Struct VideoScaler

Source 
pub struct VideoScaler { /* private fields */ }
Expand description

A scaler is a wrapper around an SwsContext. Which is used to scale or transform video frames.

Implementations§

Source§

impl VideoScaler

Source

pub fn new( input_width: i32, input_height: i32, incoming_pixel_fmt: AVPixelFormat, width: i32, height: i32, pixel_format: AVPixelFormat, ) -> Result<Self, FfmpegError>

Creates a new Scaler instance.

Source

pub const fn pixel_format(&self) -> AVPixelFormat

Returns the pixel format of the scalar.

Source

pub const fn width(&self) -> i32

Returns the width of the scalar.

Source

pub const fn height(&self) -> i32

Returns the height of the scalar.

Source

pub fn process<'a>( &'a mut self, frame: &VideoFrame, ) -> Result<&'a VideoFrame, FfmpegError>

Processes a frame through the scalar.
