2014-02-18vp9_vaq.c: Cast result of round() to int to silence warning caused by ↵Tom Finegan
clamp() call. clamp() wants an int, round returns a double, warning! Too bad we can't just use lrint. Change-Id: I9c08289dde742fac0d673df8559a1892edcd1bc7

2014-02-11Modified Aq1 and Aq2Paul Wilkins
Aq 1 only updates segment map on kf and arf and only uses 3 segments. With these settings AQ1 is + for most clips in SSIM but negative in psnr. However, the penalty in PSNR is much less than previously. Old version aq1 average results for std hd -20.899% psnr, -5.809% SSIM New version aq1 for std hd -3.57% psnr, +1.23% SSIM Aq2 Now uses only 2 segments and rd. This mode is still slightly negative for most clips on psnr and SSIM but seems to have a much bigger visual impact on several problem clips than aq mode 1. Old results for std hd: -2.578% psnr, -1.151% SSIM New results for std hd: -1.561% psnr, -0.85% SSIM Change-Id: I94f57f8a73121629ce598fb921aad761c1450e1c

2013-10-17Add missing calls to emms in the adaptive quantization codeGuillaume Martres
Also avoid using floating-point operations when adaptive quantization is disabled. Change-Id: I54936d7afb661df049cdb3ecd246d04ac2a9d8d3
2013-10-16Implement variance-based adaptive quantizationGuillaume Martres
This should be similar to what x264 does with --aq-mode 1. It works well with clips like parkjoy and touhou (http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv). At low bitrates, the segmentation signaling overhead may negate the benefits of this feature. (PGW) Default changed to feature OFF to allow provisional merge.
