Hi,
For some reason, i need to convert an OpenCV image to Evas Image, i do:
opencv_image = imread("fruits.jpg", 1);
cvtColor(opencv_image, opencv_image, CV_BGR2BGRA);
evas_image = evas_object_image_add(canvas);
evas_object_image_colorspace_set(evas_image, EVAS_COLORSPACE_ARGB8888);
evas_object_image_size_set(evas_image, opencv_image.size().width,
opencv_image.size().height);
evas_object_image_fill_set(evas_image, 0, 0, opencv_image.size().width,
opencv_image.size().height);
evas_object_resize (evas_image, opencv_image.size().width,
opencv_image.size().height);
evas_object_image_data_set(evas_image, opencv_image.data);
evas_object_show(evas_image);
This code is perfectly working, for only one image, so i created an
Ecore Timer to get image in real time from my webcam:
timer = ecore_timer_add(0.01, update, NULL);
My update function is:
Mat opencv_image;
opencv_image = cvQueryFrame(capture);
cvtColor(opencv_image, opencv_image, CV_BGR2BGRA);
evas_object_image_size_set(evas_image, opencv_image.size().width,
opencv_image.size().height);
evas_object_image_fill_set(evas_image, 0, 0, opencv_image.size().width,
opencv_image.size().height);
evas_object_resize (evas_image, opencv_image.size().width,
opencv_image.size().height);
evas_object_image_data_set(evas_image, opencv_image.data);
but when i'm running this, i get:
Program received signal SIGSEGV, Segmentation fault.

Someone know if it's a bug in evas or if i do something wrong ?
I'm using efl from git.
Thanks in advance for your response.
Nicolas.
