fn add_encoding_profile(
&self,
profile: &impl IsA<EncodingProfile>
) -> Result<(), BoolError>
fn add_encoding_profile(
&self,
profile: &impl IsA<EncodingProfile>
) -> Result<(), BoolError>
Adds profile
to the project. It lets you save in what format
the project has been renders and keep a reference to those formats.
Also, those formats will be saves to the project file when possible.
profile
A gst_pbutils::EncodingProfile
to add to the project. If a profile with
the same name already exists, it will be replaced
Returns
fn add_formatter(&self, formatter: &impl IsA<Formatter>)
fn add_formatter(&self, formatter: &impl IsA<Formatter>)
v1_18
only.Create and add a Asset
to self
. You should connect to the
“asset-added” signal to get the asset when it finally gets added to
self
id
The id of the asset to create and add to self
extractable_type
The GType
of the asset to create
Returns
true
if the asset started to be added false
it was already
in the project
id
The id of the asset to retrieve
extractable_type
The extractable_type of the asset
to retrieve from object
Returns
Get the assets that are being loaded
Returns
A set of loading asset
that will be added to self
. Note that those Asset are not loaded yet,
and thus can not be used
fn list_encoding_profiles(&self) -> Vec<EncodingProfile>ⓘ
fn list_encoding_profiles(&self) -> Vec<EncodingProfile>ⓘ
Lists the encoding profile that have been set to self
. The first one
is the latest added.
Returns
The
list of gst_pbutils::EncodingProfile
used in self
Save the timeline of self
to uri
. You should make sure that timeline
is one of the timelines that have been extracted from self
(using ges_asset_extract (self
);)
timeline
The Timeline
to save, it must have been extracted from self
uri
The uri where to save self
and timeline
formatter_asset
The formatter asset to
use or None
. If None
, will try to save in the same format as the one
from which the timeline as been loaded or default to the best formatter
as defined in ges_find_formatter_for_uri
overwrite
true
to overwrite file if it exists
Returns

fn connect_error_loading_asset<F: Fn(&Self, &Error, &str, Type) + 'static>(
&self,
f: F
) -> SignalHandlerId
Informs you that a Asset
could not be created. In case of
missing GStreamer plugins, the error will be set to GST_CORE_ERROR
gst::CoreError::MissingPlugin
error
The glib::Error
defining the error that occured, might be None
id
The id
of the asset that failed loading
extractable_type
The extractable_type
of the asset that
failed loading

error
The error that happened
wrong_asset
The asset with the wrong ID, you should us it and its content only to find out what the new location is.
Returns
The new URI of wrong_asset
