Description
System Information
OpenCV version: 4.x
Operating System / Platform: openSUSE Tumbleweed (20221102) / Linux
Compiler & compiler version: g++ (SUSE Linux) 12.2.1 20221020 [revision 0aaef83351473e8f4eb774f8f999bbe87a4866d7]
Detailed description
When a CL/GL interop function like convertToGLTexture2D fails it doesn't report the cl status. e.g.:
opencv/modules/core/src/opengl.cpp
Lines 1761 to 1762 in 6ca205a
| if (status != CL_SUCCESS) | |
| CV_Error(cv::Error::OpenCLApiCallError, "OpenCL: clCreateFromGLTexture failed"); |
I would like to change that to (for every instance):
if (status != CL_SUCCESS)
CV_Error(cv::Error::OpenCLApiCallError, "OpenCL: clCreateFromGLTexture failed: " + std::to_string(status));Steps to reproduce
cv::ogl::Texture2D tex(cv::Size(WIDTH, HEIGHT), cv::ogl::Texture2D::RGBA, false);
GLuint texId = tex.texId();
glDeleteTextures(1, &texId);
cv::UMat um;
convertFromGLTexture2D(tex, um);results in:
OpenCV(4.6.0-dev) Error: Unknown error code -220 (OpenCL: clCreateFromGLTexture failed) in convertFromGLTexture2D, file /home/elchaschab/devel/opencv/modules/core/src/opengl.cpp, line 1843
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(4.6.0-dev) /home/elchaschab/devel/opencv/modules/core/src/opengl.cpp:1843: error: (-220:Unknown error code -220) OpenCL: clCreateFromGLTexture failed in function 'convertFromGLTexture2D'
No CL status.
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
