  • Unable to connect to UDP through opencv [closed]

    16 février 2020, par Heyyaya

    Currently on my windows laptop, I have setup a project which uses OpenCV to get live feed (udp) off my drone using the cv2.VideoCapture("udp ://@") command. It works very well, yet when I try running my code on the pi, it doesn’t recognize the video capture and returns errors including, unable to resize null object. Is there something I need installed inorder to get this working ?

    Thanks

  • Opencv cv2.VideoCapture('file.avi') shows first frame then throws exception

    3 novembre 2014, par holografix

    I’m trying to read a .avi included in the OpenCV original package, it’s called 768x576.avi and shows a few people walking around a street.

    The code below shows what seems to be the 1st frame and runs for a few seconds before returning an Exception.

    import cv2
    
cap = cv2.VideoCapture('768x576.avi')
    
cap.isOpened() # returns True
    
cap.get(3); cap.get(4) # returns 768 and 576
    

    
while (True):
    
    ret, frame = cap.read()
    
    cv2.imshow('frame', frame)

    Hands me this error after a few secs on the cv2.imshow line, I think it means the returned frame had no data associated it in.

    error: /tmp/opencv-7y6HHt/opencv-2.4.9/modules/highgui/src/window.cpp:261: error: (-215) size.width>0 && size.height>0 in function imshow

    I have no idea why this is happening, I’m running Yosemite, brew installed Python, OpenCv and Ffmpeg.

  • failed to set frame number in opencv in cpp

    28 février 2018, par Madhu Nadendla

    I am trying to set frame position of opened videofile using OpenCV in C++ but it returns 0.

    solution 1

    bool success = capture.set(CV_CAP_PROP_POS_FRAMES, noFrame);
    

    
double frameRate = capture.get(CV_CAP_PROP_FPS);
