2011-04-14Merge "Refactor lookahead ring buffer"John Koleszar
2011-04-13Use consistent delimiters.Fritz Koenig
opsnr.stt file was using \t for delimiters on everything except between VPXSSIM and Time. Change-Id: I6284c4e40c05ff642bf4b0170dca062c279a42df
2011-04-13Refactor lookahead ring bufferJohn Koleszar
This patch cleans up the source buffer storage and copy mechanism to allow access through a standard push/pop/peek interface. This approach also avoids an extra copy in the case where the source is not a multiple of 16, fixing issue #102. Change-Id: I05808c39f5743625cb4c7af54cc841b9b10fdbd9

2011-04-04Merge "Use full-pixel MV in mvsadcost calculation"Yunqing Wang
2011-04-01Use full-pixel MV in mvsadcost calculationYunqing Wang
MV sad cost error is only used in full-pixel motion search, which only need full-pixel resolution instead of quarter-pixel resolution. This change reduced mvsadcost table size, and removed unneccessary pamameter passing since this table is constant once it is generated. Change-Id: I9f931e55f6abc3c99011321f1dfb2f3562e6f6b0

2011-03-17Increase static linkage, remove unused functionsJohn Koleszar
A large number of functions were defined with external linkage, even though they were only used from within one file. This patch changes their linkage to static and removes the vp8_ prefix from their names, which should make it more obvious to the reader that the function is contained within the current translation unit. Functions that were not referenced were removed. These symbols were identified by: $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \ | sort | grep '^ *1 ' Change-Id: I59609f58ab65312012c047036ae1e0634f795779
2011-03-11Clean up of vp8_init_config()Paul Wilkins
Clean up vp8_init_config() a bit and remove null pointer case, as this code can't be called any more and is not an adequate trap anyway, as a null pointer would cause exceptions before hitting the test. Change-Id: I937c00167cc039b3aa3f645f29c319d58ae8d3ee
2011-03-11Merge "1 Pass CQ and VBR bug fixes"John Koleszar
2011-03-111 Pass CQ and VBR bug fixesPaul Wilkins
Issue 291 highlighted the fact that CQ mode was not working as expected in 1 pass mode, This commit fixes that specific problem but in so doing I also uncovered an overflow issue in the VBR code for 1 pass and some data values not being correctly initialized. For some clips (particularly short clips), the resulting improvement is dramatic. Change-Id: Ieefd6c6e4776eb8f1b0550dbfdfb72f86b33c960

2011-03-11Merge "Encoder loopfilter running in its own thread"Yunqing Wang
2011-03-11Encoder loopfilter running in its own threadAttila Nagy
In multithreaded mode the loopfilter is running in its own thread (filter level calculation and frame filtering). Filtering is mostly done in parallel with the bitstream packing. Before starting the packing the loopfilter level has to be calculated. Also any needed reference frame copying is done in the filter thread. Currently the encoder will create n+1 threads, where n > 1 is the number of threads specified by application and 1 is the extra filter thread. With n = 1 the encoder runs in single thread mode. There will never be more than n threads running concurrently. Change-Id: I4fb29b559a40275d6d3babb8727245c40fba931b
2011-03-10Removed firstpass motion mapAdrian Grange
The firstpass motion map consists of an 8-bit flag for each MB indicating how strongly the firstpass code believes it should be filtered during the second pass ARNR filtering. For long or large format material the motion map can become extremely large and hamper the operation of the encoding process. This change removes the motion map altogether, leaving the second pass to rely on the magnitude of the motion compensated error to determine the filter weight to use for the MB during ARNR filtering. Tests on the derf set indicate that the effect of this change is neutral, with some small wins and losses. The motion map has therefore been removed based on a cost/benefit evaluation.

2011-02-16Merge "Allocate source buffers to be multiples of 16"Yunqing Wang
2011-02-16Allocate source buffers to be multiples of 16Yunqing Wang
Currently, when the video frame width is not multiples of 16, the source buffer has a stride of non-multiples of 16, which forces an unaligned load in SAD function and hurts the performance. To avoid that, this change allocates source buffers to be multiples of 16. Change-Id: Ib7506e3eb2cea06657d56be5a899f38dfe3eeb39

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.

2011-02-04correct 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

2011-02-03Merge "Improved encoder threading"Yunqing Wang
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
