  • Debian ffmpeg working in terminal but not in php

    30 octobre 2013, par user2938660

    I reinstalled ffmpeg on debian and php exec doesn't work for me anymore when called from php. I'm using :

    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";
    
        //$conv_name2 = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
        $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
        //$fastarted_file  = _VIDEOS_DIR_PATH.$conv_name2;
    
        $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -r 20 -g 40 -acodec libfaac -ar 44100 -ab 96k -vcodec libx264 -sameq '.$converted_file;
    
        //$faststart_command = "qt-faststart ".$converted_file." ".$fastarted_file;
    
        shell_exec($ffmpeg_command);
    
        unlink($convert_source);
    
        //shell_exec($faststart_command);
    
        $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
    
        $result = @mysql_query($sql);
    
}
    
echo $success_msg;

    this code to convert videos and ffmpeg output is :

    9 avril 2020, par Westicle

    When I use ffmpeg I use it like this :

    



    ./ffmpeg -ss 00:30:00 -i inputvideo.mp4 -t 00:00:20 -c:v copy -c:a copy outputvideo.mp4


    



    So how to I use ffprobe ? I've tried this but I can't get it to work :

    



    ./ffmpeg ffprobe -v error -show_frames inputvideo.mp4


    


  • Real time ffmpeg output from terminal in php

    8 novembre 2014, par user2978381

    I am using this code to get real time update from windows terminal. It doesn’t output anything in the browser but process the command and in the background and completes the conversion.

        set_time_limit(0);
    
    $ffmpegCommand  = 'C:\\ffmpeg\\bin\\ffmpeg';
    

    
    $handle = popen($ffmpegCommand." -i upload/1415292048.mp4 -ar 22050 -ab 32 -f flv -s 640x320 -vcodec libx264  -vsync 1  -bt 50k converted/video001.flv", "r");
    

    
    if (ob_get_level() == 0) 
    
        ob_start();
    

    
    while(!feof($handle)) {
    

    
        $buffer = fread($handle, 4096);
    
        $buffer = trim(htmlspecialchars($buffer));
    
        echo "<pre>";
    

    
        echo $buffer ;
    
        echo str_pad('', 4096);
    
        echo "</pre>";
    

    
        ob_flush();
    
        flush();
    
        sleep(1);
    
    }
    

    
    pclose($handle);
    
    ob_end_flush();

    But when the same code I am using for youtube_dl it updates in the real time.

        header('Content-Encoding: none;');
    

    
    set_time_limit(0);
    

    
    $handle = popen("python -m youtube_dl -F http://vimeo.com/30261818", "r");
    

    
    if (ob_get_level() == 0) 
    
        ob_start();
    

    
    while(!feof($handle)) {
    

    
        $buffer = fread($handle, 4096);
    
        $buffer = trim(htmlspecialchars($buffer));
    
        echo "<pre>";
    

    
        echo $buffer ;
    
        echo str_pad('', 4096);
    
        echo "</pre>";
    

    
        ob_flush();
    
        flush();
    
        sleep(1);
    
    }
    

    
    pclose($handle);
    
    ob_end_flush();

    So if I want to show output of ffmpeg in the browser what should I do ?
