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.bz2tar jxvf ffmpeg-3.3.2.tar.bz2cd 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=/data/server/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=libx264make && 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.gztar -zxvf yasm.tar.gz./configuremakemake 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=Dlibtheora-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.

• 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
