<p>HI,</p>
<p>I got your point. Thanks for your information.</p>
<p>Is there any option to do normal file transfer(file with extensions like .jpeg, .txt) in live555?</p>
<p> </p>
<p>Thanks</p>
<p>Karthick.K</p>

<div>I think Ross may have missed the bit about different subnets.<br><br></div>I noticed your email indicates you work at Samsung. I work at Exacq Technologies and have done alot with Samsung cameras and we use live555. My usual contact at Samsung is <span title="byungjin.son@samsung.com" id="spnFrom">ByungJin Son [<a href="mailto:byungjin.son@samsung.com">byungjin.son@samsung.com</a>].<br><br></span></div><span title="byungjin.son@samsung.com" id="spnFrom">When there is more than one subnet, there is usually a router.<br><br></span></div><span title="byungjin.son@samsung.com" id="spnFrom">RTSP and live555 does</span><span title="byungjin.son@samsung.com" id="spnFrom"> Multicast or Unicast, but you still need a router. <br><br></span></div>
<div><span title="byungjin.son@samsung.com" id="spnFrom">If the two subnets are in the same machine, ie 2 NICs you can put the static routes there.<br><br></span></div>
<div><span title="byungjin.son@samsung.com" id="spnFrom">If "remote" means camera sits behind a firewall, then you need firewall rules to open ports to the outside world and probably NAT translation.<br><br></span></div>
<div><span title="byungjin.son@samsung.com" id="spnFrom">I have personally however, done a very similar thing Live555 does with the RTSP Register command. Google "RTSP Register"<br><br></span></div>
<div><span title="byungjin.son@samsung.com" id="spnFrom">Have the device (IP Camera?) reach out to a known server with the SDP packet. This starts a session thru a firewall. Just like how you can go to a website.<br><br></span></div>
<div><span title="byungjin.son@samsung.com" id="spnFrom">Then the remote server passes the socket to live555 and live555 can start the normal RTSP conversation right thru the firewall.<br><br></span></div>
<div><span title="byungjin.son@samsung.com" id="spnFrom">There are a few ways to do this, what exactly are you trying to do? Push video? Pull from behind a firewall? Ever heard of Sercomm, they have have an interesting protocol.<br></span></div>
