 There is also a script "make_src_tree.sh" that automates most of the steps
 above for you.  It is currently only tested on linux.
 
 NOTE: Under Windows it is recommended to use Chromium's MinGW/MSYS environment
 or 7-Zip to extract the archives.  We've experienced issues when using WinRAR.
 
 Since FFmpeg is sandboxed inside the render process, we're only interested in
 building the absolute minimum.
