2015-10-16vp10: allow forward updates for keyframe y intra mode probabilities.Ronald S. Bultje
See issue 1040 point 5. Change-Id: I51a70b9eade39efba392a1457bd70a3c515525cb
2015-10-16vp10: merge keyframe/interframe uvintramode/partition probabilities.Ronald S. Bultje
This has various benefits: - simplify implementations because we don't have to switch between multiple probability tables depending on frametype - allows fw subexp and bw adaptivity for partitions/uvmode in keyframes See issue 1040 point 5. Change-Id: Ia566aa2863252d130cee9deedcf123bb2a0d3765
2015-10-16vp10: make segmentation probs use generic probability model.Ronald S. Bultje
Locate them (code-wise) in frame_context, and have them be updated as any other probability using the subexp forward and adaptive bw updates. See issue 1040 point 1. TODOs: - real-world default probabilities - why is counts sometimes NULL in the decoder? Does that mean bw adaptivity updates only work on some frames? (I haven't looked very closely yet, maybe this is a red herring.) Change-Id: I23b57b4e5e7574b75f16eb64823b29c22fbab42e

2015-10-12vp10: remove ref-MV-dependent use of HP.Ronald S. Bultje
This change (in a new config experiment: universal_hp) removes the bitstream parsing dependency of the HP MV bit on the ref MV to be coded. It also cleans up clearing of the HP bit in near/nearestMV, since HP is always on if it's set in the frame header. This admittedly doesn't clean up the crap that could be cleaned up, but that's mostly because I think this needs some careful review; not so much for coding style, but more from hardware people and from the codec team on what we/you want. It would also be nice to get some actual numbers on the real quality impact of this change. If, for example, hardware people come up and tell us they don't actually care anymore, we should probably just this code as-is and do nothing (i.e. discard this patch). See issue 1036.

2015-10-12vp10: remove clamp_mv2() call from vp10_find_best_ref_mvs().Ronald S. Bultje
This actually has no effect whatsoever, since the input MVs themselves are clamped by clamp_mv_ref() already, which is significantly more restrictive in its bounds. Change-Id: I4a3a7b2b121ee422c56428c2a12d930c3813c06e

2015-10-01vp10: reimplement d45/4x4 to match vp8 instead of vp9.Ronald S. Bultje
This is more a proof of concept than anything else. The problem here isn't so much how to code it, but rather where to place the resulting code. All intrapred DSP code lives in vpx_dsp, so do we want the vp10 specific intra pred functions to live there, or in vp10/? See issue 1015. Change-Id: I675f7badcc8e18fd99a9553910ecf3ddf81f0a05
2015-09-25Rename display_{size,width,height} to render_*.Ronald S. Bultje
The name "display_*" (or "d_*") is used for non-compatible information (that is, the cropped frame dimensions in pixels, as opposed to the intended screen rendering surface size). Therefore, continuing to use display_* would be confusing to end users. Instead, rename the field to render_*, so that struct vpx_image can include it.

2015-09-25vp10: split UV int4x4 loopfilter flag in one for each covered edge.Ronald S. Bultje
In practice, this fixes the issue that if you have an odd number of mi_cols, on the full right of the image, the UV int4x4 loopfilter will be skipped over odd cols as well as odd rows (because it holds a single variable for both edges). See issue 1016. Change-Id: Id53b501cbff9323a8239ed4775ae01fe91874b7e
2015-09-25vp10: remove MACROBLOCK.{highbd_,}itxfm_add function pointer.Ronald S. Bultje

2015-09-16vp10: do sub8x8 block reconstruction in full subblocks.Ronald S. Bultje
This means that we don't reconstruct in 4x4 dimensions, but in blocksize dimensions, e.g. 4x8 or 8x4. This may in some cases lead to performance improvements. Also, if we decide to re-introduce scalable coding support, this would fix the fact that you need to re-scale the MV halfway the block in sub8x8 non-4x4 blocks. See issue 1013.

2015-09-16vp10: fix 4:2:2 chroma MVs for 8x4/4x4 blocks.Ronald S. Bultje
In vp9, the bottom MV would be the average of the topright and bottomleft luma MV (instead of the bottomleft/bottomright luma MV). See issue 993. Change-Id: Ic91c0b195950e7b32fc26c84c04788a09321e391
2015-09-16vp10: remove double MV value check.Ronald S. Bultje
This has virtually no effect on coding efficiency, but it is more logical from a theoretical perspective (since it makes no sense to me that you would exclude a MV from a list just because it's sign- inversed value is identical to a value already in a list), and it also makes the code simpler (it removes a duplicate value check in cases where signbias is equal between the two MVs being compared). See issue 662. Change-Id: I23e607c6de150b9f11d1372fb2868b813c322d37
2015-09-16vp10: don't reset contextual skip flag if block has no coefficients.Ronald S. Bultje
The implicitly changed value would be used for contextualizing future skip flags of neighbour blocks (bottom/right), which is certainly not what was intended. The original code stems from vp8, and was useful in cases where coding of the skip flag was disabled. In vp9, the skip flag is always coded. The result of this change is that for bitstream parsing purposes, decoding of the skip flag becomes independent of decoding of block coefficients. See issue 1014.

2015-09-16Add support for color-range.Ronald S. Bultje
In decoder, export (eventually) into vpx_image_t.range field. In encoder, use oxcf->color_range to set it (same way as for color_space). See issue 1059. Change-Id: Ieabbb2a785fa58cc4044bd54eee66f328f3906ce

2015-09-14vp10: fix entropy counts for the hp bit.Ronald S. Bultje
The counts didn't take usehp into account, which means that if the scope of the refmv is too large for the hp bit to be coded, the value (always 1) is still included in the stats. Therefore, the final counts will not reflect the entropy of the coded bits, but rather the entropy of the combination of coded bits and the implied value (which is always 1). Fix that by only including counts if the hp bit is actually coded. See issue 1060. Change-Id: I19a3adda4a8662a05f08a9e58d7e56ff979be11e

2015-09-11Make reset_frame_context an enum.Ronald S. Bultje
In vp9, [0] and [1] had identical meaning, so merge them into a single value. Make it impossible to code RESET_FRAME_CONTEXT_NONE for intra_only frames, since that is a non-sensical combination. See issue 1030. Change-Id: If450c74162d35ca63a9d279beaa53ff9cdd6612b
