I removed the sorting from the plist builder, including the two sort
functions, it now consumes 130 fewer lines of code. I sent Vitor the
replacement. The number of lines specific to this method, including the
existing code, is around 75.
Keeping the progressive reducer in is a good idea as the quality factor
needed to maintain a bitrate gets extremely erratic, and it may be
neccessary to cap frame sizes, although I am admittedly a newbie when it
comes to rate control.
