Bandau instaliuoti ffmpeg pagal žemiau pateiktas rekomendacijas, bet cmd 
sako netinka komandos nei admino teisėmis nei paprastai. Na ir kam tokie 
izdevonai? Ne gi neįmanoma padaryti paprasto setup'o? :(

## Installing FFmpeg

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.
