[Live-devel] Support required for Live555 Media Server

[Nambirajan]

Dear Mr. Ross Finlayson,

 

Thanks for your reply and suggestion.  

 

1.       We want to run two instances of Live555 Media Server in a system
simultaneously with two different IP addresses. Example one with 192.168.1.2
and other with 10.0.0.2. 

Is it possible and how can we achieve this?

2.       Can you please tell us whether running Live555 Media Sever on
different configuration systems will affect the number of RTSP streams it
can stream to multiple clients.

Example like 50 streams max on a Pentium Dual Core system and 100 streams
max in a Pentium Core 2 Duo system

3.       When running each instance in a client, the CPU utilization seems
to go up as follows. Approximately on a Pentium Core 2 Duo system serving 60
clients it takes 95%. CPU utilization ( Live555 Media Server )

It takes roughly 1.5% CPU utilization time per client. We are using OpenRTSP
as client running on different system. Is Live555 Media Server is CPU
intensive application?

 

Thanks and regards,

M. Nambirajan

1.      We have installed the Live555 Media Server on Red Hat Linux version
6.2 system. The Processor is Intel Pentium Dual core running at 2.6 GHz with
2GB DDR2 RAM

We run multiple instances of OpenRTSP client program / VLC player
application on 34 client systems and used the RTSP Server to stream to 34
clients. In this scenario

The CPU utilization of our Live555 RTSP Server has reached approximately 92%
for streaming. Beyond this, the RTSP stream in the first client system
starts to freeze and play

Is it true that each instance of streaming will take this much CPU
resources?

 

I suspect that you're hitting (or running close to hitting) an operating
system limit for the number of possible open sockets (see also
<http://www.live555.com/liveMedia/faq.html#scalability>).  You may wish to
increase this limit, if you can.

 





2.      Is it possible to run two instances of Live555 Media Server
application in the same Server simultaneously?

 

Yes, by having each instance use a different RTSP port number.

 





3.      Is it possible for us to make the Live555 Media Server to assign the
IP address of our wish. Example: There are two NIC ( Network Interface Card
)in the system,

onboard as well as PCI card based NIC. Is it possible to make the Live555
Media server to take the PCI based NIC IP Address instead of onboard NIC IP
Address.?

 

Yes.  The easiest way to ensure that one particular interface is chosen is
to make that interface the one for which multicast routing is enabled -
i.e., the interface that has a route for 224.0.0.0/4
