I'm finally finding a bit of time (at 10pm) to upload a little video demo that had been sitting on my hard drive for a couple of months. The premise was that I wanted to have a play with the new dynamic bitrate streaming feature in Flash Media Server so I grabbed a trailer from Apple's website, fired up Flash Media Encoder and encoded the District 9 HD clip into 3 bitrates to .f4v format: 400kbps (low bitrate), 800kbps (medium bitrate) and 1.5mbits (high bitrate).Video quality was not my primary goal here (as you can probably see from the footage), instead I just wanted to see how hard or easy it is to get something like this up and running. Bottom line: not too difficult at all.
I've got a copy of FMS 3.5, a dedicated server (UK based) with a decent bandwidth allowance so I figured why not release this into a the wild?
One thing that you should pay attention to is the actual bitrate switching. If your connection speed is very stable then you may right-click the player and choose to manual switching - let me know if you can tell when the delivered bitrate changes, I bet you can't. And that's the beauty of this technology in a nutshell: seamless switching between bitrates. Pretty neat. Note you can also click the little HD icon/bandwidth bar to bring up a console with stats about the video and playback.
I'm sure some of you will ask for sources, but to be honest there aren't really any to share. I just grabbed the Open Video Player and configured it completely via flashvars, so I have not even got a FLA I could show you. As for the video settings I used - sorry but I can't honestly remember. All I recall is that I downsized the clip a bit so the resolution is not the same as in the original source footage, and no other fancy settings were used. As I said I simply encoded using the Flash Media Encoder.
Enjoy, and let me know what you think.


Sometimes it does not work (even after 5s of waiting) when switching manually.
Thnx for the cool demo!
:D
Playback was smooth and if I wasn't looking at the HD icon I wouldn't have noticed a bit rate change (dropped to 400 a few times).
