Struct gstreamer_editing_services::VideoTrack
source · pub struct VideoTrack { /* private fields */ }
Expand description
A VideoTrack
is a default video Track
, with a
TrackType::VIDEO
track-type
and “video/x-raw(ANY)”
caps
.
By default, a video track will have its restriction-caps
set to “video/x-raw” with the following properties:
- width: 1280
- height: 720
- framerate: 30/1
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 VideoTrack
impl VideoTrack
pub const NONE: Option<&'static VideoTrack> = None
sourcepub fn new() -> VideoTrack
pub fn new() -> VideoTrack
Creates a new video track, with a TrackType::VIDEO
track-type
and “video/x-raw(ANY)” caps
, and
“video/x-raw” restriction-caps
with the properties:
- width: 1280
- height: 720
- framerate: 30/1
You should use GESTrackExt::update_restriction_caps()
if you wish to
modify these fields, or add additional ones.
§Returns
The newly created video track.
