  • 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" (...)

  • ffmpeg causes browser to hang up ?

    24 juillet 2012, par Itai Sagi

    I'm using ffmpeg to convert videos on the fly, as they say, and I'm facing with a very annoying, unsolvable and unreferenced problem (as of yet ;) ), when I run my php script, it basically works - takes the file, uses ffmpeg, starts converting it, but halway through it's finished, the browser hangs, I don't understand why or how to resolve it :
    (even with set_time_limit the bastard won't work).

    function convertToMp4(){
    
    /*
    
     * Converts a file to mp4, returns the new file name
    
     */
    
    set_time_limit(0);
    
    $tmpFile = $this->fileName;
    
    $newFile = uniqid();
    
    $outputFile = "output/$justFile.mp4";
    
    exec("ffmpeg -i " . $tmpFile . " -acodec copy -ar 44100 -ab 96k " . $outputFile. " &");
    
    unlink($tmpFile);
    
    return $outputFile;
    
}

  • FFMPEG for Windows - suggestions for how to overcome the " No such file or directory" issue

    11 mars 2023, par Scott Hatton

    I am using FFMPEG (Windows version)

    


    I have files called 'MCR_0400.jpeg' numbered sequentially up to 'MCR_0450.jpeg'

    


    When I run :
ffmpeg -i 'MCR_%4d.jpeg' -start_number 0400 -c:v libx264 out.mp4

    


    it returns :
Could find no file with path 'MCR_%4d.jpeg' and index in the range 0-4
'MCR_%4d.jpeg' : No such file or directory

    


    I have spend the day trying all sorts of variations on the file name parameter : with and without quotes, full Windows path to it so I assume I'm doing something really stupidly wrong.

    


    But I just cannot fathom it.

    


    Can anybody help ?

    


  • OpenCV in Python on Windows does not report correct video properties from VideoReader

    24 décembre 2015, par Mircea Davidescu

    I am running into a problem with using VideoReader in OpenCV with Python. Many of the properties that I should be able to get from the video reader are either somehow invalid (returning 0), or return the wrong number. For instance.

    vidFile = cv2.VideoCapture('movie.avi')
    
vidFile.get(cv2.CAP_PROP_FRAME_COUNT)
    
vidFile.get(cv2.CAP_PROP_FPS)

    The first get command returns a wrong value, while the second get command returns 0. The output of the ffprobe command is given below :

30 tbc

    I am running a Windows 10 machine with Python 2.7.11 (Anaconda 2.4.1 64-bit). I have installed OpenCV 3.0.0 according the instructions provided here. Because I am using the VideoReader feature I also added C :\opencv\sources\3rdparty\ffmpeg to the system PATH and renamed both opencv_ffmpeg300.dll and opencv_ffmpeg_x64.dll to opencv_ffmpeg300.dll and opencv_ffmpeg300_64.dll respectively, as specified here.

    Thank you for your help with this problem !
