• AJAX won't execute all of the php code

  27 septembre 2016, par hermanboy07

  I want a progressbar to be shown while a video-file is being uploaded. I’m using JS and AJAX to track progress of the file-upload php, and send the file. The php file contains a ffmpeg command that grabs some frames from the video. Essentially the php file creates a random folder, and puts both the video and the frames in it. when the php is called by if(isset($_FILES['file'])) it works just fine. But when i try to use AJAX it only uploads the video, but ignores the ffmpeg command and mysql_query.

  Javascript :

  function uploadFile(){
  
          var file = _("file1").files[0];
  
          var formdata = new FormData();
  
          formdata.append("file1", file);
  
          var ajax = new XMLHttpRequest();
  
          ajax.upload.addEventListener("progress", progressHandler, false);
  
          ajax.open("POST", "upload.php");
  
          ajax.send(formdata);

  Upload.php

          $name = $_FILES['file1']['name'];
  
          $type = explode(".",$name);
  
          $type = end($type);
  
          $tmp = $_FILES['file1']['tmp_name'];
  
          $uploadOk = 1;
  
          $exp = explode(".",$name);
  
          $filename = rand().$exp[0];
  
          $path = "videos/" . $filename . "/" . $name;
  
          $ffmpeg = "/usr/local/bin/ffmpeg";
  
          $size = "320x180";
  
  
  
          if($type != 'mp4' && $type != 'MP4'){
  
  
  
            $message = "Only mp4 format is supported!";
  
            $uploadOk = 0; 
  
  
  
          }else{
  
  
  
            mkdir("videos/".$filename);
  
  
  
            // ffmpeg function 
  
            for($num = 1; $num <= 15; $num++){
  
            $interval = $num * 3;
  
            shell_exec("$ffmpeg -i $tmp -an -ss $interval -s $size /videos/$filename/thumb$num.png");}
  
  
  
            move_uploaded_file($tmp, $path);
  
            mysql_query("INSERT INTO table (name, url) VALUES('$name', '$path')");

  Why dosen’t AJAX execute the complete php ?

• How do I remove ffmpeg video watermark code ?

  26 juillet 2019, par D. Messier

  Trying to remove the code that adds a watermark to some of our videos, but can’t find the correct solution

  Working with pre-existing code. I am unfamiliar with Bash and ffmpeg. We are trying to remove the code that adds a watermark to certain videos. There are plenty of examples on how to add the watermark. But using them to figure out how to remove it has been unsuccessful.

  Original Code

  FFREPORT=file=$folder/ffmpeg.log:level=40 ~/tools/ffmpeg/ffmpeg -ss $startTime -i $folder/0 -i assets/watermark.png -filter_complex "[0:v]scale='if(gt(iw,ih),$size1w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size1h)'[bg];[bg][1:v]overlay=20:(main_h-overlay_h-20),split=5[in1][in2][in3][in4][in5];[in1]scale='if(gt(iw,ih),$size1w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size1h)'[out1];[in2]scale='if(gt(iw,ih),$size2w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size2h)'[out2];[in3]scale='if(gt(iw,ih),$size3w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size3h)'[out3];[in4]scale='if(gt(iw,ih),$size4w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size4h)'[out4];[in5]scale='if(gt(iw,ih),$size4w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size4h)'[out5]" \

  Attempted Change

  I removed -i assets/watermark.png and [bg];[bg][1:v]overlay=20:(main_h-overlay_h-20),

  FFREPORT=file=$folder/ffmpeg.log:level=40 ~/tools/ffmpeg/ffmpeg -ss $startTime -i $folder/0 -filter_complex "[0:v]scale='if(gt(iw,ih),$size1w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size1h)';split=5[in1][in2][in3][in4][in5];[in1]scale='if(gt(iw,ih),$size1w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size1h)'[out1];[in2]scale='if(gt(iw,ih),$size2w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size2h)'[out2];[in3]scale='if(gt(iw,ih),$size3w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size3h)'[out3];[in4]scale='if(gt(iw,ih),$size4w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size4h)'[out4];[in5]scale='if(gt(iw,ih),$size4w,trunc(oh*a/2)*2)':'if(gt(iw,ih),trunc(ow/a/2)*2,$size4h)'[out5]" \

  The error I’m getting is "Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_split_1"
