TODO:
|
| 61 |
reduce the time wasted on the mem transfer
|
| 62 |
unroll stuff if instructions depend too much on the prior one
|
| 63 |
move YScale thing to the end instead of fixing QP
|
| 64 |
write a faster and higher quality deblocking filter :)
|
| 65 |
make the mainloop more flexible (variable number of blocks at once
|
| 66 |
(the if/else stuff per block is slowing things down)
|
| 67 |
compare the quality & speed of all filters
|
| 68 |
split this huge file
|
| 69 |
optimize c versions
|
| 70 |
try to unroll inner for(x=0 ... loop to avoid these damn if(x ... checks
