I just came into the world of openCV and python, and I'm having a strange issue with opening the video stream. This is the code that I'm using:
import numpy
import cv2
cap = cv2.VideoCapture('SampleVideo.mp4')
print(cap.isOpened())
while(cap.isOpened()):
ret, frame = cap.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
This code can successfully open the video stream when i run it in terminal(windows command line) but not in Pycharm. This is the result of the run in Pycharm:
False
Process finished with exit code 0
Any help would be appreciated. Thank you all!
Codec: FFmpeg. OS: Windows 8.1. Python: 3.5.2. OpenCV: 3.1
Update Sep.27:
I noticed that the code runs successfully in IDLE, but not in PyCharm. Now I'm really confused.
I can also confirm that imread and imwrite works properly in PyCharm. So maybe it is the Codec that is not working? How to check my codec in OpenCV?
Update Sep.29:
Now I think I've ruled out the possibility that the terminal and PyCharm are using different interpreter. I really think it's somehow that the default codec is not linked in the PyCharm environment. How do I check my default system codec either in OpenCV or Python?
The problem is solved.
I solved it by purging everything, Pycharm, Python and all the packages. So obviously this issue came from some sort of dependency mess-up. Not really sure what it is, but purging is the way to go people.
