Hi,
I'm having performance problems reading video files using OpenCV and Python on a Raspberry Pi. I get around 2 fps. That is just reading the frames, doing nothing else. I have absolutely no problem reading from the camera module. The video I'm trying to read is a .h264 file recorded using the camera module.
Here is my test code:
import numpy as np
import cv2
try:
cap = cv2.VideoCapture('/home/pi/test.h264')
except:
print 'Could not open video file'
i=0
while True:
ret, frame = cap.read()
i+=1
print 'frame ', i
I can play the video fine with omxplayer so it's not a limitation of the Raspberry Pi itself.
Using Python 2.7.3 & OpenCV 2.4.11. Feels like something is wrong somewhere?
