* @short_description: A GstBin subclasses use to use GESTimeline
|
|
* as sources inside any GstPipeline.
|
|
* @see_also: #GESTimeline
|
|
*
|
|
* The gessrc is a bin that will simply expose the track src pads
|
|
* and implements the GstUriHandler interface using a custom `ges://`
|
|
* uri scheme.
|
|
*
|
|
* NOTE: That to use it inside playbin and friends you **need** to
|
|
* set gessrc::timeline property yourself.
|
|
*
|
|
* Example with #playbin:
|
|
*
|
|
* {{../../examples/c/gessrc.c}}
|
|
*
|
|
* Example with #GstPlayer:
|
|
