This guide for supported releases of Ubuntu, Debian, andLinux Mint will provide a local install of the latest FFmpeg tools and libraries including several external encoding and decoding libraries (codecs). This will not interfere with repository packages.

You may also refer to the Generic FFmpeg Compilation Guide for additional information.

Recent ​static builds are also available for lazy people or those who are unable to compile.

Get the Dependencies

Copy and paste the whole code box for each step.

sudo apt-get updatesudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev libgpac-dev \  libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libx11-dev \  libxext-dev libxfixes-dev pkg-config texi2html zlib1g-devmkdir ~/ffmpeg_sources

Notes:

• Server users can omit the ffplay and x11 dependencies: libsdl1.2-dev libva-dev libvdpau-dev libx11-dev libxext-dev libxfixes-dev.
• Lucid lacks the package libva-dev. This can be ignored.

---

Compilation & Installation

You can compile ffmpeg to your liking. 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 libopus is not needed, then skip that section and then remove--enable-libopus from the Install FFmpeg section.

This guide is designed to be non-intrusive and will create several directories in your home directory:

• ffmpeg_sources – Where the source files will be downloaded.
• ffmpeg_build – Where the files will be built and libraries installed.
• bin – Where the resulting binaries (ffmpeg, ffplay,ffserver, x264, and yasm) will be installed.

You can easily undo any of this as shown in Reverting Changes Made by This Guide.

Yasm

An assembler for x86 optimizations used by x264 and FFmpeg. Highly recommended or your resulting build may be very slow.

If your repository offers a yasm package ≥ 1.3.0 then you can install that instead of compiling:

sudo apt-get install yasm

Otherwise you can compile:

cd ~/ffmpeg_sourceswget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gztar xzvf yasm-1.3.0.tar.gzcd yasm-1.3.0./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"makemake installmake 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.

If your repository offers a libx264-dev package ≥ 0.118 then you can install that instead of compiling:

sudo apt-get install libx264-dev

Otherwise you can compile:

cd ~/ffmpeg_sourceswget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2tar xjvf last_x264.tar.bz2cd x264-snapshot*PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-staticPATH="$HOME/bin:$PATH" makemake installmake distclean

libfdk-aac

AAC audio encoder. See the AAC Audio Encoding Guide for more information and usage examples.

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

sudo apt-get install unzipcd ~/ffmpeg_sourceswget -O fdk-aac.zip https://github.com/mstorsjo/fdk-aac/zipball/masterunzip fdk-aac.zipcd mstorsjo-fdk-aac*autoreconf -fiv./configure --prefix="$HOME/ffmpeg_build" --disable-sharedmakemake installmake distclean

libmp3lame

MP3 audio encoder.

Requires ffmpeg to be configured with --enable-libmp3lame.

If your repository offers a libmp3lame-dev package ≥ 3.98.3 then you can install that instead of compiling:

sudo apt-get install libmp3lame-dev

Otherwise you can compile:

sudo apt-get install nasmcd ~/ffmpeg_sourceswget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gztar xzvf lame-3.99.5.tar.gzcd lame-3.99.5./configure --prefix="$HOME/ffmpeg_build" --enable-nasm --disable-sharedmakemake installmake distclean

libopus

Opus audio decoder and encoder.

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

If your repository offers a libopus-dev package ≥ 1.1 then you can install that instead of compiling:

sudo apt-get install libopus-dev

Otherwise you can compile:

cd ~/ffmpeg_sourceswget http://downloads.xiph.org/releases/opus/opus-1.1.tar.gztar xzvf opus-1.1.tar.gzcd opus-1.1./configure --prefix="$HOME/ffmpeg_build" --disable-sharedmakemake installmake distclean

libvpx

VP8/VP9 video encoder and decoder. See the VP8 Video Encoding Guide for more information and usage examples.

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

cd ~/ffmpeg_sourceswget http://webm.googlecode.com/files/libvpx-v1.3.0.tar.bz2tar xjvf libvpx-v1.3.0.tar.bz2cd libvpx-v1.3.0PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --disable-examplesPATH="$HOME/bin:$PATH" makemake installmake clean

ffmpeg

Note: Server users can omit --enable-x11grab (this option is for x11 screen grabbing).

cd ~/ffmpeg_sourceswget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2tar xjvf ffmpeg-snapshot.tar.bz2cd ffmpegPATH="$HOME/bin:$PATH" 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="$HOME/bin" \  --enable-gpl \  --enable-libass \  --enable-libfdk-aac \  --enable-libfreetype \  --enable-libmp3lame \  --enable-libopus \  --enable-libtheora \  --enable-libvorbis \  --enable-libvpx \  --enable-libx264 \  --enable-nonfree \  --enable-x11grabPATH="$HOME/bin:$PATH" makemake installmake distcleanhash -r

Conclusion

Installation is now complete and ffmpeg is now ready for use. Your newly compiled FFmpeg programs are in~/bin. To use it:

• Navigate to ~/bin and execute the binary: cd ~/bin && ./ffmpeg -i ~/input.mp4 ~/videos/output.mkv (notice the./)
• Or you can use the full path to the binary: /home/yourusername/bin/ffmpeg -i ../input.mp4 ../videos/output.mkv
• Or if you simply want to just issue the ffmpeg command and have your shell use your compiled binary see the Persistent Environment Variables section below.

Persistent Environment Variables

You can tell your shell (assuming you're using Bash) to persistently use your newffmpeg in ~/bin. The first command will allow you to simply runman ffmpeg to get the FFmpeg man pages. The second command will source ~/.profile which will add ~/bin to your $PATH. In short, the following commands will allow you to simply typeffmpeg and man ffmpeg in your terminal and they will "just work":

echo "MANPATH_MAP $HOME/bin $HOME/ffmpeg_build/share/man" >> ~/.manpath. ~/.profile

Note:

• This may reset custom variables in the current shell session.
• This assumes you are using the default ~/.profile (and therefore ~/.bashrc).
• This assumes you are using Bash shell.
• Sourcing the default ~/.profile will also source ~/.bashrc.
• You may have to log out and then log in for man ffmpeg to work.
• Don't worry: you can undo any of this as shown in Reverting Changes Made by This Guide.

See ​Ubuntu Wiki: Persistent Environment Variables for more info.

Additional Notes

• See the H.264 Encoding Guide for some encoding examples.
• If you do not see FFmpeg developers in your ffmpeg console output then something went wrong and you're probably using the​fake "ffmpeg" from the repository.
• HTML formatted documentation is available in ~/ffmpeg_build/share/doc/ffmpeg.
• You can keep the ffmpeg_sources directory if you plan on updating later. SeeUpdating FFmpeg below for more details followed by instructions for reverting all changes made by this guide.

Updating FFmpeg

Development of FFmpeg is active and an occasional update can give you new features and bug fixes. First you need to delete (or move) the old files:

rm -rf ~/ffmpeg_build ~/ffmpeg_sources ~/bin/{ffmpeg,ffprobe,ffserver,vsyasm,x264,yasm,ytasm}

Now just follow the guide from the beginning.
