parent

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit notify and deep-notify signals due to locking issues. In some cases one can use GstBin::element-added or GstBin::element-removed signals on the parent to achieve a similar effect.

Implements

gst::prelude::ObjectExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl GLViewConvert

pub fn new() -> GLViewConvert

Returns

a new GLViewConvert

pub fn perform(&self, inbuf: &Buffer) -> Option<Buffer>

Converts the data contained by inbuf using the formats specified by the gst::Caps passed to set_caps()

inbuf

the GLMemory filled gst::Buffer to convert

Returns

a converted gst::Buffer or None

pub fn reset(&self)

Reset self to the default state. Further operation will require setting the caps with set_caps().

pub fn set_caps(&self, in_caps: &Caps, out_caps: &Caps) -> Result<(), BoolError>

Initializes self with the information required for conversion.

in_caps

input gst::Caps

out_caps

output gst::Caps

pub fn set_context(&self, context: &impl IsA<GLContext>)

Set context on self

context

the GLContext to set

pub fn transform_caps( &self, direction: PadDirection, caps: &Caps, filter: &Caps, ) -> Caps

Provides an implementation of GstBaseTransformClass.transform_caps()

direction

a gst::PadDirection

caps

the gst::Caps to transform

filter

a set of filter gst::Caps

Returns

the converted gst::Caps

pub fn downmix_mode(&self) -> GLStereoDownmix

pub fn set_downmix_mode(&self, downmix_mode: GLStereoDownmix)

Trait Implementations

impl Clone for GLViewConvert

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for GLViewConvert

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

Formats the value using the given formatter.

impl Default for GLViewConvert

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for GLViewConvert

type ParamSpec = ParamSpecObject

type SetValue = GLViewConvert

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, GLViewConvert>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GLViewConvert

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

where H: Hasher,

Hashes the memory address of this object.

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 GLViewConvert

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 ParentClassIs for GLViewConvert

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for GLViewConvert

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for GLViewConvert

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 StaticType for GLViewConvert

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for GLViewConvert

impl IsA<Object> for GLViewConvert

impl Send for GLViewConvert

impl Sync for GLViewConvert
