Re: Help with Reflector DSS?



What you're hitting is an assert in the server, and its then tearing down/disconnecting the QuickTime client (thus the -3285 error message). An assert, in programming terms, is simply a comparison statement in the code that a certain condition is expected to be true (or within a certain boundary). For some reason, your DSS 4.1.2 Win2K machine happens to be failing a very specific assumption in the code, and thus the assert is false and logged. I don't believe I've not seen this particular assert before, so there is something interesting going on with your particular configuration.

By any chance, are you running on a dual processor Win2K Intel machine? If so, then let me suggest that you download the latest Darwin Streaming Server 4.1.3 for Windows and install it, and see if the problem persists.

Hi all,

I am not sure if I have to use the DSS like "reflector" feature, but I have not been able to get it too, well, I think it will be better if I explain it to you:

I have installed Darwin Streaming Server 4.1.2 on Win2K SP3 server machine.

My "broadcaster" is a Tandberg videoconference equipment with the streaming feature, it streams H.261 video and u-law audio. it works well with QT6 when I receive the multicast or unicast streaming directly from the videoconference codec to my PC with W98 in my Lan segment, but I want to transmit a live streaming signal through the intranet, that is I want to use the DSS.

The setup DSS test works well, but I have not been able to transmit a live webcast throught DSS.

I put this SDP file in the "movies" folder in the DSS4 server, it made itself in my videoconference equipment:

v=0
o=SYM 1 96 1 IN IP4 13.49.190.207
s=TANDBERG Streaming
i=A streaming session from TANDBERG codec
c=IN IP4 224.2.41.169/15
m=video 22232 RTP/AVP 31
a=recvonly
m=audio 22236 RTP/AVP 0
a=recvonly

Then, when I want to get it with QT6: rtsp://myDSSserver/stream.sdp (with and without *.sdp), the player displays the error: "-3285 disconnected" and the DSS system break down suddenly, all the web-based DSS Admin UI displays "Unknown error: disconnected" and then I have to reset the application because it does not response.

The error log writes:
...

... all the time I want to try to connect it.


I have tried to change the port to HTTP: 80 in the DSSserver, then I used the request player: http://myDSSserver/stream.sdp with the change of the streaming transport ports in the player and the result is "connecting".... "connecting"... and nothing else !

Also, I tried change the ip multicast address for the myDSSserver ip address into the SDP file and add the relay configuration in the DSS and it did not happen nothing !

Then, I have three cuestions:

1. There is a question for how does the reflector work in the Streaming Server FAQs in QT Apple web page so, do I have to install and compile the ReflectorModules?. If it is true, can I use the source code in Windows 2000?, could anybody help me please...?, because I am new with this !!.

2. Do I need to install the cygwin? You are not mention it in your instructions for install it.

3. Neither one previous, so What do I have to do ?...

Please help me, I am lost !

I thank you in advance for your help.


Regards.
