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
