VLC-2.0.2编译过程
缘由：
研究H264的RTP封装时发现大家都使用VLC进行实验，那么我也不搞特殊化，先试试
环境：
ubuntu 10.04LTS
过程：
0）下载最新的vlc：http://www.videolan.org/
1）sudo ./configure
configure: error: Could not find lua. Lua is needed for some interfaces (rc, telnet, http) as well as many other custom scripts.
=》sudo apt-get install lua5.1 liblua5.1-dev
configure: error: Could not find libmad on your system: you may get it from http://www.underbit.com/products/mad/.
=》sudo apt-get install libmad0-dev
configure: error: No package 'libpostproc' found.
=》sudo apt-get install libpostproc-dev
configure: error: Could not find liba52 on your system: you may get it from http://liba52.sf.net/.
=》sudo apt-get install liba52-dev
configure: error: Package requirements (xcb >= 1.6) were not met:Requested 'xcb >= 1.6' but version of XCB is 1.5
=》由于10.04上最新只有1.5.2，所以只能到http://xcb.freedesktop.org/dist/上下载最新的tarball，我下的是1.7的版本，即libxcb-1.7.tar.gz 和xcb-proto-1.7.tar.gz 装好就可以了（先装后者，否则前者装不上）
configure: error: libgcrypt version 1.1.94 or higher not found.
=》sudo apt-get install libgcrypt11-dev
2）sudo make
3）sudo make install
备注：
本人ubuntu上已安装最新的ffmpeg，所以部分包如libavcodec-dev libavformat-dev等已经安装，无须重复
