视频压缩编解码标准MPEG4商业级别的VC代码实现标准

TODO
====

This file lists the TODO items stll pending for the next release.


Active Items to work on:
------------------------

* update vfw & dshow decoder frontends
  - GUI isn't perfect for vfw
* update/fix CBR plugin
  - misses target bitrate, bitrate burst in static motion/high motion
    transitions
* bug hunting (ed.gomez/syskin)
  - xvidcore is still a place where bugs feel confortable
* docbook writing (every developer should contribute)
  - New API has to be documented.
* MMX MPEG4 quantization is unprecise. This is probably an inherent
  problem in some MMX opcode precision.


Already completed items:
------------------------

* remove divx4 api (ed.gomez)
* remove VOP_TYPE enumerations (peter)
* remove HINTed ME stuff (ed.gomez)
* xvid_image_t/xvid_gbl_convert_t (peter)
* xvid_global structs (peter)
* errors codes (peter)
* xvid_decoder structs (peter)
* apply encoder api changes "HEAPS" (peter)
* rawdec (use xvid_decraw instead) (ed.gomez)
* Support for GMC 3 warp points (christoph)
* New Qpel code (michael)
* ME splitting and ME improvements (syskin)
* New unix build process (ed.gomez)
* Move/clean/enhance 2pass code from vfw to core (ed.gomez)
* New thread/instance safe sse2 code (p.massimino)
* INSTALL guide for Unix and Win32 (ed.gomez)
* dshow static link to libxvidcore.lib (peter)
* update/fix Lumimasking (syskin)
* trellis for mpeg and relaxed optimization for big levels (skal)
* thread safe mpeg quantizing (michael)
* Interlacing for bvop and svop (syskin)
* YV12/I420/USER clarification (christoph)
* vfw and dshow link dynamically to xvidcore.dll (syskin)
* vfw bitrate calculator (peter)
* dshow configure from command line (peter)



ideas for v1.1 and beyond
-------------------------
libxvidcore
* video buffer verifier

vfw
* integrated Packed<->ISO converter
* vfw-ext api to get/set configuration parameters
* ICM_DECOMPRESSEX_* support

directshow
* manual aspect ratio setting (1:1, 4:3, 16:9, Custom)
* option to display libxvidcore version and bitstream ontop of video
  hopefuly, using smooth fonts, not image_printf().
