Missing title. Missing body.

Hello,

We do have a module that allows for a playlist scheduled streaming of live streams.

StreamPublisher Module Information

Note: For live stream sources, use -2 for the start parameter.

Best regards,

i’m already using that StreamPublisher package but what i am asking is

<smil>
    <head>
    </head>
    <body>

        <stream name="Stream1"></stream>
        <stream name="Stream2"></stream>

        <playlist name="pl1" playOnStream="Stream1" repeat="true" scheduled="2016-04-15 16:00:00">
            <video src="mp4:sample.mp4" start="5" length="5"/>
            <video src="mp4:sample.mp4" start="50" length="5"/>
            <video src="mp4:sample.mp4" start="150" length="5"/>
        </playlist>

        <playlist name="pl2" playOnStream="Stream1" repeat="true" scheduled="2016-04-15 16:30:00">
            <video src="mp4:sample.mp4" start="0" length="-1"/>
        </playlist>

        <playlist name="pl3" playOnStream="Stream2" repeat="true" scheduled="2016-04-15 16:00:00">
            <video src="mp4:sample.mp4" start="30" length="5"/>
