云

IaaS指提供系统（可以自己选）或者储存空间之类的硬件，软件要自己手动装；PaaS提供语言环境和框架（可以自己选）；SaaS只能使用开发好的软件（卖软件本身）；BaaS一般类似于非关系数据库，但各家不通用，有时还有一些其它东西。

Live Transcoding

This is a collection of working commandline examples to show how one could use FFMpeg and VLC for live transcoding of video streams. All examples have been tested on OSX 10.7.5 with FFMPeg 1.1.3 and VLC 2.0.5 in early 2013.

• FFMpeg, Muxers, Encoders, Protocols
• FFMPEG multiple outputs
