font-family:"Tahoma","sans-serif"'>Hi<br>
<br>
I am working with an axis camera which streams mpeg4 video.<br>
When I try to receive the video with live555, It works fine for about 60 sec,
and then the axis server sends a goodbye message. (the protocl is RTSP //
UDP/RTP)<br>
<br>
Then I tried it with their web interface (which uses rtsp too), and I can see a
RTCP packet every 10 sec called &quot;receiver report / source
description&quot; from my computer to the axis server. If I block this packet
with my firewall, the server stop sending video, so I assume this is required
to keep alive the connection.<br>
<br>
Why doesn't live555 sends this type of packet to keep the connection alive ? <br>
<br>
Thank you<br>
<br>
