• Converting a video to .mp4 after upload [on hold]

  18 août 2014, par Colum

  I’ve looked around for a while trying to find an answer to my problem and most point me to using ffmpeg.
  What I want to do is after a user uploads a video, it gets converted to an mp4 file.

  I know ffmpeg can do this, what I cant work out how to do is : install ffmpeg, install ffmpeg on a server i do not own, use ffmpeg to convert uploaded files.

  I have just been told that my server doesnt support ffmpeg, so my QUESTION is, is there a way to do this without ffmpeg ?

• FFMPEG With PHP Upload

  27 décembre 2014, par Will S.

  I’ve created an upload form that uses Ajax to dynamically upload image files to my webserver, and then uses shell_exec and ffmpeg to resize the images (and convert them to jpg, if they are already the correct size), and then save the resulting file. I’m getting really strange behaviour with it. It works about 50% of the time (so far I’ve only tested with JPG and PNG files). Whenever it fails, I get this results :

  /tmp/phpU0pnje: Invalid data found when processing input

  Here’s the PHP code :

  if ($file_info[0] == 'image'){
  
          $image_info = getimagesize($_FILES['upload_media_hidden']['tmp_name'][$i]);
  
          $longest_edge = ($image_info[0] > $image_info[1]) ? $image_info[0] : $image_info[1];
  
          $aspect_ratio = $image_info[0]/$image_info[1];
  
          $aspect_ratio_s = ($image_info[0] > $image_info[1]) ? '200x' . (int)(200/$aspect_ratio) : (int)(200*$aspect_ratio) . 'x200';
  
          $aspect_ratio_m = ($image_info[0] > $image_info[1]) ? '400x' . (int)(400/$aspect_ratio) : (int)(400*$aspect_ratio) . 'x400';
  
          $aspect_ratio_l = ($image_info[0] > $image_info[1]) ? '700x' . (int)(700/$aspect_ratio) : (int)(700*$aspect_ratio) . 'x700';
  
  
  
          if ($longest_edge > 200){
  
                  $file_s = shell_exec('ffmpeg -i ' . escapeshellarg($_FILES['upload_media_hidden']['tmp_name'][$i]) . ' -f image2 -s ' . $aspect_ratio_s . ' - 2>&1');
  
          }
  
  
  
        ................more processing below

  So the ffmpeg command essentially looks like this :

  ffmpeg -i ’SOMEFILE.jpg’ -f image2 -s 400x200 -

  When I run that command in bash to the actual file (not the temporary file when I upload it to my form), it works fine. I’m guessing the issue is with the pipe, but I’m not sure. Any ideas ?

  Thanks !

  Update :
  When I run this code :

  if ($file_info[0] == 'image'){
  
          $image_info = getimagesize($_FILES['upload_media_hidden']['tmp_name'][$i]);
  
          $longest_edge = ($image_info[0] > $image_info[1]) ? $image_info[0] : $image_info[1];
  
          $aspect_ratio = $image_info[0]/$image_info[1];
  
          $aspect_ratio_s = ($image_info[0] > $image_info[1]) ? '200x' . (int)(200/$aspect_ratio) : (int)(200*$aspect_ratio) . 'x200';
  
          $aspect_ratio_m = ($image_info[0] > $image_info[1]) ? '400x' . (int)(400/$aspect_ratio) : (int)(400*$aspect_ratio) . 'x400';
  
          $aspect_ratio_l = ($image_info[0] > $image_info[1]) ? '700x' . (int)(700/$aspect_ratio) : (int)(700*$aspect_ratio) . 'x700';
  
  
  
          if ($longest_edge > 200){
  
                  move_uploaded_file($_FILES['upload_media_hidden']['tmp_name'][$i],'/tmp/TEST.jpg');
  
                  system('ffmpeg -i /tmp/TEST.jpg -f image2 -s ' . $aspect_ratio_s . ' - 2>&1');
  
  
  
                  $file_s = system('ffmpeg -i ' . escapeshellarg($_FILES['upload_media_hidden']['tmp_name'][$i]) . ' -f image2 -s ' . $aspect_ratio_s . ' - 2>&1');

  I get this result from php :

  /tmp/phpxqYzHN: No such file or directory

  So it seems to work if I move the file first ? It’s really important that I don’t have any extra disk io, so this solution wouldn’t be acceptable...

  SOLUTION :
  So the problem was that ffmpeg was not able to recognize the input file type, since PHP’s tmp files don’t end with an extension (seems like a bug that ffmpeg looks at the extension rather than the internal mime type/headers). The solution was that I needed to add "-f image2" to the beginning of my command, so it ended up looking something like this :

  ffmpeg -f image2 -i '/tmp/PHP_TMP_FILE' -f image2 -s 400x200 -

  Hopefully this will save someone the many hours it took me to figure this out...
