Url：/project/showfiles.php?group_id=290&package_id=309

tar zxvf lame-398-1.tar.gz

cd lame-398-1

./configure --enable-shared --prefix=/usr

make & make install

2.安装汇编优化器yasm，可能安装x264要用到

/projects/yasm/releases/

tar zxvf yasm-1.3.0.tar.gz

cd yasm-1.3.0

./configure --enable-shared --prefix=/usr

make & make install

3.安装ogg库，libogg

出错提示: *** Could not run Ogg test program, checking why... *** The test program compiled, but did not run. This usually means *** that the run-time linker is not finding Ogg or finding the wrong *** version of Ogg. If it is not finding Ogg, you'll need to set

your *** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point *** to the installed location Also, make sure you have run ldconfig if that *** is required on your system *** *** If you have an old version installed, it is best to remove it,

although *** you may also be able to get things to work by modifying LD_LIBRARY_PATH configure: error: must have Ogg installed!

解决:

# vi /etc/ld.so.conf

include /etc/ld.so.conf.d/*.conf

/usr/local/lib

# ldconfig –v

5.安装x264编码器的库，x264-snapshot

Url：/developers/x264.html

cd x264-snapshot-20141218-2245/

./configure --enable-shared --prefix=/usr

make & make install

6.安装xvid编码器，xvidcore

Url：/downloads/xvidcore-1.3.2.tar.gz

tar zxvf xvidcore-1.3.2.tar.gz

./configure --prefix=/usr

make & make install

7.安装dts库,libdca

Url: /developers/libdca.html

tar xvf libdca-0.0.5.tar.bz2
