Enum gstreamer_video::VideoResamplerMethod

#[non_exhaustive]
pub enum VideoResamplerMethod {
    Nearest,
    Linear,
    Cubic,
    Sinc,
    Lanczos,
}

Different subsampling and upsampling methods

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Nearest

Duplicates the samples when upsampling and drops when downsampling

Linear

Uses linear interpolation to reconstruct missing samples and averaging to downsample

Cubic

Uses cubic interpolation

Sinc

Uses sinc interpolation

Lanczos

Uses lanczos interpolation
