3 1. Type `./configure` to create the configuration. A list of configure
4 options is printed by running `configure --help`.
6 `configure` can be launched from a directory different from the FFmpeg
7 sources to build the objects out of tree. To do this, use an absolute
8 path when launching `configure`, e.g. `/ffmpegdir/ffmpeg/configure`.
10 2. Then type `make` to build FFmpeg. GNU Make 3.81 or later is required.
12 3. Type `make install` to install all binaries and libraries you built.
17 - Non system dependencies (e.g. libx264, libvpx) are disabled by default.
19 NOTICE for Package Maintainers
20 ------------------------------
22 - It is recommended to build FFmpeg twice, first with minimal external dependencies so
23 that 3rd party packages, which depend on FFmpegs libavutil/libavfilter/libavcodec/libavformat
24 can then be built. And last build FFmpeg with full dependancies (which may in turn depend on
25 some of these 3rd party packages). This avoids circular dependencies during build.
