Changes for 0.9.1 'Golden Eagle':
---------------------------------
0.9.1 is a middle-size revision of dav1d, adding notably 10b acceleration for SSSE3:
- 10/12b SSSE3 optimizations for mc (avg, w_avg, mask, w_mask, emu_edge),
prep/put_bilin, prep/put_8tap, ipred (dc/h/v, paeth, smooth, pal, filter), wiener,
sgr (10b), warp8x8, deblock, film_grain, cfl_ac/pred for 32bit and 64bit x86 processors
- Film grain NEON for fguv 10/12b, fgy/fguv 8b and fgy/fguv 10/12 arm32
- Fixes for filmgrain on ARM
- itx 10bit optimizations for 4x4/x8/x16, 8x4/x8/x16 for SSE4
- Misc improvements on SSE2, SSE4
0.9.0 is a major version of dav1d, adding notably 10b acceleration on x64.
Details:
- x86 (64bit) AVX2 implementation of most 10b/12b functions, which should provide
a large boost for high-bitdepth decoding on modern x86 computers and servers.
- ARM64 neon implementation of FilmGrain (4:2:0/4:2:2/4:4:4 8bit)
- New API to signal events happening during the decoding process
0.8.2 is a middle-size update of the 0.8.0 branch:
- ARM32 optimizations for ipred and itx in 10/12bits,
completing the 10b/12b work on ARM64 and ARM32
- Give the post-filters their own threads
- ARM64: rewrite the wiener functions
- Speed up coefficient decoding, 0.5%-3% global decoding gain
- x86 optimizations for CDEF_filter and wiener in 10/12bit
- x86: rewrite the SGR AVX2 asm
- x86: improve msac speed on SSE2+ machines
- ARM32: improve speed of ipred and warp
- ARM64: improve speed of ipred, cdef_dir, cdef_filter, warp_motion and itx16
- ARM32/64: improve speed of looprestoration
- Add seeking, pausing to the player
- Update the player for rendering of 10b/12b
- Misc speed improvements and fixes on all platforms
- Add a xxh3 muxer in the dav1d application
