Hi,
My goal is to 'live-stream' from my Debian Linux machines.
I want to use DSS for the streaming server and Mpeg4IP
on another machine as the network broadcast.
I'm not sure which list is most appropriate so please forgive
me if this is off-topic
One server for the video capture and Network broadcast.
One server for DSS so multiple clients can view live stream.
Server1: 192.168.3.110 - Mpeg4IP && bttv video capture
Server2: 192.168.3.10 - DSS ( Darwin Streaming Server + Internet )
Server1: Mpeg4IP is working 100% with video transmission set to: 192.168.3.10:45964
Server2: DSS has a copy of default.sdp file from Mpeg4IP in /usr/local/movies
I can 'tcpdump' on Server2:eth1 and see the UDP packets streaming in from Server1.
Example:
21:42:10.609603 IP 192.168.3.110.45964 > 192.168.3.10.45964: UDP, length: 1417
21:42:10.609653 IP 192.168.3.110.45964 > 192.168.3.10.45964: UDP, length: 172
21:42:10.688428 IP 192.168.3.110.45964 > 192.168.3.10.45964: UDP, length: 59
mp4player and the default.sdp transmission work fine, I can test Ok with this:
mp4player /usr/local/movies/default.sdp ( network transmission works 100% )
My problem is accessing the transmission via DSS.
This causes errors:

The mp4player hangs for a moment
at the 'url=rtsp://192.168.3.10/my_stream.sdp/trackID=1' line.
At this point my DSS server is still pretty much un-configured.
The test movies work fine.
So I can see the Mpeg4IP transmission is OK and the DSS
server streams the test mp4's well.
I've come alot closer by *not* having Mpeg4IP and DSS on the same box.
I must not be configuring something correctly, can you help?
My thinking is this type of transmission is not a 'relay' and I've
not configured any DSS 'relay' info.
I understand DSS can relay from broadcast to another streaming server.
Am I on the wrong track?
Any advice much appreciated.
Example default.sdp file:
v=0
o=- 1132484460641824 1132484460641824 IN IP4 192.168.3.10
s=default
i=
e=NONE
b=RR:0
t=0 0
m=video 45964 RTP/AVP 31
c=IN IP4 192.168.3.10
b=AS:500
Many thanks.
Regards,
Rudi.
