Does this really quality as example? It's way too complex and seems to
be about a specific use case in place of ffmpeg.c, rather than
demonstrating API use in an educational way (what code examples are
supposed to do).

If someone wants to merge this, at least add it as top level program,
and not under the examples directory.
