Ari Koivula 4a0121ac42 Add --roi parameter
Adds region of interest coding capability.

Works by reading a file of delta QP values which will then be applied
to each frame at LCU level.

Ari Koivula 6f61836989 Refactor kvz_rdoq_sign_hiding
Rename and reorder everything to make more sense.

- Moved input tables into their own struct and renamed them to what
  they actually represent.
- Renamed pretty much every variable to comform to our style and
  to make sense.
- Removed the lastCG stuff, as the function already gets passed the
  last coeff anyway. (it was named width, what the hell?)

Ari Koivula a85390d0ac Clean up code using the fixed point frac bit tables
This is to prepare for changing the code using the floating point table
to use the fixed point table instead.

This also allows reducing the size of the fractional part, which was
useful for finding every place where the the fixed point presentation
is relied upon.

Ari Koivula 24a69c7467 Refactor luma deblocking
Changes luma deblocking to use gather and scatter instead of reading
to and writing from here and there in memory. Should make them
faster and easier to vectorize, or at least cleaner.

Splits strong and weak luma deblocking to two functions, as they have
almost nothing in common.

Arttu Ylä-Outinen c219d3cd94 Fix deblock when CU QP delta is enabled
Fixes deblock functions so that they use the correct QP for the filtered
edge. Adds field qp to cu_info_t.
2017-01-11 15:53:22 +09:00
Arttu Ylä-Outinen 82a98180e4 Clip LCU lambda to reduce quality fluctuation
Limits lambdas for each LCU based on the computed lambda from the
previous frame and the frame-level lambda.
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen 93172fd251 Use separate alpha, beta and lambda for each LCU
Changes rate control to use the alpha and beta values stored in
lcu_stats_t instead of the frame-level values when selecting lambda and
QP for an LCU.
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen 3af4e9cc8a Allocate bits separately for each LCU
Bits are allocated based on the costs of the LCUs in the previous
completely coded frame.

Breaks deblock when rate control is used.
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen ff5e5ec6d4 Record info about coded LCUs
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
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen 2a4243acbe Refactor rate control
Moves all code related to setting QP and lambda values to rate_control
module.
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen 71633889ce Enable CU QP delta when using 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.
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen 640ff94ecd Use separate lambda and QP for each LCU
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.

Arttu Ylä-Outinen 435c387357 Refactor rate control
- Defines MIN_LAMBDA and MAX_LAMBDA constants.
- Moves resetting state->frame->cur_gop_bits_coded to rate_control.c.
- Changes gop_allocate_bits to return the number of bits allocated like
  pic_allocate_bits does.

Arttu Ylä-Outinen 6c4f2d196a Move fields from encoder_state_t to frame
Moves fields prepared and frame_done from encoder_state_t to
encoder_state_config_frame_t.

Arttu Ylä-Outinen db5e750c7f Fix --threads=auto
When --threads=auto was given on the command line, cfg->threads was
actually set to zero, disabling threads altogether. Fixed to set
cfg->threads to -1, so that the number of threads is chosen
automatically.

Ari Koivula a9e45efcfc Add a fast lane for byte-aligned bitstream writes
The CABAC engine only writes to the bitstream when it has a full byte.
These writes are also always byte-aligned, so there is no need to even
check for stream alignment.

Speedup was around 3% with ultrafast and low QP.

Ari Koivula b8a618e666 Fix problems with >8 bit input
Enforce bit depth promised by --input-bitdepth to avoid crashes when
larger values are provided.

Do endianess byte swap for all bytes when the buffer gets extended
to multiple of 8 pixels, and not just the number of input pixels.

Don't swap bytes on a little-endian system.

instead of the width of the buffer.

Ari Koivula 0c41c2ebd6 Make CLI set PTS for each input picture
This value is not represented in the HEVC bitstream, which is why it
