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

mkdir -p ~/ffmpeg_sources ~/bin

Compilation & Installation This guide assumes that you want to install some of the most common third-party libraries. Each section provides you with the commands needed to install that library.

For each section, copy-paste the entire code-block into your shell.

If you do not require certain features, you may skip the relevant section (if it is not required) and then remove the appropriate ./configure option in FFmpeg. For example, if libvpx is not needed, skip that section and then remove --enable-libvpx from the Install FFmpeg section.

Tip: To significantly speed up the compilation process on systems with multiple cores, you can use the -j option with each make command, such as make -j4.

NASM An assembler used by some libraries.

If your repository provides nasm version ¡Ý2.13 then you can install that instead of compiling:

sudo apt-get install nasm Otherwise you can compile:

cd ~/ffmpeg_sources &&

make install libaom AV1 video encoder/decoder:

Warning: libaom does not yet appear to have a stable API, so compilation of libavcodec/libaomenc.c may occasionally fail. Just wait a day or two for us to catch up with these annoying changes, re-download ffmpeg-snapshot.tar.bz2, and try again. Or skip libaom altogether.
