    Default Read video with Qt and Opencv

    Hello!

    I need load a video files with opencv.
    I used this programming in the main.cpp.

    VideoCapture capture("video2_alcorcon.avi");
    for(; {

    capture >> src;
    imshow("imagen", src);
    waitKey(10);
    }

    In file.pro I include:


    INCLUDEPATH += C:\\Users\\Amaia\\Desktop\\opencvmin\\install\\inc lude
    LIBS += -LC:\\Users\\Amaia\\Desktop\\opencvmin\\install\\li b \
    -lopencv_core240 \
    -lopencv_highgui240 \
    -lopencv_imgproc240 \
    -lopencv_features2d240 \
    -lopencv_calib3d240

    And in header too:


    #include <opencv/cv.h>
    #include <opencv2/core/core.hpp>
    #include <opencv2/highgui/highgui.hpp>
    #include <opencv2/imgproc/imgproc.hpp>

    using namespace cv; //opencv

    But, I have got an error (file upload). I'm looking for a solution but I haven´t got.

    Please help me. I need use opencv in my proyect.

    why don't you ask on an opencv forum?
    If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

    The problem is you are in a Qt forum asking a question that has nothing but the most tenuous link to Qt.

    If it compiles (it seems to) then the problem is at run time. The most likely issue is that the OpenCV libraries are not in the PATH and thus are not found.

    Here is the OpenCV forum to start in: http://answers.opencv.org/questions/
