const SETTLE_RECENT: usize = 2;Expand description
Of two anchors, the one marked predicts from the frame every consumer was sent (settle) only
where that is one of the SETTLE_RECENT newest recent frames, which the buffer keeps beside two
anchors on every device (nvenc::anchor_count). Further back the anchor costs the moving
picture: NVENC’s HEVC on a 1080p page scrolling at 8 Mbit/s, every consumer’s acknowledgement
late, averaged 49.3 dB from two frames back, 49.0 from three, 38.5 from four and 27.4 from the
other anchor a period back (the frame sent to all of them past the recent ones), against 49.7.
The anchor predicts from the frame before it then, and a consumer that loses frames is predicted
past from the pinned anchor on its own report.
