where to put opencv2 ffmpeg.dll in path in conda environment ?
28 juillet 2020, par smaillisIm trying to load a saved mp4 video with opencv with th following code found somewhere on SO, and cap.isOpened() returns false. I looked around and some says its to do with the ffmpeg.dll not on PATH, but I found it in my conda env directory
env\Lib\site-packages\cv2\opencv_videoio_ffmpeg430_64.dll


How do I fix this ?


Also VideoCapture(0) works fine (camera stream works).


import cv2
import numpy as np

cap = cv2.VideoCapture('../sandbox/vid.mp4') 
if (cap.isOpened()== False):
 print("Error opening video stream or file")

while(cap.isOpened()):
 ret, frame = cap.read()
 if ret == True:
 cv2.imshow('Frame',frame)
 if cv2.waitKey(25) & 0xFF == ord('q'):
 break 

cap.release()
cv2.destroyAllWindows()



Platform Windows 10


>>>cv.__version__
'4.3.0'

Cannot get file path when user pick from intent - Android content uri [duplicate]
29 juin 2021, par tom55Base scenario :
I want to allow user to pick a file (video) and trim it and save to other location (source / destination locations are local only).


Way I am trying this :
I use
Intent
allowing user to pick a video file. Then I useFFmpeg
on Android, some wrapper library to be precise.

Problem :

FFmpeg
needs an absolute path to file, whereasOPEN_DOCUMENT
orACTION_PICK
kind of intents provide withUri
(content
scheme to be precise)

How to get an absolute path to file having such an Uri ? I have read there is a lot of hassle with it. Or how can I get
file
schemedUri
from a picker Intent ? In overall : how to achieve my base scenario without having to write my own file browser, maybe not use FFmpeg ?
