Re: [flexcoders] Re: Buffer progress bar for streaming FLV

Thu, 31 Aug 2006 07:16:32 -0700

Hi Chris,

In VideoDisplay, you can subscribe to "playheadUpdate" event and use playheadTime, which is similar to NetStream.time.

You can subscribe to "stateChange" event and watch "BUFFERING" in event handler, if you want to show BUFFERING status to user...

Awesome!!! Worked perfectly. Thank You.

With all this in mind, is there a way to pull this of using the
<mx:videoDisplay> component?

I created my app using that component but I could not figure out how
to access the stream. I figured I would do a rewrite using the
netStream object if necessary, but I would love to avoid doing that if
possible.

Thanks Again,
Chris
