Hi!
I've decided to start using the OpenCV 3.2 CUDA interface and I want to use the cv::cudacodec::createVideoWriter() function and writer->write(gpu_frame) to write directly from the GPU memory. I've successfully built OpenCV 3.2 with CUDA 8.0 and the flags WITH_CUBLAS, WITH_CUDA and WITH_NCUVID. I have also successfully read directly into the GPU memory using the cv::cudacodec::createVideoReader() function and reader->nextFrame(gpu_frame).
My problem arises when I try to create a writer to the GPU memory using cv::cudacodec::createVideoWriter(). I then get an unhandled exception and an OpenCV Error saying:
OpenCV Error: The function/feature is not implemented (The called functionality is disabled for current build or platform) in throw_no_cuda, file C;\opencv\source\modules\core\include\opencv2/core/private.cuda.hpp, line 101
To me this sounds as if I am missing a package in my build of OpenCV, but I thought that cv::cudacodec:createVideoWriter() was included in NCUVID. This seems pretty strange to me, but maybe some of you guys know more about this? Any help at all is appreciated!
PS: I have also overwritten the version of CUDA 8.0 to include cuDNN. I dont know if this makes any difference, but I thought I'd mention it.
it. EDIT: Added the OpenCV 3.2 buildlog output.
