<div> Hi stephan,<br>
<br>
First would like to
thank you for the input
you provided.<br>
<br>
I tried both the
pipelines that you have
mentioned,however meta
data has not been
extracted.<br>
<br>
Kindly request you to
let me know if there are
any other changes that
needs to be done.<br>

Are you sure the stream you are
looking at is tagged with such
metadata? Try gst-launch-0.10 -t
playbin2 uri=...<span><font color="#888888"><br>

<div><br>
Yes the stream contains the metadata like
streamTitle, streamUrl. In order to check
does the stream really has metadata, appsrc
buffer is written to a file and checked
using hexedit and I can find the
metadata.Sure will try your suggestion
tomorrow and update you. Thankyou. <br>

Hi Stephan,<br>
<br>
gst-launch-0.10 -t playbin2 uri=.... is also not
extracting the metadata.<br>
<br>
Actually I am streaming the shoutcast
stream.Audio stream data is feed to the appsrc
element.<br>
Following is the header that is received<br>
<br>
ICY 200 OK^M<br>
icy-notice1:<BR>This stream requires <a

icy-br:128^M<br>
<br>
Metadata is available as "StreamTitle='Aditi Singh

However I am not able to extract the same.<br>
<br>
Also not able to extract the metadata for the
downloaded mp3 file using the following pipelines.
However the above command that you mentioned will
extract the metadata for the downloaded mp3 file
<div><br>
<br>
appsrc name=mysource ! audio/mpeg ! mad ! alsasink<br>
</div>
<div>
appsrc name=mysource ! audio/mpeg ! mp3parse ! mad

</div>
<div>appsrc name=mysource ! audio/mpeg !

Your input would be of great help.<br>
