Required methods
fn add_asset<P: IsA<Asset>>(&self, asset: &P) -> bool
Adds a Asset
to self
, the project will keep a reference on
asset
.
asset
A Asset
to add to self
Returns
true
if the asset could be added false
it was already
in the project
fn add_encoding_profile<P: IsA<EncodingProfile>>(
&self,
profile: &P
) -> Result<(), BoolError>
&self,
profile: &P
) -> 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
true
if profile
could be added, false

fn create_asset(&self, id: Option<&str>, extractable_type: Type) -> bool
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 glib::Type
of the asset to create
Returns
true
if the asset started to be added false
it was already
in the project
fn create_asset_sync(
&self,
id: Option<&str>,
extractable_type: Type
) -> Result<Option<Asset>, Error>
&self,
id: Option<&str>,
extractable_type: Type
) -> Result<Option<Asset>, Error>
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 glib::Type
of the asset to create
Returns
The newly created Asset
or None
.
fn get_asset(&self, id: &str, extractable_type: Type) -> Option<Asset>
id
The id of the asset to retrieve
extractable_type
The extractable_type of the asset
to retrieve from object
Returns
The Asset
with
id
or None
if no asset with id
as an ID
fn get_loading_assets(&self) -> Vec<Asset>
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 get_uri(&self) -> Option<GString>
fn list_assets(&self, filter: Type) -> Vec<Asset>
List all asset
contained in self
filtering per extractable_type
as defined by filter
. It copies the asset and thus will not be updated
in time.
filter
Type of assets to list, GES_TYPE_EXTRACTABLE
will list
all assets
Returns
The list of
Asset
the object contains
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
fn load<P: IsA<Timeline>>(&self, timeline: &P) -> Result<(), Error>
Loads self
into timeline
timeline
A blank timeline to load self
into
Returns
true
if the project could be loaded false
otherwize.
fn remove_asset<P: IsA<Asset>>(&self, asset: &P) -> Result<(), BoolError>
remove a asset
to from self
.
asset
A Asset
to remove from self
Returns
true
if the asset could be removed false
otherwise
fn save<P: IsA<Timeline>, Q: IsA<Asset>>(
&self,
timeline: &P,
uri: &str,
formatter_asset: Option<&Q>,
overwrite: bool
) -> Result<(), Error>
&self,
timeline: &P,
uri: &str,
formatter_asset: Option<&Q>,
overwrite: bool
) -> Result<(), Error>
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
true
if the project could be save, false
