cuGraphicsEGLRegisterImage can't register RGB

Accelerated Computing CUDA CUDA Programming and Performance

Hello,

I was trying to read a Jpg Image with the “NvJpegDecoder”, than comvert it to RGB with the “NvBufferTransform” method.
When I then try to get a CuResource from this Buffer, via the “NvEGLImageFromFd” and “cuGraphicsEGLRegisterImage” Methods I get a “CUDA_ERROR_INVALID_VALUE” Error.
This don’t happens when the Image isn’t converted to RGB (so it is sill YUV420_SEMIPLANAR).

Is there any possibility to map register an RGB image or access the NvBuffer directly from CUDA?

I’m using CUDA 10.2

Ok it seems as if this was some weird bug. I first used a work around and than I had to write to an empty ARGB Buffer, which work fine. After that I tried to read from the decoded and transformed buffer again and this time it worked as expected.
