If you care to look at the following url, which you are using in your player, you will se that the meta tag had been added automatically.
This is the output from the above url
[B]<meta base="rtmp://126.96.36.199/live/_definst_" />[/B]
<video src="mp4:livestream_source" system-bitrate="1000000"/>
<video src="mp4:livestream_240p" system-bitrate="350000"/>
<video src="mp4:livestream_160p" system-bitrate="200000"/>
This is the jwplayer.smil url that I was refering to in my other posts.
You are corect that you do not need the meta tag in the smil files that you create to use within Wowza but you are incorrect in your assumption that JW Player does not need the meta tag in order to playback RTMP ABR.
In order for the player to display a switching menu with video sizes rather than bitrates, you need to add width info to your origin smil file.

because even using the test player integrated with streamEngineManager i could not load the first live stream. Instead of the second url that work perfectly.
