DCTFilter (renewed)
https://github.com/HomeOfVapourSynth...ynth-DCTFilter
Well, the existing DCTFilter is *a bit* slow, therefore here comes the new one. I simply use the DCT/IDCT transforms from FFTW and nothing fancy. The implementation of DCT/IDCT in FFTW is inefficient, hence it's still slower than AviSynth's equivalent, but at least 3~7 times faster than the old one. |

Just did a quick test with my fairly heavy processing script to see how it fares with just this switch (and changing the dct call in Deblock_QED since you kept the old filename but not the old namespace/function name)
Code:
Old vspipe64.exe -s 2000 -e 9999 -p 42.vpy . Output 8000 frames in 559.36 seconds (14.30 fps) New vspipe64.exe -s 2000 -e 9999 -p 42.vpy . Output 8000 frames in 483.02 seconds (16.56 fps) |
