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. Change-Id: Id39b19eace37574dc429f25aae810c203709629b
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

2011-05-12Using int_mv instead of MVScott LaVarnway
The compiler produces better assembly when using int_mv for assignments. The compiler shifts and ors the two 16bit values when assigning MV. Change-Id: I52ce4bc2bfbfaf3f1151204b2f21e1e0654f960f

2011-05-12Modification and issue fix in full-pixel refining searchYunqing Wang
Further modification and wrong implementation fix which caused refining_search and refining_searchx4 result mismatching. Change-Id: I80cb3a44bf5824413fd50c972e383eebb75f9b6f
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

2011-05-10remove a variable no longer in useYaowu Xu
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

global values were being referenced, but the GOT was not being set up. as the GOT is only required for PIC, this issue wasn't caught in the default configuration. Change-Id: I8006e53776139362a76f2c80cf9d0f8458602b2f http://code.google.com/p/webm/issues/detail?id=328
2011-05-10Merge "Use diamond search to replace full search in full-pixel refining search"Yunqing Wang
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 a bug related to gf_active_flags in multi-threaded encoderYaowu Xu
Paul pointed out that the pointer to the gf_active_flags is not being properly incremented in multithreaded encoder. This commit fixes the issue by making sure the gf_active_ptr points to the starting of next group of mb rows. Change-Id: I3246e657d23beabb614dfb880733a68a5fd7e34c

2011-05-06Don't override active_worst_quality in 2 passJohn Koleszar
Commit db5057c introduced a bug in that the active_worst_quality selected by the 2 pass rate controller was being overridden for key frames, causing a severe quality loss. Change-Id: I4865a6fbe3e94e9b4fb9271c7dd68b455d7b371d

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.

2011-05-03Modify HEX searchYunqing Wang
Changed 8-neighbor searching to 4-neighour searching, and continued searching until the center point is the best match. Test on test set showed 1.3% encoding speed improvement as well as 0.1% PSNR and SSIM improvement at speed=-5 (rt mode). Will continue to improve it.
