- [2005-3-29]
- New function:
- 1, B frame deblock. [decoder]
- 2, Add sse2/sse/mmx support for Pixel_avg. [encoder/decoder]
- 3, rewrite sad + interpolation asm. [encoder]
- 4, cabac encoder and decoder support.
- 5, rewrite deblock for speed.
- 6, rewrite p skip detection routine. [encoder]
- 7, scene detection added. [encoder]
- 8, dshow wrapper update.
- Fixed bugs:
- 1, bitstream rbsp_training_bits bug. [encoder]
- 2, ratecontrol for b slice. [encoder]
- 3, fixed direct mode for b slice. [encoder]
- 4, bitstream decoder may be error between emulation prevention code. [decoder]
- 5, reorder frames bug. [decoder]
- [2004-12-15]
- 1, i16x16 decoder support
- 2, dshow encoder + decoder + splitter support
- [2004-12-3]
- 1, new fast interpolation introduced
- 2, p slice decoder complete
- 3, port to linux
- [2004-11-17]
- 1, b slice 16x8 + 8x16 introduced
- 2, multiple previous frames used for inter introduced(speed dropped)
- [2004-11-9]
- 1, introduce new flag: USE_INTRAININTER, when it is off, speed may be up 5 fps(3ks chenm)
- 2, redesign plugin structure, stat(include psnr now can display by set the enable psnr in
- enconfig.txt)
- 3, change the header file t264.h and then it is friendly to use maybe
- 4, change the directory layout, decoder will import
- [2004-11-6]
- b frame partial implement
- [2004-10-26]
- 1, subpel search increase from 4 pel to 8 pel
- 2, ratecontrol can be enble by set enable rate control to 1 in enconfig.txt
- in T264.exe or set bitrate great than 0 in T264 dshow encoder.
- [2004-10-22]
- 1, optimized deblock filter
- 2, optimized detect p-skip subroutine
- 3, add i4x4 mode3-8, except mode 3 & 7
- 4, add interpolate_h/v_sse2, gain minor speed
- 5, update ratecontrol mad model, but still not satisfied
- 6, update me thresholds, increase the compression ratio
- 7, limit ratecontrol min/max qp to prevent the quality decrease fearfully
