NOTES
|
|
Special versions: fast Y 1:1 scaling (no interpolation in y direction)
|
|
|
|
TODO
|
|
more intelligent misalignment avoidance for the horizontal scaler
|
|
write special vertical cubic upscale version
|
|
optimize C code (YV12 / minmax)
|
|
add support for packed pixel YUV input & output
|
|
add support for Y8 output
|
|
optimize BGR24 & BGR32
|
|
add BGR4 output support
|
|
write special BGR->BGR scaler
