Make the library code not depend to the y4m crate.

* Handle profiles and chroma sampling in sequence header

* Move y4m::Colorspace to ChromaSampling mapping to rav1e.rs

Raphaël Zumer authored 6 years ago and Thomas Daede committed 6 years ago

* Attempt to process 10-bit Y4M input

Currently compiles, encodes and decodes with desynchronization

* Use high bit depth quantization tables

* Move context::clamp() to util.rs

* Fix partition context initialization for high bit depth

* Enable and test 10-bit input

* Add 10- and 12-bit test clips to build.sh

Commented out by default, to enable as needed for local testing.

* Use the same bit depth as y4m_dec for y4m_enc

* Fix benchmark module compilation

* Fix high bit depth test encoding in 8-bit

* Fix header syntax for 12-bit 4:2:0 input

* Enable and test 12-bit input

* Reflect 12-bit support in README.md

* Keep the default C420jpeg color space in y4m_encoder

* Do not allow reconstruction output at high bit depths

* Fix reconstruction output at high bit depths

* Clean up reconstruction copy to frame buffers

Add a check for reconstructed vs decoded image difference on each build in build.sh

Clang is needed in order to run integration tests. Fixes #122.

Block boundary calculation is correct by accident-- make it correct on purpose.

Split analysis and filtering of CDEF superblocks so that RDO can do a
single find_dir before a number of filter tests at diffreretn
strengths.

Rebase without eliminating high-bitdepth stubs in functions.

Superblocks are 16 blocks wide, not 8.  Use the MAX_MIB_SIZE constant.

Implement basic cdef RDO, using cdef_dist for luma and sse for chroma

Implement SuperBlock centered CDEF computation
convert cdef_filter_frame to use SuperBlock-level computation
Add rdo_cdef_decision placeholder

This reverts commit 8c545350.

We can't guarantee we meet a level, so choose level 31 for now
which has no constraints.

* Improve block bounds checking in CDEF

The block bounds calculation in CDEF was doing nothing due to a
calculation error; due to misunderstanding why, a second, moredetailed
guard was added later that should have been unneccessary.

Correct the earlier/easier check to function properly, remove the more
complex and now unneccessary later guard.

* Move CDEF strength calculaiton outside block loop

Basic CDEF strength is signaled and calculated by superblock; no need
to repeat for each block

Monty Montgomery authored 6 years ago and Thomas Daede committed 6 years ago

Implement split partition encode with 'everything up to the CDEF
strength' and 'everything after the CDEF strength' coded in parallel
separate Writers, such that the CDEF strength can be determined at the
end of frame encode.

Does not yet perform the CDEF RDO.

I needed to same more information than I thought for the WriterRecorder---
local range state was not being used properly during replay.

Yushin Cho authored 6 years ago and Thomas Daede committed 6 years ago

If tune=Psychovisual is used, min partition size is enforced to 8x8.

* Add WriterCounter to EC

Only counts bits, stores nothing.  This is for throwaway cost analysis
decisions.

* Convert RDO to using throwaway WriterCounter

Instead of checkpoint/rollback on a master Writer, use throwaway
WriterCounter instances in RDO cost computaiton

* Add a bitstream writer record/replay abstraction

Allows encoding piecemeal, out of order, or in parallel; a recording
writer can be played back into a master bitstream range encoder.

* Reimplement od_ec_enc and Writer, add record/playback

Flatten od_ec_enc and Writer, as one was a thin wrapper for the other
Reimplement range encoding writer as a Writer trait and encoding backend
Reimplement recording as a second backend to same Writer trait

It has been wrong when SB is partitioned.

Yushin Cho authored 6 years ago and Yushin Cho committed 6 years ago

Inter mode prediction can be done for a whole partition,
instead of each tx-block.

TODO: Fix the plane_offset() function of BlockOffset struct for chroma
planes, so that bo.plane_offset() can be directly and conveniently
called instead of using a block of long codes in several places.

* Document pkg-config dependency

* Document dependencies on Windows

* Support build on Windows

Use smaller rounding offset in inter blocks to produce more
zero coefficients

Cargo would try to compile each file at the root of benches/ as
stand alone benchmark.

Disable the behaviour.
