Can't make RTMP Dynamic Streaming work... always falls to lowest bitrate

Hi!

I'm following the directions on RTMP Dynamic Streaming as suggested here:
http://www.longtailvideo.com/support/jw-player/jw-player-for-flash-v5/16012/setting-up-rtmp-dynamic-...

But when I play the video, it always falls to the lowest bitrate, and I know I have the bandwidth, I have a corporate 100Mb line here. And when I try to view the HD video alone, it plays just fine. The issue is when I use levels.

I'm using Amazon CloudFront RTMP streaming (wich is FMS 3.5 and supports Dynamic Streaming).
http://docs.amazonwebservices.com/AmazonCloudFront/latest/DeveloperGuide/RTMPStreaming.html#d0e4686?...
"CloudFront supports all the features in Adobe Flash Media Server 3.5 related to dynamic streaming, which is the ability to switch between different quality streams during playback."

I see the working examples and see my implementation and I have no idea what could be wrong.

Here is my sample, could anyone see what is going on?

Thanks!

The bitrates should be entered in kbps. You use bps, so the player is presuming all videos are 1024x the bitrate they actually are.

I would also like to add that I tried it using one instance of Wowza 2 server and it happens the same (as FMS 3.5 running in CloudFront), it always falls to lowest bitrate. So it must be something in my implementation, and not the streamer.

Any ideas?

Thanks!

Ohh sorry... let me try that. It's always is the simplest mistakes.

Thanks!

That did it.... sorry, my bad.

Thanks!

One more quick question:

Using HTML5 mode, can I also use the levels to set different bitrates for dynamic streaming? Or that only work on Flash mode?

That only works for Flash. In HTML5, there's no way to measure bandwidth and/or adapt the stream smoothly.

Ok, thanks! :)
