Enum VideoSource 

pub enum VideoSource {
    FrameDir {
        frames: Vec<PathBuf>,
        fps: f64,
    },
    Y4m {
        path: PathBuf,
        info: Y4mInfo,
    },
}

A silent video given as decoded frames: a directory of images with an explicit frame rate, or a Y4M stream (ffmpeg -i in.mp4 -pix_fmt yuv420p out.y4m). mp4 decoding is out of scope for v1.

Implementations

impl VideoSource

pub fn frame_dir(dir: &Path, fps: f64) -> Result<Self, String>

Every image file of dir (png/jpg/jpeg/webp/gif/ppm), in natural name order, played at fps.

pub fn y4m(path: &Path) -> Result<Self, String>

Index a Y4M file (8-bit 4:2:0 / 4:2:2 / 4:4:4 / mono).

pub fn open(path: &Path, fps: Option<f64>) -> Result<Self, String>

A directory (needs fps) or a .y4m file (its own rate; an explicit fps overrides it).

pub fn frame_count(&self) -> usize

pub fn fps(&self) -> f64

pub fn read_frame(&self, idx: usize) -> Result<RgbFrame, String>

Decode frame idx to RGB.

Trait Implementations

impl Clone for VideoSource

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VideoSource

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

Formats the value using the given formatter.
