- 設置代理對象（set the proxy object） ``` TXVideoCustomProcessDelegate ``` ``` TXLivePush *pusher = [[TXLivePush alloc] initWithConfig:config]; ``` ``` pusher.videoProcessDelegate = self; ``` - 在代理方法即視頻渲染方法中賦值，如下所示（Assign values in the proxy method, i.e. video rendering method, as shown below）： ``` - (GLuint)onPreProcessTexture:(GLuint)texture width:(CGFloat)width height:(CGFloat)height{ int newTexture = [self.beautyManager getTexrureProcessWithTexture:texture width:width height:height]; return newTexture; } ``` Tip： 1. 如果是開啟直播有鏡像效果的話，設置(if the live broadcast is enabled and has the image effect,set) ``` [_txLivePublisher setMirror:YES]; ``` 2. 如果調用騰訊的美顏，則需要實現代理方法，具體如下（If you call Tencent's beauty, you need to implement the proxy method, as follows:） ``` #pragma mark - MHMenuView Delegate - (void)beautyEffectWithLevel:(NSInteger)beauty whitenessLevel:(NSInteger)white ruddinessLevel:(NSInteger)ruddiness { TXBeautyManager \*manager = [_pusher getBeautyManager]; [manager setBeautyStyle:TXBeautyStyleSmooth]; [manager setBeautyLevel:beauty]; [manager setWhitenessLevel:white]; [manager setRuddyLevel:ruddiness]; } ``` 1. 如果需要適配性能較低手機，需要更換成以下調用方式（ If you need to adapt to a mobile phone with low performance, you need to replace it with the following calling method） 1\. ViewController add BOOL \_needScale; 2\. ViewController add checkDeivice method： ``` - (void)checkDevice{ /*獲取當前機型，判斷是否為 iPhone7 及以上*/ struct utsname systemInfo; uname(&systemInfo); NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; NSArray *symbols = [platform componentsSeparatedByString:@","]; if (symbols.count > 0){ NSCharacterSet *characterSet = [[NSCharacterSet decimalDigitCharacterSet] invertedSet]; NSInteger number = [[[symbols[0] componentsSeparatedByCharactersInSet:characterSet] componentsJoinedByString:@""] integerValue]; //iPhone9,1 -> iPhone 7 if (number >= 9){ _needScale = NO; }else{ _needScale = YES; } } } ``` 3.在回調中判斷是否需要縮放（Determine whether scaling is required in the callback） ``` -(GLuint)onPreProcessTexture:(GLuint)texture width:(CGFloat)width height:(CGFloat)height{ GLuint newTexture = texture; if (_needScale){ newTexture = [_beautyManager processWithTexture:texture width:width height:height scale:0.75]; }else{ [self.beautyManager processWithTexture:texture width:width height:height]; } return newTexture ; } ```
