TuSDK Video Editor 接入说明文档

SDK基础说明

接入示例

// 1.初始化处理环境
[TUPEngine Init:nil];

// 2.创建Video Editor
let editor = TUPVEditor()
let config = TUPVEditor_Config()
config.width = 800
config.height = 800
editor.create(with: config)

// 3.创建Video Clip
let videoConfig = TUPConfig()
videoConfig.setString(videoPath, forKey: TUPVEFileClip_CONFIG_PATH)
let videoClip = TUPVEditorClip(editor.getContext(), withType: TUPVEFileClip_VIDEO_TYPE_NAME)
videoClip.setConfig(videoConfig)

// 4.创建Audio Clip
let audioConfig = TUPConfig()
audioConfig.setString(audioPath, forKey: TUPVEFileClip_CONFIG_PATH)
let audioClip = TUPVEditorClip(editor.getContext(), withType: TUPVEFileClip_AUDIO_TYPE_NAME)
audioClip.setConfig(audioConfig)

// 5.创建视频层
let videoLayer = TUPVEditorClipLayer(forVideo: editor.getContext())
val videoLayerConfig = Config()
videoLayer.setConfig(videoLayerConfig)

// 6.创建音频层
let audioLayer = TUPVEditorClipLayer(forAudio: editor.getContext())
val audioLayerConfig = Config()
audioLayer.setConfig(audioLayerConfig)


// 7.将Clip 添加到对应层内
videoLayer.add(videoClip, at: 100)
audioLayer.add(audioClip, at: 100)

// 8.将对应Layer加入到对应的Composition中
let videoComp = editor.videoComposition()
videoComp.add(videoLayer, at: 100)

let audioComp = editor.audioComposition()
audioComp.add(audioLayer, at: 100)

// 9.初始化播放器
let player = EditorAdapter().player

// 10.设置播放状态与进度回调
player.delegate = self

// 11.启动播放器
player.open()

// 12.初始化渲染View
let displayView = TUPDisplayView()
displayView.frame = CGRect(x: 0, y: 0, width: UIScreen.width(), height: UIScreen.width())
[displayView setup:nil];
// 13.绑定播放器
displayView.attach(player)

// 14.创建Effect
var filterEffectBuilder = TUPVETusdkFilterEffect_PropertyBuilder()
var filterVideoEffect = TUPVEditorEffect(editor.getContext(), withType: TUPVETusdkFilterEffect_TYPE_NAME)

let config = TUPConfig()
config.setString(code, forKey: TUPVETusdkFilterEffect_CONFIG_NAME)
filterVideoEffect.setConfig(config)

filterVideoEffect.setProperty(filterEffectBuilder.makeProperty(), forKey: TUPVETusdkFilterEffect_PROP_PARAM)

// 15.添加Effect
videoClip.effects().add(filterVideoEffect, at: 100)

基础类说明

Config

Config 相关的属性为不可动态调节的属性,Config属性变动时,需要重新对VideoEditor进行重新构建

Config 接口说明
- (instancetype) init;
- (instancetype) initWithImpl:(void*)config;//pulse::Config

// Config*
- (BOOL) unwrap:(void*)config;

- (BOOL) setNumber:(NSNumber*)number forKey:(NSString*)key;
- (NSNumber*) getNumber:(NSString*)key;


- (BOOL) setIntNumber:(NSInteger)number forKey:(NSString*)key;
- (NSInteger) getIntNumber:(NSString*)key;
- (NSInteger) getIntNumber:(NSString*)key or:(NSInteger)val;


- (BOOL) setDoubleNumber:(double)number forKey:(NSString*)key;

Property

Property 相关属性为可动态调节属性,Property属性变动时,会实时生效,不需要重新构建VideoEditor

SDK内各层级只可读属性同样通过Property输出,Property构造由各模块自行实现.用户无需手动构造Property。

Clip作为SDK内的最小单元,负责图片,视频等实例的创建,Clip 类型分别包含 :

  • VideoClip 视频轨道
  • AudioClip 音频轨道
  • ImageClip 图片
  • Text2DClip 文字
  • SilenceClip 静音音频数据

各类型Clip可以通过Config来设置相应的属性,加载对应资源.
