Asynchronous state change

[Luis de Bethencourt]

Hello Alicia,

You can listen for messages in the pipeline's bus, and wait for the message
"GST_MESSAGE_STATE_CHANGED".

There is an example using it here:
http://docs.gstreamer.com/plugins/viewsource/viewpagesrc.action?pageId=327798

And some relevant reading material:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstPipeline.html
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/chapter-statemanage-states.html
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstMessage.html

Hope that helps :)
Luis
