下载FFmpeg和libx264的包
ffmpeg-2.4.1.tar.bz2 last_x264.tar.bz2
libx264需要yasm,所以先安装yasm
apt-get install yasm
然后安装libx264
aptitude install libx264-dev
也可以手动安装libx264(原先libx264在ubuntu的软件源里是没有的只能手动安装,现在有了就可以不用手动安装了)
解压缩libx264
tar -xjvf last_x264.tar.bz2
安装libx264
./configure --enable-shared --enable-pic
make
make install
然后安装ffmpeg,ffmpeg有许多依赖包,需要一个一个先安装
1. libfaac
aptitude install libfaac-dev
2. libmp3lame
aptitude install libmp3lame-dev
3. libtheora
aptitude install libtheora-dev
4. libvorbis
aptitude install libvorbis-dev
5. libxvid
aptitude install libxvidcore-dev
6. libxext
aptitude install libxext-dev
7. libxfixes
aptitude install libxfixes-dev
依赖包安装完后,安装ffmpeg
先解压缩ffmpeg
tar -xjvf ffmpeg-2.4.1.tar.bz2
然后编译安装
./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-pthreads --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-x11grab --enable-libvorbis
make
make install
在ubuntu 12.04上安装ffmpeg后
命令ffmpeg不管用
把编译后文件中/usr/local/ffmpeg/bin/ffmpeg文件复制到/usr/ bin当中
使用命令成功
ffmpeg -version
ffmpeg默认安装目录为“/usr/local/lib”,有些64位系统下软件目录则为“/usr/lib64”,编译过程中可能会出现“ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory”等类似的错误,解决办法是建立软链接或者移动库文件到相应的目录:
ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0
mv /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0
1. ERROR: libopenjpeg not found
http://code.google.com/p/openjpeg/downloads/detail?name=openjpeg-1.5.1.tar.gz&can=2&q=
下载openjpeg-1.5.1的代码,注意不要下载openjpeg-2.0的,否则ffmpeg跟openjpeg的接口不支持,编译会处错误。
configure
make,make install
找到头文件是在/usr/local/include/openjpeg-1.5.1下面,而ffmpeg在连接的时候,其实是/usr/local/include,所以提示说“ERROR: libopenjpeg not found”。将/usr/local/include/openjpeg-1.5.1下面的头文件“openjpeg.h”拷贝到/usr/local/include下面。
1,x264也是有这个问题,x264.h这个文件要放在/usr/local/include下,而不是在/usr/local/下单独建个子目录放。 其他的库都是在make install的时候自己建的子文件夹。
需要将libx264的库文件拷贝到/usr/local/lib下
或者直接在configure的时候,改变路径,如下所示:
./configure --includedir=/usr/local/include --libdir=/usr/local/lib --enable-shared
即可。
2. ERROR:libfdk_aac not found
http://sourceforge.net/projects/opencore-amr/?source=directory
下载fdk-aac-0.1.1.tar.gz
执行
configure
make
make install
3. ERROR:libilbc not found
https://github.com/dekkers/libilbc
git clone git://github.com/dekkers/libilbc.git
解压
安装cmake,如下所示
sudo apt-get install cmake
cd build
cmake .. (这里的..意思是,如果是一个.表示CMakeLists.txt在当前路径下,两个..表示CMakeLists.txt在上一层目录下)
cmake install ..
make (在build/bin下会找到可执行文件。)
make install (将生成的库拷贝到linux相关目录下)
4. ERROR: libmp3lame >= 3.98.3 not found
sudo apt-get install libmp3lame-dev
5. ERROR: libopencore_amrnb not found

(5) git chone git://git.videolan.org/x264.git
configure

(6) ERROR: libvo_aacenc not found

(9)编译 ffplay 需要 libsdl1.2-dev 库:sudo apt-get install libsdl1.2-dev (10)
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file
Solution:
Search the file libavdevice.so.52 on the server using the ‘find’ command
1# find / -name libavdevice.so.52
You need to add the path to the directory the file is in, in the ‘ld.so.conf’ file. If for example the file is located under “/usr/local/lib” directory, execute
1# vi /etc/ld.so.conf
and add the following at the bottom of the file
/usr/local/lib
加入自己编译ffmpeg的路径/lib
执行ldconfig
