There is experimental software (unrelated to MPlayer) to do this, but
the quality is rather poor. In principle this process will never give
very good results. I would either stick with 12 fps or use a better

If you do want to try adding filters to MPlayer for this purpose, they
must be C, not C++. MPlayer does not include C++ code except a few
wrappers for C++ libraries that will be removed as soon as possible.
