To switch from Debug Perspective back to Development Perspective, hit Cmd+F8.

Flex Builder pops up a list of Perspectives, hit Cmd+F8 again to cycle through your list.  This is very handy when you’re finished debugging and want to quickly get back to the Development Perspective without reaching for the mouse.  I occasionally stumble on these kinds of things I should already know…

So for example, bring up a terminal window and type “cd ” (notice the space after “cd”). Then simply drag your folder from the Finder onto the terminal window, let go and you’ll be ready to hit the return key to change directory to that long path rather than having to type the whole thing out.

/Users/your-name/Documents/your-dev-path/ProjectOne

/Users/your-name/Documents/your-dev-path/ProjectTwo

and ProjectTwo refers to ProjectOne in the “Flex Build Path” settings, you’ll get this warning:

Source path entry, ‘/Users/your-name/Documents/your-dev-path/ProjectOne’, is a subdirectory of source path entry, ‘/Users/your-name/Documents/your-dev-path/ProjectTwo/src’.

I don’t know about you, but compile warnings really bug me.  If there is really a problem, I’ll address it directly, but in this case, there is nothing wrong. So to remove this warning from your build, add this to your compile settings:

-allow-source-path-overlap=true

Sprint 11 is the feature complete release of OSMF.  Lots of bugs were fixed for this release including the bug I mentioned in the Sprint 10 release blog post below about the MAST plugin and the SMIL plugin not working together.  In fact, in the AkamaiPluginSample all of the plugins are working nicely together.  This sample app has become the sample for demonstrating many of the OSMF plugins that reside in the OSMF repository.

For more details on this release, see this blog entry:

• DVR Support. OSMF now supports DVR via Flash Media Server’s server-side DVRCast application. This feature allows clients to jump back in time while viewing a live stream.
• Syndication support (Atom 1.0, RSS 2.0, plus iTunes and Media RSS extensions).  You’ll see a new AS3 library in OSMF that can parse all of the major feed formats, plus the media-centric RSS extensions.  I’ve also updated the Akamai Plugin Sample app to load and parse an RSS feed and display a playlist.  If you load the MAST plugin before loading the RSS feed, you get a pre-roll ad before each video in the playlist. Note there is a bug with the MAST plugin and the SMIL plugin working together, I’m hoping to address this ASAP.
• Extended HTTP Streaming Support. OSMF now supports subclips for HTTP-streamed content, and DRM for HTTP-streamed content.

See the OSMF blog post here for more details on these features:

“The CSS type selector ‘ComboBox’ was not processed, because the type was not used in the application. ”

This warning will appear at compile-time if you don’t have a ComboBox in your app, for example.  I like to put lots of styles in a few CSS files and reuse them, but I really don’t need this information. So the way to get rid of these warnings is to add this line to your “Additional compiler arguments” in the “Flex Compiler” section of your project’s properties:

-show-unused-type-selector-warnings=false

So for example, you can see the OSMF repository is running Subversion 1.6.3 by pasting this URL into your browser:

This is the work we did for Sprint 9, which concluded on January 20th. There are quite a few changes to the API and you can read the release notes for the specific changes.  The release notes have detailed descriptions of the API changes and should ease your pain when compiling your player against this new release.

Some of the new features in this release include:

• New OSMF Sample Player with Chrome (you can view it in action here (full source is included in this release): http://mediapm.edgesuite.net/osmf/swf/OSMFPlayer/OSMFPlayer.html)
• New SMIL plugin
• HTTP Streaming Support
• Enhanced plugin support

We are currently heads down on Sprint 10, which will wrap up on February 24th.

A much faster way to do it is to launch the Terminal application, “cd” to the directory where your files exist, and use this command:

for f in *.abc; do mv ./”$f” “${f%abc}doc”; done

All of  your “*.abc” files will be changed to “*.doc”.

All the projects I work on target Flash Player 10 or higher, and I can’t keep count of how many times developers have asked me, “how can I make this code work with Flash Player 9″. Simple answer, you can’t, so stop asking ;)
