As for the delay, VLC typically has a 300ms to 1sec delay but it
depends on your version. To change it, when you go to Open
Media/Network, select the Show More Options box and reduce caching
to a smaller number.<br>
<br>
I think we should refrain from VLC talk lest the Gstreamer gods
strike down this thread for our blasphemy ;) Post this over in the
Gforge forums and you'll get a bit more general support there as
well.<br>

<div>Yes it is working over network on VLC player now. Though
there is a delay. Any answers to that? Kartik do you have any
delay in your video. How did you fix it?</div>
<div><br>
</div>
<div>Also, since it is working on VLC now over network. Thats not
my final aim. What I am looking at is to capture the buffer,
decode it and pass the frames across to another application.
Any idea as to how will I capture the incoming RTP buffer on
windows?</div>

just copy/pasted your sprop-parameter-sets

Gstreamer formating and escape characters for
it to work, ie.

You might want to ask this on the
gstreamer TI forums as well since you're
using, I'm assuming, an TI SoC. A while
back, I know for the Davinci H.264
encoders the SPS was sent only once at
the begin of the encode, so any clients
that connected later just missed out and
wouldn't connect without a good sdp
file. I believe with some tweaking the
encoder can be forced to send it out
periodically so you wouldn't have to
define it in your sdp file. Post your
question there as well. It's at <a
