Struct gstreamer_video::VideoVBIParser

pub struct VideoVBIParser { /* private fields */ }

A parser for detecting and extracting VideoAncillary data from Vertical Blanking Interval lines of component signals.

Implementations

impl VideoVBIParser

pub fn try_new( format: VideoFormat, pixel_width: u32 ) -> Result<VideoVBIParser, VideoVBIError>

pub fn line_buffer_len(&self) -> usize

Returns the buffer length needed to store the line.

pub fn add_line(&mut self, data: &[u8]) -> Result<(), VideoVBIError>

Provide a new line of data to the self. Call [ancillary()][Self::ancillary()] to get the Ancillary data that might be present on that line.

data

The line of data to parse

pub fn iter(&mut self) -> AncillaryIter<'_>

pub fn next_ancillary( &mut self ) -> Option<Result<VideoAncillary, VideoVBIError>>

Trait Implementations

impl Debug for VideoVBIParser

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

Formats the value using the given formatter.

impl Hash for VideoVBIParser

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 Ord for VideoVBIParser

fn cmp(&self, other: &VideoVBIParser) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for VideoVBIParser

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for VideoVBIParser

fn partial_cmp(&self, other: &VideoVBIParser) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> TryFrom<&'a VideoInfo> for VideoVBIParser

type Error = VideoVBIError

The type returned in the event of a conversion error.

fn try_from(info: &'a VideoInfo) -> Result<VideoVBIParser, VideoVBIError>

Performs the conversion.
