Yaowu Xu	ea0e4f1743	fixed a number of compiling issues ... the commit fixed a number of compiling issues when some epxeriments are turned on at the same time. Change-Id: Idb15b215e2d2a7d25f2707f99ef55a34e7301ce7	2012-05-25 10:55:47 -07:00
Yaowu Xu	e9818bb697	changed the way that default probs for 8x8 is set. ... The commit changed how baseline 8x8 coefficient probabilities are initialized, to be consistent with the initialization of baseline 4x4 coefficient probabilities. The commit does not have any effect on compression. Change-Id: Ifb3902b5dc0b0c2e6dc3aa5d4a6589d528e58355	2012-05-23 10:09:41 -07:00
Deb Mukherjee	813c6c3925	Expanding the coefficient encoding contexts ... This patch expands the set of prev contexts used for video coding from 3 to 4. There is a small improvement of the order of 0.08% for derf and 0.15% on the HD set. The tests were rerun after the various merges last week. There are two columns in each test - the first are the results with the mbskip change, and the second with expanded contexts added on top of that.

Scott LaVarnway	19987dcbfa	Faster vp8_default_coef_probs ... Copies from a generated table instead of building the default coeff probabilities during runtime. Change-Id: I4d9551ea3a2d7d4a4f7ce9eda006495221a8de50	2011-08-16 16:21:21 -04:00
