# wget http://downloads.sourceforge.net/lame/lame-3.97.tar.gz
# tar xzf lame-3.97.tar.gz
# cd lame-3.97
# ./configure
# make
# make install
# tar xzf lame-3.97.tar.gz
# cd lame-3.97
# ./configure
# make
# make install
8. 安装libx264
此软件包需要用git来获取,所以要先安装git:
# wget http://kernel.org/pub/software/scm/git/git-1.6.2.tar.gz (地址要确认)
# tar zxvf git-1.6.2.tar.gz
# cd git-1.6.2
# ./configure
# make
# make install
# tar zxvf git-1.6.2.tar.gz
# cd git-1.6.2
# ./configure
# make
# make install
然后安装libx264
# /usr/local/bin/git clone git://git.videolan.org/x264.git x264
# cd x264
# ./configure --enable-pthread --enable-shared --disable-asm
# make
# make install
# cd x264
# ./configure --enable-pthread --enable-shared --disable-asm
# make
# make install
8. 安装libnut,该软件需要用svn获取源代码,svn可以直接用yum install svn来装。先下载:
# svn co svn://svn.mplayerhq.hu/nut/src/trunk libnut
下载后代码保存在新建立的libnut目录下,对于64位Linux需要修改配置文件:
# cd libnut
# vi config.mak
# vi config.mak
在最后一个CFLAGS下一行增加:
CFLAGS += -fPIC
然后编译安装:
# make
# make install
# make install
9. 安装libogg
# wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
# tar xvf libogg-1.1.3.tar.gz
# cd libogg-1.1.3
# ./configure
# make
# make install
# tar xvf libogg-1.1.3.tar.gz
# cd libogg-1.1.3
# ./configure
# make
# make install
10. 安装libtheora (svn获取)
# svn co http://svn.xiph.org/trunk/theora theora
# cd theora
# ./autogen.sh
# ./configure
# make
# make install
# cd theora
# ./autogen.sh
# ./configure
# make
# make install
11. 安装libvorbis
# wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.2.0.tar.gz
# tar xvfz libvorbis-1.2.0.tar.gz
# cd libvorbis-1.2.0
# ./configure
# make
# make install
# tar xvfz libvorbis-1.2.0.tar.gz
# cd libvorbis-1.2.0
# ./configure
# make
# make install
12. 安装libxvid
# wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz
# tar xvf xvidcore-1.2.1.tar.gz
# cd xvidcore-1.2.1/build/generic
# ./bootstrap.sh
# ./configure --disable-assembly
# make
# make install
# tar xvf xvidcore-1.2.1.tar.gz
# cd xvidcore-1.2.1/build/generic
# ./bootstrap.sh
# ./configure --disable-assembly
# make
# make install
上面的媒体支持库安装完后,可以设置下环境准备编译FFmpeg了!
13. 修改环境变量
# vi /etc/ld.so.conf
在文件末增加一行:
/usr/local/lib
然后生效之:
# ldconfig
14. 安装FFmpeg
可以通过svn获取,不过文件比较大,所以特别慢:
# svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
# cd ffmpeg
# cd ffmpeg
也可以自己下载:
# http://www.ffmpeg.org/releases/ffmpeg-0.5.tar.bz2
# bzip2 -d ffmpeg-0.5.tar.bz2
# tar -xf ffmpeg-0.5.tar
# cd ffmpeg-0.5
# bzip2 -d ffmpeg-0.5.tar.bz2
# tar -xf ffmpeg-0.5.tar
# cd ffmpeg-0.5
编译(64位系统需要设置PKG_CONFIG_PATH参数):
# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig CFLAGS="-fPIC -m64"
# ./configure --enable-shared \
--enable-gpl \
--enable-nonfree \
--enable-postproc \
--enable-avfilter \
--enable-avfilter-lavf \
--enable-pthreads \
--enable-libamr-nb \
--enable-libamr-wb \
--enable-libdirac \
--enable-libfaac \
--enable-libfaad \
--enable-libfaadbin \
--enable-libmp3lame \
--enable-libnut \
--enable-libtheora \
--enable-libvorbis \
--enable-libx264 \
--enable-libxvid \
--enable-decoder=libx264 \
--enable-encoder=libx264
# make
# make install
# ./configure --enable-shared \
--enable-gpl \
--enable-nonfree \
--enable-postproc \
--enable-avfilter \
--enable-avfilter-lavf \
--enable-pthreads \
--enable-libamr-nb \
--enable-libamr-wb \
--enable-libdirac \
--enable-libfaac \
--enable-libfaad \
--enable-libfaadbin \
--enable-libmp3lame \
--enable-libnut \
--enable-libtheora \
--enable-libvorbis \
--enable-libx264 \
--enable-libxvid \
--enable-decoder=libx264 \
--enable-encoder=libx264
# make
# make install
14. 可能出现的错误:
/usr/include/linux/videodev.h:56: error: syntax error before "ulong"
/usr/include/linux/videodev.h:72: error: syntax error before ‘}‘ token
libavdevice/v4l.c: In function `grab_read_header‘:
libavdevice/v4l.c:75: error: storage size of ‘tuner‘ isn‘t known
libavdevice/v4l.c:133: error: invalid application of `sizeof‘ to incomplete type `video_tuner‘
libavdevice/v4l.c:140: error: invalid application of `sizeof‘ to incomplete type `video_tuner‘
libavdevice/v4l.c:75: warning: unused variable `tuner‘
/usr/include/linux/videodev.h:72: error: syntax error before ‘}‘ token
libavdevice/v4l.c: In function `grab_read_header‘:
libavdevice/v4l.c:75: error: storage size of ‘tuner‘ isn‘t known
libavdevice/v4l.c:133: error: invalid application of `sizeof‘ to incomplete type `video_tuner‘
libavdevice/v4l.c:140: error: invalid application of `sizeof‘ to incomplete type `video_tuner‘
libavdevice/v4l.c:75: warning: unused variable `tuner‘
这可能是源代码videodev.h不是针对次版本Linux写的,标准C没有ulong类型,所以要改成unsigned long
15. 运行ffmpeg -formats,可能出的错误:
ffmpeg: error while loading shared libraries: libavfilter.so.0: cannot open shared object file: No such file or directory
这事没有设置环境路径造成了,增加一个ffmpeg.conf配置文件:
# cd /etc/ld.so.conf.d
# vi ffmpeg.conf
# vi ffmpeg.conf
在文件内写上:
/usr/local/lib
然后确认生效:
# ldconfig
