Struct CompMedia 

pub struct CompMedia<'a> {
    pub fp: &'a dyn Fingerprinter,
    pub dims: &'a dyn Fn(&Path) -> Result<(u32, u32)>,
    pub profile: Option<ProbeProfile<'a>>,
    pub rate: Option<ProbeRate<'a>>,
}

What a comp’s lowering reads of its media: probed sizes (dims), camera profiles for camera: auto (profile; None: every source is display-referred), frame rates for time remaps (rate; None: a remap is an error) and fingerprints.

Fields

fp: &'a dyn Fingerprinter

dims: &'a dyn Fn(&Path) -> Result<(u32, u32)>

profile: Option<ProbeProfile<'a>>

rate: Option<ProbeRate<'a>>

Trait Implementations

impl Media for CompMedia<'_>

fn dims(&self, path: &Path) -> Result<(u32, u32)>

A video’s or still’s display size, px (rotation and HEIF grids applied).

fn identity(&self, path: &Path) -> Value

The file’s identity in keys (a fingerprint: path, size, modification time).

fn ffmpeg_build(&self) -> String

The ffmpeg build that runs filter nodes (in their keys).

fn content_hash(&self, path: &Path) -> Value

A small file’s contents in keys (a filter node’s LUTs, fonts, text files): by default its identity.

fn profile(&self, path: &Path) -> Result<Profile>

A video’s or still’s camera profile for camera: auto (Profile::detect_file).

fn video_rate(&self, path: &Path) -> Result<(f64, u64)>

A video’s average frame rate and frame count, for time remapping.

fn camera_lut(&self, profile: Profile) -> Result<Option<CameraLut>, Error>

profile’s camera LUT (None for display-referred profiles).
