Rendezvous mode works only with outgoing connection

[IgorEsaul]

Socket socket = new Socket();
socket.setSockFlag(SockOpt.TRANSTYPE, Transtype.LIVE);
socket.setSockFlag(SockOpt.PAYLOADSIZE, 1316);
socket.rendezVous("0.0.0.0", remotehost, 5000);

if I set remotehost a non existent ip, connection is not established
Caller and Listener modes work fine.
I use android apps Larix Player, Haivision Play, Haivision Play Pro
Thank you.

Hi,

Do you have something on your logcat? Any hint about the issue?

As a temporary workaround, according to SRT documentation (https://github.com/Haivision/srt/blob/master/docs/API/API-functions.md#srt_rendezvous), rendezVous is a shortcut for doing bind locally, setting the SRTO_RENDEZVOUS option to true, and doing srt_connect..

It might be time to add an AndroidTest on rendezVous() to check what it's happening.

Regards,

socket.setSockFlag(SockOpt.RENDEZVOUS, true);
before rendezVous no success

logcat after 30 seconds of calling rendezVous
java.net.SocketException: Connection setup failure: connection timed out
at com.github.thibaultbee.srtdroid.models.Socket.rendezVous(Socket.kt:286)
at com.github.thibaultbee.srtdroid.models.Socket.rendezVous(Socket.kt:299)

i tried using "0.0.0.0", "localhost", "192.168.1.244" as the localhost value, no result
but
socket.bind(localhost, port);
socket.listen(10);
Pair<Socket, InetSocketAddress> pair = socket.accept();
it works well

I do not understand this phrase, rendezVous blocks the thread on 30 sec.

What operations do you perform on the peer device? I am not familiar with rendezVous API but the peer device should also call rendezVous.

I think it means that:

socket.rendezVous("0.0.0.0", remotehost, 5000);

is the equivalent of:

socket.bind("0.0.0.0", 5000)
socket.setSockFlag(SockOpt.RENDEZVOUS, true)
socket.connect(remotehost, 5000).

I use android apps Larix Player, Haivision Play, Haivision Play Pro on another device as peers
all these apps in the Rendezvous mode accept only incoming connections.
I tried ffplay Rendezvous mode does not work at all.

socket.bind("0.0.0.0", 5000)
socket.setSockFlag(SockOpt.RENDEZVOUS, true)
socket.connect(remotehost, 5000).
it works(if remotehost is valid), but
socket.bind("0.0.0.0", 5000);
socket.setSockFlag(SockOpt.RENDEZVOUS, true);
socket.listen(10);
socket.accept();
java.net.SocketException: Operation not supported: Listen/accept is not supported in rendezous connection setup

[IgorEsaul]

In the link Larix Player - Larix Brodcaster if an incorrect ip address is specified in one of the apps, the connection is not established, a similar situation srtdroid - srtdroid.
conclusion: rendezVous accepts incoming connections only from remotehost addresses, I think this is not right, the address of the incoming connection can be different from the destination address of the outgoing connection.
Thanks

Hi,

I am not sure I fully understand the issue. It seems to me that you are describing the server/listener mode instead of the rendezvous mode.
Anyway, for SRT issue, you may want to contact them directly.
