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
• VLC Docu, Advanced Use

Git的奇技淫巧:see_no_evil:

Git常用命令集合，Fork于tips项目

Git是一个“分布式版本管理工具”，简单的理解版本管理工具：大家在写东西的时候都用过“回撤”这个功能，但是回撤只能回撤几步，假如想要找回我三天之前的修改，光用“回撤”是找不回来的。而“版本管理工具”能记录每次的修改，只要提交到版本仓库，你就可以找到之前任何时刻的状态（文本状态）。

下面的内容就是列举了常用的Git命令和一些小技巧，可以通过"页面内查找"的方式进行快速查询：Ctrl/Command+f。

开卷必读

What is Shadowsocks(R)?

It is a fast and secure socks5 proxy designed to protect your Internet traffic. You can learn more here.
Long story short, it is a proxy that is commonly (and secretly) used in mainland China. People use it to access GFW blocked websites, such as Google, Facebook, etc. You can view a more detailed blocked website list here.

What is BBR?

BBR ("Bottleneck Bandwidth and Round-trip propagation time") is a new congestion control algorithm developed at Google. Congestion control algorithms — running inside every computer, phone or tablet connected to a network — that decide how fast to send data.
