Hi,
I'm trying to run an OpenCV sample code presented here: opencv-3.3.1/samples/gpu/video_reader.cpp, but always get an segmentation fault signal within cv::cudacodec::createVideoReader(fname).
The stack trace is:
1 cv::cudacodec::detail::CuvidVideoSource::CuvidVideoSource(cv::String const&)
2 cv::cudacodec::createVideoReader(cv::String const&)
3 main
Further debugging told me that memory access violation occurs at this line of code in opencv-3.3.1/modules/cudacodec/src/cuvid_video_cource.cpp:
CUresult cuRes = cuvidCreateVideoSource(&videoSource_, fname.c_str(), ¶ms);
And seems like it calls an invalid address. Disasm also shows memory access violation at callq command.
Cuda video SDK samples shows that there's a robust dynamic linking presents. Do I need some extra dynamic linking while using OpenCV? Or maybe I do something wrong?
Running ./opencv_test_cudacodec also ends up with segfault.
What is being linked when I compile the sample:
g++ -Wl,--trace,--rpath,/usr/local/lib,--rpath,/usr/local/cuda/lib64 -Wl,-rpath,/home/den/Qt/5.7/gcc_64/lib -o opencv_cuda_test main.o -lopencv_core -lopencv_cudacodec -lopencv_videoio -lopencv_highgui -lnvcuvid -L/usr/local/cuda/lib64 -L/home/den/Qt/5.7/gcc_64/lib -lQt5Core -lpthread
Specs:
- Ubuntu 16.04;
- GeForce GTX 960;
- Driver Version: 384.90;
- CUDA 9.0
- opencv-3.3.1 (tried both release version and latest 'master' branch)
- This is a configuration of OpenCV:
