60 | 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 | |
