centos编译 Compiling FFmpeg on CentOS RHEL Fedora

This guide is based on a minimal installation of the latest CentOS release, and will provide a local, non-system installation of FFmpeg with support for several external encoding libraries. These instructions should also work for recent Red Hat Enterprise Linux (RHEL) and Fedora. This is a non-invasive guide and undoing all steps is simple and is shown at the end of this page.

Get the Dependencies

These are required compiling, but you can remove them when you are done if you prefer (except make; it should be installed by default and many things depend on it).

# yum install autoconf automake cmake freetype-devel gcc gcc-c++ git libtool make mercurial nasm pkgconfig zlib-devel bzip2 

In your home directory make a new directory to put all of the source code into:

mkdir ~/ffmpeg_sources

Compilation & Installation

Note: If you do not require certain encoders you may skip the relevant section and then remove the appropriate ./configure option in FFmpeg. For example, if libvorbis is not needed, then skip that section and then remove --enable-libvorbis from the Install FFmpeg section.

Yasm

Yasm is an assembler used by x264 and FFmpeg.

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

H.264 video encoder. See the H.264 Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with --enable-gpl --enable-libx264.

cd ~/ffmpeg_sources git clone --depth 1 git://git.videolan.org/x264 cd x264

make && make install make distclean

libx265

H.265/HEVC video encoder. See the H.265 Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with --enable-gpl --enable-libx265.

cd ~/ffmpeg_sources hg clone https://bitbucket.org/multicoreware/x265 cd ~/ffmpeg_sources/x265/build/linux cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source make make install 

libfdk_aac

AAC audio encoder.

Requires ffmpeg to be configured with --enable-libfdk-aac (and --enable-nonfree if you also included --enable-gpl).

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

MP3 audio encoder.

Requires ffmpeg to be configured with --enable-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

Opus audio decoder and encoder.

Requires ffmpeg to be configured with --enable-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

Ogg bitstream library. Required by libtheora and libvorbis.

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

Vorbis audio encoder. Requires libogg.

Requires ffmpeg to be configured with --enable-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 

libvpx

VP8/VP9 video encoder.

Requires ffmpeg to be configured with --enable-libvpx.

地址要改为https://github.com/webmproject/libvpx/   git clone https://github.com/webmproject/libvpx

cd ~/ffmpeg_sources git clone --depth 1 https://chromium.googlesource.com/webm/libvpx.git cd libvpx ./configure --prefix="$HOME/ffmpeg_build" --disable-examples make make install make clean 

FFmpeg

cd ~/ffmpeg_sources git clone --depth 1 git://source.ffmpeg.org/ffmpeg 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-libvpx --enable-libx264 --enable-libx265 make && make install && make distclean hash -r 

Compilation is now complete and ffmpeg (also ffprobe, ffserver, lame, and x264) should now be ready to use. The rest of this guide shows how to update or remove FFmpeg.

编译完成后，会：

Tip: Keep the ffmpeg_sources directory and all contents if you intend to update as shown below. Otherwise you can delete this directory.

Updating

Development of FFmpeg is active and an occasional update can give you new features and bug fixes. First, remove the old files and then update the dependencies:

rm -rf ~/ffmpeg_build ~/bin/{ffmpeg,ffprobe,ffserver,lame,vsyasm,x264,x265,yasm,ytasm} # yum install autoconf automake cmake gcc gcc-c++ git libtool make mercurial nasm pkgconfig zlib-devel 

Update Yasm

cd ~/ffmpeg_sources/yasm make distclean git pull 

Then run ./configure, make, and make install as shown in the Install yasm section.

Update x264

cd ~/ffmpeg_sources/x264 make distclean git pull 

Then run ./configure, make, and make install as shown in the Install x264 section.

Update x265

cd ~/ffmpeg_sources/x265 rm -rf ~/ffmpeg_sources/x265/build/linux/* hg update cd ~/ffmpeg_sources/x265/build/linux 

Then run cmake, make, and make install as shown in the Install x265 section.

Update libfdk_aac

cd ~/ffmpeg_sources/fdk_aac make distclean git pull 

Then run ./configure, make, and make install as shown in the Install libfdk_aac section.

Update libvpx

cd ~/ffmpeg_sources/libvpx make clean git pull 

Then run ./configure, make, and make install as shown in the Install libvpx section.

Update FFmpeg

cd ~/ffmpeg_sources/ffmpeg make distclean git pull 

Then run ./configure, make, and make install as shown in the Install FFmpeg section.
