OpenCV VideoWriter Error when using DIVX codec (vs2008, Win7, x64)

Question

Hello,

I'm trying to save a video to a file using OpenCV. But when I want to use more advanced codecs like DIVX or something I get the following error as soon as i call operator <<. For example the following snippet will bring up the error:

cv::VideoWriter testwriter("C:\\test.avi", CV_FOURCC('D', 'I', 'V',  'X'), 25, cv::Size(500,500));
cv::Mat img(500,500,CV_8UC3);

if (testwriter.isOpened()){
        testwriter << img;
}

The error message is:

Unhandled exception at 0x659c1f45 (opencv_ffmpeg210d.dll) in main.exe: 0xC0000005: Access violation reading location 0x00000000.

Other Codecs like MPG-1 (CV_FOURCC('P', 'I', 'M', '1')) also produce the error. It seems it works only with RAW RGB or IYUV.

Any ideas?

Thanks!!
