Got error as follow
*** Assertion failure in -[GPUImageFilter initWithVertexShaderFromString:fragmentShaderFromString:], /Users/XYZ/Downloads/GPUImage-master/framework/Source/GPUImageFilter.m:94
I have already set as per mention in https://github.com/BradLarson/GPUImage after setting framework path and all other thing wrote following code for testing but getting above error.
GPUImageVideoCamera *videoCamera = [[GPUImageVideoCamera alloc] initWithSessionPreset:AVCaptureSessionPreset640x480 cameraPosition:AVCaptureDevicePositionBack];
videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait;
GPUImageFilter *customFilter = [[GPUImageFilter alloc] initWithFragmentShaderFromFile:@"CustomShader"];
GPUImageView *filteredVideoView = [[GPUImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, viewWidth, viewHeight)];
// Add the view somewhere so it's visible
[videoCamera addTarget:customFilter];
[customFilter addTarget:filteredVideoView];
[videoCamera startCameraCapture];
please help me to solve this...
NSAssert(NO, @"Filter shader link failed");
your link "CustomShader" is wrong. Do you have CustomShader.fsh in your project?
