That's very new, so there's no doc of any kind, although it's simple to
use. The main idea is that I keep a histogram (with leak) of the number
of times that packets arrive with different delays. Then if too many
packets arrive late, I "interpolate a frame" (increase the delay), while
if all packets arrive early, I "drop a frame" (decrease the delay). The
whole thing is quite simple.
