Hello,
We’re running Wowza Streaming Engine 4.4.1 on Unbuntu 14.04.
We have setup a live application which receives an RTMP stream and transcode it to an HLS stream with 4 stream.
To be able to stream a “waiting” video until the camera RTMP stream starts, we have setup 2 modules :
-
com.wowza.wms.plugin.streampublisher.ModuleStreamPublisher
-
com.wowza.wms.plugin.streampublisher.ModuleLoopUntilLive
For those modules, we added the following custom properties :
/Root/Application/streamPublisherSmilFile : tlsloop.smil
/Root/Application /loopUntilLiveSourceStreams: _320x180,_640x360, _1024x576, _1280x720
/Root/Application /loopUntilLiveOutputStreams : Stream1_320x180,Stream1_640x360, Stream1_1024x576, Stream1_1280x720
The tlsloop.smil contains the following configuration :
<?xml version="1.0" encoding="UTF-8"?>
<smil title="Thales Live Streaming 5 flux">
<body>
<stream name="Stream1"></stream>
<playlist name="pl1" playOnStream="Stream1" repeat="true" scheduled="2016-04-15 16:30:00">

</video>
</switch>

</smil>
Another smil file has been configured for the real “live” stream :
<?xml version="1.0" encoding="UTF-8"?>
<smil title="Thales Live Streaming 5 flux">
<body>
<stream name="liveStream"></stream>
<switch>
<video height="180" src="_320x180" systemLanguage="fr" width="320">

</video>
<video height="576" src="_1024x576" systemLanguage="fr" width="1024">

<param name="audioBitrate" value="128000" valuetype="data"></param>
</video>
</switch>
</body>
</smil>
When we start the application, the waiting video is correctly streamed,
But when we start the camera rtmp stream, the waiting video is still streamed.
Here are the logs :

So we can see that the module detects the new incoming RTMP stream, but why the swith is not effective ?
