Do you know if the 1-second keyframe interval was also for reasons of
compute time? (It allows each GOP to be encoded in parallel). It
unfortunately seems a bit short for many streaming applications, and
also prevents rate control from being tested.

At the moment, I run all codecs with rate control on in their constant
quality mode. Perhaps this is not the right thing to do.
