pub(crate) const EMPTY_S: f64 = 3.0;Expand description
Seconds of such frames after which a constant-rate cleanup through x264 ends: x264 keeps its
quantizer on a screen that does not change, and at 0.1 Mbit/s refines one in frames as far
as 2.4 s apart. A session that holds no quantizer and measures nothing ends the same way
once its frames at its coarsest have kept the size of the one before as long
(SAME_FRAME_SHARE).
