[Live-devel] Dead lock on 408 Request timeout

Fri Oct 2 03:13:23 PDT 2020

Hello,

I'm facing a problem with a Samsung camera that sometimes answer a "408
Request timeout", to a SETUP command, this lead to the RTSP stream to be in
a dead lock state :
- Nothing append in the callback of the sendSetupCommand (same problem
using both TCP or UDP).
- I also won't receive nothing in the callback given in to
scheduleDelayedTask.

I'm using Debian Buster which is using Livemedia 2018.11.26. Unfortunately
i cannot upgrade the livemedia version to know if this will happen on
latest version.

I check the ChangeLog, but i don't see any modification that can fix this.

I look in the RTSPClient.cpp file and i saw there is no handling for the
408 response, but i'm not able to know if something is missing or not (even
in last version).

Maybe, it's a bug in the camera RTSP server, but this block the client
application.

Is someone has an idea about this problem ?

Thank you very much !

Please find the logs I got :
