2011-11-04Fix issue 374: eob read incorrectlyTero Rintaluoma
Updated eob changes to check_reset_2nd_coeffs function. Change-Id: Id1b21c91c7f0fd286640b487ffe47867009b717d

2011-11-03Change use of eob in the encoderTero Rintaluoma
Changed 'int eob' to 'char *eob' in BLOCKD so that both encoder and decoder will use eobs[25] array from MACROBLOCKD structure. In future, this will enable use of the decoder side IDCT in the encoder. Change-Id: I6e1c011628cb8864fd4a0b80f0279ce16a5ca978

2011-11-01Changing decoder input partition API to input fragments.Stefan Holmer
Adding support for several partitions within one input fragment. This is necessary to fully support all possible packetization combinations in the VP8 RTP profile. Several partitions can be transmitted in the same packet, and they can only be split by reading the partition lengths from the bitstream. Change-Id: If7d7ea331cc78cb7efd74c4a976b720c9a655463
2011-11-01Add checks in MB quantizer initializationYunqing Wang
In some situations (f.g. error-resilient is turned on), vp8cx_mb _init_quantizer() was called once per macroblock. Added checks to avoid calculations when there is no change. Change-Id: Ie4f0a5ade2202041254990a4e9d5b03bd1ac5aea
2011-10-31Correct SPLITMV clampingJohn Koleszar
Prior to this fix, the clamping state of the last subblock partition dominated, whereas the correct behavior is to clamp if any partition needs clamping. This bug was introduced by v0.9.6-232-g6b25501 See also: [1]: http://code.google.com/p/webm/issues/detail?id=371 [2]: https://bugzilla.mozilla.org/show_bug.cgi?id=696390 Change-Id: I444db492b4c4f05f039c7da6f4216da8207dc138
2011-10-28added code to clear 2nd order block when appropriateYaowu Xu
It is discovered that in rare situations the 2nd order block may produce a few small magnitude coefficients that has no effect on reconstruction. The situations are a combination of low quantizer values (high quality) and low energy in residual signals (content dependent). This commit added code to detect such cases and reset the 2nd order block to all 0. Patch 1 to 4 used code to do all-zero-check on idct result buffer, and tests on derf set showed a consistent gain of .12%-.14% on all metrics.But due to a recent change Ie31d90b, the idct result buffer is not longer populated. So patch 5&6 use an alternative method to detect the situations. Tests on derf set now shows a consistent quality gain of .16%-.20%. As suggested by Jim, Patch 7&8 removed the condition of all first order block not having any coefficient, instead we reset 2nd order coefficients to all 0 if sum of absolute value of the coefficients is small. So it does slightly more than just detecting the oddity as discussed above, but tests on derf set now show a consistent gain of .20%-.23% on all metrics. It is worth noting here that this change does not have any effect on mid/high quantizer range, it only affects the quantizer value 18 or blow. Within this range, the change helps compression by up to 2.5% on clips in the derf set. Change-Id: I718e19cf59a4fc2462cb7070832759beb9f7e7dd

Interleaved vp8_find_near_mvs and vp8_mv_ref_probs. 2.5% to 4% performance improvement for the HD clips used. Change-Id: Id888b667cf5ae2f0e19da18743140f055ff7de8d
2011-10-26Reduce partial frame copy in encoder's pick_filter_level_fastAttila Nagy
The partial frame copy function used to copy an extra 8 lines above and below. The partial frame filtering can only modify 3 pixel rows above the partial frame. Reduce copy to bare minimum needed, which is 4 lines, so that partial filtering on copied frame is possible. Define the "magic" fraction number for partial filtering in loopfilter.h .

2011-10-24Removed read_mv_refScott LaVarnway
Decode the mv mode with if-then-elses instead of traversing the vp8_mv_ref_tree data structure. This will make it easier to interleave vp8_find_near_mvs and vp8_mv_ref_probs. Change-Id: I1e798d6ec40fcaeeff06ccc82f81201978d12f74

2011-10-19Merge "Remove usage of predict buffer for decode"Scott LaVarnway
2011-10-18Remove usage of predict buffer for decodeScott LaVarnway
Instead of using the predict buffer, the decoder now writes the predictor into the recon buffer. For blocks with eob=0, unnecessary idcts can be eliminated. This gave a performance boost of ~1.8% for the HD clips used. Tero: Added needed changes to ARM side and scheduled some assembly code to prevent interlocks. Patch Set 6: Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3) into this commit because of similarities in the idct functions. Patch Set 7: EC bug fix.

2011-10-14Fix: vp8cx_pack_tokens_into_partitions_armv5 crashAttila Nagy
It was crashing when number of partitions was bigger than the number of MB rows (ex. 128x96 with 8 partitions). Start point was not checked against mb_rows, plus extra "empty" partitions were not written out. Change-Id: I9c2f013b9ec022354b658fab4ef799ff8b1de93d

2011-10-11Added rate-targeted temporal scalabilityAdrian Grange
Added the ability to create rate-targeted, temporally scalable, VP8 compatible bitstreams. The application vp8_scalable_patterns.c demonstrates how to use this capability. Users can create output bitstreams containing upto 5 temporally separable streams encoded as a single VP8 bitstream. (previously abandoned as: I92d1483e887adb274d07ce9e567e4d0314881b0a) Change-Id: I156250a3fe930be57c069d508c41b6a7a4ea8d6a

buffer_level in VP8_COMP and starting_buffer_level, optimal_buffer_level and maximum_buffer_size in VP8_CONFIG changed from int to int64_t to avoid potential crash issues for larger target bit rates. Change-Id: I0d5ab6c8a44c2fef51f30cd8df4bb4b739c5df26
