• Can't get gem 'streamio-ffmpeg' to work in rails 3 w/ windows

  4 janvier 2013, par HelloWorld

  In my gemfile I add the following line...

  gem 'streamio-ffmpeg'

  Then i run bundle, it works fine. When I start my app I get the following error..

  c :/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/activesupport-3.2.9/lib/active_support/dependencies.rb:251:in

  I downloaded ffmpeg from here - http://ffmpeg.zeranoe.com/builds/ and followed these insturctions...http://www.wikihow.com/Install-FFmpeg-on-Windows

  Not sure why it is not working ?

• Add Windows resource file support for shared libraries

  Add Windows resource file support for shared libraries
  Originally written by James Almer <jamrial@gmail.com>
  With the following contributions by Timothy Gu <timothygu99@gmail.com>
  * Use descriptions of libraries from the pkg-config file generation function
  
  * Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
  
  * Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  
    file is distributed" [1].
  
  * Use FFmpeg’s version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
  
  * Only build the .rc files when —enable-small is not enabled.

• How to know if x264 uses multiple processors Windows

  3 décembre 2013, par fessy

  I have Linphone open source application that uses x264 encoder. By default it runs on one thread :

  x264_param_t *params= ..... 
  
  params->i_threads=1;

  I added ability to use all processors :

  long num_cpu=1;
  
  SYSTEM_INFO sysinfo;
  
  GetSystemInfo( &sysinfo );
  
  num_cpu = sysinfo.dwNumberOfProcessors;
  
  params->i_threads=num_cpu;  

  The question is how do I know that during video streaming x264 runs on (in my case) 4 processors ?

  Because from Task Manager -> Performance -> CPU usage history doesn't clear.

  I use windows 7

  Thanks,
