    Sometimes your computer may give you an error message that says opencv cannot open avi. There can be many reasons for this error.

    1)
    Make sure the video file does indeed work in the same folder as the delivery (I assume you’ve tried this so far), otherwise provide an absolute path.

    opencv cannot open avi

    2)
    On Windows, you may need some kind of codec pack to play most of the file (for example, the K-Lite codec pack).

    As Macmade suggested, AVI is just a repository that can contain various audio, video, or even closed captioning codecs. Here are also the FFmpeg versions of Zeranoe to get Windows to work. You can get additional tips about the content of the codec in the file by following these steps:

      ffmpeg -i Guitarplaying.avi

    As you can see, this .mp4 container contains a specific H.264 video, a specific H.264 video codec, and an AAC audio codec.

    I just wrote a simple video playback example using openCV2.3.1, but it looks like I can't open the AVI video on my own ode :(

    opencv cannot open avi

      Capture VideoCapture ("guitarplaying.avi");if (! capture.isOpened ())    std :: cout << "Video cannot be learned! n";    resume -1;Carpet frame;namedWindow ("Frame");double rate capture = .get (CV_CAP_PROP_FPS);delay int is 1000 / speed;bye (true)    if (! capture.read (frame))        Pause;       Imshow ("frame", frame);     if (waitKey (timeout)> = 0)        Pause;capture.release ();

    I found all breakpoints in std :: cout << "cannot play video! n" and stopped every possibility here. Why won't AVI videos open? Thanks !

    How can I play a fantastic AVI file using Python Opencv? The following code works, but not

    Import

      numpy as npCV2 importimport operating systemcap = cv2.VideoCapture ('/ home / ast / datasets / ewap / seq_eth / seq_eth.avi')ret, frame means cap.read ()seal (salvation)print (np.shape (frame)) 
    
      Invalid()                 Find

    I have a simpler solution! I can read .avi files, but absolutely cannot use cv2.imshow (). Instead, I used matplotlib to show the image. https: //github.com/ContinuumIO/anacon ...

      conda install-Celsius anaconda opencv   Import 

      numpy npsame as import cv2import matplotlib.pyplot plt# as the final videocap = cv2.VideoCapture ('/ home / ast / datasets / ewap / seq_eth / seq_eth.avi')ret, the frame implies cap.read ()plt.figures ()plt.imshow (frame) 
    
      Error Traceback Last (most calls are recent) to  ()     something like 20 # plt.figure ()     18 # plt.imshow (frame)---> 22 cv2.imshow ('frame', frame)error: OpenCV (3.4.1) /opt/conda/conda-bld/opencv-suite_1527005194613/work/modules/highgui/src/window Error: cpp: 636: (-2) Function is not implemented at all. Rebuild the Windows library with GTK + 2.x or Carbon support. If you need to work on Ubuntu or Debian, install libgtk2.0-dev, then pkg-config, restart cmake, or customize the script in the Show cvShowImage Results window.
