Because it's more compatible without and works well enough
in a lot of cases.

vaapi is not part of MPlayer.

There is no problem so far.
Video filters do not work on compressed streams.
If there is a problem, then it might be that the
vaapi vo does not support ASS subtitles.
However since vaapi is not part of MPlayer, this is
the wrong place to get help with it (unless you
want to work on getting it into MPlayer, then
you're welcome to discuss that on the -dev-eng list).
