  GES_PIPELINE_MODE_RENDER		= 1 << 2,
  GES_PIPELINE_MODE_SMART_RENDER = 1 << 3
} GESPipelineFlags;

The various modes the GESPipeline can be configured to.

GES_PIPELINE_MODE_PREVIEW_AUDIO

output audio to the soundcard

GES_PIPELINE_MODE_PREVIEW_VIDEO

output video to the screen

GES_PIPELINE_MODE_PREVIEW

output audio/video to soundcard/screen (default)

GES_PIPELINE_MODE_RENDER

render timeline (forces decoding)

GES_PIPELINE_MODE_SMART_RENDER

render timeline (tries to avoid decoding/reencoding)

enum GESEdge

typedef enum {
    GES_EDGE_START,
    GES_EDGE_END,
    GES_EDGE_NONE
} GESEdge;

The edges of an object contain in a GESTimeline or GESTrack

GES_EDGE_START

Represents the start of an object.

GES_EDGE_END

Represents the end of an object.

GES_EDGE_NONE

Represent the fact we are not workin with any edge of an object.

enum GESEditMode

typedef enum {
    GES_EDIT_MODE_NORMAL,
    GES_EDIT_MODE_RIPPLE,
    GES_EDIT_MODE_ROLL,
    GES_EDIT_MODE_TRIM,
    GES_EDIT_MODE_SLIDE
} GESEditMode;

You can also find more explanation about the behaviour of those modes at: trim, ripple and roll and clip management.

GES_EDIT_MODE_NORMAL

The object is edited the normal way (default).

GES_EDIT_MODE_RIPPLE

The objects are edited in ripple mode. The Ripple mode allows you to modify the beginning/end of a clip and move the neighbours accordingly. This will change the overall timeline duration. In the case of ripple end, the duration of the clip being rippled can't be superior to its max_duration - inpoint otherwise the action won't be executed.

GES_EDIT_MODE_ROLL

The object is edited in roll mode. The Roll mode allows you to modify the position of an editing point between two clips without modifying the inpoint of the first clip nor the out-point of the second clip. This will not change the overall timeline duration.

GES_EDIT_MODE_TRIM

The object is edited in trim mode. The Trim mode allows you to modify the in-point/duration of a clip without modifying its position in the timeline.

GES_EDIT_MODE_SLIDE

The object is edited in slide mode. The Slide mode allows you to modify the position of a clip in a timeline without modifying its duration or its in-point, but will modify the duration of the previous clip and in-point of the following clip so does not modify the overall timeline duration.

  GES_META_READABLE  = 1 << 0,
  GES_META_WRITABLE = 1 << 1,

} GESMetaFlag;

GES_META_READABLE

The metadata is readable

GES_META_WRITABLE

The metadata is writable

GES_META_READ_WRITE

The metadata is readable and writable
