  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • PHP FFMPEG not working when I upload mp4 file

    9 août 2013, par Chris

    To convert video to formats compatible with HTML5 video I wrote the following script :

        $srcFile = "name/of/the/video.mp4";
    
    $destFile = "/media/video/newfilename";
    
    $ffmpegPath = "/usr/local/bin/ffmpeg";
    
    $flvtool2Path = "/usr/local/bin/flvtool2";
    

    
    // Create our FFMPEG-PHP class
    
    $ffmpegObj = new ffmpeg_movie($srcFile);
    
    // Save our needed variables
    
    $srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
    
    $srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
    
    $srcFPS = $ffmpegObj->getFrameRate();
    
    $srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
    
    $srcAR = $ffmpegObj->getAudioSampleRate();
    
    $srcVB = floor($ffmpegObj->getVideoBitRate()/1000); 
    

    

    
    // Call our convert using exec() to convert to the three file types needed by HTML5
    
    exec($ffmpegPath . " -i ". $srcFile ." -vcodec libx264 -vpre hq -vpre ipod640 -b ".$srcVB."k -bt 100k -acodec libfaac -ab " . $srcAB . "k -ac 2 -s " . $srcWidth . "x" . $srcHeight . " ".$destFile.".mp4");
    

    
    exec($ffmpegPath . " -i ". $srcFile ." -vcodec libvpx -r ".$srcFPS." -b ".$srcVB."k -acodec libvorbis -ab " . $srcAB . " -ac 2 -f webm -g 30 -s " . $srcWidth . "x" . $srcHeight . " ".$destFile.".webm");
    

    
    exec($ffmpegPath . " -i ". $srcFile ." -vcodec libtheora -r ".$srcFPS." -b ".$srcVB."k -acodec libvorbis -ab " . $srcAB . "k -ac 2 -s " . $srcWidth . "x" . $srcHeight . " ".$destFile.".ogv");

    It is supposed to take any input video type and convert it to mp4, ogv and webm. When I run the script on a .mov file it returns a mp4 and ogv file, but not webm. When I run it on a .mp4 file it returns no converted files at all. Is there something wrong with the way I am converting the files ? Any help ?

  • ffmpeg : create interlaced output from progrssive input

    6 février 2012, par user1190908

    I have a 720p60 (54.94 to be exact) clip that I would like to scale down and output in 540i30 (27.97 to be exact).

    Here is my command line :

    ffmpeg.exe -i clip720p60.m2t -ss 90 -t 30 -vcodec libxvid -s 960x540 -b 1000k -r 29.97 -acodec libmp3lame -ar 22050 -ab 64k -f avi clip540i30.avi

    Stream #0.1: Audio: libmp3lame, 22050 Hz, stereo, s16, 64 kb/s
    
...

    The first options indicates to encode 30s at 90s past the start.

    Whatever options I tried up to now always end up with a video stream of 60s and an audio stream of 30s in the output clip.

    Can any one help me ?
