I read the article here http://www.wowza.com/forums/content....-stream-starts.

I had two playlists that are scheduled to play at two different time.

<playlist name="pl1" playOnStream="Stream1" repeat="true" scheduled="2014-07-07 11:00:00">
<video src="mp4:sample.mp4" start="0" length="-1"/>

<playlist name="pl2" playOnStream="Stream1" scheduled="2014-07-07 11:30:01">
<video src="mp4:another.mp4" start="0" length="-1"/>
The first video "sample.mp4" will start to play at 11:00:00. It is assuming that sample.mp4 is 30 minute long.
After sample.mp4 finishes playing, the next video "another.mp4" will start to play at 11:30:01 immediately.

Here comes to question:
At 11:28:00 I insert a live source and the output screen jumps to the live, everything runs fine.
However, when it is 11:30:01, the live stream was terminated and the filler video "another.mp4" was switched in!
Why is this the case? I thought the live stream will be at the first priority no matter there is any scheduled playlist.

How to fix this problem? I would like the live stream to be in place in any circumstances. (Ignore the scheduled playlist anyway)
