Not sure how this could possibly be considered off-topic for
ffmpeg-devel. :) I'm glad to see you're still around.

Can you briefly enumerate the discrete tasks that you think need to be
done before the decoder is complete? Also for the encoder?

>From a testing perspective, is Dirac designed to be bit exact? And I
suppose it's way too much to hope that the BBC actually has a reference
suite available. I mean, it's not like they have any library of visual
test material for which they own the copyright. :)
