How to install ffmpeg on a Windows Dockerhub image ?
18 janvier, par Youssef KharoufiI have a program that executes a ffmpeg command to a video input, copies this video and pastes is in an output directory.


Here is my code in case you would want to duplicate it :

OpenCV in Python on Windows does not report correct video properties from VideoReader
24 décembre 2015, par Mircea DavidescuI am running into a problem with using VideoReader in OpenCV with Python. Many of the properties that I should be able to get from the video reader are either somehow invalid (returning 0), or return the wrong number. For instance.
vidFile = cv2.VideoCapture('movie.avi')
vidFile.get(cv2.CAP_PROP_FRAME_COUNT)
vidFile.get(cv2.CAP_PROP_FPS)The first get command returns a wrong value, while the second get command returns 0. The output of the

Because I am using the VideoReader feature I also added C :\opencv\sources\3rdparty\ffmpeg to the system PATH and renamed both opencv_ffmpeg300.dll and opencv_ffmpeg_x64.dll to opencv_ffmpeg300.dll and opencv_ffmpeg300_64.dll respectively, as specified here.
Thank you for your help with this problem !
