Brian Riggs, tech lead for the OSMF (Open Source Media Framework) project gave a nice overview of the framework this past Thursday. You can view the recorded Acrobat Connect session and check out lots of helpful links here:
If you are uploading pictures to Facebook, the largest dimension (either width or height) is 604 pixels. If you upload a picture with a width or height larger than that, Facebook will resize it, maintaining the aspect ratio, but who knows what algorithm they are using to do that.
If you want the best quality photo, load your photo into Photoshop, make the largest dimension 604 pixels, save it, and then upload it to Facebook.

Check out my post on the OSMF (Open Source Media Framework) blog about the new cue point feature in OSMF:

I was trying to instantiate a class using the class name as a string, like this:
var pluginInfoRef:Class = getDefinitionByName(“com.foo.bar.MyClassName”) as Class;
But kept getting this error:
ReferenceError: Error #1065: Variable MyClassName is not defined.
Which really has nothing to do with the problem since “MyClassName” is not a variable. I think the problem here is the SWF compiler in Flex Builder is optimizing out any imports that don’t get instantiated, so at run-time, the class really doesn’t exist in the SWF. The work around I came up with is to add this line:
private static const forceReference:MyClassName = null;
This causes the SWF compiler to pull the class into the SWF and getDefinitionByName started to work. Now, I’d like to have that 20 minutes back.
Do you ever get baffling build errors after importing projects? Sometimes the compile errors are related to project settings, such as library dependencies, missing SWC files etc. But after fixing those problems you still see errors after doing a “Clean…”?
Take a look at your build order preferences, you’ll find the dialog shown below under the Flex Builder preferences (Cmd+”,” on a Mac), not the project preferences. Apparently, Flex Builder adds items here in the order you import them, so mix them up here based on dependency and when you tell Flex Builder to “Clean..” it should build everything correctly.
So you sit down to encode some content at varying bitrates so you can dynamically stream your content. You start with a low bitrate. Then you duplicate that one so you can do another at a higher bitrate with the same settings. But before you hit “Start Queue” you decide to double check that last one and make sure you set the bitrate to what you thought you set it to. But no, it’s set to the first one. You do it a few more times and… …what the f*#%! The bitrate change will not stick! This is an incredibly annoying bug.
The only way I’ve found to make it “stick” is to select VBR, set your desired bitrate, then choose CBR. It sticks when you do that. How this got past the QE’s at Adobe I have no idea.
If you use two monitors and then remove one, for example from your laptop, you may notice that Firefox thinks the other monitor is still there and opens it’s preferences and windows off screen. To fix this without re-connecting the monitor:
1) Quit Firefox
2) Hold down the option key while you start Firefox
3) Select “Reset toolbars and controls” and click “Make Changes and Restart”.
One of the things missing from OS X is the ability to ctrl+click a file and copy it’s full path to the clipboard. It amazes me that this feature is missing from such a robust OS. This tip should make your life easier. You can see the full path in the title bar when you select a file in the Finder.
1) Open a Terminal window and type this command:
defaults write com.apple.finder _FXShowPosixPathInTitle TRUE
Of course replacing TRUE with FALSE will turn this feature off.
2) Restart the Finder:
Cmd+Option click the Finder in the Dock and select "Relaunch"
Note this works from User accounts as well as Admin accounts. No need to “sudo” from within the User account.
applicationComplete is the last event dispatched by your Application object on startup. So if you need to add objects to the Stage at startup, this is the one you want.
creationComplete is a little more involved and depends on whether we are talking about containers or components. For specific info on this see this article: http://tinyurl.com/mx8u68
