This depends on which hardware decoder you want to use,
at least the following APIs are "supported" (please
understand that in this case, this does not mean you
can use them without any additional effort, it just
means that some code necessary to use hardware
decoding is in place, you typically have to add code
inside your application):
xvmc, vdpau, va-api, dxva
OpenElec has added xvba code to their local copy of
Addionally, stagefright probably allows you to use
hardware decoding in a more straight-forward manner.

Both MPlayer and vlc use (different) hardware
decoders supported by libavcodec.
