Failed to call clEnqueueCopyImage between src(clCreateFromEGLImageKHR) and dst(clCreateImage)

lsy2025 over 2 years ago

Recently, I tried to use clEnqueueCopyImage for OpenGL/ES interop with OpenCL. However, it just return -59(CL_INVALID_OPERATION) after calling clEnqueueCopyImage

Use glGenTextures to generate input_gl_tex and check( glGetError() )
Use eglCreateImageKHR to generate input_egl_image with input_gl_tex as parameter and check( eglGetError() )
Use clCreateFromEGLImageKHR to generate input_cl_egl_image with input_egl_image as parameter and check
Use clEnqueueAcquireEGLObjectsKHR to acquire for input_cl_egl_image
Use clEnqueuecopImage between src(input_cl_egl_image) and dst(clCreateImage), it just return CL_INVALID_OPERATION

How could i fix it ?

Hello, I'm afraid older drivers do not support imported images as the source of image copy commands. This restriction is being relaxed for several types of memory and we will make sure that your usage...

I have tried to write a simple kernel to access the Imported EGL images, however, it also return CL_INVALID_OPERATION after calling clEnqueueNDRange. So, I suspect that the Imported EGL images is not truly accessible although calling of clCreateFromEGLImageKHR return true

Before any development begins, the software partner must evaluate the needs of the business and determine the technical requirements. This is known as the product roadmap, which outlines the timetable, budget, and technical plan. Workshops are held to determine the software's design, which is then converted into interactive prototypes and wireframes. User research validates the design, and testing ensures the software meets expectations. Once the prototype is ready, the software developers will start writing code. These hours are accounted for when calculating the cost of custom software development https://mlsdev.com/services/custom-software-development
