Arttu Ylä-Outinen 382636de55 Fix handling too large QPs 
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.
 2017-05-17 12:41:51 +03:00
Arttu Ylä-Outinen 79cb3a2fd3 Permit negative QP deltas in ROI 
Delta QPs should not be arbitrarily restricted to positive values.

Arttu Ylä-Outinen 51786eda67 Drop redundant fields in encoder_control_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.
 2017-02-09 14:05:28 +09:00
Arttu Ylä-Outinen e78a8dfcf5 Copy the kvz_config passed to encoder_open 
The kvz_config struct is created by the user but kvazaar keeps a pointer
to it. It is easy to break things by modifying the configuration outside
kvazaar. In addition, kvazaar modifies the struct even though it is has
a const modifier.

This commit changes the field cfg in encoder_control_t to be a copy of
the kvz_config struct instead of a pointer, removing modifications to
the const struct and allowing users to do whatever they want with it
after opening the encoder.

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.

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
