RTSP over HTTP, killUnidentifiedSessions

[L_Eric]

Hi,

I’m using a Client (player) that consume the Wowza server video streams via RTSP over HTTP protocol.

The 2 required channels for RTSP over HTTP are properly opened with a POST(Client -> Server) and a GET (Server -> Client) methods.

So far, so good… everything works fine. The Video Stream (data) is sent through the Server->Client channel.

Problem occurs after a couple of seconds (around 5 sec), the wowza server kills the Client -> Server connection (killUnidentifiedSessions: Killing unidentified session).

Here’s what I tried so far to keep-alive the client->Server connection:

• I adjust the values of the VHost.xml unidentifiedSessionTimeout to higher values, but it only delays the killing of the Client->Server channel.
• I sent a RTSP OPTIONS (every 10 sec.) on the Client -> Server channel to keep alive the connection, but server still kills the connection.
• I sent RTCP Receiver report (every 5 sec.) on Server->client channel, but server still kills the connection.

The only workaround that I found was to set the VHost > unidentifiedSessionTimeout to 0, so Wowza never kills the connection.

Is there any configuration or keep-alive mechanism to prevent Wowza server to kills the client -> server connection?

Thanks,

Eric

Hi Eric, did you make any progress with this? In my set up I’m also seeing killUnidentifiedSessions logged and struggling to get to the bottom of it.

UnidentifiedSessionTimeout - Time, in milliseconds, that the server will wait for an unidentified client session before disconnecting the application. You do need to set this to 0.

I would send a ticket so we can see if there is an issue with a firewall or port forwarding that’s slowing the connection time down.
