We have this page:
We could extend the page, probably rename it, add more comments about
using FFmpeg from C++ and link it from the README (which we should
rename DONTREADME so people would actually read it).
As it is the patch is half baked, because:
1. it is not written anywhere that examples can be directly converted
to C++ code
2. the preprocessor hack is only adopted in muxing.c, ignoring all the
other C examples.
