• php video upload and ffmpeg won't create a thumbnail

  18 mai 2020, par Azzo

  I am trying to make a video upload feature for my project. But I have a problem with ffmpeg section. ffmpeg is already installed on my server. But i can not get any thumbnail. I have try to create thumbnail using the following code :

  



  $videoa = exec("/usr/bin/ffmpeg  -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4 2>&1");
$videob = exec("/usr/bin/ffmpeg  -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");


  



  But i ge this when use var_dump(); for var_dump($videoa); and var_dump($videob);

  



  


  string(74) "https://mywebsite.com/uploads/video/ey1kXNew_video.flv :
 Input/output error" string(0) ""

  


  



  Also if i use the shell_exec like this :

  



  $videoa = shell_exec("/usr/bin/ffmpeg  -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4");
$videob = shell_exec("/usr/bin/ffmpeg  -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");


  



  and the var_dumps() giving me NULL NULL.

  



  Please help me where am I wrong.

  



  And here is my full video upload code :

  



  $valid_formats = array("mp4","MP4","flv");
            if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST") {
               $name = $_FILES['uploading']['name'];
               $size = $_FILES['uploading']['size'];
               if(strlen($name)) {
                   $ext = strtolower(pathinfo($name, PATHINFO_EXTENSION)); 
                   $name = alphaID(microtime(true) * 10000).'_video';
                   if(in_array($ext,$valid_formats)) {
                   if($size<(50024*50024)) {
                      $GetVideoName = $name;
                      $video_ext=$ext;
                       $tmp = $_FILES['uploading']['tmp_name'];
                       if(move_uploaded_file($tmp, $videoPath.$GetVideoName.'.'.$video_ext)) {
                           $videoUrlp = $base_url.'uploads/video/'.$GetVideoName;
                           $videoa = exec("/usr/bin/ffmpeg  -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4 2>&1");
                           $videob = exec("/usr/bin/ffmpeg  -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");
                           echo var_dump($videoa);
                           echo var_dump($videob);

                        } else {
                            echo "Fail upload folder with read access.";
                        }
                     } else
                        echo "Image file size max 1 MB";                    
                     } else
                        echo "invalidvieo"; 
                 } else
                    echo "Please select image..!";
                 exit;
              }


  



  I have tested also like this way :

  



  echo exec("/usr/bin/ffmpeg -i $videoUrlp.flv -ar 22050 -ab 32 -f flv -s 780x400 $videoUrlp.$video_ext");
echo exec("/usr/bin/ffmpeg -i $videoUrlp.$video_ext -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $videoUrlp.png 2>&1");


  



  and I see the following echo

  



  video:71kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000000%

  



  and another try then I get this note : https://mywebsite.com/uploads/video/1547892356_video.flv : Connection refused

  



  echo exec("/usr/bin/ffmpeg -i $videoUrlp.flv -ar 22050 -ab 32 -f flv -s 780x400 $videoUrlp.$video_ext");
echo exec("/usr/bin/ffmpeg -i $videoUrlp.$video_ext -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $videoUrlp.png 2>&1");


  



  Here is last shell_exec Output :

  



   $local = 'https://website.com/uploads/video/'.$GetVideoName.'.'.$video_ext;
 $localTumb = 'https://website.com/uploads/video/'.$GetVideoName.'.png';
 echo shell_exec("/usr/bin/ffmpeg -i $local -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $localTumb 2>&1");

• using ffprobe to create numeric output

  8 juin 2015, par edwardsmarkf

  easy newbie question - i hope this is an appropriate forum

  i have been using this npm module : npmjs(dot)com/package/waveform-util

  and this npm module creates waveform numeric output such as this below :

  [0,0.0062,0.0688,0.2524,0.2691,0.2645,0.1594,0.1397,0.1672

  however, this module does not seem reliable and has not been maintained for a couple of years now. the module describes itself as a "tiny wrapper around ffprobe".

  my question - what would the command line look like to produce such output ?

  thank you all in advance.

  UPDATE :

  i have carefully looked at :

  ffprobe   -show_packets  -show_data  -show_streams  -i  file.opus ;

  but i am not seeing any value here that reflects the audio volume level, or i am seeing but not recognizing it.
