cmake-time checks for known broken opencv configurations #20

Maybe this is a Qt thing.... to the best of my knowledge we only test On Sun, Oct 2, 2011 at 10:17 AM, Florian Seidel

Yup, I have never tested against a QT based highgui, only the GTK version. |
|
Could you attach your simple imshow like cell, that uses qt? |
|
I get no crash, but an unusable window. Interesting abi warning from libpng. Malefiz: maybe you want to go with the gtk version instead. VIDIOC_QUERYMENU: Invalid argument |
#include <ecto/ecto.hpp>

namespace hello_ecto {
using ecto::tendrils;
struct ImShow {
static void declare_params(tendrils& params)
{
params.declare<std::string>("name","the name","Window");
}
static void declare_io(const tendrils& params, tendrils& in, tendrils& out)
{
in.declare<cv::Mat>("image","An image",cv::Mat());
}
void configure(const tendrils& params, const tendrils& inputs, const tendrils& outputs){
params["name"]>>name;
image_=inputs["image"];
cv::namedWindow(name,CV_WINDOW_AUTOSIZE);
}
int process(const tendrils& in,const tendrils& out)
{
cv::Mat image = *image_;
if(image.empty())
{
return ecto::OK;
}
cv::imshow(name,image);

std::string name;
ecto::spore<cv::Mat> image_;
};
}
ECTO_CELL(hello_ecto,hello_ecto::ImShow,"ImShow","Shows an image");

Recompiled OpenCV with default options which solved the problem. |
This probably should be generalized
vidcap.py produces a segmentation fault.

I am using opencv 2.3.1. compiled without gstreamer and gtk support. Opencv 2.3.1 c++ examples which use highgui work. Also wrote a very simple imshow like cell, but get the same seg fault.
