Pencv python ffmpeg how to#

I had written a detailed post earlier on how to find OpenCV version.īut if you want the full build information, you need to use getBuildInformation. It can be mind numbing to figure out what option you had used while compiling or installing OpenCV. Use a numpy you've installed yourself instead of a Homebrew-packaged numpyīuild without accuracy & performance tests Use QuickTime for Video I/O instead of QTKitĮnable parallel code in OpenCV using Intel TBB Last edited by jlb222 June 23rd, 2017 at 04:45 PM.Build with libjpeg-turbo instead of libjpegīuild with OpenGL support (must use -with-qt)

for example cv2.imshow() will not work (not compiled with GTK+ 2.x or Carbon support).

video related functionality is not supported (not compiled with FFmpeg).

MacOS and Linux wheels have currently some limitations: Successfully uninstalled opencv-python-3.2.0.7Īs you probably know (but I didn’t) opencv-python is a lightweight package with a partial opencv functionality that can be used INSTEAD of the original libraries as stated in the documentation ( ): Successfully installed opencv-python-3.2.0.7

Installing collected packages: opencv-python TOTAL_FRAMES_FLAG = cv2.CAP_PROP_FRAME_COUNTĪnd this is what happens in my ubuntu environment: Here is an example, this is my test.py file:Ĭap = cv2.VideoCapture('/home/envac/Documentos/GOPR0043.MP4') When I uninstalled it from my system, I was finally able to handle video files. However, my problem was that I was pip installing the opencv-python package on top pf the OpenCV installation from source and this blocked acces to the real libraries. FFMPEG did not work because I had deleted the references to opencv_core that are required this was not fixed by uninstalling and reinstalling FFMPEG and was solved after Ubuntu was reinstalled. In the end, I had several problems in my project.

Thanks SeijiSensei and monkeybrain, but my problem was somewhere else.
