Struct VideoSource

Source

pub struct VideoSource { /* private fields */ }

Expand description

A video file decoded natively.

Implementations§

Source §

impl VideoSource

Source

pub fn open(path: &Path, options: Options) -> Result<VideoSource, Error>

Opens path with options (probing it once); errors carry the decoder’s reason, including how to install ffmpeg when it is needed and missing.

Source

pub fn video(&self) -> &VideoInfo

The decoder’s view of the file.

Trait Implementations§

Source §

impl FrameSource for VideoSource

Available on crate feature decode only.

Source §

fn info(&self) -> &MediaInfo

Source §

fn frames(&mut self) -> Result<Frames<'_>, SourceError>

Starts a read from the first frame.

Source §

fn sparse_frames(&mut self, wanted: &[bool]) -> Result<Frames<'_>, SourceError>

Like FrameSource::frames, but a frame whose entry in wanted is false (or past its end) may come without pixels (an empty rgba), which saves converting it. The default converts every frame.
