a video filter layer could be fairly seperate, vhook too doesnt touch
that much of ffmpeg

well i belive bobby and kostya are the 2 most qualified students based on
the qualification tasks which where submitted so far, that of course is 
just my feeling based on what i saw and as with all "tests" that can be
flawed. But i do think that bobby should be accepted as student for soc
for which application that is something i dont know, if i had the choice
between a working well written dirac decoder and a working well written
filter system then i certainly would choose the filter system but a
working dirac decoder/encoder is better then a failed attempt to implement
a filter system and a dirac decoder is just implementing whats in a 
specification while the filter system could turn out to be very tricky
that is the combination of direct rendering, slices and frame order
inserting and removing of frames and arbitrary filter graphs could turn
out to be fairly complex ...

i think that bobby should comment on what he thinks would be a better
task for him (that is what he would prefer working on and if he thinks
he can actually design and implement a system supperior to libmpcodecs
that is without any filters ...)
