TODO: |
|
remove global/static vars |
|
reduce the time wasted on the mem transfer |
|
implement everything in C at least (done at the moment but ...) |
|
unroll stuff if instructions depend too much on the prior one |
|
we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4? |
|
move YScale thing to the end instead of fixing QP |
|
write a faster and higher quality deblocking filter :) |
|
make the mainloop more flexible (variable number of blocks at once |
|
(the if/else stuff per block is slowing things down) |
|
compare the quality & speed of all filters |
|
split this huge file |
|
border remover |
|
optimize c versions |
|
try to unroll inner for(x=0 ... loop to avoid these damn if(x ... checks |
|
smart blur |
|
commandline option for the deblock / dering thresholds |
|
put fastmemcpy back |
|
dont use #ifdef ARCH_X86 for the asm stuff ... cross compilers? (note cpudetect uses ARCH_X86) |
