Latency and Passphrase

[vasudevavarun]

Hey,
I want to define "latency"and "passphrase" options in the outgoing connection.
Can you please tell me how can I do it!
Thanks.

@vasudevavarun you could specify them in URL. You could check specification here https://obsproject.com/wiki/Streaming-With-SRT-Protocol

The example of URL: srt://0.0.0.0.:9001?type=caller&latency=2000000.

About passphrase I'm not sure. @amukhsimov maybe you know more?

Hi @vasudevavarun. About passphrase, what you mean under "outgoing" connection? (I ask this question since the server now supports only pull mode)
But you can set passphrase for connecting/pushing to srt server by setting SRTO_PASSPHRASE option on the listener socket. See https://github.com/Haivision/srt/blob/master/docs/API/API-socket-options.md#SRTO_PASSPHRASE
Also you can checkout v0.3.0 branch, the code is more readable there.

I tried with

srt-server "srt://0.0.0.0:9008?latency=2000000&passphrase=test12345" "srt://0.0.0.0:9009?latency=2000000&passphrase=test12345"

srt-server 0.0.0.0:9008?passphrase=test12345678 0.0.0.0:9009?passphrase=test12345678

But it says operation not supported: Invalid socket ID or srt_listen: Operation not supported: Invalid socket ID

So I have tried to set a passprase on both listen port and send port

I can't make it work - but to get passprase solution I run another ffmpeg in listen with passprahse and with srt output to port 9008 but maybe a silly workaround but this is because I cant assign a passphrase.

But a very usefull if you need more than one OBS to get the stream from the server.

I solved the need for passphrase using /etc/systemd/system/securesrt.service
securesrt1.service
