Question

我正在尝试将Brad Larson's GPUImage framework集成到我的项目中。示例代码工作正常。在我整合之后，它构建得很好，但我在运行时遇到了崩溃。它在AVCaptureVideoDataOutputSampleBufferDelegate方法崩溃，

- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection;

特别是 runOnMainQueueWithoutDeadlocking阻止。我试图找出崩溃区域但是在看到崩溃日志几个小时之后也找不到它。我对崩溃没有任何了解。下面是我的崩溃日志。有人可以指出我的问题吗？我还怀疑，我可以使用名称com.sunsetlakesoftware.GPUImage.processingQueue继续队列吗？

Answer 1

最后，我找到了解决方案。我刚刚在目标的编译源中替换了AppDelegate的编译器标志，这是为了ARC的目的而设置的。即我删除了-fno-objc-arc标志，并将其替换为导致崩溃的AppDelegate类的-fobjc-arc标志。

整合Brad Larson的GPUImage时崩溃
