The ten_packages/extension folder contains the extension modules. Each extension module is a separate Python/Golang/C++ package.
The extension folder name is often the same as the extension module name, while you can also find the extension module name in the manifest.json file under the extension folder. The module name shall be used in the addon property of the property.json file.
Below is a sample structure of the extension folder:
manifest.json: This file contains the metadata of the extension. It includes the extension name, version, properties, and apis (data, audio_frame, video_frame).
property.json: This file contains the default properties of the extension. It is used to define the default configuration of the extension.
extension.py: This file contains the main logic of the extension. It usually contains the core implementation of the extension.
requirements.txt: This file contains the Python dependencies required by the extension. Dependencies specified in this file will be installed automatically when you run task use.
_extension.go: This file contains the main logic of the extension. It usually contains the core implementation of the extension.
go.mod: This file contains the Go module definition. It specifies the module name and the dependencies of the extension.
src/main.cc: This file contains the main logic of the extension. It usually contains the core implementation of the extension.
BUILD.gn: This file contains the build configuration of the extension. It specifies the target name and dependencies of the extension.
