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.
