|
|
* GstPlay is a simple class for audio and video playback.
|
|
* It's job is to get the media (supplied by a URI) played.
|
|
* More specific it should get the media from source to the output elements.
|
|
* How that is done should not be relevant for developers using this class.
|
|
* A user using this class should not have to know very much about how
|
|
* GStreamer works, other than that it plays back media.
|
|
* Additionally it supplies signals to get information about the current
|
|
* playing state.
