Struct gstreamer_editing_services::Project

pub struct Project(_, _);

The Project is used to control a set of Asset and is a Asset with GES_TYPE_TIMELINE as extractable_type itself. That means that you can extract Timeline from a project as followed:

 GESProject *project;
 GESTimeline *timeline;

 project = ges_project_new ("file:///path/to/a/valid/project/uri");

 // Here you can connect to the various signal to get more infos about
 // what is happening and recover from errors if possible
 ...

 timeline = ges_asset_extract (GES_ASSET (project));

The Project class offers a higher level API to handle Asset-s. It lets you request new asset, and it informs you about new assets through a set of signals. Also it handles problem such as missing files/missing gst::Element and lets you try to recover from those.

Subprojects

In order to add a subproject, the only thing to do is to add the subproject to the main project:

ges_project_add_asset (project, GES_ASSET (subproject));

then the subproject will be serialized in the project files. To use the subproject in a timeline, you should use a UriClip with the same subproject URI.

When loading a project with subproject, subprojects URIs will be temporary writable local files. If you want to edit the subproject timeline, you should retrieve the subproject from the parent project asset list and extract the timeline with AssetExt::extract and save it at the same temporary location.

Implementations

impl Project

pub fn new(uri: Option<&str>) -> Project

Creates a new Project and sets its uri to uri if provided. Note that if uri is not valid or None, the uri of the project will then be set the first time you save the project. If you then save the project to other locations, it will never be updated again and the first valid URI is the URI it will keep refering to.

uri

The uri to be set after creating the project.

Returns

A newly created Project
