2011-05-03Merge "Modify HEX search"Yunqing Wang
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.

2011-05-03change to use fast ssim code for internal ssim calculationsYaowu Xu
The commit also removed the slow ssim calculation that uses a 7x7 kernel, and revised the comments to better describe how sample ssim values are computed and averaged Change-Id: I1d874073cddca00f3c997f4b9a9a3db0aa212276

2011-04-27Use insertion sort instead of quick sortYunqing Wang
Insertion sort performs better for sorting small arrays. In real- time encoding (speed=-5), test on test set showed 1.7% performance gain with 0% PSNR change in average. Change-Id: Ie02eaa6fed662866a937299194c590d41b25bc3d

2011-04-27Speed up VP8DX_BOOL_DECODER_FILLJohn Koleszar
The end-of-buffer check is hoisted out of the inner loop. Gives about 0.5% improvement on x86_64. Change-Id: I8e3ed08af7d33468c5c749af36c2dfa19677f971
2011-04-27Update VP8DX_BOOL_DECODER_FILL to better detect EOSJohn Koleszar
Allow more reliable detection of truncated bitstreams by being more precise with the count of "virtual" bits in the value buffer. Specifically, the VP8_LOTS_OF_BITS value is accumulated into count, rather than being assigned, which was losing the prior value, increasing the required tolerance when testing for the error condition.

2011-04-26Refactor calc_iframe_target_sizeJohn Koleszar
Combine calc_iframe_target_size, previously only used for forced keyframes, with calc_auto_iframe_target_size, which handled most keyframes. Change-Id: I227051361cf46727caa5cd2b155752d2c9789364
2011-04-26Move pick_frame_size() to ratectrl.cJohn Koleszar
This is a first step in cleaning up the redundancies between vp8_calc_{auto_,}iframe_target_size. The pick_frame_size() function is moved to ratectrl.c, and made to be the primary interface. This means that the various calc_*_target_size functions can be made private. Change-Id: I66a9a62a5f9c23c818015e03f92f3757bf3bb5c8

2011-04-25Limit size of initial keyframe in one-pass.John Koleszar
Rather than using a default size of 1/2 or 3/2 seconds for the first frame, use a fraction of the initial buffer level to give the application some control. This will likely undergo further refinement as size limits on key frames are currently under discussion on codec-devel@, but this gives much better behavior for small buffer sizes as a starting point. Change-Id: Ieba55b86517b81e51e6f0a9fe27aabba295acab0
2011-04-25Add rc_max_intra_bitrate_pct controlJohn Koleszar
Adds a control to limit the maximum size of a keyframe, as a function of the per-frame bitrate.

2011-04-25bug fix possible keyframe context divide by zeroJames Berry
vp8_adjust_key_frame_context() divides by estimate_keyframe_frequency() which can return 0 in the case where --kf-max-dist=0. Change-Id: Idfc59653478a0073187cd2aa420e98a321103daa

2011-04-22Fix overflow in temporal_filter_apply_sse2().Ronald S. Bultje
The accumulator array is an integer array, so use paddd instead of paddw to add values to it. Fixes overflows when using large --arnr-maxframes (>8) values. Change-Id: Iad83794caa02400a65f3ab5760f2517e082d66ae
2011-04-21Merge "Remove unused kf rate variables"John Koleszar
2011-04-21Corrected format specifiers in debug print statementsAdrian Grange
The arguments to these fprintfs are int not long int so the format specifier should be "%d" and not "%ld". This was writing garbage in the linux build. Change-Id: I3d2aa8a448d52e6dc08858d825bf394929b47cf3
2011-04-21keep values in registers during quantizationJohann
add an sse4 quantizer so we can use pinsrw/pextrw and keep values in xmm registers instead of proxying through the stack. and as long as we're bumping up, use some ssse3 instructions in the EOB detection (see ssse3 fast quantizer) pick up about a percent on 32bit and about two on 64bit.

2011-04-21Removed unnecessary frame type checksScott LaVarnway
ref_frame is set to INTRA_FRAME for keyframes. The B_PRED mode is only used in intra frames. Change-Id: I9bac8bec7c736300d47994f3cb570329edf11ec0
2011-04-21Removed dc_diff from MB_MODE_INFOScott LaVarnway
The dc_diff flag is used to skip loopfiltering. Instead of setting this flag in the decoder/encoder, we now check for this condition in the loopfilter. Change-Id: Ie2b9cdf9e0f4e8b932bbd36e0878c05bffd28931

Code cleanup. The build inter predictor functions are redundantly checking the mode_info_context for either INTRA_FRAME or SPLITMV. Change-Id: I4d58c3a5192a4c2cec5c24ab1caf608bf13aebfb
2011-04-19Remove unused kf rate variablesJohn Koleszar
Remove tot_key_frame_bits and prior_key_frame_size[] as they were tracked but never used. Remove intra_frame_target, as it was only used to initialize prior_key_frame_size. Refactor vp8_adjust_key_frame_context() some to remove unnecessary calculations. Change-Id: Icbc2c83d2b90e184be03e6f9679e678f3a4bce8f
2011-04-19modify SAVE_XMM for potential 64bit useJohann
the win64 abi requires saving and restoring xmm6:xmm15. currently SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow specifying the highest register used and if the stack is unaligned. Change-Id: Ica5699622ffe3346d3a486f48eef0206c51cf867
