[Live-devel] rtsp and keeping alive connection with rtcp packets

[Anthony Champagne]

Hi, 

 

I’ve experienced the same problem with RTP/UDP.

My problem is that the live555 library takes IP address of the RTCP packet
destination in the SDP description (RTSP proto).

My camera doesn’t give this address in the c= field (if I remember well), it
fills it with 0.0.0.0, so the library send RTCP packet to 0.0.0.0 and it
doesn’t work.

There’s a method to force RTCP packet destination otherwise.

To solve the problem I’m using RTP over TCP and it doesn’t need RTCP packets
anymore.

 

Regards,

 

Anthony Champagne

Hi

I am working with an axis camera which streams mpeg4 video.
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)

Then I tried it with their web interface (which uses rtsp too), and I can
see a RTCP packet every 10 sec called "receiver report / source description"
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.

Why doesn't live555 sends this type of packet to keep the connection alive ?


Thank you
