添加FUCamera文件来采集视频，遵循FUCameraDelegate，AgoraVideoSourceProtocol。（Add FUCamera file to collect video. Follow FUCameraDelegate and AgoraVideoSourceProtocol） ``` - (void)didOutputVideoSampleBuffer:(CMSampleBufferRef)sampleBuffer { CVPixelBufferRef pixelBuffer = (CVPixelBufferRef)CMSampleBufferGetImageBuffer(sampleBuffer) ; CVPixelBufferLockBaseAddress(pixelBuffer, 0); [self.beautyManager processAgoraWithPixelBuffer:pixelBuffer]; [self.consumer consumePixelBuffer:pixelBuffer withTimestamp:CMSampleBufferGetPresentationTimeStamp(sampleBuffer) rotation:AgoraVideoRotationNone]; CVPixelBufferUnlockBaseAddress(pixelBuffer, 0); } ```
