const SAME_FRAME_SHARE: f64 = 0.125;Expand description
The share of the frame before it within which a frame of a still screen codes nothing new, and the quality index from which its rate control sits at its coarsest: at 0.1 Mbit/s at 1080p libvpx’s VP9 frames are 266 bytes each at index 51, or 220-221 at 46-47, and x265’s 224 at 50-51, its strict constant rate padding them with filler, while the picture stays level, so never small against the 208-byte budget. From 1 Mbit/s their rate controls code a still screen at 36 and finer, x265’s padded frames again of one size while it refines.
