    so i ask some one he told me the exec stop php script and never give me

    You can't get the progress directly if you are using exec, because the php script is stopped until ffmpeg closes. (Because exec returns the whole execution output)
    

    
You should use popen, for being able to get the output from the process in real time (without reading any file) for parse and show the progressbar
    

    
Here is a example for get the output: 
    

    
When you get the progress info from ffmpeg, you can use your code for parse it and show your progressbar

    this is my popen script

    &lt;?php 
    

    
$handle = popen ("ffmpeg.exe -i files/fz.mp4 -ab 192k files/vdf.mp3 2>&amp;1 ", 'r');
    
$handles = (string)$handle;
    
$line = "";
    

    
while (false !== ($char = fgetc($handle)))
    
{
    
  if ($char == "\r")
    
  {
    
    // You could now parse the $line for status information.
    
    echo "$line\n";
    
    $line = "";
    
  } else {
    
    $line .= $char;
    
  }
    
  ob_flush();
    
  flush();
    
}
    
pclose ($handle);
    

    

    
    //get duration of source
    
    preg_match("/Duration: (.*?), start:/", $handles, $matches);
    

    
    $rawDuration = $matches[1];
    

    
    //rawDuration is in 00:00:00.00 format. This converts it to seconds.
    
    $ar = array_reverse(explode(":", $rawDuration));
    
    $duration = floatval($ar[0]);
    
    if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
    
    if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
    

    
    //get the time in the file that is already encoded
    
    preg_match_all("/time=(.*?) bitrate/", $handles, $matches);
    

    
    $rawTime = array_pop($matches);
    

    
    //this is needed if there is more than one match
    
    if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
    

    
    //rawTime is in 00:00:00.00 format. This converts it to seconds.
    
    $ar = array_reverse(explode(":", $rawTime));
    
    $time = floatval($ar[0]);

    &#xA;

    Which mean its keep running but in my code it does not wait until complete merging

    &#xA;

    how can i fix that ??!

    &#xA;

    but i think my problem is in command(concat)

    &#xA;

    &#xA;-i /storage/emulated/0/Movies/VID_20240512_115128.mp4 -i /storage/emulated/0/Movies/VID_20240512_115116.mp4 -filter_complex "[0:v][1:v]concat=n=2:v=1:a=0[outv]" -map "[outv]" -y /storage/emulated/0/merged_video_2024513_122719.mp4&#xA;

    &#xA;

    (This is my command when i run the code) ??

  • Best way to record a HTML Canvas/WebGL animation server-side into a video ?

    14 décembre 2016, par Abhinav

    I have a set of animations which I can make in Canvas (fabric.js) or WebGL (three.js). I need to record them automatically, server-side, through a script and output a video file.

    The animations include :

    1. Pictures
    2. Videos (with audio)
    3. Other animations/effects

    I have researched a lot during last few months on this.

    Results
    1. User PhantomJS + FFMPEG
    Run HTML Canvas animations on headless browser(PhantomJS) and record with FFMPEG. Here the issue is PhantomJS supports neither WebGL nor Video element. http://phantomjs.org/supported-web-standards.html

    2. Use Websockets to send data back to server using DataURL
    Here again, we will need to run the animations on browser (which we can’t because we have to do everything on server).

    3. Use node-canvas
    This is a library by TJ Holowaychuk which allows rendering HTML Canvas on Node.js. But it has its own limitations plus I haven’t really explored this field much.
    (If someone could shed more light on this library)

    If anyone has done it before or can guide me somewhere useful.
    All we need to do is use some data to create animations and record it into a video, everything on server side.
