OpenCV 3.0的问题-记录视频内存泄漏

Question

抱歉，问一个老问题，但我什么也帮不上忙。我正在使用iOS 3.0框架开发一个OpenCV应用程序。

我使用cvVideoCamera延迟记录视频，但是当我设置_cvVideoCam.recordVideo = YES;时，它总是给我内存警告错误。如果我设置了cvVideoCam,recordVideo = YES;，那么就没有任何内存警告，但是在记录完成时，输出url总是在位置显示(null)。

提前谢谢。

    please check your

    -(void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer.....

     for - 
                                                     withPresentationTime:lastSampleTime] ) 
    {
                         NSLog(@"Video Writing Error");
                     }
                    if (pixelBuffer != nullptr)
                        CVPixelBufferRelease(pixelBuffer);
                 }

             }

because, in some of earlier version OpenCV forgot to release memory upon each append operation to MPEG4 output. May be its your need.
