#Installing FFmpeg:
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.
Then type make to build FFmpeg. GNU Make 3.81 or later is required.
Type make install to install all binaries and libraries you built.
