Yahoo! have launched their Flash Developer Center, and among the interesting articles and downloads is this article about runtime font embedding in Flash CS3.
It looks like embedding fonts might be a hell of a lot easier in the latest version of Flash. Anyone who’s dabbled in Flash and non-standard system fonts knows it’s been a pain in the ass in the past to get working (hidden font fields off-stage, etc), so I’m eager to see how things now fair in the latest version of Flash.
As for the other stuff up on the site, I expect they’ll flesh out things as time goes on. I wonder how easy to skin and customise their components are, as one of the reasons people opt for Flash is because it allows them total control over the look and feel of the user interface.
Another thing I’m wondering about is the accessibility of their components. I’m writing this on a MacBook and checked out their components in Firefox (admittedly not a great browser when it comes to tabbing and Flash), but even when focused within the Flash movie my tabbing didn’t seem to do anything.
I’m a big fan of Yahoo’s User Interface Library efforts, and now it seems they’re going to open up a lot of their Flash stuff (including best practices on accessibility).

Unfortunately, due to the different virtual machines that process ActionScript when dealing with AS1/2 or AS3, it’s not straightforward to communicate between content developed in the latest version of Flash/Flex and older content.
Thankfully, a few people have come to the rescue in the form of SWFBridge and ActionScriptBridge. I’m sure either is likely to come in handy.
Adobe Live was a two-day event held in Angel on the 5th-6th June which showcased a number of new technologies on offer from Adobe, along with various seminars and talks from industry professionals.
Below are the rough notes I took (more of a brain dump, but I haven’t the time to format it right now).
- Flash 9 at 84% as of March this year
- Flex 3 will allow greater control over skinning/creative aspects
- Check out http://www.picnik.com for a Flex-based online image editor
- Video encoder not packaged with normal Flash; have to buy CS3 package or professional version it seems
- Top5 mobile phone makers signed up to put Flash on their medium/high end phones
- Flash Lite 3 announced
- Adobe Device Central is database and emulator of mobile devices running Flash. Very impressive. Can calibrate performance of machine to the performance of the device you’re previewing for. Aiming to update device support list every quarter.
- In Flash CS3, Quicktime export and video importing improved
- Can deinterlace video when importing
- Fullscreen and caption buttons now in video skins
- 3D won’t import into Flash from Photoshop; will be a 2D render of the last frame
- Title and Description metadata now part of the .swf you publish from Flash
- Adobe Media Player allows you to skin your player/channel according to how you want (I think it runs off RSS)
- Apparently, when it comes to the interactive aspects of AMP you’ll need Flash Media Server (i.e bringing on an ad, overlay, dynamic ad playlists, etc)
- AMP does bandwidth detection
- Adobe are thinking about IPTV, but can’t announce anything
- ABC, Desparate Housewives, etc run their video online via FMS
- http://www.videojug.com is a progressive download site
- Encrypted streams coming later in the year (dunno if through AMP or not)
- Flash Media Server runs off Windows, and will remain Windows for a good time. Priority is to add features for the product rather than add cross-platform support
- Photoshop (PSD) import works with older PSDs regarding retaining layers; don’t need a CS3 PSD to enjoy this functionality
- Focus on mobile interfaces is that space is at a premium; don’t have a weather button that loads a new page that gives you loads of options – have that initial weather button immediately bring up general weather information and have futher weather options underneath. Every click/page should be providing some essential information; make the steps between information as few as possible
- iPhone realises that menus for different phone apps (e.g. images, mp3 player, etc) shouldn’t be generic; you want to perform different tasks/things in each section, so the menu should tailor specifically for what the application’s trying to achieve. Doesn’t always make sense to have generic menus on all applications
- Check out Flash Cast; doesn’t seem to use the mobile browser. MTV use it a lot to push their rich visual-based content
- Mobile content can’t be a port from the desktop; need to specifically target mobile users
- Mobile development isn’t generic; you need to look at the performance, input methods and screen size of the mobile device you’re planning on targeting
- On the low-end devices you can still bring in dynamic data, so on those lower devices you can present the same data but with fewer animations, etc
- In the past, applications based firmly in the browser, mainly Windows-based
- Check out http://www.finetune.com. Can’t just listen to a song; need to hear it as part of a playlist. All content is being licenced, so legit site
- Finetune Flex application has iTunes integration, so it can look in your iTunes library and suggest different playlists based on what music you already have
- Apollo has recently added local database support, so seemingly mirroring Google Gears
- Plan is for Adobe and Google to form a common API for use in Gears and Apollo, but at early state of discussions
- Both Gears and Apollo use SQLite
- Apollo APIs are NOT available to ActionScript 1 or 2
- Scout – Apollo-based HTML/JS debugger
- Apollo uses WebKit Open Source Engine (same as Safari, KHTML), because it’s open source, small filesize, proven, and also offers mobile support
- SQLite works as a file basically; you say where you want the SQL file, and then all API calls are made to that file. Single install, easy
- Apollo Functionalty – Network Detection, File I/O, Custom Window Chrome, Multi-Window, Native Menus, Drag n Drop, Clipboard access, System Tray and Dock Notifications, Application/Installer Signing, Application Icons, File Type Registrations, Background applications, Application Update APIs, Supports XML-RPC, SOAP, Rest-Based Web Services, Binary and Web Socket support
- If you want to build an application with deep hardware integration, then probably go with something like C++, .NET, etc. However, Adobe believe there is a gap between browser-based applications and those hardcore hardware-based applications; this is where Apollo fits in
- Much lower learning curve to building applications in Apollo, as most the skills are known by web developers
- Workflow – Develop/debug in IDE or command line, package application for deployment, distribute application package
- Apollo requires a runtime install, and then for each application a specific application install
- Looking into getting Apollo runtime install fed in via Flash install in the future possibly
- Apollo runtime is about 5-7MB install
- .air files are the Apollo application extensions, and they’ll work cross-platform
- Hoping to have runtime and application files available as downloads, so when distributing content you can package in the runtime too
Flash/Flex working together
- Fireworks CS3 has Flex components built-in which you can export at the same time as you export your image. You select “export images and MXML” option
- Main advantage of this is that a designer can create a layout/design which you can export from Fireworks and use as the starting blocks for your Flex application (you can choose the generated MXML file as being the main file for the new Flex Project you’ve created)
- Two ways a designer can produce assets within Flash that can be used by a coder; export the timeline as MXML, and COMMANDS > MAKE FLEX COMPONENT. This extention is available within Adobe Labs right now. Exports it as a .swc file. HAS to be a movieClip in order to export it. Within Flex you then update your library path to point to the location where you’ve exported your .swc and then Flex can use the new component.FLEX BUILD PATH > LIBRARY PATH (via right-clicking top directory within your project layout panel)
- You add a namespace for your local generated components from Flash, and then Flex can use your components the same as any other, with all the properties exposed via code hints
- Can export from Illustration .swfs that can then be used as skins for Flex components
- Flex 3; better for designers – easier to import assets, will be able to skin easier
- Flex 3 Beta to be released very soon
- Fireworks is the only graphics application that features Flex components and also allows you to export directly to MXML
- When you export for Flex, it HAS to be 25FPS, as that’s the default framerate for Flex applications. There are other caveats too apparently, but the feature is still in Beta, so expect changes and increased functionality when finalised
- If you export something with more than one frame from Flash and a Flex component, then those different frames will be treated as different “states” within Flex
- Adobe dealing with the Spry framework for AJAX
- Spry is fairly design-centered
- 1.4 is current release, with 1.5 currently on Adobe Labs
- Distributed on an Open Source Licence
- Find the effects demo of Spry’s stuff (looks like script.aculo.us)
- Looks good for form validation (ticks, date checkers, etc)
- Dreamweaver CS3 supports Spry (Spry widgets, effects and data sources)
- Spry looks to be clean code-wise; it adds class names to DIVs
- Can use data binding to bring in stuff according to the data source
- Lots of demos and sample code in with Spry
- Flex/Flash allows you to push information to the browser, rather than polling the server
- Look for the flipbook medical demo; looked excellent!!!
- FABridge is used to communicate between Flex and AJAX
- Kristophe Konrad Flex’s SQLAdmin for Gears demo – look it up
- Nice demo using Flex to extend Google Maps; used Flex to allow user to scroll map and have another user see where he’s scrolling, can see other person via webcam, can draw on map and other person see it in real-time, etc
- LifeCycle Data Services; enables real-time pushing of data from/to AJAX or Flex clients
- Fresh is an Apollo application built using the Yahoo! Model for AJAX (doesn’t use Flex or Flash)
- Flex 3 applications will still target Flash 9 player
- Both Apollo and Flex 3 will be available this year
- Able to extend Flex builder (Eclipse) easier, so you can add your own extensions, etc
- Because Flex 3’s SDK is open source, Flex builder will be able to support multiple SDKs, so you can choose which SDK you want to publish with
- Flex 3 supposedly better regarding localisation and accessibility
- Advanced datagrid in Flex 3; can sort on multiple columns at the same time, not just one
- Can format individual cells (assign cells their own styles)
It seems Adobe have relented and included DRM within Flash video with the announcement of Adobe Media Player.
Hot on their heels is Microsoft, who’ve also announced Silverlight, a plug-in for Windows and Mac that’ll work across the major browsers too.
Who will win? Hopefully Flash, but it’ll depend on which of the big boys incorporate what technology on their sites, despite the apparent lacking in Silverlight’s feature set compared to Flash. I’d also like to think the ease of development might also help drive either technology.
This interview with Niqui Merret and Aral Balkan makes good reading for those trying to work out the general situation regarding Flash and accessibility.
I’ll be keeping an eye on Niqui’s site in future too, as it looks like being a good resource for anyone looking at accessibility in general.
It sounds like Flash may not work 100% as expected in Windows Vista unless a user’s using the latest version of the plug-in (9,0,28):
Senior Product Manager for Adobe Flash Player
It seemingly relates to a subset of specific functions which conflict with Vista’s security model:
- Shared objects (Flash cookies)
- Local Connection (Flash movies talking to each other)
- File reference (saving and opening files within Flash)
- Express Install (auto-updating a user’s version of the plug-in)
I haven’t a copy of Vista to check any of this unfortunately, although I’ve no reason to doubt it. It sounds like something that might only affect users upgrading from XP and retaining older versions of the plug-in, or developers, developers, developers…
I’ve been looking into whether better-quality Flash video is produced when sticking to dimensions that are divisible by 16. This seemingly has been the rule with older codecs, but I’ve had to investigate the issue for Flash 8 .flv video. Adobe doesn’t seem to think so, stating:
Although these ratios are standard, and should be used to avoid distorting the video, the size of the encoded video is not set in stone. The original web video sizes used heights and widths that were evenly divisible by 16. This was mandatory for many early codecs. Although this is not necessary for modern codecs, you should stick to even heights and widths.
This doesn’t quite tally with the advice on On2’s site (producers of the Flash 8 codec):
If you reduce your video size (image dimensions), your picture will be sharper. Another small factor you may consider is that optimal frame sizes are divisible by 8. That means that if your image dimensions (width and height) are divisible by 8, you will be wasting as few bits as possible on encoding data for portions of the video which do not actually appear. This is a complex issue relating to the way image compression uses 16×16 and 8×8 blocks to form an image.
A forum post by Zappu here enforces the 16/8 rule, as does this entry on MultimediaWiki. Conversations with Dave Curtis (hello Dave!) have been very helpful and also seem pretty conclusive on the “16 issue”.
It’s probably best to stick to dimensions divisible by 16, but not set in stone. Complex clips with lots of motion and/or panning would probably benefit from the 16-rule to a greater extent. I hope to produce some encoded tests myself, but if anyone has any in the meantime the links would be much appreciated.
Why is there so little clear information on this on the web?!?
I haven’t experienced this issue yet, but I’m glad it’s been highlighted and fixed before I do.
Papervision3D’s 3D stuff in Flash 9 shows just what the latest version of the plug-in is capable of. This panorama is especially impressive viewed full-screen (click icon at the bottom-right of the screen).
More demos can be found here.
