  • 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 (...)

  • Les formats acceptés

    28 janvier 2010, par

    Les commandes suivantes permettent d’avoir des informations sur les formats et codecs gérés par l’installation local de ffmpeg :
    ffmpeg -codecs ffmpeg -formats
    Les format videos acceptés en entrée
    Cette liste est non exhaustive, elle met en exergue les principaux formats utilisés : h264 : H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 m4v : raw MPEG-4 video format flv : Flash Video (FLV) / Sorenson Spark / Sorenson H.263 Theora wmv :

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • ffmpeg after converting avi to mp4 need wait till video loads in flash player 100% otherwise video is buffering

    28 octobre 2013, par Xenos Trojanowicz

    So if fixed all issues with my ffmpeg journey now I just need that after converting videos they play in flash player instantly and no need to wait till video loeaded 100% I use :

    if ($success_msg) {
    
    $tmp_parts = explode('.', $file['name']);
    
    $ext = array_pop($tmp_parts);
    
    $ext = strtolower($ext);
    
    if($ext == "avi" && $convert_avi == true) {
    
        $convert_source = _VIDEOS_DIR_PATH.$new_name;
    
        $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
        $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
        $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libfaac -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
    
        echo exec($ffmpeg_command);
    
        $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
    
        $result = @mysql_query($sql);
    
        unlink($convert_source);
    
    }
    
    echo $success_msg;
    
}

    To convert videos

  • python call of ffmpeg misses target file parameter

    2 décembre 2016, par Fred

    I’m writing a python GUI for ffmpeg. When calling ffmpeg via subprocess it runs fine as long as the command is like

    subprocess.Popen([ffmpeg_converter,
    
        '-i',file,
    
        target_file
    
        ])

    But when I do the same call with ffmpeg arguments it fails with
    "At least one output file must be specified" :

    option_string = '-q:a 4'
    
subprocess.Popen([ffmpeg_converter,
    
        '-i',file,
    
        option_string,
    
        target_file
    
        ])

    It even recognizes the options but does not see the target file. I even replaced the actual target file with someting simple like "test.mp3" but still the same error. Any ideas ? (I’m on windows with python 3.3.)

    The complete console output is :
