I have created video using AVFoundation and now I want to edit it via GPUImage framework. I have set all the setting as per mention here . After seeing his example of "SimpleVideoFileFilter" I have just copied his code and replace my Assets URL for Video. Here is the code. movieFile = [[GPUImageMovie alloc] initWithURL:player.contentURL]; pixellateFilter = [[GPUImagePixellateFilter alloc] init]; [movieFile addTarget:pixellateFilter]; NSString *pathToMovie = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Movie.m4v"]; unlink([pathToMovie UTF8String]); NSURL *movieURL = [NSURL

In my project, I apply colors to an image then after a second I am applying a Kuwahara filter to it, for watercolor effect, but the thing is it takes time to apply the filter and if I change the colors too much the app eventually crashes due to memory issues. Can anyone help me how to use the filter in the best manner. Thanks CODE @objc func fillColorButtonTapped(_ sender : UIButton){ self.processingModel.isImageMixedColor = false if let popoverController = self.mkColorPicker.popoverPresentationController{ popoverController.delegate = self.mkColorPicker popoverController

I am using GPUImageMovie with initWithPlayerItem and its not starting the movie file on startProcessing. It was working fine with initWithUrl but I need playback controls for the player as told in this thread. I am using the following code -(void)loadVideo { _playerItem = [[AVPlayerItem alloc]initWithURL:movieURL]; _player = [AVPlayer playerWithPlayerItem:_playerItem]; movieFile = [[GPUImageMovie alloc] initWithPlayerItem:_playerItem]; movieFile.runBenchmark = YES; movieFile.playAtActualSpeed = YES; filter = [[TSFilter alloc] init]; _movieView = [[GPUImageView alloc] initWithFrame:self.view

I'm using two third party tools in my project. One is "The Amazing Audio Engine" . I use this for audio filters. The other is GPUImage, or more specifically, GPUImageMovieWriter . When I record videos, I merge an audio recording with the video. This works fine. However, sometimes I do not use The Amazing Audio Engine and just record a normal video using GPUImageMovieWriter. The problem is, even just after initializing The Amazing Audio Engine, the video has only a fraction of a second of audio at the beginning, and then the audio is gone. + (STAudioManager *)sharedManager { static

GPUImage是iOS上一个基于OpenGL进行图像处理的开源框架，内置大量滤镜，架构灵活，可以在其基础上很轻松地实现各种图像处理功能。 GPUImgae特性 1，丰富的输入组件 摄像头、图片、视频、OpenGL纹理、二进制数据、UIElement(UIView, CALayer) 2，大量现成的内置滤镜（4大类） 1). 颜色类（亮度、色度、饱和度、对比度、曲线、白平衡...） 2). 图像类（仿射变换、裁剪、高斯模糊、毛玻璃效果...） 3). 颜色混合类（差异混合、alpha混合、遮罩混合...） 4). 效果类（像素化、素描效果、压花效果、球形玻璃效果...） 3，丰富的输出组件 UIView、视频文件、GPU纹理、二进制数据 4，灵活的滤镜链 滤镜效果之间可以相互串联、并联，调用管理相当灵活。 5，接口易用 滤镜和OpenGL资源的创建及使用都做了统一的封装，简单易用，并且内置了一个cache模块实现了framebuffer的复用。 6，线程管理 OpenGLContext不是多线程安全的，GPUImage创建了专门的contextQueue，所有的滤镜都会扔到统一的线程中处理。 7，轻松实现自定义滤镜效果 继承GPUImageFilter自动获得上面全部特性，无需关注上下文的环境搭建，专注于效果的核心算法实现即可。 滤镜基本原理

I've gone through the obj-c GPUImage framework, and as per the example in the documentation, I added the following snippet with intention to display filtered live video: CGRect mainScreenFrame = [[UIScreen mainScreen] applicationFrame]; GPUImageVideoCamera *videoCamera = [[GPUImageVideoCamera alloc] initWithSessionPreset:AVCaptureSessionPreset640x480 cameraPosition:AVCaptureDevicePositionBack]; videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait; GPUImageFilter *customFilter = [[GPUImageFilter alloc] initWithFragmentShaderFromFile:@"PositionColor"]; GPUImageView
