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.
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.
Stops assuming that having cfg->gop_lowdelay set means that GOP
structure is used since it is possible that cfg->gop_lowdelay is true
but cfg->gop_len is zero. Adds checks for cfg->gop_len where needed.
Fixes a possible division by zero in kvz_encoder_feed_frame.
- 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 first frame was always qp51 due to gop_offset being -1 for the
first frame. This fix makes it so that bits are allocated as if it was
the last (high quality) frame from the previous GOP.
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)
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.
