New experiment: Perceptual Vector Quantization from Daala PVQ replaces the scalar quantizer and coefficient coding with a new design originally developed in Daala. It currently depends on the Daala entropy coder although it could be adapted to work with another entropy coder if needed: ./configure --enable-experimental --enable-daala_ec --enable-pvq The version of PVQ in this commit is adapted from the following revision of Daala: https://github.com/xiph/daala/commit/fb51c1ade6a31b668a0157d89de8f0a4493162a8 More information about PVQ: - https://people.xiph.org/~jm/daala/pvq_demo/ - https://jmvalin.ca/papers/spie_pvq.pdf The following files are copied as-is from Daala with minimal adaptations, therefore we disable clang-format on those files to make it easier to synchronize the AV1 and Daala codebases in the future: av1/common/generic_code.c av1/common/generic_code.h av1/common/laplace_tables.c av1/common/partition.c av1/common/partition.h av1/common/pvq.c av1/common/pvq.h av1/common/state.c av1/common/state.h av1/common/zigzag.h av1/common/zigzag16.c av1/common/zigzag32.c av1/common/zigzag4.c av1/common/zigzag64.c av1/common/zigzag8.c av1/decoder/decint.h av1/decoder/generic_decoder.c av1/decoder/laplace_decoder.c av1/decoder/pvq_decoder.c av1/decoder/pvq_decoder.h av1/encoder/daala_compat_enc.c av1/encoder/encint.h av1/encoder/generic_encoder.c av1/encoder/laplace_encoder.c av1/encoder/pvq_encoder.c av1/encoder/pvq_encoder.h Known issues: - Lossless mode is not supported, '--lossless=1' will give the same result as '--end-usage=q --cq-level=1'. - High bit depth is not supported by PVQ.
