  movdec : handle 0x7fff langcode as macintosh per the specs
  The correct point that seperates ISO and MAC language codes is 0x400
  
  according to the current QT spec. Old QT specs did not list where this
  
  seperation is but apparently only defined the meaning of the first 137.

  libavfilter/dnn/dnn_backendopenvino, tf : check memory alloc non-NULL
  These previously would not check that the return value was non-null
  
  meaning it was susceptible to a sigsegv. This checks those values.

• ffmpeg Getting image or thumbnail from video error

  18 juillet 2013, par eMatsiyana

  i have a simple site on which people upload videos, so i want to generate a simple thumbnail from an uploaded video. i have tried every trick and way to do this from a number of websites but i am failing to make the command run without problems.

  $video = $_FILES['vpopupdropin']["tmp_name"];
  
      $ffmpeg = "C:\\Ffmpeg\\ffmpeg-20130605-git-3289670-win64-static\\bin";
  
      $image = "manu.jpg";
  
      $second = 12;
  
      $size = "150x90";
  
  $command = "$ffmpeg -i $video -an -ss $second -s $size -vcodec mjpeg      $image";
  
  echo $command;
  
      shell_exec($command);
  
  
  
      if(shell_exec($command)){
  
          echo 'okay';
  
          echo &#39;<img src="http://stackoverflow.com/feeds/tag/&#39;.$image.&#39;" style='max-width: 300px; max-height: 300px' /> >&#39;;
  
          }
  
  
  
      else{
  
          echo &#39; Problem&#39;;
  
          }

  i Echoed the the command from PHP and this is what i got :
  C :\Ffmpeg\ffmpeg-20130605-git-3289670-win64-static\bin -i C :\xampp\tmp\php27F1.tmp -an -ss 12 -s 150x90 -vcodec mjpeg manu.jpg Problem

  so i took the Command above and entered it in Cmd and got this error

  [image2 @ 00000000000000003d87580] Could not open file : manu.jpg
  av_interleaved_write_frame() : Input/output error. the uploaded file transfers well to where iam saving it and plays well on the site meaning the file is not corrupt. but the thumbnail command seems to fail, i have even checked the other questions on this site but i seem to fail to get the right solution. the paths in the Command are correct and i have verified that at least
