• PHP memory issue when executing FFMPEG in CGI module but works from shell in CentOs

  28 mai 2016, par sam rolfe

  I am trying to execute FFMPEG on my VPS server however it is failing due to memory problems. The PHP calls an shell_exec($cmd) on FFMPEG and this throws the memory allocation error. However if I call the exact same FFMPEG command from shell it works.

  Even STRANGER is if I call the php script with the shell_exec($cmd) from shell - then it works.

  I am sorry if I have not phrased this correctly. But I really feel as though this is a memory issue from the PHP being executed in the browser window via the CGI exe - as when it is run from within the shell it is obviously able to maintain the memory level. I am desperate to get this to work and have been researching all week.

  I looked at system("ulimit -a") ;

  core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 1546994 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 16384 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 400 virtual memory (kbytes, -v) 1048576 file locks (-x) unlimited file locks (-x) unlimited

  The PHP is running as a suphp CGI I have set the php.ini memory to 2G, here are the details of things.

  The basic command insude PHP

  $cmd="ffmpeg -hwaccel auto  -i finn.mp4 -y  -pix_fmt yuv410p -s 320x240  -codec:v h264 -c:a copy  -crf 20 -preset slow  0001_finn_test_2.mp4   null >/dev/null 2> ffmpeg_2.log &";

  Output from error log - I can not post the full log as the formatting will not work :

• Show portrait video to landscape on Videojs player as HLS ffmpeg Laravel

  11 décembre 2020, par TwistCode

  I am currently using the ffmpeg library through laravel sdk. For the landscape videos I have no problem with the scaling filters application, but with the portrait videos I need the video to look like the thumbnail below :

  


  

  


  But when I play the video, the player is distorted.

  


  

  


  Note : It should be noted that when I work with horizontal scales, the player looks good, but the video is distorted.

  


  

  


  

  


  this is my PHP Laravel code implementation

  


              FFMpeg::FromDisk('local')->open($this->media)
            ->exportForHLS()
            ->setSegmentLength(6) // optional
            /*
            ->addFormat($lowBitrate, function ($media) {
                $media->addFilter(function ($filters, $in, $out) {
                    $filters->custom($in, 'scale=854x480,setsar=1,setdar=16:9', $out); // $in, $parameters, $out

                });
            })*/
            // Portrait test
            ->addFormat($lowBitrate, function ($media) { 
                $media->addFilter(function ($filters, $in, $out) {
                    // $filters->custom($in, "scale='w=min(720,trunc((480*33/40*dar)/2+0.5)*2):h=min(480,trunc((704*40/33/dar)/2+0.5)*2)',pad='w=720:h=480:x=(ow-iw)/2:y=(oh-ih)/2',setsar='r=40/33'", $out); // $in, $parameters, $out
                    $filters->custom($in, "scale=239:-1", $out); // $in, $parameters, $out
                });
            })
            /*
            ->addFormat($midBitrate, function ($media) {
                $media->scale(1280, 720);
            })
            ->addFormat($highBitrate, function ($media) {
                $media->scale(1920, 1080);
            })*/
            ->save("public/hls/$video->id/$video->hash_name.m3u8");


  


  This is the command that runs at the server level for portrait videos.

  I don't really know if my problem is at the server or frontend level, but I would greatly appreciate any contribution.
