• Difference between stream level and file level in ffmpeg

  25 avril 2013, par Usama

  Concatenation of files with same codecs with ffmpeg

  Two methods

  Concat demuxer

  Concat protocol

  While the demuxer works at the stream level, the concat protocol works at the file level. Certain files (mpg and mpeg transport streams, possibly others) can be concatenated. This is analogous to using cat on UNIX-like systems or copy on Windows. In general, the demuxer is the better option

  What is the difference between stream level and file level ?

  Thanks in Advance

• using ffmpeg as multiple downloads

  26 avril 2013, par user2321982

  well guys, I'm having problems with my application.
  well I'll explain more, I'm using the plugin uploader uploads multiple videos and I'm using the ffmpeg extension to my php version.

  <code class="echappe-js">&lt;script type=&quot;text/javascript&quot;&gt;<br />
  
  // Convert divs to queue widgets when the DOM is ready<br />
  
  $(function() {<br />
  
      $(&quot;#uploader&quot;).pluploadQueue({<br />
  
          // General settings<br />
  
          runtimes : &amp;#39;gears,flash,silverlight,browserplus,html5&amp;#39;,<br />
  
          url : &amp;#39;upload.php?id=&amp;lt;?= $login_usuario; ?&gt;&amp;amp;name=&amp;lt;?= $name_user; ?&gt;&amp;#39;,<br />
  
          flash_swf_url : &amp;#39;plugins/plupload/plupload.flash.swf&amp;#39;,<br />
  
          containers: &amp;#39;plupload&amp;#39;,<br />
  
          multipart: true,<br />
  
          urlstream_upload: true,<br />

  <br />
  
          max_file_size : &amp;#39;500mb&amp;#39;,<br />

          filters : [<br />
  
              {title : &quot;Video Files&quot;, extensions : &quot;avi,mpg,wmv,flv,3gp,mpeg,mpeg4,mpg4,mp4&quot;}<br />
  
          ],<br />
  
          // Silverlight settings<br />
  
          silverlight_xap_url : &amp;#39;plugins/plupload/plupload.silverlight.xap&amp;#39;<br />
  
      });<br />
  
  <br />
  
      uploader.ini();<br />
  
  <br />
  
   // Client side form validation<br />
  
          $(&amp;#39;form&amp;#39;).submit(function(e) {<br />
  
              var uploader = $(&amp;#39;#uploader&amp;#39;).plupload(&amp;#39;getUploader&amp;#39;);<br />
  
  <br />
  
              // Files in queue upload them first<br />
  
              if (uploader.files.length &gt; 0) {<br />
  
                  // When all files are uploaded submit form<br />
  
                  uploader.bind(&amp;#39;StateChanged&amp;#39;, function() {<br />
  
                      if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {<br />
  
                          $(&amp;#39;form&amp;#39;)[0].submit();<br />
  
                      }<br />
  
                  });<br />
  
  <br />
  
                  uploader.start();<br />
  
              } else<br />
  
                  alert(&amp;#39;You must at least upload one file.&amp;#39;);<br />
  
  <br />
  
              return false;<br />
  
          });<br />
  
      });<br />
  
  &lt;/script&gt;
  
                              
  You browser doesn't have Flash, Silverlight, Gears, BrowserPlus or HTML5 support.
  
  
  

  well he calls javascript in a php file, in case it will upload the videos.

  what I want is to get the length, resolution, file size and take a screenshot of the video randomly, so far so good, the problem is that it only works with only one upload at a time.
  When sending more than one he does the procedure with ffmpeg, besides the most is not taking a screenshot of the video.
  below is my code

  <?php
  
  ini_set('max_execution_time', 300); //300 seconds = 5 minutes
  
  if (!extension_loaded ('ffmpeg') ) exit ( 'ffmpeg não foi carregado!' );

  I removed the code from ffmpeg extension and put an include to that page.
