Struct SourceBufferList 

pub struct SourceBufferList { /* private fields */ }

The Source Buffer List is a list of SourceBuffers that can be indexed numerically and monitored for changes. The list itself cannot be modified through this interface, though the Source Buffers it holds can be modified after retrieval.

It is used by MediaSource to provide direct access to its child SourceBuffers through source-buffers as well as informing clients which of the Source Buffers are active through active-source-buffers.

Properties

length

The number of SourceBuffers contained by this structure

Specification

Readable

Object

name

Readable | Writeable | Construct

parent

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit GObject::notify and [deep-notify][struct@crate::gst::Object#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.

Readable | Writeable

Signals

on-sourcebuffer-added

Emitted when a SourceBuffer has been added to this list.

Specification

on-sourcebuffer-removed

Emitted when a SourceBuffer has been removed from this list.

Specification

Object

deep-notify

The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.

Detailed

Implements

gst::prelude::ObjectExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl SourceBufferList

pub fn length(&self) -> u32

Specification

Returns

The number of SourceBuffer objects in the list

pub fn index(&self, index: u32) -> Option<SourceBuffer>

Retrieves the SourceBuffer at index from self. If index is greater than the highest index in the list, it will return NULL.

Specification

index

index of requested Source Buffer

Returns

The requested SourceBuffer or NULL

pub fn connect_on_sourcebuffer_added<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Emitted when a SourceBuffer has been added to this list.

Specification

pub fn connect_on_sourcebuffer_removed<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Emitted when a SourceBuffer has been removed from this list.

Specification

pub fn connect_length_notify<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Trait Implementations

impl Clone for SourceBufferList

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 SourceBufferList

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

Formats the value using the given formatter.

impl HasParamSpec for SourceBufferList

type ParamSpec = ParamSpecObject

type SetValue = SourceBufferList

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SourceBufferList

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 SourceBufferList

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,

Restrict a value to a certain interval.

impl ParentClassIs for SourceBufferList

type Parent = Object

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

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

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

impl<OT: ObjectType> PartialOrd<OT> for SourceBufferList

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for SourceBufferList

fn static_type() -> Type

Returns the type identifier of Self.
