const PLATEAU_TRIGGERS: u32 = 4;Expand description
Trigger periods between two measurements of a picture a constant-rate cleanup is refining
(FrameEncoder::last_psnr), the gain in dB under which one finds the picture level with
the one before, and the level measurements in a row after which the rate control is done
with it. A rate control that has a whole screen of dense text to refine at 2 Mbit/s at
1080p gains 0.2 dB a second at first, coding a few blocks of it a frame, and one that is
done with a screen under 0.06.
