<div>Hello Alicia,<br>
<br>
</div>
You can listen for messages in the
pipeline's bus, and wait for the message
"GST_MESSAGE_STATE_CHANGED".<br>
<br>
</div>
There is an example using it here:<br>
<a moz-do-not-send="true"
href="http://docs.gstreamer.com/plugins/viewsource/viewpagesrc.action?pageId=327798"
target="_blank">http://docs.gstreamer.com/plugins/viewsource/viewpagesrc.action?pageId=327798</a><br>
<br>

<div>Hi List,<br>
</div>
I want to change the state of a
pipeline and wait till the
pipeline has the wanted state. <br>

Is there a way to know when the
pipeline has change to the state
we set before?<br>

Thank!!<br>
