The problem was after I compiled opencv with the flags I wanted, I forgot to run sudo make install to effectively install all the bindings etc.

By default python finds the cv2 module, but not everything is configured.

I tested the OpenCV waitKey() function on Mac (version 10.12.2) but it didn't seem to work correctly. It always return 255 when no keys pressed as well as any key pressed! I'm wondering whether it's incorrectly installed or it's a bug in OpenCV itself. Any idea to fix it would be appreciated.

Can't access webcam OpenCV 3.3 Python 3

Followed this guide: https://www.scivision.co/anaconda-python-opencv3/

Removed all failed attempts with pip before installing.

Make sure that the commands you execute in the guide above use the version of python you are targeting. Either alias python to python36 or replace it in the commands.

QUESTION

can't read mp4 in opencv3.2 (ubuntu, python3)

Asked 2017-Mar-28 at 07:04

I've ran into a problem with my opencv installation, it is unable to open an mp4 video. My system is ubuntu 16.04, 64bit, opencv3.2 used from python 3.5.

VideoCapture.read returns False and None.

There are other questions with this problem, but they target different platforms or different opencv versions.

Apparently, I'm missing the proper codec. So I ran make uninstall from my build directory, purged opencv* with apt and built from source again. This time making sure that ffmpeg was installed before the compilation.

Here are my steps:

clone opencv and opencv_contrib
cd opencv/
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules -D BUILD_EXAMPLES=ON ..
make -j 8
sudo make install

I checked the output of cmake, ffmpeg is there:

ANSWER

Answered 2017-Mar-19 at 20:26

mp4 videos usually contain videos encoded with h264. This is one of the codecs that are patented and some may require a license, which is why they cannot be shipped by default in ubuntu. You need to install libavcodec-extra in order to enable support for h264 in ffmpeg.

Opencv source compile with cuda generates multiple definition link error

Asked 2017-Mar-06 at 20:21

I want to build the opencv 3.2 with cuda 8 and I have installed all the required libraries for cuda in my linux system which is a Debian 9 testing (stretch) 4.9.0-1-amd64 after generating makefiles with cmake successfully I get multiple definition linkage error by executing make command. I have tried many configurations with cmake and also I have checked almost all the relating issues in many forums but I couldn't find any solution. In cmake, I have changed cuda compiler to gcc-5 since cuda 8 needs gcc compiler no later than version 5 and the default gcc compiler is version 6.3 Here is my cmake configuration output:

ANSWER

Answered 2017-Mar-05 at 06:44

Okay, found a workaround at last. (Btw, I'm using CMake GUI).

You have to uncheck CUDA_SEPARABLE_COMPILATION in the CMake-GUI options.

Unfortunately, this just a workaround and CUDA separable compilation cannot be used in Linux. (You have to use Windows for this). I found this in a issue(https://github.com/opencv/opencv/issues/5557) in the OpenCV repository.

PS:

I am having trouble building OpenCV with Qt5. If you are successful in doing so, please notify me in the comments. Thanks!
