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.
Both the thread queue and the encoder states hold pointers to the thread
queue jobs. It is possible that a job is removed from the thread queue
and freed while the encoder state is still using it. This commit adds
reference counting to threadqueue_job_t in order to fix the problem.
Fixes#161.
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.
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.
- 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.

This moves the interlacing from CLI code to api->encoder_encode, in
order to make it possible to use field coding through the lib API.
The field order is now determined per frame, as FFmpeg gives it per
frame and it's signaled per frame.
As a side effect, the CLI also now prints info from frames instead of
fields. While we might want to extend the API in the future to allow
printing of more detailed information about fields, for now it's
more important that the CLI uses the real lib API.
PSNR calculation for interlaced frames disabled until we have a way to
avoid deinterlacing the frame when it's not necessary.
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.
Adds a new output parameter info_out to encoder_encode. It returns
a struct containing information about the encoded frame, including POC,
QP and slice type.
A call to kvz_threadqueue_waitfor caused the tqj_bitstream_written field
of the previous encoder state to become a dangling pointer, subsequently
causing an assertion to fail. This would only occur when the encoder
state used for a new frame was not the last finished one.
Fixed by setting tqj_bitstream_written to NULL after the job is done and
removing unnecessary calls to kvz_threadqueue_waitfor.
- Removes all bitstream types.
- Changes encoder_encode to return the encoded data as list of chunks.
- Moves writing of the encoded data to the main function.
- 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.
Adds function image_copy_ref to image module for getting a new reference
to an image. It can be used instead of image_make_subimage when the
sizes of the original and the subimage are same.
