I. Overview
Add a PipeLine to realize two Raw inputs and one Raw output.
2. Introduction
PipeLine to add: SWMFMergeRawTwo2One
- Contains 1 memcpy node,
- This node is used to convert 2 raw buffer input inputs into 1 raw buffer output output
3. Add
3.1 Add a pipeline xml under the corresponding Usecase
Place the pipline file in the vendor\qcom\proprietary\chi-cdk\oem\qcom\topology\usecase\components\usecases\UsecaseZSL\pipelines\ directory: camxSWMFMergeRawTwo2One.xml
3.2 Fill the pipeline xml file
Populate camxSWMFMergeRawTwo2One.xml
- (1).SWMFMergeRawTwo2One //PipelineName is unique
- (2). Link all Nodes that need to be linked in NodesList //List all nodes required by the pipeline in
3.3 Modify NodesList:
- NodeId: External customized Node uses NodeId 255 (such as the algorithm Node added by yourself)
- NodePropertyId: 1 is customized Lib
- NodePropertyValue: fill in chi node lib name
The relevant definitions of NodeProperty can be found in vendor\qcom\proprietary\chi-cdk\api\common\chi.h
3.4 Modify PortLinkages
PortLinkages: link list of input target, chi/camx Node and output target
- SourceBuffer：NodeId 4
- SinkBuffer：NodeId 2
The definitions of all software software and hardware NodeId can be found in the vendor\qcom\proprietary\camx\src\core\Camxhwdefs.h file
Source Target：
- TARGET_BUFFER_RAW_IN0
- TARGET_BUFFER_RAW_IN1
Different NodeInstanceId needs to be filled in
3.5 CamxInclude adds a reference to pipeline
In the corresponding Usecase xml file, use CamxInclude to add a reference to the pipeline
vendor\qcom\proprietary\chi-cdk\oem\qcom\topology\usecase\components\usecases\usecasezsl\camxUsecaseZSL.xml
3.6 Add a new target (TARGET_BUFFER_RAW_OUT2) to the pipeline
Add a new target definition for the pipeline in camxUsecaseZSL.xml
3.7 Update TargetStreamMap in the vendor\qcom\proprietary\chi\cdk\core\chifeature2\Chifeature2utils.h file
3.8 Add pipeline ID to ChiUseCase
This pipeline ID must be consistent with the pipeline name
\chi-cdk\core\chiusecase\chxadvancedcamerausecase.cpp
3.9 Add pipeline id
3.10 Add pipeline type
添加pipeline type：\chi-cdk\core\chiframework\chxfeature.h
4. Use
4.1 Using pipeline in Feature of Feature2 architecture
Add pipeline in ChiFeature2PipelineDescriptor array
The target name of the feature target descriptor must be consistent with the target name in the pipeline xml file
