Question

我从我的应用程序中集成的关键工具获取了SIGSEGV / SEGV_ACCERR崩溃报告，这是因为在从睡眠模式恢复后应用程序崩溃后拍摄视频并将应用程序置于睡眠模式15-20分钟在我的情况下这是阻碍问题。请提前解决，建议解决方案以下显示了使用的示例代码：

GPUImageiOSBlurFilter   * blurFilterObj = [[GPUImageiOSBlurFilter alloc] init];
    blurFilterObj.blurRadiusInPixels = 4.5f ;
    blurFilterObj.downsampling = 2.5f ;
    blurFilterObj.saturation = 1.0f;



GPUImageVideoCamera  *liveVideo = [[GPUImageVideoCamera alloc] initWithSessionPreset:AVCaptureSessionPresetMedium cameraPosition:AVCaptureDevicePositionFront];
    liveVideo.outputImageOrientation = UIInterfaceOrientationPortrait;
    liveVideo.horizontallyMirrorFrontFacingCamera = YES ;

    //Add Targets to live video
    [liveVideo addTarget:blurView];
   [liveVideo addTarget:blurFilterObj];
 [blurFilterObj addTarget:blurView];

   CSBlurView  *blurView = [[CSBlurView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    [self.view addSubview:blurView];

GPUImageVideoCamera  *liveVideo = [[GPUImageVideoCamera alloc] initWithSessionPreset:AVCaptureSessionPresetMedium cameraPosition:AVCaptureDevicePositionFront];
    liveVideo.outputImageOrientation = UIInterfaceOrientationPortrait;
    liveVideo.horizontallyMirrorFrontFacingCamera = YES ;

    //Add Targets to live video
    [liveVideo addTarget:blurView];
   [liveVideo addTarget:blurFilterObj];
 [blurFilterObj addTarget:blurView];

以下代表崩溃报告

我从开发GPUImage过滤器api的BradLarson那里得到了解决方案，他从github资源回复。当我们使用gpuimagevideocamera时，它总是呈现opengl，所以当它进入后台模式或睡眠模式时也会渲染opengl然后崩溃将发生，所以，在app移动到后台停止相机捕获并删除添加到相机和图片编写器的过滤器它解决了这个问题。谢谢
