Crash of Directshow plugin with OpenCV when using cv::Mat

Rukkanor · July 18, 2014, 8:45am

Hi, guys

I follow the tutorial to build a Directshow plugin with TemplateExtOpenCV, and everything is OK at the beginning. But when I create a cv::Mat instance and allocate memory for it, the application crashes at runtime and shows a dialog like this:

The debug log is

Any solution?

Maybe rebuild the dynamic libraries in VVVV_ROOT\lib\thirdparty\x86\opencv ?

joreg · July 19, 2014, 11:41am

so if you say you get the example to build but it fails as soon as you add your code i’d suggest your code to be the culprit.

you may also want to have a look at vvvv.packs.image which is the more modern way of using opencv code with vvvv.

Rukkanor · July 21, 2014, 3:35am

hi, joreg, thanks for your reply

1 It should not be that my code has problem, because it’s just a single line such as

cv::Mat a(3, 3, CV_8UC1);

2 Mmm, the big problem is that I’m not familiar with C#

joreg · July 21, 2014, 3:04pm

well if the template works i am afraid i won’t be able to help you further
if you’re familiar with c++ it should be a breeze and delight for you to get into c#

Do you use visual studio to build the plugin? if yes, the compiler version can create that problem. Also there can be issues with memory allocation constraints between debug and release builds.

Generally one easy way to avoid that, is to link against opencv static libs instead of the dynamic libs. That way you get a self contained dll which doesn’t needs megs and megs of externals (and avoid this compiler version issue).

Rukkanor · July 22, 2014, 2:35am

joreg, thank you all the same.

hi, vux
I use code::blocks with MinGW GCC compiler just as the tutorial suggests.
I will try your solution later. For now, I use CvMat instead of cv::Mat, and it works.
Thanks for your help.
