NOTES
|
|
|
|
known BUGS with known cause (no bugreports please!, but patches are welcome :) )
|
|
horizontal fast_bilinear MMX2 scaler reads 1-7 samples too much (might cause a sig11)
|
|
|
|
Supported output formats BGR15 BGR16 BGR24 BGR32 YV12
|
|
BGR15 & BGR16 MMX verions support dithering
|
|
Special versions: fast Y 1:1 scaling (no interpolation in y direction)
|
|
|
|
TODO
|
|
more intelligent missalignment avoidance for the horizontal scaler
|
|
dither in C
|
|
change the distance of the u & v buffer
|
|
Move static / global vars into a struct so multiple scalers can be used
|
|
write special vertical cubic upscale version
|
|
Optimize C code (yv12 / minmax)
