SDK 集成

1. 集成腾讯特效 SDK，请参考 TRTC SDK 集成腾讯特效。
2. 本文档说明在 TRTC SDK 项目中集成和使用 TEBeautyKit 库。
3. 参考 demo。

SDK 使用

步骤一：集成 TEBeautyKit

1. 下载并解压 TEBeautyKit。
2. 把 TEBeautyKit 文件夹拷贝到自己的工程中，和 podfile 同级目录。
3. 编辑 podfile 文件，添加下面的代码：
  pod 'TEBeautyKit',:path => 'TEBeautyKit/TEBeautyKit.podspec'

步骤二：鉴权

[TEBeautyKit setTELicense:@"your license" key:@"your key" completion:^(NSInteger authresult, NSString * _Nullable errorMsg) {
  NSLog(@"----------result: %zd  %@",authresult,errorMsg);
}];

步骤三：配置美颜素材路径

如果 json 文件中配置的素材是本地的，需要将美颜素材添加到工程中。
- (void)initBeautyJson{
    NSString *resourcePath = [[NSBundle mainBundle]
    pathForResource:@"TEBeautyKitResources" ofType:@"bundle"];
    NSBundle *bundle = [NSBundle bundleWithPath:resourcePath];
    [[TEUIConfig shareInstance] setTEPanelViewRes:[bundle pathForResource:@"beauty_S1" ofType:@"json"] 
    beautyBody:[bundle pathForResource:@"beauty_body" ofType:@"json"] 
    lut:[bundle pathForResource:@"lut" ofType:@"json"] 
    motion:[bundle pathForResource:@"motions" ofType:@"json"] 
    makeup:[bundle pathForResource:@"makeup" ofType:@"json"] 
    segmentation:[bundle pathForResource:@"segmentation" ofType:@"json"]];
}

步骤四：初始化并添加 TEPanelView

-(TEPanelView *)tePanelView{
    if (!_tePanelView) {
        _tePanelView = [[TEPanelView alloc] init:nil comboType:nil];
        _tePanelView.delegate = self;
    }
    return _tePanelView;
}
[self.view addSubview:self.tePanelView];
[self.tePanelView mas_makeConstraints:^(MASConstraintMaker *make) {
    make.width.mas_equalTo(self.view);
    make.centerX.mas_equalTo(self.view);        
    make.height.mas_equalTo(250);
    make.bottom.mas_equalTo(self.view.mas_bottom);
}];

步骤五：设置视频数据回调

[self.trtcCloud setLocalVideoProcessDelegete:self pixelFormat:TRTCVideoPixelFormat_Texture_2D bufferType:TRTCVideoBufferType_Texture];

步骤六：在视频帧回调接口中创建 XMagic 对象和处理视频数据

-(void)initXMagic{
    __weak __typeof(self)weakSelf = self;
    [TEBeautyKit create:^(XMagic * _Nullable api) {
        __strong typeof(self) strongSelf = weakSelf;
        strongSelf.xMagicKit = api;
        [strongSelf.teBeautyKit setXMagicApi:api];
        strongSelf.tePanelView.teBeautyKit = strongSelf.teBeautyKit;
        [strongSelf.teBeautyKit setTePanelView:strongSelf.tePanelView];
        [strongSelf.teBeautyKit setLogLevel:YT_SDK_ERROR_LEVEL];
        strongSelf.tePanelView.beautyKitApi = api;
        [strongSelf.xMagicKit registerSDKEventListener:strongSelf];
    }];
}
#pragma mark - TRTCVideoFrameDelegate
- (uint32_t)onProcessVideoFrame:(TRTCVideoFrame *_Nonnull)srcFrame dstFrame:(TRTCVideoFrame *_Nonnull)dstFrame {
    if(!_xMagicKit){
        [self initXMagic];
    }
    YTProcessOutput *output = [self.teBeautyKit processTexture:srcFrame.textureId 
    textureWidth:srcFrame.width textureHeight:srcFrame.height 
    withOrigin:YtLightImageOriginTopLeft withOrientation:YtLightCameraRotation0];
    dstFrame.textureId = output.textureData.texture;
    return 0;
}

步骤七：销毁美颜

- (void)destroyXMagic{
    [self.xMagicKit clearListeners];
    [self.xMagicKit deinit];
    self.xMagicKit = nil;
}
