43TODO:
9f45d04d 44verify that everything workes as it should (how?)
3057fa66
A
45reduce the time wasted on the mem transfer
46implement dering
13e00528 47implement everything in C at least (done at the moment but ...)
3057fa66
A
48unroll stuff if instructions depend too much on the prior one
49we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?
50move YScale thing to the end instead of fixing QP
13e00528 51write a faster and higher quality deblocking filter :)
d5a1a995
MN
52do something about the speed of the horizontal filters
53make the mainloop more flexible (variable number of blocks at once
54 (the if/else stuff per block is slowing things down)
9f45d04d
MN
55compare the quality & speed of all filters
56implement a few simple deinterlacing filters
57split this huge file

660.1.3
67 bugfixes: last 3 lines not brightness/contrast corrected
68 brightness statistics messed up with initial black pic
69 changed initial values of the brightness statistics
70 C++ -> C conversation
71 QP range question solved (very likely 1<=QP<=32 according to arpi)
72 new experimental vertical deblocking filter
73 RK filter has 3dNow support now (untested)
13e00528

740.1.2
75 fixed a bug in the horizontal default filter
76 3dnow version of the Horizontal & Vertical Lowpass filters
77 mmx version of the Horizontal Default filter
78 mmx2 & C versions of a simple filter described in a paper from ramkishor & karandikar
79 added mode flags & quality2mode function
