8  *** build environment ***  This ToDo list is not definitive :
9    
10  - portable makefile [DONE]  ++ Remove alpha code from stable tree
11    
12  - QuickTime frontend  * Find a co maintainer - [IN PROGRESS]
13  - Java frontend  * Remove all BFrames stuff - [TODO]
14    * Remove all SMP stuff - [TODO]
15    * Remove all field-ME functions [TODO]
16    
17    
18  *** api ***  ++ Fixes
 - decore/encore2 wrappers; [DONE]  
 - xvid_init() [DONE]  
         handle cpu detection, yuv/dct lookup table init [DONT]  
         return api version number [DONE]  
         return core build number [HALTED; how?]  
19    
 *** common ***  
   
 - mpeg-4 quantizer (quant4) testing [DONE]  
 - consder moving a modified mbprediction/mbdeprediction here [DONE]  
 - add [-2048,2048] to mmx dequant [DONE]  
 - mmx quant4 [DONE]  
 - sse2 [DONE]  
   
 - sse2 quant4  
 - mlib  
   
   
 *** image ***  
   
 - sort out in/out & conversion func naming issues [DONE]  
 - rgb16. [DONE]  
   
   
 - 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)  
   
 - investigate difference between basic-yuv and iso-yuv  
   
   
 *** decoder ***  
   
 - quant=1 encoder material appears "soft" [FIXED]  
 - block based interpolation [DONE]  
   
 - add basic mpeg4 stuff:  
         - custom mpeg quant matrixes [DONE]  
         - intra_dc_vlc_threshold [DONE]  
         - quarterpel  [in progress]  
         - resync?  
   
 - msmpeg-4 support [IN PROGRESS]  
 - post processing [IN PROGRESS]  
 - b-vops [IN PROGRESS]  
   
 - proper handling of time codes and fatal/non-fatal errors  
   
   
 *** encoder ***  
   
 - purple mb block (rare) [FIXED]  
 - coeff range checks need to be verified against mpeg-4 spec [DONE]  
         - 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]  
 - '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]  
   
   
 - quater pixel motion search [IN PROGRESS]  
 - bidirectional coding [IN PROGRESS]  
 - virtualdub support [IN PROGRESS]  
   
 - global motion compensation  
 - redo coefficient thresholding like described in H26L  
 - 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  
   
   
 *** gpl conversion ***  
   
 mbdecoding.c [REPLACED]  
 encoder.c       [REPLACED]  
 mbmotionestcomp.c       [REPLACED]  
 mbcoding [REPLACED]  
 putvlc.c [REPLACED]  
 ratecontol.c [REPLACED]  
20    * Add all legal headers (same headers all over the sources) - [TODO]
21    * Sort out who has main copyrigths on files - [TODO]
22    * Check core reentrancy - [TODO]
