  • Opening file with unknown extension (Mjpeg ?) in OpenCV python

    14 novembre 2013, par bw4sz

    I am trying to open a third party video file into OpenCV with python.
    My camera (plotwatcher camera trap) shoots in a silly proprietary format. The extension is unique (.tlv) but i can play the file in VLC, and using ffmpeg i can see the following encoding :

    C:\Users\Ben>ffmpeg -i C:/Users/Ben/Documents/OpenCV_HummingbirdsMotion/PlotwatcherTest.tlv

    From this i can see file is encoded into mjpeg format.

    How can i open this file in open cv ?

    import cv2
    
#import cv2.cv as cv
    
import numpy as np
    
cap = cv2.VideoCapture("C:/Users/Ben/Documents/OpenCV_HummingbirdsMotion/PlotwatcherTest.mjpg")
    
ret, frame = cap.read()
    
#show first image
    
cv2.imshow('my window',frame)
    
cv2.waitKey(0)
    
cv2.destroyWindow('my window')

    I can see nothing has been loaded. When i try to view the first frame i get the error :

    File "C:\Users\Ben\Documents\OpenCV_HummingbirdsMotion\Test.py", line 21, in <module>
    
cv2.imshow(&#39;my window&#39;,frame)
    
error: ..\..\..\..\opencv\modules\highgui\src\window.cpp:261: error: (-215)
    
size.width>0        &amp;&amp; size.height>0
    
</module>

    I've tried leaving the native .tlv, mjpeg and mjpg, and .MJPG endings following the conceptual idea found here : MJPEG stream fails to open in OpenCV 2.4

    i appreciate all help !

  • PHP extension writing

    19 octobre 2013, par Mikko Koppanen — Imagick

    I’ve written quite a few PHP extensions over the past years and thought that I could share some of the experience with larger community. PHP internals can be a bit scary at times and in the past I’ve scoured through a lot of extensions to find practical examples of things such as how to return objects from internal functions/methods, how to handle different types of parameters, class properties etc.

    To document some of the experiences I started a project called extsample, in which I plan to add practical examples related to extension writing. There won’t be extensive written documentation outside the code, but hopefully the code itself contains enough nuggets of information to be useful. As the README says, if you need a specific example or clarification on something just open an issue in Github.

    The project is still very fresh but hopefully soon it will contain more examples. Pull requests are also welcome if you have code that you want to share with others.
