2010-09-02 v0.9.2 - Enhancements: Disable frame dropping by default Improved multithreaded performance Improved Force Key Frame Behaviour Increased rate control buffer level precision Fix bug in 1st pass motion compensation ivfenc: correct fixed kf interval, --disable-kf - Speed: Changed above and left context data layout Rework idct calling structure. Removed unnecessary MB_MODE_INFO copies x86: SSSE3 sixtap prediction Reworked IDCT to include reconstruction (add) step Swap alt/gold/new/last frame buffer ptrs instead of copying. Improve SSE2 loopfilter functions Change bitreader to use a larger window. Avoid loopfilter reinitialization when possible - Quality: Normalize quantizer's zero bin and rounding factors Add trellis quantization. Make the quantizer exact. Updates to ARNR filtering algorithm Fix breakout thresh computation for golden & AltRef frames Redo the forward 4x4 dct Improve the accuracy of forward walsh-hadamard transform Further adjustment of RD behaviour with Q and Zbin. - Build System: Allow linking of libs built with MinGW to MSVC Fix target auto-detection on mingw32 Allow --cpu= to work for x86. configure: pass original arguments through to make dist Fix builds without runtime CPU detection msvs: fix install of codec sources msvs: Change devenv.com command line for better msys support msvs: Add vs9 targets. Add x86_64-linux-icc target - Bugs: Potential crashes on older MinGW builds Fix two-pass framrate for Y4M input. Fixed simple loop filter, other crashes on ARM v6 arm: fix missing dependency with --enable-shared configure: support directories containing .o Replace pinsrw (SSE) with MMX instructions apple: include proper mach primatives Fixed rate control bug with long key frame interval. Fix DSO link errors on x86-64 when not using a version script Fixed buffer selection for UV in AltRef filtering
