Ubuntu下播放加密/有导航的DVD

有些DVD加密或者有导航按钮（比如电视剧等等），要在Linux下播放除了需要播放软件外（如mplayer）还需要安装一些库

以ubuntu11.04为例操作过程如下：

root@steven:~# aptitude show libdvdnav4
Package: libdvdnav4                      
New: yes
State: installed
Automatically installed: yes
Version: 4.1.3-7
Priority: optional
Section: universe/libs
Maintainer: Ubuntu Developers <[email protected]>
Uncompressed Size: 295 k
Depends: libc6 (>= 2.4), libdvdread4
Suggests: libdvdcss2
Description: DVD navigation library
 libdvdnav is a DVD navigation library, which provides an interface to the advanced features of DVDs,
 like menus and naviation. It contains the VM and other parts useful for writing DVD players. It's
 based on Ogle, but was modified to be used by xine and mplayer.

root@steven:~# aptitude show libdvdread4
Package: libdvdread4                     
New: yes
State: installed
Automatically installed: yes
Version: 4.1.3-10ubuntu3
Priority: optional
Section: universe/libs
Maintainer: Ubuntu Developers <[email protected]>
Uncompressed Size: 229 k
Depends: libc6 (>= 2.4)
Recommends: libdvdnav4
Suggests: libdvdcss2, wget, debhelper, fakeroot, build-essential
Description: library for reading DVDs
 libdvdread provides the functionality that is required to access many DVDs. It parses IFO files,
 reads NAV-blocks, and performs CSS authentication and descrambling. 
 
 libdvdread probes for libdvdcss at runtime and if found, will use it to decrypt sections of the DVD
 as necessary. libdvdcss needs to be installed from third-party repositories (see README.Debian),
 it's not included in Debian.

root@steven:~# aptitude install libdvdread4 libdvdnav4

......

root@steven:~# /usr/share/doc/libdvdread4/install-css.sh

Done! Just try it~ 

注意：  网上有说需要安装库libdvdcss，但是ubuntu11.04aptitude 搜索已经没有这个库了，所以执行libdvdread4带的脚本安装css库，具体过程见上面。css相关信息可以参考  http://askubuntu.com/questions/13071/how-can-i-read-every-dvd-even-if-encrypted-by-css-or-other

安装过程可以参考，主要有些不同，例如库的版本，选用的播放器等等  http://www.cyberciti.biz/faq/howto-ubuntu-linux-playback-dvd/
