2011-02-14mem leak fix for cpi->tplistJames Berry
checks added to make sure that cpi->tplist is freed correctly in vp8_dealloc_compressor_data and vp8_alloc_compressor_data. Change-Id: I66149dbbd25c958800ad94f4379d723191d9680d

2011-02-11Add improved_mv_pred flag in real-time modeYunqing Wang
As mentioned in check-in "Improve motion search in real-time mode", MV prediction calculation causes speed loss for speed 7 and above. This change added a flag to turn off this calculation for speed>6 in real-time mode. Change-Id: I9f4ae5a8bf449222d1784b54e7d315fc8347b2d1

2011-02-10Improve motion search in real-time modeYunqing Wang
Applied better MV prediction in real-time mode, which improves the encoding quality. Used quarter-pixel search instead of iterative sub-pixel search for speed >=5 to improve encoding performance. Tests on the test set showed: 1. For speed=-5, quality improvement: 1.7% on AvgPSNR and 2.1% on SSIM, performance improvement: 3.6% (This counts in the performance lose caused by MV prediction calculation in "Improve MV prediction in vp8_pick_inter_mode() for speed>3"). 2. For speed=-8, quality improvement: 2.1% on AvgPSNR and 2.5% on SSIM. but, 6.9% performance decrease because of MV prediction calculation. This should be improved later.

2011-02-09correct cost for implicit bit in mvsJohn Koleszar
Use 0xFFF0 vice 240 (0xF0) for determining whether the sometimes implicit bit 3 will be transmitted. This is consistent with the decoder and encode_mvcomponent(). Change-Id: Ic1304d0ab56844bed8236edd1c5243a6767fc6b1

2011-02-08clarify *_offsets.asm differencesJohann
it's difficult to mux the *_offsets.c files because of header conflicts. make three instead, name them consistently and partititon the contents to allow building them as required. Change-Id: I8f9768c09279f934f44b6c5b0ec363f7943bb796

2011-02-04correct quantizer initializationJohn Koleszar
The encoder was not correctly catching transitions in the quantizer deltas. If a delta_q was set, then the quantizer would be reinitialized on every frame, but if they transitioned to 0, the quantizer would not be reinitialized, leading to a encode-decode mismatch. This bug was triggered by commit 999e155, which sets a Y2 delta Q for very low base Q levels. Change-Id: Ia6733464a55ee4ff2edbb82c0873980d345446f5

2011-02-02Delay auto key frame insertion in realtime configurationAttila Nagy
Whe auto keyframe insertion is enabled and conditions are right (scene change) the encoder can decide to insert a key frame and does a re-encoding. This can introduce extra latency. In RT mode we do not do the re-encoding of the current frame but force the next frame to key frame. Change-Id: I15c175fa845ac4c1a1f18bea3676e154669522a7

Restructured function in order to eliminate the prediction modes save/restore. Code cleanup also. Change-Id: I816e3b910de64d0f0f0ddc2398805c63263191e8
2011-02-01Improved encoder threadingAttila Nagy
Reduce the number of sync points by letting each thread continue imediatly with a new MB row. Better multicore scaling, improves performance by 5-20% on ARM multicore. Change-Id: Ic97e4d1c4886a842c85dd3539a93cb217188ed1b
2011-01-31Removed prediction_error accumulationScott LaVarnway
from vp8cx_encode_intra_macro_block. prediction_error is used when deciding if a frame should be a keyframe. After reviewing this with Yaowu, it was pointed out that vp8cx_encode_intra_macro_block is only called for keyframes, so the accumulation is unnecessary. Change-Id: Id79dc81b80d4f5d124f3a0dba1b923887e2e1ec8

2011-01-31Possible bug in vp8cx_encode_intra_macro_blockScott LaVarnway
vp8_pick_intra4x4mby_modes uses the passed in distortion for an early breakout. The best distortion was never saved and the distortion for TM_PRED was always used. Change-Id: Idbaf73027408a4bba26601713725191a5d7b325e

2011-01-28change the threshold of DC check for encode breakoutYaowu Xu
Previously, the DC check is to make sure there is no code-able DC shift for quantizer Q0, which has been verified rather conservative. This commit changes the criteria to have two components, DC and AC, to address the conservativeness. First, it checks if all AC energy is enough to contribute a single non-zero quantized AC coefficient. Second, for DC, the decision to skip further considers two possible scenarios: 1. There is no code-able 2nd order DC coefficient at all; 2 The residue is relatively flat, but the uniform DC change is very small, i.e. less than 1/2 gray level per pixel. Comparing to previous criteria, the new criteria is about 10% to 15% faster in encoding time with a very small quality loss. (threshold ~1000 and quality range 33db-45db) It should be noted that this commit enables "automatic" static threshold for encodebreakout if a non-zero small value is passed in to encoder.

2011-01-28Changed condition for using RD in Intra ModeAdrian Grange
The condition for using RD when selecting the intra coding mode for a MB is that the RD flag is set AND we're not in real-time mode. Previously the code used RD if either the RD flag was set OR we were not using real-time mode. Change-Id: Ic711151298468a3f99babad39ba8375f66d55a08
2011-01-28Inconsistent distortion metric in vp8_rd_pick_intra_mbuv_modePaul Wilkins
This function was using a variance metric compared to and SSE metric in other places (eg. vp8_rd_inter_uv) Change-Id: I9109fcc5a13bca9db1d7ead500fe14999ab233eb
2011-01-28Adds "armvX-none-rvct" targetsTero Rintaluoma
Adds following targets to configure script to support RVCT compilation without operating system support (for Profiler or bare metal images). - armv5te-none-rvct - armv6-none-rvct - armv7-none-rvct To strip OS specific parts from the code "os_support"-config was added to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS specific parts such as OS specific includes and function calls for timers and threads etc. This was done to enable RVCT compilation for profiling purposes or running the image on bare metal target with Lauterbach. Removed separate AREA directives for READONLY data in armv6 and neon assembly files to fix the RVCT compilation. Otherwise "ldr <reg>, =label" syntax would have been needed to prevent linker errors. This syntax is not supported by older gnu assemblers. Change-Id: I14f4c68529e8c27397502fbc3010a54e505ddb43
