2016-01-08Modifies inter/intra coding to allow all tx typesDebargha Mukherjee
The nominal tx_type for a given mode is used as a context to encode the actual tx_type for intra. Results: derflr: -0.241% BDRATE hevcmr: -0.366% BDRATE Change-Id: Icfe7b0a58d79bc6497a06e3441779afec6e01e21
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

For testing implemented a fixed pattern and delta, 1 pass, fixed Q, low delay mode. This has not in any way been tuned or optimized. Change-Id: Icf9b57c3bb16cc5c0726d5229009212af36eb6d9
2015-12-151 pass VBR mode bug fix.paulwilkins
(copied from VP9) The one pass VBR mode selects a Q range based on a moving average of recent Q values. This calculation should have been excluding arf overlay frames as these are usually coded at the highest allowed value. Their inclusion skews the average and can cause it to drift upwards even when the clip as a whole is undershooting. As such it can undermine correct adaptation of the allowed Q range especially for easy content. Change-Id: I9e12da84e12917e836b6e53ca4dfe4f150b9efb1

2015-12-14Fix a enc/dec mismatch under CONFIG_MISC_FIXESYaowu Xu
The culprit is on the decode side xd->lossless[i] setup was in wrong location where segment features are not yet decoded. Also on the encoder side, transform mode was not set consistently between when tx_mode is selected and how tx_mode is enforced in tx size selection.
