2011-05-19Using partition_info instead of blockd info for splitmvScott LaVarnway
The partition_info struct contains info just for SPLITMV, so it should be used instead of BLOCKD. Eventually, I want to reduce the size of B_MODE_INFO struct found in BLOCKD, so this is the first step toward that goal. Also, since SPLITMV is not supported in vp8_pick_inter_mode(), the unnecessary mem copies and checks were removed. For rt encodes, this gave a slight performance improvement.

2011-05-19Adding error-concealment to the decoder.Stefan Holmer
The error-concealer is plugged in after any motion vectors have been decoded. It tries to estimate any missing motion vectors from the motion vectors of the previous frame. Intra blocks with missing residual are replaced with inter blocks with estimated motion vectors. This feature was developed in a separate sandbox (sandbox/holmer/error-concealment).

2011-05-13Restructure of activity masking code.Paul Wilkins
This commit restructures the mb activity masking code to better facilitate experimentation using different metrics etc. and also allows for adjustment of the zero bin either for encode only or both the encode and mode selection stages It also uses information from the current frame rather than the previous frame and the default strength has been reduced.

2011-05-12Improve framerate adaptationJohn Koleszar
This patch improves the accuracy of frame rate estimation by using a larger, 1 second window. It also more quickly adapts to step changes in the input frame rate (ie 30fps to 15fps) Change-Id: I39e48a8f5ac880b4c4b2ebd81049259b81a0218e

2011-05-11adjusting rd constant slightly by ~10%Yaowu Xu
This is to reflect the RD improvement in the encoder. The change has a small positive impact on quality (0.25% by VPXSSIM and 0.05% by PSNR) Change-Id: Ic66ffc19b10870645088c0624c85556f009fd210

The variable is introduced in commit 2e53e9e53 to make more use of trellis quantization, but this is no longer necessary after RDMULT was made adaptive in a number of later commits. Change-Id: I7420522ec7723f38cf77033466c25afb405d52ae

2011-05-09Use diamond search to replace full search in full-pixel refining searchYunqing Wang
In NEWMV mode, currently, full search is used as the refining search after n-step search. By replacing it with an iterative diamond search of radius 1 largely reduced the computation complexity, but still maintained the same encoding quality since the refining search is done for every macroblock instead of only a small precentage of macroblocks while using full search. Tests on the test set showed a 3.4% encoding speed increase with none psnr & ssim loss. Change-Id: Ife907d7eb9544d15c34f17dc6e4cfd97cb743d41

2011-05-06Fix semaphore emulation on WindowsAron Rosenberg
The existing emulation of posix semaphores on Windows uses SetEvent() and WaitForSingleObject(), which implements a binary semaphore, not a counting semaphore as implemented by posix. This causes deadlock when used with the expected posix semantics. Instead, this patch uses the CreateSemaphore() and ReleaseSemaphore() calls (introduced in Windows 2000) which have the expected behavior. This patch also reverts commit eb16f00, which split a semaphore that was being used with counting semantics into two binary semaphores. That commit is unnecessary with corrected emulation.
