Using JW player with multi bitrates on HLS live streaming

Hi.
I have tried JW player for my website. I use Adobe Media Server and Flash Media Live Encoder. On my website, I tested with following code:
bc.. jwplayer("myElement").setup({
playlist: [{image:"image-path",
sources: [{file: "rtmp:file-path"
},{
file: "http:file-path/livestream.m3u8"
}]
}],
primary: "flash"
});


It worked on PC and iOS. Now, I want to use multi bitrates on my streaming. Users can choose bitrates from JW player. But how can I do that. Do SMIL file work on AMS 5?
I tested on JW 6 Free and will use Ads version after test configuration successfully.
Thank for your help
