Struct SampleAspectRatio 

pub struct SampleAspectRatio {
    pub num: u32,
    pub den: u32,
}

Reduced pixel-width to pixel-height ratio.

Fields

num: u32

Ratio numerator.

den: u32

Ratio denominator, never zero.

Implementations

impl SampleAspectRatio

pub fn new(num: u64, den: u64) -> Option<Self>

The ratio num:den in lowest terms, or None when either term is zero (FFmpeg writes an unknown ratio as 0/1).

pub fn of_display(visible: (u32, u32), displayed: (u32, u32)) -> Option<Self>

The pixel aspect ratio of a visible picture shown at displayed size, as a WebCodecs display size gives it.

Display sizes are rounded to whole pixels (128x96 at 4:3 shows 171x96, not 170 2/3), so this returns the simplest fraction that rounds to that size. That recovers small declared ratios such as 4:3, 64:45 and 10:11 exactly.

pub fn square_pixel_size(self, width: u32, height: u32) -> (u32, u32)

The square-pixel display size of a stored width x height picture: the longer pixel side stretched, rounded half up, as browser demuxers report it.
