TOTAL_FRAMES_FLAG = cv2.CAP_PROP_FRAME_COUNTĪnd this is what happens in my ubuntu environment: Here is my procedure for compiling and installing FFmpeg from source on Ubuntu 18.04. 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.

Pip install ffmpeg ubuntu
