Struct WebpEncodeSettings 

pub struct WebpEncodeSettings {
    pub quality: u8,
    pub max_fps: u32,
    pub max_width: Option<u32>,
    pub lossless: bool,
    pub compression_level: u8,
}

Encoder settings for the animated WebP cover derived from a clip’s MP4 preview.

The Default turns encoder effort off (compression level 0) so a full-resolution clip encodes well under the ffmpeg timeout, since full effort can take minutes.

Fields

quality: u8

Lossy encoder quality, 0-100 (higher is better and larger). Ignored when lossless is set.

max_fps: u32

Cap on the output frame rate; a faster source is downsampled to this.

max_width: Option<u32>

Optional cap on the output width in pixels: Some(w) scales a wider source down keeping its aspect ratio (never upscaling), while None keeps the source resolution.

lossless: bool

Encode losslessly (much larger); off by default.

compression_level: u8

Encoder effort, 0-6 (higher is smaller and slower). 0 by default, because full effort can take minutes on a full-resolution clip and exceed the transcode timeout.

Trait Implementations

impl Clone for WebpEncodeSettings

fn clone(&self) -> WebpEncodeSettings

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for WebpEncodeSettings

impl Debug for WebpEncodeSettings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for WebpEncodeSettings

fn default() -> Self

Returns the “default value” for a type.

impl Eq for WebpEncodeSettings

impl PartialEq for WebpEncodeSettings

fn eq(&self, other: &WebpEncodeSettings) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
