provided.<br>

I tried
both the
pipelines that

meta data has
not been

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

</div>
</div>
<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

is feed to the appsrc element.<br>
Following is the header that
is received<br>

Also not able to extract the

extract the metadata for the

Hi Stephan,<br>
<br>
Unfortunately I was not able to work on extracting audio metadata
from buffer from last 2 months.I started working on this again.<br>
<br>
Using curl, audio data is downloaded and using the following
pipeline(all three pipelines work), I am able to play the buffer
data. However not able to extract the streamtitle metadata. Other
metadata has been extracted like layer,mode,bitrate etc..<br>
<br>
app->pipeline= gst_parse_launch("appsrc name=mysource !
audio/mpeg ! mad ! alsasink", NULL);<br>
app->pipeline= gst_parse_launch("appsrc name=mysource !
audio/mpeg ! decodebin2 ! alsasink", NULL);<br>
app->pipeline= gst_parse_launch("appsrc name=mysource !
audio/mpeg ! mp3parse ! mad ! alsasink", NULL);<br>
<br>
I tried even setting "Accept-Charset:
ISO-8859-1,utf-8;q=0.7,*;q=0.7" in curl before sending http
request but still not able to extract the metadata.<br>
<br>
I somehow feel some prerequisites needs to be set in the curl
before sending http request for downloading buffer. It would be
really great to have your suggestions on this.<br>

If you run gst-launch -tv playbin2 uri=<a
class="moz-txt-link-freetext" href="http://208.186.112.40:8000/">http://208.186.112.40:8000/</a>
you will see which elements post the metadata in the above example.<br>
