your problem.<br><br>The problem is that wavparse's sink pad is a sometimes pad which will be<br>added only later when data flow starts (-> 'dynamic pads'). The reason<br>for that is that wavparse needs to figure out the type of data first (it<br>
uses dynamic pads for historical reason related to decodebin/playbin, it<br>doesn't strictly have to, but we can't change that now). So there will<br>be no sink pad to link to after the element has been created, and you<br>
will need to do the linking to audioconvert or whatever in a pad-added<br>callback later.<br><br>Mad's sink pad on the other hand always exists, so you can link it right<br>away.<br><br>Still, I would recommend you just use uridecodebin/decodebin2/playbin2<br>
if that's an option.<br>
