Thanks for the comment Anthony, but I think you're using an old version. Try grabbing it from the SVN repository. I'll update the ZIP…someday.

Hi man, nice code, work good but in Flex 3 and using SDK 4.0.x I' have problem on final compiling.

I use this additional compliler arguments: -locale en_US -static-link-runtime-shared-libraries=true

I solve the problem with next way…

edit next class: com.exanimo.video.NCManagerAuto.as

- error line: 175 -> var myBandwidthChecker = new BandwidthChecker(URLUtil.getFullURL(n…
- solution : you need declarate your variable, simply add ":*"

var myBandwidthChecker:* = new BandwidthChecker(URLUtil.getFullURL(new Loader().contentLoaderInfo.loaderURL.split('/').slice(0, -1).join('/'), URLUtil.getFullURL(_streamName, _streams[0].src)));

Good Luck

@Mike Sorry I didn't respond sooner but thanks for reporting back with your findings!

Never mind. I figured it out.

For those following behind…

Apparently, in order for the smil file approach to work remotely, the smil file can NOT end with .smi or .smil as I had been informed elsewhere.

The file must end with .xml . (Or at least the way our http servers are configured, maybe this might work under different configurations, but it wouldn't work for me until I changed .smil to .xml )

I'm outtahere.

Interesting. Your example code doesn't work for me either unless I open it locally on my Mac.

Your link above ("See the NCManagerAuto Example ") brings up nothing but a blank page.

If I download the sample source files and run them, voila! I see content.

But if I upload the exact same files to my server and try to run the html remotely, no content.

So, whatssupwiddat? ; ) Inquiring minds wanna know.

I'm stumped. Things are working fine if I test the files locally, but once I upload the SMIL file, html and .swf file to my server, and point the FLVplayback component's source to the same SMIL on an http server, I don't get any video, just endless barber pole.

Any suggestions?

Does anyone know how you would go about getting a playback controller integrated into the movies using this method?

As a quick solution, I've used the FLV pathname to switch - but this would become cumbersome with larger directory paths and perhaps dynamic paths.

I'm trying to use your detection once for two sets of videos - high bandwidth and low bandwidth. Each set is contained in two arrays, but from the info above, it looks like the src value must point to an FLV in order for the checking to occur - am I correct?

If so, is there a way that I can just pass a value based on the bitrate and then determine the FLV for playback? Currently I'm trying this:

// Function determining which Array to use

function setBandwidth():Array
{

var bandwidth:String = 'example.smil';

switch (bandwidth)
{

case "HI":
return(HiBandArray);
break;

case "LO":
return(LoBandArray);
break;

default:
trace ("defaulted!");
return(LoBandArray);
break;

}
