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) |
|
|
|
Special versions: fast Y 1:1 scaling (no interpolation in y direction) |
|
|
|
TODO |
|
more intelligent missalignment 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 |
|
deglobalize yuv2rgb*.c |
