Moves SAO reconstruction into encoder_state_worker_encode_lcu instead of
doing it in a separate step for the whole CTU row. Reconstruction of the
rightmost 10 pixels and bottommost 10 pixels of a CTU is delayed until
the neighboring CTU has been deblocked.
Doing SAO for the whole CTU row at a time caused unnecessary inter-CTU
dependencies when using WPP and OWF. The first CTU of a row would need
to wait until SAO was done for the row below in the previous frame.
Moving SAO reconstruction to immediately after deblocking each CTU fixes
this problem.
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.
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.
Some of the fields in encoder_control_t were simply copies of the
corresponding fields in kvz_config. This commit drops the copied fields
in favor of using the fields in encoder_control_t.cfg directly.
Adds field lcu_stats to encoder_state_config_frame_t. The following data
is recorded for each LCU:
- number of bits
- squared cost
- used lambda value
- alpha parameter used for rate control
- beta parameter used for rate control
When rate control is enabled, enable cu_qp_delta_enabled_flag in PPS
with diff_cu_qp_delta_depth set to 0. Also adds code for writing the QP
deltas and a new cabac context.
Adds fields lambda, lambda_sqrt and qp to encoder_state_t. Drops field
cur_lambda_cost_sqrt from encoder_state_config_frame_t and renames
cur_lambda_cost to lambda.
- Moves allocation of the reconstructed picture after the source picture
is set.
- Extracts main state initialization to a separate function from
encoder_state_new_frame.
- Changes kvz_encoder_feed_frame to return the frame.
- Renames some functions to better match their purpose.
The includes should make more sense now and not just happen to compile
due to headers included from other headers.
Used a modified version of IWYU. Modifications were to attribute int8_t
and so on to stdint.h instead of sys/types.h and immintrin.h instead of
more specific headers.
include-what-you-use 0.7 (git:b70df35)
based on clang version 3.9.0 (trunk 264728)
I was a bit unclear about exactly what happens and when regarding SAO
and deblocking when we do frame-parallel WPP parallelism, so I checked
and commented the bits that were unclear to me.
Prevents a conflict with config.h and src/config.h so that the config.h
generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.
Add module information to all header files.
Update all header file documentations to briefly say what they are, and
to use the javadoc format so the brief actually gets included into the
doxygen documentation.
Remove \file from implementation files, in order to not repeat the info
from the header files.
Add files under strategies and tools to Doxygen and update the Doxygen
settings to be just plain better.
Make README be the main page of Doxygen documentation.
Changes main function to compute frame PSNR by calling
kvz_videoframe_compute_psnr directly with the source and reconstructed
pictures returned from encoder_encode.
The code for building the reference picture lists was duplicated in
functions encoder_state_ref_sort and print_frame_info. This commit moves
it to a new function kvz_encoder_get_ref_lists. Also makes
encoder_ref_insertion_sort static since it is not used outside the
encoderstate module any more.
- Replaces read_one_frame by encoder_feed_frame.
- Adds field "prepared" to encoderstate_t to indicate that
encoder_next_frame has been called.
- Input frames are read in the main function and passed to
encoder_encode.
- Move image_t and pixel_t to the kvazaar.h API.
- Try and arrange things such that image_t can be used as input and
output for encoding.
Conflicts:
src/encmain.c
- CLI stuff is moved to either cli-module or to main function.
- OWF stuff is made more explicit by counting the frames instead of
communicating through encoder_state_t.stats_done.
