Decoding options

Fields

bypass_filtering: c_int

if true, skip the in-loop filtering

no_fancy_upsampling: c_int

if true, use faster pointwise upsampler

use_cropping: c_int

if true, cropping is applied first

crop_left: c_int

left position for cropping. Will be snapped to even value.

crop_top: c_int

top position for cropping. Will be snapped to even value.

crop_width: c_int

width of the cropping area

crop_height: c_int

height of the cropping area

use_scaling: c_int

if true, scaling is applied afterward

scaled_width: c_int

final resolution width

scaled_height: c_int

final resolution height

use_threads: c_int

if true, use multi-threaded decoding

dithering_strength: c_int

dithering strength (0=Off, 100=full)

flip: c_int

Available on crate feature 0_5 only.

if true, flip output vertically

alpha_dithering_strength: c_int

Available on crate feature 0_5 only.

alpha dithering strength in [0..100]
