GPUImage - CVPixelBufferCreate -6661出错

Question

您好我正在尝试使用新的GPUImage设置编辑单个图像，但我遇到了以下错误。

2014-07-06 11:52:46.966 App[4314:9d07] *** Assertion failure in -[GPUImageFramebuffer generateFramebuffer],   /Users/Desktop/Apps/App/App/framework/Source/GPUImageFramebuffer.m:156

GPUImagePicture *lookupImageSource = [[GPUImagePicture alloc] initWithImage:[UIImage imageNamed:@"BigApple1.png"]];

    GPUImageLookupFilter * filterLookup = [[GPUImageLookupFilter alloc] init];

    [stillImageSource addTarget:filterLookup];
    [lookupImageSource addTarget:filterLookup];

    [stillImageSource useNextFrameForImageCapture];
    [lookupImageSource useNextFrameForImageCapture];

    [stillImageSource processImage];
    [lookupImageSource processImage];

    finishedImage = [filterLookup imageFromCurrentFramebuffer];

Answer 1

问题解决了，我在GPUImageLookupFilter上错过了额外的useNextFrameForImageCapture。
