There was an off by one error in the dependance setting code, which
resulted in dependencies not being set resulting in checksum errors.
For example if ref_neg=1 and owf=1.
Moves sao search from function encoder_state_worker_encode_lcu in
encoderstate.c to function kvz_sao_search_lcu in sao.c. Makes functions
kvz_init_sao_info, kvz_sao_search_chroma and kvz_sao_search_luma static
since they are no longer used outside sao.c.
CU data was being copied to the wrong place in the reference frames
cu_array, which led to uninitialized data being used as a starting
point for motion vector search.
Fixes#99.
Add dependency to the reference frame instead of the previous frame,
in order to allow more frames to be encoded in parallel when temporal
stepping >1 in LP-gop (such as --gop=lp-g8d4r1t2).
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.
Remove the need to count the coefficients by populating the significant
coefficient group map first and finding the last coefficient from the
last group afterward. The speedup is about 2% on ultrafast.
The previous version of this patch was reverted due to a bug, which
has now been fixed.
This reverts commit 25462124f8.
That commit broke the bitstream. If it's not good enough to push on Friday
night, it's probably not good enough on Monday morning either.

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.
This bug caused a single tiles worth of lcu_info_t structs to be copied
unnecessarily for every LCU in the frame. This obviously caused huge
memory bandwidth issues when coding large frames without tiles. The
effect was minimized somewhat with a large number of tiles, because
only the current tile was copied.
From context it is clear that this piece of code was supposed to copy
a single tile or frame, once the frame was done, but because it was
placed in a function which is called for every LCU, it copied the data
for the LCU, but also lots of extra stuff.
The fix is to copy only the current LCU instead of the whole tile.
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.
