How do I install xine

1 First I download the two packages xine-lib-1.1.4.tar.bz2 and xine-ui-0.99.4.tar.gz frome the official website.
2 Then extract them by tar xjfv xine-lib-1.1.4.tar.bz2 and tar zxvf xine-ui-0.99.4.tar.gz
3 OK,Let's begin install xine.Install xine-lib-1.1.4 first.
cd xine-lib-1.1.4
./configure && make && make install && make clean
This will take a long long time ,don't lose your patience.
After it complete,remember run the command ldconfig,then
cd xine-ui-0.99.4
./configure && make && make install && make clean
4 All complete,so I open xine and play a movie of rmvb.
wow,it's really beautiful,I think it is better than mplayer.But latter I
find no sound.After googling,I solving this problem.What did I do?
Look at the following.
5 gedit ~/.xine/catalog.cache
find decoder_priority In this pragraph /usr/lib/xine/plugins/1.1.4/xineplug_decode_real_audio.so
.It's default value is 5,change it into 10.
6 Open xine again,it can play rmvb and mp3 well.In a word ,perfect.

let opera use fcitx to input Chinese

gedit opera
Add export QT_IM_MODULE=XIM after the #!/bin/sh so it will look like this
#!/bin/sh

export QT_IM_MODULE=XIM
# Use this if you don't want to install Opera to any special location,
# but execute it from the extracted package or current location.
