Enum Format 

#[repr(u32)]
pub enum Format {
    H264 = 1_211_250_228,
    YUYV = 1_498_765_654,
    YV12 = 1_498_820_914,
    RGB3 = 1_380_401_715,

}

The fourCC code to capture in.

Currently supported formats are H264 and those supported by libx264.

Variants

H264 = 1_211_250_228

H264 format. Selecting this option will disable software encoding, which is generally much faster but can reduce quality or compression ratio.

YUYV = 1_498_765_654

YUYV format. In this format, 4 bytes encode 2 pixels, with the first encoding the Y or luminance component for the first pixel, the second encoding the U or Cb component for both pixels, the third encoding the Y component for the second pixel, and the fourth encoding the V or Cr component for both pixels.

YV12 = 1_498_820_914

YV12 format. 6 bytes encode 4 pixels, with the first 4 bytes encoding the Y component for each pixel, the fith byte encoding the V component for all 4 pixels, and the last byte encoding the U component for all 4 pixels. The “12” refers to the format’s bit depth.

RGB3 = 1_380_401_715

RGB format. 3 bytes encode 1 pixel, with the first encoding the red component, the second encoding the green component, and the third encoding the blue component.

BGR3 = 1_111_970_355

BGR format. 3 bytes encode 1 pixel, with the first encoding the blue component, the second encoding the green component, and the third encoding the red component.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Format

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

Formats the value using the given formatter.

impl Display for Format

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

Formats the value using the given formatter.

impl From<Format> for [u8; 4]

fn from(format: Format) -> Self

Converts to this type from the input type.

impl Hash for Format

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Format

fn eq(&self, other: &Format) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<[u8; 4]> for Format

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: [u8; 4]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u32> for Format

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Format

impl Eq for Format

impl StructuralPartialEq for Format
