I am having some serious problems with video performance. Let me try and explain in a little more detail - I am using flex to build a jukebox application that supports audio (mp3 files) and video (flv files). It's actually an AIR app that will run on the user's desktop playing files stored locally. The mp3 side of my app works perfectly well with no problems what so ever, however there is a major issue I am having with the video player… the video loads fine and begins to play without any problems but as soon as there is any interaction with the app’s interface the video begins to stutter/stop for a few milliseconds before continuing to play once more? At first I thought this was simply a memory issue I had with the machine I was using to develop the app but I upgraded my RAM to 6GB (yes that’s right - a full 6 GB) and the issue still persists? Any ideas or suggestions you have regarding this problem would be hugely appreciated! Many Thanks Adam Hi Tony,

That would be a much cleaner way of implementing the behavior. My experience is that the speed measurement is at best a crude measure however, and that things generally work out best if you don't try to make things too accurate. Hi Tom

So you should calcul it the most time possible not just 1 time and especially, NEVER calcul your bandwith when your app starts because the browser is loading other files such as CSS, HTML, other images... so you get a totally wrong value! Instead you should use the progressevent of the video player to calcul the bp. The value will be more accurate. FrenchTom But, the bandwith is totally dynamic isnit?

A NO_BITRATE_MATCH error usually occurs when you try to play (or pause/stop), a VideoDisplay when it doesn’t have a video loaded.

So if you have autoLoad set to false (that’s not the exact name, but it’s something like that), then you can’t call play() until you have called load().

By default, setting source does call load() however, so I’m not sure that’s your problem.

It’s very likely that you are trying to call play(), pause() or stop() somewhere in your program when there is not a video loaded.

Hope that helps
Tony
