Read my recent vf proposals. IMO we much switch to get/release buffer
rather than the g1-style system; otherwise G2 will suck and won't be
able to do any DR with new multi-reference-frame codecs or temporal
filters.

Agree.

IMO fix the external lib dependencies (i.e. remove them :).

IMO this is not a con. :)
