+2011-08-02 v0.9.7 "Cayuga"
+ Our third named release, focused on a faster, higher quality, encoder.
+
+ - Upgrading:
+ This release is backwards compatible with Aylesbury (v0.9.5) and
+ Bali (v0.9.6). Users of older releases should refer to the Upgrading
+ notes in this document for that release.
+
+ - Enhancements:
+ Stereo 3D format support for vpxenc
+ Runtime detection of available processor cores.
+ Allow specifying --end-usage by enum name
+ vpxdec: test for frame corruption
+ vpxenc: add quantizer histogram display
+ vpxenc: add rate histogram display
+ Set VPX_FRAME_IS_DROPPABLE
+ update configure for ios sdk 4.3
+ Avoid text relocations in ARM vp8 decoder
+ Generate a vpx.pc file for pkg-config.
+ New ways of passing encoded data between encoder and decoder.
+
+ - Speed:
+ This release includes across-the-board speed improvements to the
+ encoder. On x86, these measure at approximately 11.5% in Best mode,
+ 21.5% in Good mode (speed 0), and 22.5% in Realtime mode (speed 6).
+ On ARM Cortex A9 with Neon extensions, real-time encoding of video
+ telephony content is 35% faster than Bali on single core and 48%
+ faster on multi-core. On the NVidia Tegra2 platform, real time
+ encoding is 40% faster than Bali.
+
+ Decoder speed was not a priority for this release, but improved
+ approximately 8.4% on x86.
+
+ Reduce motion vector search on alt-ref frame.
+ Encoder loopfilter running in its own thread
+ Reworked loopfilter to precalculate more parameters
+ SSE2/SSSE3 optimizations for build_predictors_mbuv{,_s}().+ Make hor UV predict ~2x faster (73 vs 132 cycles) using SSSE3.
+ Removed redundant checks
+ Reduced structure sizes
+ utilize preload in ARMv6 MC/LPF/Copy routines
+ ARM optimized quantization, dfct, variance, subtract
+ Increase chrow row alignment to 16 bytes.
+ disable trellis optimization for first pass
+ Write SSSE3 sub-pixel filter function
+ Improve SSE2 half-pixel filter funtions
+ Add vp8_sub_pixel_variance16x8_ssse3 function
+ Reduce unnecessary distortion computation
+ Use diamond search to replace full search
+ Preload reference area in sub-pixel motion search (real-time mode)
+
+ - Quality:
+ This release focused primarily on one-pass use cases, including
+ video conferencing. Low latency data rate control was significantly
+ improved, improving streamability over bandwidth constrained links.
+ Added support for error concealment, allowing frames to maintain
+ visual quality in the presence of substantial packet loss.
+
+ Add rc_max_intra_bitrate_pct control
+ Limit size of initial keyframe in one-pass.
+ Improve framerate adaptation
+ Improved 1-pass CBR rate control
+ Improved KF insertion after fades to still.
+ Improved key frame detection.
+ Improved activity masking (lower PSNR impact for same SSIM boost)
+ Improved interaction between GF and ARFs
+ Adding error-concealment to the decoder.
+ Adding support for independent partitions
+ Adjusted rate-distortion constants
+
+
+ - Bug Fixes:
+ Removed firstpass motion map
+ Fix parallel make install
+ Fix multithreaded encoding for 1 MB wide frame
+ Fixed iwalsh_neon build problems with RVDS4.1
+ Fix semaphore emulation, spin-wait intrinsics on Windows
+ Fix build with xcode4 and simplify GLOBAL.
+ Mark ARM asm objects as allowing a non-executable stack.
+ Fix vpxenc encoding incorrect webm file header on big endian
+
+
