i've been trying to keep track of bluray/hddvd support here:

needs updating re: interlaced vc1/h264.

except the drive _is_ the donation, exactly FOR the aacs support.

there is an aacs implementation in java, and a guide how to rip the
movies on linux:
https://help.ubuntu.com/community/RestrictedFormats/BluRayAndHDDVD

this aacs lib could be a nice GSoC project, of course it doesnt have to
be ffmpeg's. it could go in VLC or any group :)

while this lib cannot use AACS to decrypt (because it has no player key
for itself), it should allow users to use keys from other players.

e.g. ffmpeg + aacslib reads from ~/.aacs/keys
it would have a list of known player and disk keys:
