Hey Frederic,<br>
<br>
Unless I'm missing something, you should be able to use decodebin as
such:<br>
<br>
your_source_element ! decodebin ! sink<br>
<br>
When your source element pushes "audio/x-raw" caps, decodebin will
simply<br>
pass through the buffers that follow. When it pushes non-raw caps,
decodebin<br>
will take care of selecting the appropriate parser / decoder.<br>
<br>
Does that answer your question?<br>

<div dir="ltr">Hi, I have a source audio element that can send PCM
or iec60958/61937. The src element update its output caps so the
downstream will know.
<div><br>
</div>
<div>An example case:</div>
<div>When src is PCM: PCM -> sink</div>
<div>When src is iec60958/: iec60958 -> parser -> audio
decoder -> PCM<br>
</div>
<div><br>
</div>
<div>Ideally would like this to be totally transparent to my top
level application that creates the pipeline. In other words I
don't want my top level app updating the pipeline.</div>
<div><br>
</div>
<div>Note the IEC60958/61937 I need to build also.<br>
</div>
<div><br>
</div>
<div>What would be the best options?</div>
<div>1-If I create the parser with proper pads/caps can
decodebin leverage it automatically?<br>
</div>
<div>2-Should I create a specific bin for my needs?</div>
<div><br>
</div>
<div>Any suggestions?<br>
