Struct VideoModeOptions 

pub struct VideoModeOptions(/* private fields */);

Optional video mode parameters.

Implementations

impl VideoModeOptions

pub const fn new() -> VideoModeOptions

Create new empty set of options.

pub const fn set_quantization_level(&mut self, level: u8)

Set video codec quantization level.

Non-zero value makes video encoding lossy. Typical value is between 0 and 4.

pub const fn quantization_level(&self) -> u8

Returns video codec quantization level.

pub const fn set_chroma_subsampling(&mut self, value: bool)

Enables/disables 4:2:0 chroma subsampling.

Chroma subsampling makes video encoding lossy.

pub const fn chroma_subsampling(&self) -> bool

Returns true when chroma subsampling is enabled.

pub const fn set_raw(&mut self, value: bool)

Sets raw mode.

When enabled, video frames are written in the original format without encoding.

This is useful when running the code in a RISCV interpreter.

pub const fn raw(&self) -> bool

Returns true when raw mode is enabled.

pub const fn as_u64(self) -> u64

Trait Implementations

impl Clone for VideoModeOptions

fn clone(&self) -> VideoModeOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VideoModeOptions

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

Formats the value using the given formatter.

impl Default for VideoModeOptions

fn default() -> VideoModeOptions

Returns the “default value” for a type.

impl PartialEq for VideoModeOptions

fn eq(&self, other: &VideoModeOptions) -> 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<u64> for VideoModeOptions

type Error = ()

The type returned in the event of a conversion error.

fn try_from( other: u64, ) -> Result<VideoModeOptions, <VideoModeOptions as TryFrom<u64>>::Error>

Performs the conversion.
