gpu decoder- all CUDA-capable devices are busy or unavailable in function 'allocate'

edit

I'm trying to run an OpenCV sample code presented here: https://github.com/opencv/opencv/blob..., but it gives following error at cv::cudacodec::createVideoReader(fname).

Error:

terminate called after throwing an instance of 'cv::Exception'
  what():  OpenC`enter code here`V(4.0.1) /opt/GPU_READ/opencv-4.0.1/modules/core/src/cuda/gpu_mat.cu:121: error: (-217:Gpu API call) all CUDA-capable devices are busy or unavailable in function 'allocate'

Aborted (core dumped)
