I have.  I actually helped out a bit with the VLC Quicktime and OpenGL
code on the Mac.

The main problem is fitting these APIs into a flexible framework and
still have them work with a decent level of efficiency and stability.
For example, letting DirectShow do everything from open the file to
display the pixels on screen can be quite fast, but there is no way to
use that pipeline inside of GEM - you couldn't insert a pix_ object or
have the pixels as a texture in OpenGL.  Once you get outside of the
pretty narrowly defined areas the API engineers think you need things
tend to fall apart fairly quickly.
