Integrating With MLVB SDK

This documentation explains integrating and using the TEBeautyKit library in the Mobile Live Video BroadcastingStreaming (MLVB) SDK project. 
Refer to LIVE_Adapter_Example.
Integration Steps
1. (Optional) Integrate TELiveAdapter. The TELiveAdapter.framework is used to receive video callbacks from the MLVB SDK, process them internally using the beauty filter SDK, and then return them to the MLVB SDK. If you need to perform custom processing on the video stream, you can skip this step.
﻿
2. Integration TEBeautyKit，Edit the Podfile and append the following code snippet and execution pod install.
# Replace S1-07 with the package you purchased
pod 'TEBeautyKit/S1-07', :podspec => 'https://mediacloud-76607.gzc.vod.tencent-cloud.com/TencentEffect/iOS/TEBeautyKit/latest/TEBeautyKit.podspec'
3. Integration Panel Resources，download the resource package and incorporate it into your main project. The contents can be found in the appendix.
4. Integration Effect Resources.
Usage Guide
Step 1. Authenticate
After the application is launched, a beauty filter authentication must be performed to enable the normal use of beauty features. See the authentication error code﻿
[TEBeautyKit setTELicense:@"your license" key:@"your key" completion:^(NSInteger authresult, NSString * _Nullable errorMsg) {
  NSLog(@"----------result: %zd  %@",authresult,errorMsg);
}];
Step 2. Configuration Panel Resource Path
The beauty data and icon assets on the beauty panel are available in beauty_panel.zip. As per the API documentation, you may pass the corresponding JSON file path and customize the settings according to your specific requirements.  
- (void)configPanel {
    NSBundle *bundle = [NSBundle mainBundle];
    NSString *beautyJsonPath = [bundle pathForResource:@"beauty" ofType:@"json"]; //Beauty
    NSString *lutJsonPath = [bundle pathForResource:@"lut" ofType:@"json"]; //filter
    NSString *motion2dJsonPath = [bundle pathForResource:@"motion_2d" ofType:@"json"]; //2D stickers
    NSMutableArray *resArray = [[NSMutableArray alloc] init];
    [resArray addObject:@{TEUI_BEAUTY : beautyJsonPath}];
    [resArray addObject:@{TEUI_LUT : lutJsonPath}];
    [resArray addObject:@{TEUI_MOTION_2D : motion2dJsonPath}];
    /// Set up resources
    [[TEUIConfig shareInstance] setTEPanelViewResources:resArray];
}
Step 3. Initialize and incorporate TEPanelView
TEPanelView is a custom panel view used to display the data configured in Step 2.
- (void)addPanelView {
    TEPanelView *tePanelView = [[TEPanelView alloc] init];
    tePanelView.delegate = self;
    [self.view addSubview:tePanelView];
    [tePanelView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.width.bottom.mas_equalTo(self.view);
        make.left.right.mas_equalTo(self.view);
        make.height.mas_equalTo(230 + self.view.safeAreaInsets.bottom);
    }];
}
If TELiveAdapter is not integrated, please refer directly to step 7.
Step 4: Adapter Binding for Beautification
/// create adapter
- (TEBeautyLiveAdapter *)liveAdapter {
    if (!_liveAdapter) {
        _liveAdapter = [[TEBeautyLiveAdapter alloc] init];
    }
    return _liveAdapter;
}
/// bind
__weak __typeof(self)weakSelf = self;
[self.liveAdapter bind:self.livePusher onCreatedXmagicApi:^(XMagic * _Nullable xmagicApi) {
    __strong typeof(self) strongSelf = weakSelf;
    strongSelf.teBeautyKit.xmagicApi = xmagicApi;
    [strongSelf.teBeautyKit setLogLevel:YT_SDK_ERROR_LEVEL];
    strongSelf.tePanelView.teBeautyKit = strongSelf.teBeautyKit;
    [strongSelf.tePanelView setDefaultBeauty];
  } onDestroyXmagicApi:^{
     __strong typeof(self) strongSelf = weakSelf;
     [strongSelf.teBeautyKit onDestroy];
     strongSelf.teBeautyKit = nil;
}];
Step 5: Parameter Change Notification Adapter
/// Notify the Adapter of the Front and Rear Cameras: Whether to Encode a Mirror Image
[self.liveAdapter notifyCameraChanged:self.isFrontCamera isEncoderMirror:self.isEncoderMirror];
/// Notify the Adapter of Screen Orientation Changes
[self.liveAdapter setDeviceOrientation:orientation];
Step 6: Unbinding the Adapter
 [self.liveAdapter unbind];
 self.liveAdapter = nil;
Step 7: TELiveAdapter is not integrated.
Listen for MLVB video callbacks, process the beauty effects within the callback, and then return the processed video to MLVB.
1. Initialization
- (void)initXMagic {
    __weak __typeof(self)weakSelf = self;
    [TEBeautyKit createXMagic:EFFECT_MODE_PRO onInitListener:^(TEBeautyKit * _Nullable beautyKit) {
        __strong typeof(self)strongSelf = weakSelf;
        strongSelf.teBeautyKit = beautyKit;
        strongSelf.tePanelView.teBeautyKit = strongSelf.teBeautyKit;
        [strongSelf.tePanelView setDefaultBeauty];
        [strongSelf.teBeautyKit setLogLevel:YT_SDK_ERROR_LEVEL];
        [strongSelf.teBeautyKit registerSDKEventListener:strongSelf];
    }];
}
2. Processing video data
- (void)onProcessVideoFrame:(V2TXLiveVideoFrame *)srcFrame dstFrame:(V2TXLiveVideoFrame *)dstFrame {
    YTProcessOutput *output = [self.teBeautyKit processTexture:srcFrame.textureId
                                                  textureWidth:srcFrame.width
                                                 textureHeight:srcFrame.height
                                                    withOrigin:YtLightImageOriginTopLeft
                                               withOrientation:YtLightCameraRotation0];
    dstFrame.textureId = output.textureData.texture;
}
3. Destroy Beauty Filter
- (void)destroyXMagic {
   [self.teBeautyKit onDestroy];
   self.teBeautyKit = nil;
}
