Linux下 FFmpeg 编译安装

FFmpeg是一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。

官网：http://ffmpeg.org

一、FFmpeg安装

安装依赖包：

yum install  libtheora-devel  libvorbis-devel

FFmpeg编译安装：

由于系统不同，会导致依赖也不尽相同，需根据报错信息逐渐安装依赖

wget http://ffmpeg.org/releases/ffmpeg-3.3.2.tar.bz2
tar jxvf ffmpeg-3.3.2.tar.bz2
cd ffmpeg-3.3.2

 

# 如下是个人需要的编译参数，可以根据实际情况增减

./configure --prefix=/usr/local/ffmpeg \
--enable-shared \
--enable-libfdk-aac \
--enable-gpl \
--enable-nonfree \
--enable-postproc \
--enable-avfilter \
--enable-pthreads \
--enable-libmp3lame \
--enable-libtheora \
--enable-libvorbis \
--enable-libx264 \
--enable-libxvid \
--enable-decoder=libx264 \
--enable-encoder=libx264

make && make install

安装后，查看版本

./bin/ffmpeg -version

 

转码：

ffmpeg -i input.mp4 output.avi

二、FFmpeg安装错误解决

有的包下载缓慢，备用下载地址： http://pan.baidu.com/s/1hsEeSNM

• 报错：yasm/nasm not found or too old. Use --disable-yasm for a crippled build

# rpm包存在的话，可以直接yum安装 yasm，没有则编译安装

wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar -zxvf yasm.tar.gz
./configure
make
make install

• 报错：ERROR: libfdk_aac not found

https://sourceforge.net/projects/opencore-amr/files/fdk-aac/
下载fdk-aac-0.1.5.tar.gz 
./configure&& make && make install

• 报错：ERROR: libtheora not found

http://downloads.xiph.org/releases/theora/?C=M;O=D
libtheora-1.2.0alpha1.tar.gz
./configure && make && make install

• 如下报错：

*** Could not run Ogg test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means Ogg was incorrectly installed
*** or that you have moved Ogg since it was installed.

http://downloads.xiph.org/releases/ogg/?C=M;O=D
libogg-1.3.2.tar.gz
./configure && make && make install

 

• 报错：ERROR: libvorbis not found

 

http://downloads.xiph.org/releases/vorbis/
libvorbis-1.3.3.tar.gz

 

　　

 

• 报错：ERROR: libmp3lame >= 3.98.3 not found

http://downloads.sourceforge.net/lame
https://sourceforge.net/projects/lame/files/lame/3.99/,
我下到的是lame-3.99.5.tar.gz
./configure && make && make install

• 报错：ERROR: libx264 not found

 git clone git://git.videolan.org/x264.git
./configure --enable-shared && make && make install

 

• 报错：ERROR: libxvid not found

http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz
cd build/generic/
./configure && make && make install

 

• 库文件找不到时解决：

 

ldd /data/server/ffmpeg/bin/ffmpeg  # 查看依赖库文件，找到no found的库文件
find /  -name libavdevice.so    # 查找库文件位置
vim/etc/ld.so.conf     # 如存在，添加库文件位置
/data/server/ffmpeg/lib/    
ldconfig     # 重新加载，使新库文件生效

 

3.动态链接库

$ sudo vi /etc/ld.so.conf

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

/usr/local/ffmpeg/lib       ///usr/local/ffmpeg 目录是我ffmpeg安装目录，根据你的安装目录改吧

$ sudo ldconfig

 

4.为 Ffmpeg 加入环境变量

vi /etc/profile
加入以下内容:
export PATH="/usr/local/ffmpeg/bin:$PATH"

然后保存并运行source /etc/profile
