ffmpeg has "installed" headers and headers that are just in the ffmpeg
source tree. since mplayer ships its own copy of ffmpeg, it can include
these private headers in addition to the jheaders that are supposed to
be installed in the package.
yes, mplayer upstream is not supposed to use these headers, but they do
it anyways. this has historic reasons, and I have the impression they
slowly try to get away from this as ffmpeg matures more and more.
