- It is far from complete, anyway :
-
-General:
---------
- Encoder:
- ########
-
- * CABAC: check if adaptive model is really working. (I didn't see any improvments)
-
- * Field support : no and I probably won't do it.
-
- * Slice A/B/C (partion): is there any interest doing it ? (Shouldn't be hard).
- - extend x264_t
- - review x264_macroblock_write_cavlc
-
- * Intra encoding:
- - in I_4x4 mode, some predict mode aren't tested and not supported :
- when some pixels around are unavailble but could be predicted from
- others. (see the norm)
-
- * Inter coding:
- - D_4x8 D_8x4 and D_4x4 ME P block -> done but too slow.
- - B_SUB8x8 types.
- - better SKIP detection.
- - long terme ?
- - ...
-
- * B frame: B_L0/L1/BI/SKIP/DIRECT work (need more testing).
- -> adaptive placement of B-frames
- -> look at weighted prediction (should give better result)
- -> better analyse algo (as always ;)
- -> joint motion estimation of BI types
-
- * Speed issue (oprofile is your friend)
- - mc.c:30% and pixel.c:20% (mc is used by ME)
- - Motion Estimation -> try better/faster algos.
- - loop filter
- - stream writing (bs)
- - ...
-
- * Time spent: (test file: 720x576, mmx, mmxext)
- CAVLC: analyse=73% encode=15% write=4% filter=6%
- CABAC: analyse=69% encode=16% write=8% filter=5%
-
- * Limitations:
- - frame width/height %16 == 0 only.
-
- * ...
-
- Decoder:
- ########
-
- * Currently decoder/* won't even compile, and anyway is unusable.
-
- Build:
- ######
- * Finish to port gcc inlined asm to nasm file.
-
-Coding issue:
--------------
- * table : somes are duplicated -> find a solution (easy).
- * documentations ? (mouaaaarfff ;)
- * ...
