Changes reference index list creation so that the negative references
are added to L1 in addition to L0 when biprediction is enabled and no
reordering of pictures is done. Biprediction can now be used with the
low-delay GOP structure.
Changes the crypto module to use unsigned char instead of byte. The byte
typedef is no longer included in the global namespace in crypto++ 6.0.0.
See https://github.com/weidai11/cryptopp/issues/442.
Fixes#184.
Checks the cost of flushing all coefficients of an inter block to zero.
This is much faster than doing full RDOQ but can still reduce bitrate
significantly. Encoding speed is increased since fewer coefficient bits
have to be coded with CABAC.
Moves duplicate code for writing the MVD of a single motion vector from
kvz_get_mvd_coding_cost_cabac and encoder_inter_prediction_unit to a new
function.
SMP/AMP search is performed using a lower work tree level than the
normal inter search so the prediction info must be copied up if an
SMP/AMP mode is chosen. Previously pixels and coefficient were copied as
well. Changed to only copy prediction info.
DST function was returned for inter luma transform blocks of size 4x4
even though they must use DCT. Fixed by checking the prediction mode of
the block in addition to whether it is chroma or luma.
When 4x4 intra blocks are enabled and inter search is limited to 16x16
and larger blocks, it is possible that inter search is accidentally done
for 4x4 blocks. Fixed by checking that block size is at least 8x8 before
doing inter search.
Overrides the linkers used for kvazaar, libkvazaar.la and kvazaar_tests.
When crypto++ is enabled, the C++ linker is used and when it is
disabled, the C linker is used.
This removes the need to explicitly specify -lstdc++ in configure when
crypto++ is used and fixes the build with crypto++ when libstd++ is not
installed.
GCC requires -lpthread in order to link the shared library against the
pthread library. By default the AX_PTHREAD macro only outputs the
-pthread flag for GCC. Changed to force AX_PTHREAD to check -lpthread.
- Fixes two errors in calculating the POC for the reference frame for
temporal candidate MV scaling.
- Fixes using the MV for the wrong direction when the temporal MV
predictor block uses bi-prediction.
Fixes#160.
Changes handling of intra pictures for --gop=8 so that every picture
with POC divisible by the intra period is intra. The first picture is
IDR and the rest of the intra pictures are CRA. POC is not reset at CRA
pictures. The leading pictures that follow the CRA picture are changed
to RASL so they are allowed to refer to pictures before the CRA picture.
Changes inter slice types to P when the L1 reference list is empty and
to B otherwise.
In all-intra, all pictures are now IDR pictures with POC zero.
When using --gop=8 with an intra period greater than one, a single POC
would be skipped before every intra frame. This commit fixes the problem
by turning the intra frames into BLA frames with leading pictures when
using --gop=8.
