Struct gstreamer_editing_services::AudioTrack
source · pub struct AudioTrack { /* private fields */ }Expand description
A AudioTrack is a default audio Track, with a
TrackType::AUDIO track-type and “audio/x-raw(ANY)”
caps.
By default, an audio track will have its restriction-caps
set to “audio/x-raw” with the following properties:
- format: “S32LE”
- channels: 2
- rate: 44100
- layout: “interleaved”
These fields are needed for negotiation purposes, but you can change
their values if you wish. It is advised that you do so using
GESTrackExt::update_restriction_caps() with new values for the fields you
wish to change, and any additional fields you may want to add. Unlike
using GESTrackExt::set_restriction_caps(), this will ensure that these
default fields will at least have some value set.
§Implements
GESTrackExt, [trait@gst::prelude::BinExt], gst::prelude::ElementExt, gst::prelude::GstObjectExt, [trait@glib::ObjectExt], gst::prelude::ChildProxyExt, MetaContainerExt
GLib type: GObject with reference counted clone semantics.
Implementations§
source§impl AudioTrack
impl AudioTrack
pub const NONE: Option<&'static AudioTrack> = None
sourcepub fn new() -> AudioTrack
pub fn new() -> AudioTrack
Creates a new audio track, with a TrackType::AUDIO
track-type, “audio/x-raw(ANY)” caps, and
“audio/x-raw” restriction-caps with the properties:
- format: “S32LE”
- channels: 2
- rate: 44100
- layout: “interleaved”
You should use GESTrackExt::update_restriction_caps() if you wish to
modify these fields, or add additional ones.
§Returns
The newly created audio track.

fn request_pad_simple(&self, name: &str) -> Option<Pad>
The name of this function is confusing to people learning GStreamer.
request_pad_simple() aims at making it more explicit it is
a simplified ElementExt::request_pad(). Read moresource§fn link(&self, dest: &impl IsA<Element>) -> Result<(), BoolError>

Links
self to dest. The link must be from source to
destination; the other direction will not be tried. The function looks for
existing pads that aren’t linked yet. It will request new pads if necessary.
Such pads need to be released manually when unlinking.

Updates the

compared against the existing structure with the same index in the
current restriction-caps. If there is no corresponding
existing structure at that index, then the new structure is simply

fn find_unlinked_pad(&self, direction: PadDirection) -> Option<Pad>
Recursively looks for elements with an unlinked pad of the given

if one is found, or
None otherwise. If a pad is found, the caller
owns a reference to it and should use gst_object_unref() on the

You can cast this element to the given interface afterwards. If you want

fn remove(&self, element: &impl IsA<Element>) -> Result<(), BoolError>
Removes the element from the bin, unparenting it as well.
Unparenting the element means that the element will be dereferenced,
so if the bin holds the only reference to the element, the element
will be freed in the process of removing it from the bin. If you
want the element to still exist after removing, you need to call
gst_object_ref() before removing it from the bin. Read moresource§fn set_suppressed_flags(&self, flags: ElementFlags)

not be propagated to the bin. Read moresource§fn sync_children_states(&self) -> Result<(), BoolError>
