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.
