Introduction

Huawei Video Editor Kit (Video Editor Kit) provided by Huawei to quickly build video editing capabilities. It provides two integration modes.

• Video editor UI SDK, which provides product-level UIs and easy integration.

• Video editor atomic capability SDK, which provides hundreds of underlying capability interfaces, including multiple AI algorithm capability interfaces, which can be flexibly selected based on service scenarios.

• Screen recorder demo provide basic usage of screen recording. There are functions demonstrating usage of start/stop recording and setting configuration.

• Template creation SDK, which provides the capability of creating and uploading templates.

Both modes provide one-stop video editing capabilities, such as import, editing, rendering, export, and media resource management. These two modes provide high-performance, easy-to-use, and highly compatible interfaces, helping you easily build applications.

Running Procedure

• Clone the code base to the local host.

• If you haven't already registered as a developer, register and create an app on AppGalleryConnect.

• Obtain the agconnect-services.json file from HUAWEI Developers.

• Place the agconnect-services.json file in the root directory of the demo.

• If you need to use cloud-side service capabilities, you need to use the api_key value in agconnect-services.json to call MediaApplication.getInstance().setApiKey(String apiKey) during application initialization.

• Compile and run on an Android device or emulator.

Note:

The package name in this project cannot be used to apply for agconnect-services.json. You can use a customized package name to apply for agconnect-services.json. You only need to change applicationId in application-level build.gradle to the same package name as the applied agconnect-services.json to experience Video Editor Kit services.

Supported Environment

Android SDK 24 or later and JDK 1.8 or later are recommended.

Code indexes for key functions

|-- HomeActivity: App home page, which can be redirected to the video creation page (MainActivity) and the open, independent AI capabilities.
	|-- Entries to AI capabilities on the home screen:
		|-- faceReenact(String imagePath): moving picture
		|-- faceSmile(String imagePath): auto-smile
		|-- aiColor(String filePath): AI color
		|-- timeLapse(String imagePath): auto-timelapse
		|-- videoSelection(String videoPath): highlight
		|-- objectSeg(String photoPath): object segmentation
		|-- headSeg(String photoPath): head segmentation
		|-- Color hair. **HairDyeingFragment** is launched. After a hair color is selected and successfully downloaded, **hairDyeing(Bitmap colormapBitmap)** is called for processing.
		|-- Beauty. **CameraActivity** and **CameraPreviewFragment** are launched.

|-- MainActivity: video creation page, which can be switched to the editing screen (**ClipFragment**) and template home screen (**TemplateHomeFragment**).
|-- MediaPickActivity: material selection screen. When there is a need to select materials from the album, this screen will be launched.
|-- VideoClipsActivity: video editing screen, which can be entered via material import for creation or a draft. The upper part of the screen is the preview area, the middle part contains playback operations and the timeline, and the lower part is the two-level menu area.
|-- MaterialEditFragment: preview area, where a material can be edited. It is the entry to the zooming in or out using two fingers, dragging, rotating, and other operations on the material selected on the preview area.
|-- MenuClickManager: manager for menu clicks. The menu click event on the video editing screen is processed in the **handlerClickEvent** method. Each click event launches a corresponding fragment. All fragments inherit the **BaseFragment** abstract class, implementing the following methods: **initView**, **initObject**, **initData**, and **initEvent**. **initView** initializes the layout and component. The listener for the component is created in the **initEvent** method, to respond to the click event in each fragment and conduct relevant service logic processing.
