Hello,

I have a simple question:

I want to process with OpenCL some video encoded in BGR 24 bits that I read with OpenCV. Basically it returns me a pointer to the frame data.

For the moment I use OCL buffers, and I want to use image2D instead.

It should be something like :

cl_image_format rgb_format;           rgb_format.image_channel_order = CL_RGB;           rgb_format.image_channel_data_type = CL_UNSIGNED_INT8;

but when I've checked at the standard the cl_image_format that i need to create is not allow.

Am I wrong? Did I miss something? And if I understood properly How could i solve my problem?

Thanks for your time,

Etienne

you must use CL_RGBA. convert 24 bit image to 32 bit image manualy on CPU or write kernel which take buffer and copy it to image.

Yeah,

just what I feared.

Ok thanks for the reply. I'm gonna try that.

Bye
