  • FFMpeg undefined reference to get_buffer

    I'm trying to upgrade the FFMpeg source used with one of our projects but get_buffer has gone away. I'm not 100% sure on which method to replace it with. Here are two contexts in which its used, any help is appreciated.

    I look forward to hearing from you soon,

  • 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 />

    <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 />

                       }<br />
                   });<br />
    <br />
                   uploader.start();<br />
               } else<br />
                   alert(&amp;#39;You must at least upload one file.&amp;#39;);<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
