GStreamer Editing Services
--------------------------

 This is a high-level library for facilitating the creation of audio/video
non-linear editors.


Dependencies:
-------------

 * GStreamer core
 * gst-plugins-base
 * gnonlin

Classes:
--------

<Public>
 TimelinePipeline : GstPipeline for Timeline playback/rendering
   => Add methods to save/load to/from files
   ?? Do we need undo/redo support ?
 Timeline : Top-level container (is also a GstBin)
   SimpleAVTimeline : Convenience A+V Timeline
 TimelineObject : Base-class for objects you can put in a TimelineLayer
   TimelineSource : Source objects to use in a TimelineLayer
     => _from_uri(const gchar *uri): automatically creates a TimelineSource
   TimelineTransition : Transitions
   (TimelineEffect)
 TimelineLayer : Layer of TimelineObject
   SimpleTimelineLayer : Simpler API (contiguous objects, list API)

<PRIVATE>
 Track : High-level single-media Composition (is a GstBin). Represents a 'stream'.
 TrackObject : Base-class for objects you can put in a Track
  TrackSource
  TrackOperation

Usage:
------

 Create a TimelinePipeline...

   pipeline = ges_timeline_pipeline_new();

 ... with one layer

   layer1 = ges_simple_timeline_layer_new();
   ges_timeline_pipeline_add_layer (layer1);

 Add a video source to the end

   src1 = ges_timeline_source_from_uri("/my/cool/file.avi");
   ges_simple_timeline_layer_add(src1, -1);

 Set video output XID and play back the timeline

   ges_timeline_pipeline_set_xid(1234567);
   ges_timeline_pipeline_play();

 Save Timeline to a file

   ges_timeline_save ("/my/project.ges");

 Stop output and render to a file

   ges_timeline_pipeline_stop();
   ges_timeline_pipeline_render_to_file("/my/output.mov", OUTPUT_SETTINGS);
