HTTP streams fail after encoder reconnect due to network issues

Wowza Streaming Engine

Hi!

We observed several times in cases when the network connection from the encoder to the server was disrupted shortly that the RTMP streams will continue however the HTTP streams for cupertino and sanjose did not work any more.

We use FMLE as encoder and it automatically reconnects to the server:

On the server I can see that RTMP still works, but the others not:

2012-08-13 12:24:02 CEST comment server WARN 200 - HTTPProviderMediaList.onHTTPRequest: MediaList not found: ITTM/definst/ngrp:live_all - - - 176754.269 - - - - - - - - - - - - - - - - - - - - - - - - -

We need to completely stop, disconnect and connect and start the encoder again to overcome it.

Any ideas why and what to do?

Thanx,

Stephan

Hello Stephan,

Take a look at the Wowza logs for more information. You may see that the HTTP streams have been disconnected, since the time the stream was dropped is longer that the timeout Wowza has for holding the connections open.

For Flash, there is a robust player built around the the stream. For Cupertino, we don’t have this, but it is possible to create such a player that can monitor the stream, respond to disconnect events, and reconnect as you desire. See the Apple resources for examples: https://developer.apple.com/resources/http-streaming/

For San Jose you can also check the Wowza OSMF example player code and monitor for events. These are the suggestions I have. There may be others.

thanx, but also when I reload the player in Iphone or sanjose web page this happens. it looks like Wowza is not creating these streams any more. Only RTMP
