[Insight-developers] Video and OpenCV issues

[Bill Lorensen]

I pulled down the patch and still get these errors:

    Start 1: OpenCVVideoCaptureTest
1/4 Test #1: OpenCVVideoCaptureTest ...........***Exception: SegFault  1.44
sec
    Start 2: OpenCVImageBridgeTest
2/4 Test #2: OpenCVImageBridgeTest ............   Passed    0.95 sec
    Start 3: OpenCVVideoIOTest
3/4 Test #3: OpenCVVideoIOTest ................***Failed    0.25 sec
    Start 4: OpenCVVideoIOFactoryTest
4/4 Test #4: OpenCVVideoIOFactoryTest .........***Failed    0.26 sec

The code is not checking for failure here. It shopuld throw an exception.
Of course this will not fix the problem.

247    ::InitializeVideoIO()
248    {
249      m_VideoIO = itk::VideoIOFactory::CreateVideoIO(
250                                    itk::VideoIOFactory::ReadFileMode,
251                                    m_FileName.c_str());
252      m_VideoIO->SetFileName(m_FileName.c_str());
253      m_VideoIO->ReadImageInformation();
254
