• Creating a movie from multiple .png files

  21 octobre 2014, par QuantumFool

  I’ve got quite a few .png files, and I need to create a movie out of them. So, I’m going through this tutorial which uses ffmpeg :

  http://www.miscdebris.net/blog/2008/04/28/create-a-movie-file-from-single-image-files-png-jpegs/

  When I go to type the first line (sudo apt-get install ffmpeg), in Terminal and enter my password as appropriate, I get :

  Reading package lists... Done
  
  Building dependency tree       
  
  Reading state information... Done
  
  Package ffmpeg is not available, but is referred to by another package.
  
  This may mean that the package is missing, has been obsoleted, or
  
  is only available from another source
  
  
  
  E: Package 'ffmpeg' has no installation candidate

  That’s funny ; I installed the latest version manually this morning ! Anyway, I proceed with the instructions assuming ffmpeg is installed properly (I’m looking at the file where it downloaded to, so that can’t be the issue) :

  cd Downloads
  
  cd python-meep
  
  cd Images
  
  ffmpeg -qscale 4 -r 20 -b 9600 -i Image%03d.png movie.mp4

  To my surprise, I get :

  ffmpeg: command not found

  I just installed it ! Furthermore, I dragged my manual installation folder into the very same directory with the pictures ! What’s going on ?

  Thanks !

  I am trying to integrate splicer into my asp.net MVC Project.I had a problem with Splicer code (which create video from images) works at local but gives the following error at server :

  Retrieving the COM class factory for component with CLSID 78530B75-61F9-11D2-8CAD-00A024580902 failed due to the following error : 80040154 Class not registered (Exception from HRESULT : 0x80040154 (REGDB_E_CLASSNOTREG)).

  Here is the link of my test sample

  I know this question is already asked on this form and other forms but that doesn’t resolve my issue

  Please help to solve the error

• Why am I getting an error for stream #0.1 ?

  30 juillet 2014, par Rob Avery IV

  I’m converting videos using ffmpeg-php. Here is my code :

      // Set our source file
  
      $srcFile = $uploadFilm.".".$film_type;
  
      $destFile = $uploadFilm;
  
      $ffmpegPath = "ffmpeg";
  
  
  
      // Create our FFMPEG-PHP class
  
      $ffmpegObj = new ffmpeg_movie($srcFile);
  
  
  
      // Save our needed variables
  
      $srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
  
      $srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
  
      $srcFPS = $ffmpegObj->getFrameRate();
  
      if($ffmpegObj->hasAudio()){
  
          $srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
  
          $srcAR = $ffmpegObj->getAudioSampleRate();
  
      }else{
  
          $srcAB = 0;
  
          $srcAR = 0;
  
      }
  
  
  
      // Call our convert using exec()
  
      //$command = $ffmpegPath . " -i " . $srcFile . " -ar " . $srcAR . " -ab " . $srcAB . "k -f flv -s " . $srcWidth . "x" . $srcHeight . " " . $destFile;
  
      //$command = "whoami";
  
      $command = $ffmpegPath . ' -i ' .'"'. $srcFile . '" -ar ' . $srcAR . ' -ab ' . $srcAB . 'k -f flv -s ' . $srcWidth . 'x' . $srcHeight . ' "' . $destFile . '" 2>&1';
  
      $outputCommand = array();
  
      $status = 1;
  
      exec($command, $outputCommand, $status);

  The output gives out this error at the end :

  Error while opening encoder for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height

  I know that both $srcAB and $srcAR have values because this is the command this being ran :

  ffmpeg -i source -ar 48000 -ab 160k -f flv -s 1920x1080 destination

  Of course, after the command is executed, the "convert video" has a size 0, which means it didn’t convert it.

  What am I missing here ?
