Recording a network audio stream

[Chris]

Hello Fred,

it has been quite for a while.
This is a preliminary question without working on a project yet.

I have a process running on a host that receives a UDP unicast/RTP/Opus encoded voice signal that is decoded to the earpeace of an ordinary telephone handset. ( http://www.pogo.org.uk/~mark/trx/ )
Now I am facing the need to record this UDP stream on the same host.

I read about uos_AddFromURL();  Is it possible to use an IP adress and a UDP port number with this function?
Example: uos_addFromURL('10.91.140.112:17000')  

The second question is about basic IP: Is it possible to receive the same socket (unicast) on the same host with two different processes? From my basic IP knowledge I would say NO.

My basic approach to this problem was to have the stream decoded to analogue , split it and re-encode it with UOS on a different sound card. It would require some additional circuitry on the analogue side and is perfectly feasible. But the direct approach would be more elegant.

Thanx in advance

Hello Chris.

For getting the url, uos uses  TFPHTTPClient.
In uos, it is in uos_httpgetthread.pas.

I have to study TFPHTTPClient to see how to deal with  use an IP adress and a UDP port number.

(Or maybe you know better TFPHTTPClient than me).

Once it is implemented for uos, it should not have problem for all your needs.

PS: For all internet stuff, I m not guru and have difficult access to internet.
But, trust me, we gonna find the solution of your project.
