Re: [flexcoders] Re: How to access IP camera with Adobe air?

[James Ong]

You need to convert that into MPEG-4 format before it can be playback on
Adobe AIR.
Try google for flash video tutorial and NativeProcess to give you some idea
how to implement it.

The NativeProcess function in AIR is useful to control FFMPEG application
in the background which can be convert the video, once the conversion
is complete, you can implement your AIR application to load the video and
playback.

As there are various type of video camera, we have no idea if this work for
your case.

[flexcoders] App-level Spark Label style vs. Button fontSize -- bug?

[William Mitchell]

I've got a really really basic question about the scope of application level 
styles.

At the app level there's a

s|Label  {font-size:11;} 

style and with that in place it seems that *every* Spark Button has an 11-point 
label and that can't be overridden!  Is there any way to override that 
app-level setting on particular buttons?

Here's the code:


http://ns.adobe.com/mxml/2009"; 
   xmlns:s="library://ns.adobe.com/flex/spark">

@namespace s "library://ns.adobe.com/flex/spark";
s|Label {
font-size: 10;
}




If you run it, what'll you'll see is a 10-point "test" button, not a 30-point 
"test" button.

I believe I'm seeing this behavior because SparkButtonSkin's labelDisplay is a 
Label.  I can make a new button skin and set the fontSize on labelDisplay and 
that solves the problem, but that's pretty clumsy.

Even doing b1.setStyle("fontSize", 30) in a creationComplete handler or a click 
handler for another button doesn't cause the font of b1 to change.  (I stepped 
through the framework code for that call, and I just didn't see a place where 
labelDisplay's fontSize is ever touched.)

It sure seems like a bug to me but maybe I'm missing something.

p.s.
You might ask, "Why not just remove that app-level style for s:Label?"  That's 
a possibility, of course, but in the app where this problem turned up, there 
are a LOT of buttons and labels that would then need to be given a style in 
some other way.

It is also worth mentioning that if any of you have spent any time being a
Windows desktop system administrator, you will appreciate the management
features that only IE has in conjunction with group policy.
Changing/enforcing proxy settings, certificate authorities, cache policies,
homepages, look and feel settings and more can be done by just flicking a
few settings in Group Policy.

To do the same with Firefox, you'll have to modify a bunch of files on
installation, and on every change, push out a new prefs.js file. Sounds
easy enough, but try doing that when you have different settings that apply
depending on the site the user is at, the groups they're a part of, etc.

Unfortunately, none of the alternative browsers seem to pay much attention
to the enterprise, so IE is pretty safe until there is a reasonable
alternative.
