Struct gtk4::MediaStream

source ·
#[repr(transparent)]
pub struct MediaStream { /* private fields */ }
Expand description

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.
