• Update Database After shell_exec() Using FFMPEG/Laravel

  25 avril 2020, par Mike

  I want to update a database record (MySQL) after the FFMPEG process is complete. Normally I would just call a function just after the FFMPEG command, but I needed to add > /dev/null 2>/dev/null & so I didn't have to wait for the FFMPEG process to complete which would mean the REST call would hang for a LONG time and that would cause bad UX for the front-end.

  



  I'm not sure where to begin with it. My first thought is to make a REST request, but maybe calling the method in Laravel directly would be better.

  



  Can I do a curl call after the FFMPEG command ? Or can I call a PHP method ? Or is there a better way ?

  



  PHP FFMPEG Method

  



  private function transcode($movie)
{
    try {
        $name       = 'master.' . $movie->extension;
        $this->path = storage_path('app/public/movies/') . $movie->id . '/';
        $fps        = $this->getFrameRate($name);
        $width      = $this->getVideoWidth($name);
        $height     = $this->getVideoHeight($name);

        // ffmpeg commands
        $c = $this->buildCommand($width, $height, $fps);

        // ffmpeg -  added '> /dev/null 2>/dev/null &' so it will not wait to finish
        $ffmpeg = shell_exec('ffmpeg -i ' . $this->path . $name . ' -progress ' . $this->path . 'transcode.log' . $c . ' > /dev/null 2>/dev/null &');

        return response()->json(['message' => 'transcode initiated'], 200); 

    }
    catch(\Exception $e)
    {
        return response()->json(['error' => $e->getMessage()], 500);
    }
}


  



  Here is the bash curl post idea

  



  $curl = 'curl --data "param1=value1&param2=value2" http://hostname/transcode/complete';

$ffmpeg = shell_exec('ffmpeg -i ' . $this->path . $name . ' -progress ' . $this->path . 'transcode.log' . $c . '; $curl > /dev/null 2>/dev/null &');


  



  I could be going down the wrong path with the above, but I'm trying to move forward with something.

• Streams stop when creating a quad split Multi-viewer using FFMPEG [closed]

  6 avril 2024, par Chris Parker

  Created a FFMPEG script that takes in 4 SRT Live Streams and displays them in a quad split MV. However when I launch this script all 4 SRT streams will play but 3 will pause and 1 will play.

  getting a lot of the below error ;

  


  16:48:49.628704/SRT:RcvQ:w2!W:SRT.qr: @214003038:No room to store incoming packet seqno 649744568, insert offset 7190. Space avail 0/8192 pkts. (TSBPD ready in -12342ms, timespan 6093 ms). GETTIME_MONOTONIC drift 0 ms.


  


  I've tried smaller resolution and adjusting buffer sizes as well as the other flags but I'm not sure what else I can do.
