By what I gather from the description, I would say it makes most sense
to have such a "aacslib" for getting the title key, whereas decrypting
the (e)vob with a given title key would make more sense to handle in
FFmpeg, since to decrypt you have to parse the stream, which the demuxer
already does. Not sure how ugly it would get to extend the MPEG demuxer
for that though.
