkVideoEncodeH264CapabilityFlagsEXT and VkVideoEncodeH264CapabilitiesFlagsEXT to VkVideoEncodeH264CapabilityFlagsEXT, following Vulkan naming conventions.

Rate control updates

Align VkVideoEncodeH264VclFrameInfoEXT structure to similar one in VK_EXT_video_encode_h265 extension

Updates to encode capability interface

Relocate Std header version reporting/requesting from this extension to VK_KHR_video_queue extension.

Remove redundant maxPictureSizeInMbs from VkVideoEncodeH264SessionCreateInfoEXT.

Remove the now empty VkVideoEncodeH264SessionCreateInfoEXT.

Add capability flag to report support to use B frame in L1 reference list.

Add capability flag to report support for disabling SPS direct_8x8_inference_flag.

Replace VkVideoEncodeH264RateControlStructureFlagBitsEXT bit enum with VkVideoEncodeH264RateControlStructureEXT enum

Rename VkVideoEncodeH264ProfileEXT to VkVideoEncodeH264ProfileInfoEXT

Rename VkVideoEncodeH264ReferenceListsEXT to VkVideoEncodeH264ReferenceListsInfoEXT

Rename VkVideoEncodeH264EmitPictureParametersEXT to VkVideoEncodeH264EmitPictureParametersInfoEXT

Rename VkVideoEncodeH264NaluSliceEXT to VkVideoEncodeH264NaluSliceInfoEXT

Rename spsStdCount, pSpsStd, ppsStdCount, and pPpsStd to stdSPSCount, pStdSPSs, stdPPSCount, and pStdPPSs, respectively, in VkVideoEncodeH264SessionParametersAddInfoEXT

Rename maxSpsStdCount and maxPpsStdCount to maxStdSPSCount and maxStdPPSCount, respectively, in VkVideoEncodeH264SessionParametersCreateInfoEXT

Removed VkVideoEncodeH264EmitPictureParametersInfoEXT

Changed member types in VkVideoEncodeH264CapabilitiesEXT and VkVideoEncodeH264ReferenceListsInfoEXT from uint8_t to uint32_t

Changed the type of VkVideoEncodeH264RateControlInfoEXT::temporalLayerCount and VkVideoEncodeH264RateControlLayerInfoEXT::temporalLayerId from uint8_t to uint32_t

Removed VkVideoEncodeH264InputModeFlagsEXT and VkVideoEncodeH264OutputModeFlagsEXT as we only support frame-in-frame-out mode for now

Rename pCurrentPictureInfo in VkVideoEncodeH264VclFrameInfoEXT to pStdPictureInfo

Rename pSliceHeaderStd in VkVideoEncodeH264NaluSliceInfoEXT to pStdSliceHeader

Rename pReferenceFinalLists in VkVideoEncodeH264VclFrameInfoEXT and VkVideoEncodeH264NaluSliceInfoEXT to pStdReferenceFinalLists

Removed the slotIndex member of VkVideoEncodeH264DpbSlotInfoEXT and changed it to be chained to VkVideoReferenceSlotInfoKHR

Replaced VkVideoEncodeH264ReferenceListsInfoEXT with the new Video Std header structure StdVideoEncodeH264ReferenceLists that also includes data previously part of the now removed StdVideoEncodeH264RefMemMgmtCtrlOperations structure

Added new capability flag VK_VIDEO_ENCODE_H264_CAPABILITY_DIFFERENT_REFERENCE_FINAL_LISTS_BIT_EXT

Renamed VkVideoEncodeH264VclFrameInfoEXT to VkVideoEncodeH264PictureInfoEXT

Added VkVideoEncodeH264PictureInfoEXT::generatePrefixNalu and VK_VIDEO_ENCODE_H264_CAPABILITY_GENERATE_PREFIX_NALU_BIT_EXT to enable the generation of H.264 prefix NALUs when supported by the implementation

Removed VkVideoEncodeH264RateControlLayerInfoEXT::temporalLayerId

Added expectDyadicTemporalLayerPattern capability

Added the VkVideoEncodeH264SessionParametersGetInfoEXT structure to identify the H.264 parameter sets to retrieve encoded parameter data for, and the VkVideoEncodeH264SessionParametersFeedbackInfoEXT structure to retrieve H.264 parameter set override information when using the new vkGetEncodedVideoSessionParametersKHR command

Added VkVideoEncodeH264NaluSliceInfoEXT::constantQp to specify per-slice constant QP when rate control mode is VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DISABLED_BIT_KHR

Added VkVideoEncodeH264QualityLevelPropertiesEXT for retrieving H.264 specific quality level recommendations

Replaced VkVideoEncodeH264RateControlStructureEXT enum with the flags type VkVideoEncodeH264RateControlFlagsEXT and bits defined in VkVideoEncodeH264RateControlFlagBitsEXT and added HRD compliance flag

Removed useInitialRcQp and initialRcQp members of VkVideoEncodeH264RateControlLayerInfoEXT

Added prefersGopRemainingFrames and requiresGopRemainingFrames, and the new VkVideoEncodeH264GopRemainingFrameInfoEXT structure to allow specifying remaining frames of each type in the rate control GOP

Added maxTemporalLayers, maxQp, and minQp capabilities

Added maxLevelIdc capability and new VkVideoEncodeH264SessionCreateInfoEXT structure to specify upper bounds on the H.264 level of the produced video bitstream
