以前用Ubuntu自帶的源在線安裝ffmpeg過，不過覺得更新比較麻煩，而且每次安裝完要收工鎖定關(guān)鍵的安裝包，要不系統(tǒng)自動升級時會覆蓋你的安裝，相當(dāng)不習(xí)慣！所以，個人認(rèn)為還是用源代碼安裝比較好。
1. 先確認(rèn)某些解碼包沒有安裝，例如H264的，如果安裝了要卸載掉：
sudo apt-get purge ffmpeg x264 libx264-dev
2. 開始安裝：
1) 安裝zlib (可以去www.zlib.net找最新版本裝)
wget http://www.zlib.net/zlib-1.2.3.tar.gz
tar -zxf zlib-1.2.3.tar.gz
cd zlib-1.2.3
make
sudo make install
2) 安裝faad2
wget http://downloads.sourceforge.net/faac/faad2-2.7.tar.gz

make
sudo make install
3) 安裝liba52
wget http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz

./configure
make
sudo make install
4) 安裝libdirac
wget http://downloads.sourceforge.net/dirac/dirac-1.0.2.tar.gz
tar xvfz dirac-1.0.2.tar.gz
cd dirac-1.0.2
./configure
make
sudo make install
5) 安裝faac2
wget http://downloads.sourceforge.net/faac/faac-1.28.tar.gz
tar xvfz faac-1.26.tar.gz
cd faac
./bootstrap
./configure
make
make install
6) 安裝libgsm
wget http://kbs.cs.tu-berlin.de/~jutta/gsm/gsm-1.0.13.tar.gz
tar xvfz gsm-1.0.13.tar.gz
cd gsm-1.0-pl13
make
sudo make install
7) 安裝amrnb (官網(wǎng)：http://www.penguin.cz/~utx/amr)
wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-7.0.0.2.tar.bz2
tar xvfj amrnb-7.0.0.2.tar.bz2
cd amrnb-7.0.0.2
./configure
make
sudo make install
8) 安裝amrwb
wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-7.0.0.3.tar.bz2

tar xzf lame-3.97.tar.gz
cd lame-3.97
./configure
make
sudo make install
10) 安裝libnut (svn獲取源代碼) Library and tools to create NUT multimedia files
svn co svn://svn.mplayerhq.hu/nut/src/trunk libnut
cd libnut
make
sudo make install
11) 安裝libogg
wget http://downloads.xiph.org/releases/ogg/libogg-1.1.4.tar.gz
tar xvf libogg-1.1.4.tar.gz
cd libogg-1.1.4
./configure
make
sudo make install
13) 安裝libtheora (svn獲取)
svn co http://svn.xiph.org/trunk/theora theora

cd yasm-0.8.0
./configure
make
sudo make install
獲取最新版本的x264并編譯安裝，我們在這里通過git命令獲?。?br>cd ~/
git clone git://git.videolan.org/x264.git
開始編譯并安裝
cd x264
./configure --enable-pthread --enable-shared --enable-asm
make
sudo make install
sudo ldconfig
17) 安裝ffmpeg
a. 下載ffmpeg
wget -O ffmpeg.tar.gz "http://git.ffmpeg.org/?p=ffmpeg;a=snapshot;h=124fefe867ef023a89ca4f4cc76e700342286b0d;sf=tgz"
tar -xvzf ffmpeg.tar.gz
cd ffmpeg
b. 這個tar包版本的ffmpeg沒有l(wèi)ibswscale，所以要在ffmpeg目錄下單獨下載:
wget -O libswscale.tar.gz "http://git.ffmpeg.org/?p=libswscale;a=snapshot;h=1842e7d1cc122feea92dcd2d9a9a1adfb397aa24;sf=tgz"
tar -xvzf libswscale.tar.gz
c. 安裝aacPlus庫
它需要libtool和autoconf，所以要先裝：
sudo apt-get install libtool autoconf
d. 然后下載安裝aacPlus (official website : http://tipok.org.ua/node/17)

tar -zxf libaacplus-1.0.4.tar.gz
cd libaacplus-1.0.4
./autogen.sh
./configure
make
sudo make install
e. 下載并安裝aacPlus補丁
wget http://tipok.org.ua/downloads/media/aac+/libaacplus-simple-sample/ffmpeg-patch/ffmpeg-aacp.diff
patch -p1 < ffmpeg-aacp.diff
f. 開始編譯ffmpeg
./configure /

--enable-postproc /
--enable-avfilter /
--enable-avfilter-lavf /
--enable-pthreads /
--enable-libamr-nb /
