Namespaces:

• GES

Interfaces:

• Extractable - A Object that implements the Extractable interface can be extracted from a Asset using extract.
• MetaContainer - A Object that implements MetaContainer can have metadata set on it, that is data that is unimportant to its function within GES, but may hold some useful information.

Classes:

• Asset - A Asset in the GStreamer Editing Services represents a resources that can be used.
• AudioSource - Children Properties
• AudioTestSource - Outputs a test audio stream using audiotestsrc.
• AudioTrack - A AudioTrack is a default audio Track, with a AUDIO track_type and "audio/x-raw(ANY)" caps.
• AudioTransition
• AudioUriSource - ### Children Properties
• BaseEffect - A BaseEffect is some operation that applies an effect to the data it receives.
• BaseEffectClip - BaseEffectClip-s are clips whose core elements are BaseEffect-s.
• BaseTransitionClip
• BaseXmlFormatter
• Clip - Clip-s are the core objects of a Layer.
• ClipAsset - The UriClipAsset is a special Asset specilized in Clip.
• CommandLineFormatter
• Container - A Container is a timeline element that controls other TimelineElement -s, which are its children.
• Effect - Any GStreamer filter can be used as effects in GES.
• EffectAsset - This asset has a GStreamer bin-description as ID and is able to determine to what track type the effect should be used in.
• EffectClip - The effect will be applied on the sources that have lower priorities (higher number) between the inpoint and the end of it.
• Formatter - Base class for timeline data serialization and deserialization.
• Group - A Group controls one or more Container-s (usually Clip -s, but it can also control other Group-s).
• ImageSource - Outputs the video stream from a given file as a still frame.
• Layer - Layer-s are responsible for collecting and ordering Clip-s.
• Marker - A timed MetaContainer object.
• MarkerList - A Marker can be colored by setting the META_MARKER_COLOR meta.

• Operation - Base class for overlays, transitions, and effects
• OperationClip - Operations are any kind of object that both outputs AND consumes data.
• OverlayClip - Overlays are objects which modify the underlying layer(s).
• Pipeline - A Pipeline can take an audio-video Timeline and conveniently link its Track-s to an internal playsink element, for preview/playback, and an internal encodebin element, for rendering.
• PitiviFormatter - This is a legacy format and you should avoid to use it.
• Project - The Project is used to control a set of Asset and is a Asset with `GES_TYPE_TIMELINE` as extractable_type itself.
• Source - Base class for single-media sources
• SourceClip - SourceClip-s are clips whose core elements are Source-s.
• SourceClipAsset - An asset types from which SourceClip will be extracted
• TestClip - Useful for testing purposes.
• TextOverlay
• TextOverlayClip - Renders text onto the next lower priority stream using textrender.
• Timeline - Timeline is the central object for any multimedia timeline.
• TimelineElement - A TimelineElement will have some temporal extent in its corresponding timeline, controlled by its start and duration.
• TitleClip - Renders the given text in the specified font, at specified position, and with the specified background pattern.
• TitleSource - TitleSource is a GESTimelineElement that implements the notion of titles in GES.
• Track - A Track acts an output source for a Timeline.
• TrackElement - A TrackElement is a TimelineElement that specifically belongs to a single Track of its timeline.
• TrackElementAsset
• Transition - Base class for media transitions.
• TransitionClip - Creates an object that mixes together the two underlying objects, A and B.
• UriClip - Represents all the output streams from a particular uri.
• UriClipAsset
• UriSource
• UriSourceAsset - Asset to create a stream specific Source for a media file.
• VideoSource - Base class for video sources
• VideoTestSource - ### Children Properties
• VideoTrack - A VideoTrack is a default video Track, with a VIDEO track_type and "video/x-raw(ANY)" caps.
• VideoTransition
• VideoUriSource - ### Children Properties
• XmlFormatter

Structs:

• FrameNumber - A datatype to hold a frame number.

Enums:

• AssetLoadingReturn
• ChildrenControlMode - To be used by subclasses only.
• Edge - The edges of an object contain in a Timeline or Track
• EditMode - When a single timeline element is edited within its timeline at some position, using edit, depending on the edit mode, its start, duration or in_point will be adjusted accordingly.
• Error
• MarkerFlags
• MetaFlag
• PipelineFlags - The various modes a Pipeline can be configured to.
• TextHAlign - Horizontal alignment of the text.
• TextVAlign - Vertical alignment of the text.
• TrackType - Types of content handled by a track.
• VideoStandardTransitionType
• VideoTestPattern - The test pattern to produce
