Adaptive bitrate streaming and Akamai


Hey everyone,

I need to set up some adaptive bitrate streaming and I'm having some trouble to find this out...

Is there any way to my streaming keep "watching" the bandwidth and modify the quality of playback?

If this isn't possible how can I add a button for quality changing embedded in my player?

On the thread(http://www.longtailvideo.com/support/jw-player/28842/working-with-playlists) I've read about using labels to link different quality of streams, but this didn't work as in the thread...

Here is the code:

sources : [
{
file: "http://carna_chiclete-lh.akamaihd.net/z/nova_100@75411/manifest.f4m", label: "100",
type: "flv"
},{
file: "http://carna_chiclete-lh.akamaihd.net/z/nova_200@75411/manifest.f4m", label: "200",
type: "flv"
},{
file: "http://carna_chiclete-lh.akamaihd.net/z/nova_200@75411/manifest.f4m", label: "300",
type: "flv"
}


I'm using .f4m format.

Are you currently broadcasting? The file just spins once, then stops.

I would simply just use the m3u8 file, because the f4m file only has one bitrate.

This is working.

I might ask Akamai, since this is their provider.

Ethan,

I did some tests and with a rmtp demo the stream seems to work but with my http stuff doesn't...

With rmtp demo: http://www.novaconteudo.com.br/player/sensation_1new/

Code for smil:

bc.. <smil>
<head>
<meta base="rtmpe://cp134706.live.edgefcs.net/live/" />
</head>
<body>
<switch>
<video src="demostream_1_300@2131" system-bitrate="300000"/>
<video src="demostream_1_800@2131" system-bitrate="800000"/>
<video src="demostream_1_1200@2131" system-bitrate="1200000"/>
</switch>
</body>
</smil>



Http: www.novaconteudo.com.br/player/sensation_new/

Smil code:
bc.. <smil>
<head>
<meta base="http://skolsensation-lh.akamaihd.net/"/>
</head>
<body>
<switch>
<video src="skolsen_300_1@116939" system-bitrate="500000" width="1280" height="720" />
<video src="skolsen_200_1@116939" system-bitrate="200000" width="854" height="480" />
<video src="skolsen_100_1@116939" system-bitrate="50000" width="640" height="360" />
</switch>

What could be wrong?

You wouldn’t do http streaming inside of a smil file, I think that is it.
