  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)).

• 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 !

• tag refuses to play mp4 video

  5 janvier 2015, par MightyPork

  I have a video I want to embed using the html5 video tag :

  • https://dl.dropboxusercontent.com/u/64454818/TMP/P6135199.MOV

  I’ve converted it using ffmpeg :

  ffmpeg -i P6135199.MOV -vcodec libx264 -acodec aac helios.mp4

  FFMPEG output :

  And I try to embed it as follows :

  <video src="helios.mp4" controls="controls">Get a better browser!</video>

  However, Chrome doesn’t play the video, only offers to download it (same as it did before I converted the video). Firefox has the same problem.

  I’ve tested and other mp4 files (from my phone) play just fine.

  What’s the problem ? Did I convert it wrong ?
