2016-01-13Fix encoder crashes and enc/dec mismatchesYaowu Xu
This commit adds the logic for segmentation map initialization and disable temporal update of segmentation map when error-resilient mode is on. It fixes the enc/dec mistmates (release build) and assertions(debug) when both aq-mode and error-resilient are on. Change-Id: Id2155e8b28962cf1f64494f4df0c8d79499b6890

2016-01-12VP9: Eliminate unnecessary nearest/near searchesScott LaVarnway
Prior to this patch, read_inter_block_mode_info() would find the nearmv and nearestmv for all modes. Now it does not search for ZEROMV modes and breaks out early for NEARMV and NEWMV modes. Change-Id: Ifa7b1eaf58bb03b9c7792ea5012fef477527d0fd

2016-01-05Assert no mv clamping for scaled referencesYaowu Xu
Under --enable-better-hw-compabibility, this commit adds the asserts that no mv clamping is applied for scaled references, so when built with this configure option, decoder will assert if an input bitstream triggger mv clamping for scaled reference frames.

2016-01-04Assert no 8x4/4x8 partition for scaled referencesYaowu Xu
This commit adds a new configure option: --enable-better-hw-compatibility The purpose of the configure option is to provide information on known hardware decoder implementation bugs, so encoder implementers may choose to implement their encoders in a way to avoid triggering these decoder bugs. The WebM team were made aware of that a number of hardware decoders have trouble in handling the combination of scaled frame reference frame and 8x4 or 4x8 partitions. This commit added asserts to vp9 decoder, so when built with above configure option, the decoder can assert if an input bitstream triggers such decoder bug.

2016-01-04vp10: only assume ONLY_4X4 if segmentation is disabled.Ronald S. Bultje
Otherwise, per-segment lossless might mean that some segments are not lossless and they could still want to use another mode. The per-block tx points remain uncoded on blocks where (per the segment id) the Q value implies lossless. Change-Id: If210206ab1fe3dd11976797370c77f961f13dfa0

2015-12-22aq-mode=3: Don't reset segment if block is determined to be skin.Marco
For coding block sizes <=16X16, if the block is determined to be skin, then always allow for that block to be candidate for refresh. So if that block happens to be on the boost segment(s), segment won't get reset to 0 and delta-q will be applied. PSNR/SSIM metrics neutral (little/no change) on RTC clips. Speed increase small/negligible (< 1%). Some visual improvement on faces in a few RTC clips. Change-Id: I6bf0fce6f39d820b491ce05d7c017ad168fce7d6

2015-12-18Fix for issue 1114 compile errorPeter de Rivaz
In 32-bit build with --enable-shared, there is a lot of register pressure and register src_strideq is reused. The code needs to use the stack based version of src_stride, but this doesn't compile when used in an lea instruction. This patch also fixes a related segmentation fault caused by the implementation using src_strideq even though it has been reused. This patch also fixes the HBD subpel variance tests that fail when compiled without disable-optimizations. These failures were caused by local variables in the assembler routines colliding with the caller's stack frame. Change-Id: Ice9d4dafdcbdc6038ad5ee7c1c09a8f06deca362
