Trying to run gpu-example-video_reader example on and AWS GPU instance Quad GPU running Ubuntu server 14.04, OpenCV 3.0, CUDA 7.0. I get the following message
ubuntu@ip-10-51-184-206:~/cv/build/bin$ ./gpu-example-video_reader def.mp4
libdc1394 error: Failed to initialize libdc1394
init done
opengl support available
OpenCV Error: Gpu API call (invalid device ordinal) in allocate, file /home/ubuntu/cv/modules/core/src/cuda/gpu_mat.cu, line 76
terminate called after throwing an instance of 'cv::Exception'
what(): /home/ubuntu/cv/modules/core/src/cuda/gpu_mat.cu:76: error: (-217) invalid device ordinal in function allocate
The example works fine on my local machine. Any suggestions ?
