Installing FFmpeg

0. If you like to include source plugins, merge them before configure for example run tools/merge-all-source-plugins

1. Type ./configure to create the configuration. A list of configure options is printed by running configure --help.

   `configure` can be launched from a directory different from the FFmpeg
   

   sources to build the objects out of tree. To do this, use an absolute path when launching configure, e.g. /ffmpegdir/ffmpeg/configure.
2. Then type make to build FFmpeg. GNU Make 3.81 or later is required.
3. Type make install to install all binaries and libraries you built.

NOTICE

• Non system dependencies (e.g. libx264, libvpx) are disabled by default.

NOTICE for Package Maintainers

• It is recommended to build FFmpeg twice, first with minimal external dependencies so that 3rd party packages, which depend on FFmpegs libavutil/libavfilter/libavcodec/libavformat can then be built. And last build FFmpeg with full dependencies (which may in turn depend on some of these 3rd party packages). This avoids circular dependencies during build.
