"output to stdout" has been a wanted feature for a very long time now.
It has never been implemented largely because, for an even longer time,
some of the text printed during playback has been sent via stdout
(rather than stderr) - and it would thus wind up going into the middle
of the output file and corrupting the data.

There have been efforts, over time, to clean up the code so that text is
not printed via stdout in that way. It's possible that the goal may even
have been accomplished by now. If so, however, it hasn't gotten much
attention, and the necessary follow-up work to let MPlayer/MEncoder
output to stdout has in any case not been done.
