|
*** build environment *** |
|
|
- portable makefile [DONE] |
|
|
more testing needed |
|
| 8 |
|
|
| 9 |
|
This ToDo list is not definitive : |
| 10 |
|
|
| 11 |
*** api *** |
++ Remove alpha code from stable tree |
|
- decore/encore2 wrappers; [DONE] |
|
| 12 |
|
|
| 13 |
- xvid_init() [DONE] |
* Find a co maintainer - [IN PROGRESS] |
| 14 |
handle cpu detection, yuv/dct lookup table init |
* Remove all BFrames stuff - [IN PROGRESS] |
| 15 |
return api version number |
* Remove all SMP stuff - [TODO] |
| 16 |
return core build number [build number should be incremented automatically, how?] |
* Remove all field-ME functions [TODO] |
| 17 |
|
|
| 18 |
|
|
| 19 |
*** common *** |
++ Fixes |
| 20 |
|
|
| 21 |
- mpeg-4 quantizer (quant4) testing [DONE] |
* Add all legal headers (same headers all over the sources) - [IN PROGRESS] |
| 22 |
- consder moving a modified mbprediction/mbdeprediction here [DONE] |
* Sort out who has main copyrigths on files - [TODO] |
| 23 |
|
* Check core reentrancy - [TODO] |
| 24 |
|
* Check the small mem problems reported by valgrind [TODO] |
| 25 |
|
|
| 26 |
- add [-2048,2048] to mmx dequant [DONE] |
++ ??? |
| 27 |
|
|
|
|
|
|
- mmx quant4 [DONE] |
|
|
- sse2: convert intel's idct/sad/comp apnotes to nasm [IN PROGRESS] |
|
|
- mlib |
|
|
|
|
|
|
|
|
*** image *** |
|
|
|
|
|
- sort out in/out & conversion func naming issues [DONE] |
|
|
maybe, in_yuv, in_yuyv, in_uyuv, in_rgbXX |
|
|
out_yuv, out_yuyv, out_uyuv, out_rgbXX |
|
|
|
|
|
- input flipping support |
|
|
output flipping support is not 'perfect'. |
|
|
using negative height is bad, best to have seperate vflip parameter |
|
|
|
|
|
- rgb24/32_mmx cause yellow dots to appear on left hand size |
|
|
(only visibile with high contrast colors) |
|
|
|
|
|
- rgb16. [DONE] |
|
|
can be done generically using r,g,b masks |
|
|
or just code for the popular 16bit formats 555, 565 |
|
|
|
|
|
- diff between basic-yuv and iso-yuv |
|
|
|
|
|
|
|
|
*** decoder *** |
|
|
|
|
|
- quant=1 encoder material appears "soft" [FIXED] |
|
|
- block based interpolation [DONE] |
|
|
|
|
|
- msmpeg-4 support... dont hold your breath [IN PROGRESS] |
|
|
best to write an entirely new 'decoder' than bolt stuff onto |
|
|
the existing one. |
|
|
|
|
|
- post processing [IN PROGRESS] |
|
|
|
|
|
- add basic mpeg4 stuff: |
|
|
- custom mpeg quant matrixes [DONE] |
|
|
- intra_dc_vlc_threshold [DONE] |
|
|
- quarterpel [in progress] |
|
|
- resync? |
|
|
|
|
|
- b-vops [IN PROGRESS] |
|
|
- figure out what todo with time codes, and fatal error |
|
|
|
|
|
|
|
|
|
|
|
*** encoder *** |
|
|
|
|
|
- purple mb block (rare) [FIXED] |
|
|
- coeff range checks need to be verified against mpeg-4 spec [DONE/PARTIAL] |
|
|
- dequants now clamp to [-2048,2047]. [DONE] |
|
|
- fdct_mmx clamps to [-2048,2047], it doesnt have to (but prevents overflows in mmx quantization) |
|
|
- quants _should_ clamp to [-127,127], but this introduces errors at low quant levels so we ignore it |
|
|
- idct _should_ clamp [-256,255], but its really unnessary overhead. |
|
|
|
|
|
- pmvfast bug fixing [DONE] |
|
|
|
|
|
- quater pixel motion search [IN PROGRESS] |
|
|
|
|
|
- bidirectional coding [IN PROGRESS] |
|
|
|
|
|
- global motion compensation |
|
|
|
|
|
- redo coefficient thresholding like described in H26L |
|
|
|
|
|
- 'smearing bug' when motion occurs in straight vertical direction ( |
|
|
http://www.videocoding.de/forum/viewtopic.php?topic=71&forum=2&6 ) |
|
|
coefficient thresholding problems? [FIXED/REMOVED] |
|
|
|
|
|
- better luminance masking [DONE] |
|
|
|
|
|
- further improve adaptive quantisation, maybe implement JND maps |
|
|
|
|
|
- use N_VOP when a interframe is entirely composed of ublks |
|
|
& frame dropping. eg. simple ublk threshold |
|
|
|
|
