<DIV><FONT face=Verdana size=2>Hi, Everyone</FONT></DIV>
<DIV> </DIV>
<DIV>I have met such a situation. I have to manage a pipeline manually to
playback OGG files.</DIV>
<DIV>As you know, an ogg file may be either pure audio or mixed with audio and
video.</DIV>
<DIV>If I put all possible elements (the filesrc, demuxer, audioqueue,
videoqueue, decoder ... etc.) into the pipeline, the pipeline seems not to work
when the file contains audio only, and it works if the file contains both audio
and video.</DIV>
<DIV> </DIV>
<DIV>So what may the problem be?</DIV>
<DIV> </DIV>
<DIV>Can anyone explain what may happen if the pipeline contains elements that
are not needed.</DIV>
<DIV> </DIV>
<DIV>filesrc --> demuxer --> audioqueue --> ... --> audiosink </DIV>
<DIV> </DIV>
<DIV>
videoquque --> ... --> videosink (here, the videoqueue and the
related elements are not used)</DIV>
<DIV> </DIV>
<DIV>I wish I have described the problem clearly.</DIV>
<DIV> </DIV>
<DIV>Best regards.</DIV>
