Adds parameter height to functions kvz_inter_recon_lcu and
kvz_inter_recon_lcu_bipred and makes them work on non-square sizes.
Fractional reconstruction functions do not handle non-square blocks yet.
- Moves SIZE_* definitions to cu.h.
- Adds constant arrays kvz_part_mode_num_parts, kvz_part_mode_offsets
and kvz_part_mode_sizes for storing the number of PUs, PU offsets and
PU sizes.
- Adds macros PU_GET_X, PU_GET_Y, PU_GET_W and PU_GET_H for getting the
location and size of a PU.
Moves checks for motion vector prediction and merge candidate block
types (inter/intra) from functions kvz_inter_get_mv_cand and
kvz_inter_get_merge_cand to kvz_inter_get_spatial_merge_candidates.
Remove the need to count the coefficients by populating the significant
coefficient group map first and finding the last coefficient from the
last group afterward. The speedup is about 2% on ultrafast.
The previous version of this patch was reverted due to a bug, which
has now been fixed.
This reverts commit 25462124f8.
That commit broke the bitstream. If it's not good enough to push on Friday
night, it's probably not good enough on Monday morning either.
Remove the need to count the coefficients by populating the significant
coefficient group map first and finding the last coefficient from the
last group afterward.
Increases the MV safety margin of OWF from 2 to 3 when deblocking
is used and 4 when both deblocking and FME are used.
Fractional pixel motion estimation can move the vector one more pixel
down causing checksum error. This fixes that error by increasing the
OWF safety margin and changes the interface, so that different margin
can be used when FME or deblocking are not in use.
Replaces repetitive calls to kvz_filter_deblock_luma and
kvz_filter_deblock_chroma with loops in functions
filter_deblock_edge_luma and filter_deblock_edge_chroma.
Marks the following functions static and removes them from filter.h
since they are not used outside the filter module.
- kvz_filter_deblock_luma
- kvz_filter_deblock_chroma
- kvz_filter_deblock_edge_luma
- kvz_filter_deblock_edge_chroma
- kvz_filter_deblock_cu
- Replace parameter depth in kvz_filter_deblock_edge_{luma,chroma} with
length.
- Move checking whether an edge needs to be filtered from functions
kvz_filter_deblock_edge_{luma,chroma} to functions
kvz_filter_deblock_{cu,lcu}.
- Use pixel coordinates instead of 8-pixel block coordinates in
kvz_filter_deblock_cu.
- Add comments.
These changes should make it easier to modify the deblocking filter to
handle SMP and AMP blocks.
The mac version of KVZ_GET_TIME macro has many statements, which
prevented it being used inside a for loop statement. Added brackets
to all versions to prevent this issue arising in the future.
Fixes#115.
Giving a single number as an argument to --deblock option would enable
deblocking and set both beta and tc to that value. This commit changes
a single number argument to be interpreted as a boolean specifying
whether to enable deblocking or not. As a result, "--deblock 0" can be
now used to disable deblocking.
This fixes deblocking being enabled in all presets.
