Hi I a beginner with GStreamer, I am clueless about of the behavior and role of some GStreamer elements.<br>I wrote a pipeline to get transition effect between 2 avi videos, it works fine but the sond, there's no sound at all.<br>
I was told to put an avidemuxer, I've been working around with it without luck. <br><br>I put it between the queue and the gnlcomposition,it doesn't work, then I put after the queue. I wonder if some decoder is missing.<br>
<br>I tryed to adapt my pipeline to this one: <a href="http://lists.freedesktop.org/archives/gstreamer-devel/2008-October/019240.html" target="_blank">http://lists.freedesktop.org/archives/gstreamer-devel/2008-October/019240.html</a>, but any adaptation didn't work for me.<br>
<br>I got many kind of errors:<br>"GStreamer-CRITICAL **: gst_pad_link_full: assertion `GST_IS_PAD (sinkpad)' failed"<br>or<br>Segment Violation<br><br>Thanks a lot, <br><br>Rossana<br><br>This is the pipeline I need to adapt to hear the sound:<br>
