無意間發現了一個非常優秀的開源流媒體系統：OBS ( Open Broadcaster Software ) 

執行截圖：

該軟體是基於MFC的，下載原始碼後一次性就可以編譯通過，使用很簡單。

使用了以下開源庫：

  x264                   - H.264編碼庫
  libmp3lame             - MP3編碼庫
  libfaac                - AAC編碼庫
  librtmp                - RTMP協議工具庫
  libsamplerate          -音訊重取樣庫

英文介紹原文：

Open Broadcaster Software is free and open source software for the purposes of streaming live media content to the internet or to video files.
Originally I just made it for myself because I thought "why should I pay a subscription for software I could probably write myself?"
..And so, I did. And it evolved into somewhat of a monster of a project. And that's pretty much the end of the story.
I hope people can make use of this application, or otherwise learn something from it. I'm having a ton of fun writing this software and am learning much in the process. Overall it's been an excellent experience.
