Moves tests from .travis.yml to bash scripts in tests directory. Adds
the test scripts to tests/Makefile.am so that they are included when
running make check.
AVX2 filter functions read pixels in chunks of 8 or 16 bytes. At the end
of the block, the read goes out of the bounds of the pixels array. The
extra pixels do not affect the result.
Fixes valgrind complaining about the invalid reads by allocating 5 extra
pixels in kvz_get_extended_block_avx2
With low delay GOP structure, it is possible to use an intra period that
is not a multiple of the GOP structure length. Commit 00c9f52 changed
encoder_state_init_new_frame to reset POC on intra frames. GOP offset,
however, was not reset, resulting in invalid POCs and references for the
following frames.
This commit changes function kvz_encoder_feed_frame so that GOP offset
is correctly reset on intra frames.
When closing the encoder, the pictures stored in the input frame buffer
are freed by repeatedly calling kvz_encoder_feed_frame. If the encoder
was closed immediately after opening it, kvz_encoder_feed_frame would be
called with an unprepared encoder state. This would trigger an assert.
Fixed by changing kvz_encoder_feed_frame so that it does not require the
encoder state to be prepared.
Sets max_transform_hierarchy_depth_inter to 0 in SPS. This saves some
bits because split_transform_flag does not need to be coded for inter
blocks.
When SMP and AMP blocks are enabled the depth is set to 1 instead.
Otherwise inter split flag would default to 1 for SMP and AMP blocks,
resulting in an unnecessary transform split.
Changes kvazaar_close to stop all threads before freeing encoder states.
Fixes a crash when the encoder is closed before all pictures have been
encoded.
Changes kvazaar_close to free the remaining pictures in the the input
frame buffer. Fixes a memory leak when the encoder is closed while there
are pictures left in the buffer.
Replaces function kvz_intra_recon_lcu_luma and
kvz_intra_recon_lcu_chroma in intra.c with function kvz_intra_recon_cu.
The new function can handle reconstruction for both luma and chroma.
Removes some duplicated code.
Moves code for intra leaf transform block reconstruction from functions
kvz_intra_recon_lcu_luma and kvz_intra_recon_lcu_chroma to a new
function intra_recon_tb_leaf. Removes some duplicated code.
Changes functions encode_intra_coding_unit and encode_coding_tree to
take coordinate arguments in units of luma pixels instead of 8 px
blocks. This should make the code easier to understand.
Changes functions encode_transform_unit and encode_transform_coeff to
take coordinate arguments in units of luma pixels instead of 4 px
blocks. This should make the code easier to understand.
When kvazaar was built with crypto++ but running without using
encryption features, kvazaar attempted to delete an uninitialized crypto
handle. Fixed by setting the handle to NULL in kvz_encoder_state_init.
A CryptoPP::CFB_Mode<CryptoPP::AES>::Encryption was allocated at the
beginning of encoder_state_encode_leaf and was never freed. This commit
changes encoder_state_worker_encode_lcu to delete the CFB_Mode. Also
moves crypto handle from encoder_state_config_tile_t to encoder_state_t
so that it can be safely deleted without affecting other threads in the
same tile.
Moves the inline declaration of intra_mode_encryption before the type
and changes it to use the INLINE macro. Inline declaration after type
triggered a warning on GCC.
On Windows, the platform name (Win32 or x64) is used as the object
format parameter for vsyasm. However, vsyasm 1.3.0 expects the format
name to be in lower case. This commit changes vsyasm.props so that the
object format is converted to lower case.
Fixes#168.
Fixes the order of acquiring locks for the job and its dependency in
kvz_threadqueue_job_dep_add. The dependency is locked before the job
that depends on it. This is the same order as in threadqueue_worker.
Acquiring the locks in different order in kvz_threadqueue_job_dep_add
and threadqueue_worker would sometimes result in a deadlock.
When using --me-early-termination=sensitive, early termination of inter
search used to always return the starting point if no tested motion
vector was good enough to continue the search. This commit changes
early_termination to always return the best motion vector and cost
found.
Changes kvz_config_validate to output an error if the given QP is out of
range and changes kvz_set_picture_lambda_and_qp to clip the QP to the
valid range if is too large after applying QP offset from GOP structure.
Replaces functions kvz_quantize_lcu_luma_residual and
kvz_quantize_lcu_chroma_residual in transform.c with function
kvz_quantize_lcu_residual. The new function can handle any of the YUV
colors. Removes some duplicated code.
Changes the way coefficients are passed from kvz_search_lcu to
kvz_encode_coding_tree. Drops fields coeff_y, coeff_u and coeff_v in
videoframe_t and instead passes them through field coeff in
endoder_state_t.
