Struct MediaStream

pub struct MediaStream { /* private fields */ }

MediaStream is the integration point for media playback inside GTK.

GTK provides an implementation of the MediaStream interface that is called MediaFile.

Apart from application-facing API for stream playback, MediaStream has a number of APIs that are only useful for implementations and should not be used in applications: MediaStreamExt::prepared(), MediaStreamExt::unprepared(), MediaStreamExt::update(), MediaStreamExt::ended(), MediaStreamExt::seek_success(), MediaStreamExt::seek_failed(), MediaStreamExtManual::set_error(), Gtk::MediaStream::error(), Gtk::MediaStream::error_valist().

This is an Abstract Base Class, you cannot instantiate it.

Properties

duration

The stream’s duration in microseconds or 0 if unknown.

Readable

ended

Set when playback has finished.

Readable

error

None for a properly working stream or the GError that the stream is in.

Readable

has-audio

Whether the stream contains audio.

Readable

has-video

Whether the stream contains video.

Readable

loop

Try to restart the media from the beginning once it ended.

Readable | Writeable

muted

Whether the audio stream should be muted.

Readable | Writeable

playing

Whether the stream is currently playing.

Readable | Writeable

prepared

Whether the stream has finished initializing and existence of audio and video is known.

Readable | Writeable

seekable

Set unless the stream is known to not support seeking.

Readable

seeking

Set while a seek is in progress.

Readable

timestamp

The current presentation timestamp in microseconds.

Readable

volume

Volume of the audio stream.

Implements

MediaStreamExt, [trait@glib::ObjectExt], gdk::prelude::PaintableExt, MediaStreamExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl MediaStream

pub const NONE: Option<&'static MediaStream> = None

Trait Implementations

impl Clone for MediaStream

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 MediaStream

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

Formats the value using the given formatter.

impl HasParamSpec for MediaStream

type ParamSpec = ParamSpecObject

type SetValue = MediaStream

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for MediaStream

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<T: MediaStreamImpl> IsSubclassable<T> for MediaStream

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for MediaStream

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 MediaStream

type Parent = Object

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

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 MediaStream

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 MediaStream

fn static_type() -> Type

Returns the type identifier of Self.
