  test/ : Remove two redundant scripts
  * test_bin.sh looks like it was a personal use script for the original
  
    developer Josh Coalson and referenced directories outside the actual
  
    repository.
  
  * test_wrapper.sh was trivial and un-used.

• Converting Video files in a Azure Webjob with ffMpeg

  13 décembre 2016, par Kevin Phifer

  I’m having trouble using ffMpeg in an Azure webjob.

  I found the following article (How to call ffmpeg.exe to convert audio files on Windows Azure ?) and it is exactly what I want to do, however, I cannot get ffMpeg to execute and it gives no error message.

  To diagnose the problem, I have boiled it down to its essentials by uploading ffMpeg, a video file to convert, and batch file to run it :

  

  The script in run.cmd is simply :

  del output.mp4
  
  ffmpeg -i screencast.wmv -c:v libx264 -r 15 output.mp4

  This works on my personal machine, but ran as a webjob I get results below.

  Edit :
  Additionally, it was suggested that I run using Kudu console. Still no luck :
  

  Solution :
  I ended up needing to run the 32 version of ffMpeg and not the 64 bit. Thanks so much @mathewc !

• How to incorporate screencasting into a rails project

  13 mars 2015, par ruby_newbie

  I am working on a personal project and I want to incorporate screencasting with it. I want the screencast to be able to record the entire screen not just the page in a web browser so I think JS is out as a solution. I have searched and found a few clues but nothing concrete as to how i can make it happen short of learning Java. Here is what I have tried :

  Rmov :https://rubygems.org/gems/rmov I cant get bundler to run bundle with this gem but this has the exact functionality I want. I think it has to do with quicktime being 32 bit but I am not sure. I opened an issue on Github in hopes to resolve it.

  I saw this post : http://devblog.avdi.org/2013/01/21/my-screencasting-process/ which links to this script : https://github.com/avdi/Xcast/blob/master/Xcast
  but I am failing on the require ’highline/system_extensions’ line (require cannot load such file).

  I found this : http://rvideo.rubyforge.org/ but I am still confused as to how to implement it. FFMPEG seems promising though and like it may be the tool I am looking for.

  Does anyone know of a tool that would allow me to do this or a good tutorial that explains this process in detail ? Any help is appreciated and let me know if you need any more info that I can provide.
