|
* @short_description: Base Class for sources of a #GESLayer
|
|
*
|
|
* #GESSourceClip-s are clips whose core elements are #GESSource-s.
|
|
*
|
|
* ## Effects
|
|
*
|
|
* #GESSourceClip-s can also have #GESBaseEffect-s added as non-core
|
|
* elements. These effects are applied to the core sources of the clip
|
|
* that they share a #GESTrack with. See #GESClip for how to add and move
|
|
* these effects from the clip.
