Revision history [back]

I'm developing a software that has a few threads writing 10 to 50 bitmap files per second and sometimes I'm getting this exception.Each thread writes its bitmap files into different folders.

I tried cloning the cv::Mat just before imwrite(), or getting a lock before calling imwrite() but those didn't help.

Each threads uses this code to write bitmap files.

cv::Mat source_image;  // UINT8, 1x128x130

// do some processing to the source_image;

cv::Mat cloned_image = source_image.clone();
if ((cloned_image.rows > 0) && (cloned_image.cols  >0)) {
    cv::String file_name = "";  // somewhere
    cv::imwrite(file_name, cloned_image);  // THIS IS WHERE I GET THE EXCEPTION
}

Thank you.

I also checked the mini dump file (*.dmp) and the exception code was 0xC0000409.

Thank you.
