  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • cap.isOpened() : returns false in CentOS for Python 3 and OpenCV 3.1.0

    29 octobre 2017, par Mona Jalal

    So cap from opencv 3 doesn’t work in CentOS. I had no problem in OSX or Windows 7 which I tried initially.
    Here is the example code :

    import cv2
    
cap = cv2.VideoCapture('/home/grad3/jalal/PycharmProjects/hw4_cs58‌​5/Concession_LAN_8‌​‌​00‌​k.mp4',cv2.CAP_FFMPEG)
    

    
if not cap.isOpened():
    
    print('not opened')
    

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

    
    if ret == False:
    
        print('frame empty')
    
        break
    
    cv2.imshow('frame', frame)
    
    if cv2.waitKey(1) == ord('q'):
    
        break

    And I get :

    /usr/local/anaconda3/bin/python /home/grad3/jalal/PycharmProjects/hw4_cs585/test.py
    
not opened
    
frame empty
    

    
Process finished with exit code 0

    I can open the video using ffplay vid_name and also here is the result of https://pastebin.com/YGk2DDCi here https://pastebin.com/HSyHSsEZ (ffmpeg codecs). How should I fix this ?

    I have opencv 3.1.0 and here’s some sys info.

  • ffmpeg configure always returns "not found" when using sysroot and cross-prefix options - how to use them correctly ?

    5 août 2014, par user2212461

    I try to build ffmpeg with a cross-compiler. When setting the configure flags I am getting the following errors :

    WARNING: Compiler does not indicate floating-point ABI, guessing soft.
    
build_it.sh: 29: build_it.sh: --sysroot=/home/android/android-ndk-r9/platforms/

    The error message "not found" sounds like the paths dont exist but they are all correct and existing. How can I resolve this error ?
