Keep Alive method - RTSP

[AdiAbuAli]

Hi,
Am using synology surveillance, with Wyze bridge over RTSP/TCP....
For keep alive, there are 3 options in synology:
Disable
Options (Default)
GET_Parameters

I choosed get_parameters (fixed each 5s) based on the out of Describe command response from server...

Is this right?...can I disable it?

You can either use OPTIONS or GET_PARAMETERS, the server accepts both and periodically checks the timing of the last keepalive request.

Ok...From server side, the keep alive timer correspomf to RTSP ReadTimeOut setting?

I checked, and the server keepalive is currently hardcoded at 60 seconds:

https://github.com/aler9/gortsplib/blob/235cc4061beb967542b19c6be36d3ffdd8827a51/server.go#L183

therefore you have to send an OPTIONS or GET_PARAMETERS request every 50 secs.

5s is hardcoded in my surveillance station... Anyways, whats the impact of ReadTimeOut timer, if its hardcoded to 60s? Thanks,

no impact at all, the server just makes sure that a keepalive (OPTIONS or GET_PARAMETER) is received at least once every 60secs. If you send one every 5secs there are no problems at all.
