CentOS搭建FFMPEG环境实现MP4格式转m3u8格式

一、实验环境:centOS

二、步骤


1、使用yum安装ffmpeg的依赖文件

此步骤一般不会有什么问题,就算以前安装过下面的某些软件,也不会重复安装

yum install autoconf automake cmake freetype-devel gcc gcc-c++ git libtool make mercurial nasm pkgconfig zlib-devel -y

2、安装ffmpeg的功能模块

下面这些功能模块是可以选择的,当需要ffmpeg实现这些功能时,就可以选择安装或者不安装,因为我需要实现的是mp4转m3u8格式功能,必须增加libx264模块

Yasm :yasm是x264和ffmpeg必须要依赖的模块

cd ~/ffmpeg_sources
git clone --depth 1 git://github.com/yasm/yasm.git
cd yasm
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install
make distclean

libx264:

cd ~/ffmpeg_sources
git clone --depth 1 git://git.videolan.org/x264
cd x264
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
make
make install
make distclean

libfdk_aac

cd ~/ffmpeg_sources
git clone --depth 1 git://git.code.sf.net/p/opencore-amr/fdk-aac
cd fdk-aac
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
make distclean

libmp3lame

cd ~/ffmpeg_sources
curl -L -O http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
tar xzvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --disable-shared --enable-nasm
make
make install
make distclean

libopus

cd ~/ffmpeg_sources
git clone git://git.opus-codec.org/opus.git
cd opus
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
make distclean

libogg

cd ~/ffmpeg_sources
curl -O http://downloads.xiph.org/releases/ogg/libogg-1.3.2.tar.gz
tar xzvf libogg-1.3.2.tar.gz
cd libogg-1.3.2
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
make distclean

libvorbis

cd ~/ffmpeg_sources
curl -O http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.4.tar.gz
tar xzvf libvorbis-1.3.4.tar.gz
cd libvorbis-1.3.4
LDFLAGS="-L$HOME/ffmeg_build/lib" CPPFLAGS="-I$HOME/ffmpeg_build/include" ./configure --prefix="$HOME/ffmpeg_build" --with-ogg="$HOME/ffmpeg_build" --disable-shared
make
make install
make distclean

FFmpeg

下面这个步骤是官网给出来的,执行下面这个步骤的时候出了个问题,用git命令去拿ffmpeg源码的时候拿不到,可能是跟网络问题,故而我是直接下载最新的版本来用的,我下载的是2.8.4,其他步骤都是一样

cd ~/ffmpeg_sources
git clone --depth 1 http://source.ffmpeg.org/git/ffmpeg.git  
cd ffmpeg
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --pkg-config-flags="--static" --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libx264
make
make install
make distclean
hash -r

到这里,ffmpeg就编译安装完成了。


三、测试

我在/tmp/mp4/目录下面放了一个 test.mp4文件,执行下面命令

cd /tmp/mp4/
ffmpeg -i test.mp4 -c:v libx264 -c:a aac -strict -2 -f hls -hls_time 15 -hls_list_size 0 test.m3u8

成功执行后的显示

[root@dev1 mp4]# ffmpeg -i test.mp4 -c:v libx264 -c:a aac -strict -2 -f hls -hls_time 15 -hls_list_size 0 test.m3u8
