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)
