So I've installed OpenCV on Arch Linux.
- I've now tried building from source and alternatively using the Arch repo (via
pacman -Syu base-devel opencv opencv-samples). In both cases I can (eventually) get the Display Image tutorial to work. - Also confirmed the system can find the libraries via
pkg-config --libs opencv
Now progressing to my main purpose, video, I hit problems:
- Testing the VideoIO tutorials
- Compiling requires code similar to "g++ -o test_1 test_1.cpp
pkg-config opencv --cflags --libs" - Running this output (via
./opencv_video Megamind.avi Megamind_bugy.avi 35 10) hits several errors..
Unable to stop the stream: Inappropriate ioctl for device
(ERROR)icvOpenAVI_XINE(): Unable to open source 'Megamind.avi'
Unable to stop the stream: Inappropriate ioctl for device
(ERROR)icvOpenAVI_XINE(): Unable to open source 'Megamind_bugy.avi'
Could not open reference Megamind.avi
This occurs no matter which original install method I use (both building from source and from the Arch Linux repo). The errors don't particularly help, as after a couple of hours and down several rabbit trails I don't seem to be any further.
Hoping someone might be able to direct me towards a solution. Thanks for reading!
