• ffmpeg not adding all images when creating video [on hold]

  23 septembre 2013, par travisb

  I am creating a video from 38,179 images. ffmpeg successfully creates a video but only includes the first 20,998 images. I am running Windows 7 64-bit.

  The files are all in the same directory and named 1000000.jpg - 1038179.jpg.

  This is the command I used :

  ffmpeg -f image2 -r 18 -i 1%6d.jpg a.mp4

  How can I get it to include all the images ?

  This is the last screen of output :

  I am working on a project which have the following requirements...

  1. It should upload a video .
  2. then it should verify what type of video file it is i.e flv ,mp4
     etc.
  3. it should also configure its resolution according to our needs.
  4. and then finally save it into a database.

  I have been searching the possible solution for this and learned that ffmpeg could be a solution.But i haven’t been able to learn how to code it.
  Can Somebody please guide me on how to install ffmpeg with Codeignitor from scratch OR some other library which could serve the same purpose .

• php_ffmpeg extension installed, want to know available classes in this extension [on hold]

  25 septembre 2013, par user2808180

  I have successfully installed the php extension "php_ffmpeg" and it is working fine. I tested the extension with class ffmpeg_movie and It shows me complete information of the file.

  But the problem is to convert any uploaded video file to flv. Is there any classes available in the extension 'php_ffmpeg', I would like you to share some sample code for that.

  I will like to stick to php code as I am not sure that I might not get access to the share server shell.

  I also tried exec, on my Windows Based local machine, but I haven't found success beyond "DIR" command.

  Please if you have some knowledge about "php_ffmpeg" extension and classes available in it, with example code or know some resource which include that please help me.

  $return = 1;
  
  $output = array();
  
  
  
  $source = $_SERVER['DOCUMENT_ROOT'] . '/sample.avi';
  
  $target = $_SERVER['DOCUMENT_ROOT'] . '/target.flv';
  
  
  
  
  
  $cmd = "ffmpeg -i {$source} {$target}";
  
  
  
  exec($cmd, $output, $return);
  
  
  
  
  
  echo &#39;<pre>&#39;; print_r($output); echo &#39;</pre>&#39;;
