I'm trying to run an OpenCV sample code presented here: https://github.com/opencv/opencv/blob/master/samples/gpu/video_reader.cpp, 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)
Nvidia version : NVIDIA-SMI 390.96
This is a configuration of OpenCV:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D WITH_FFMPEG=ON -D WITH_CUDA=ON -D WITH_NVCUVID=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=ON -D BUILD_JAVA=OFF -D BUILD_SHARED_LIBS=ON -D BUILD_DOCS=OFF -D OPENCV_EXTRA_MODULES_PATH=/tmp/opencv_contrib-4.0.1/modules -D BUILD_EXAMPLES=ON -D WITH_VFW=ON -DWITH_GSTREAMER=ON -D WITH_OPENGL=ON -DWITH_MSMF=ON -D WITH_QT=ON ..
