Smokescreen, a JavaScript-Based Flash Player

Posted by kdawson on from the now-to-optimize dept.

Tumbleweed writes "How to make Steve Jobs your mortal enemy: Smokescreen, a 175KB, 8,000-line JavaScript-based Flash player written by Chris Smoak at RevShock, a mobile ad startup, and to be open-sourced 'in the near future.' From Simon's blog: 'It runs entirely in the browser, reads in SWF binaries, unzips them (in native JS), extracts images and embedded audio, and turns them into base64 encoded data: URIs, then stitches the vector graphics back together as animated SVG. ... Smokescreen even implements its own ActionScript bytecode interpreter.' Badass!"

    Very impressive! However, given Flash's performance issues even when compiled natively for mobile devices, this is more of a proof of concept then something usable.

      Hey, now those flash ads can bog you down EVEN MORE, and just in case you left Javascript on with flash uninstalled, you get the benefit of it as well!

      Honestly, I think this will force most people to turn Javascript off if nothing else.

      most people or most nerds? I don't think most people even get ABP, even if they run Firefox, let alone actually know what Javascript is or that its something that can be disabled. Turn off JS these days, and practically nothing works. better would be a plug-in which just prevents Smokescreen from being loaded in particular.

      On a side note, why are people suddenly so in love with the term "infographic"? Can't we call it a "graph" or "chart"?

      It is because your boss's nephew knows how to make graphs and charts. Never word anything in a way that might cause you to be replaced by your boss's nephew.

      On a side note, why are people suddenly so in love with the term "infographic"? Can't we call it a "graph" or "chart"?

      First, infographics isn't a new term, it's a been around since the early 1990s, at least.

      Second, infographics is a more inclusive category than charts or graphs. Charts and graphs tend to be quantitative in nature. A good example of an infographic is a map: calling a subway map a chart is a stretch. (Yes, I'm aware of nautical and aeronautical charts.)

      So, when Dan suggests that Flash has legitimate uses for infographics, I think that's a perfectly legitimate use of the term.

  2. I only wonder how the speed will be by gearloos · · Score: 3, Insightful

    I just wonder how efficient it will be for the rendering times. Some flash is already bordering on bloatware. Add in taking it apart and re-rendering and I start to wonder if its worth it to wait that long.

    Jobs doesn't care about flash content, he cares about flash. If the flash content can be used without flash itself, well, that'd be great.

    Not sure why, but slashdot's headline writers are starting to sound more and more like tabloid writers. Why not say "Smokescreen to Adobe: flash off!"

      Jobs doesn't care about flash content, he cares about flash.

      Sorry but that's just not true. Did you miss the recent uproar about the new iPhone SDK agreement? The new agreement bans any applications that were not natively written in C/C++/Objective C. This updated agreement was released only weeks before Adobe CS5 was to debut with advanced tools that would allow the porting of flash apps to the iPhone. If flash itself was the problem then such a clause would not have been added.

  4. Javascript trumps Flash? by RLBrown · · Score: 4, Insightful

    My take is that this proves, perhaps to a significant degree if not completely, that Javascript/HTML5 can do anything that a native Flash engine could do . So why build in Flash? Go straight to Javascript/HTML5. I do not think Steve Jobs will be unhappy about this at all.

  5. the iPad needs this by Lord+Ender · · Score: 3, Insightful

    A certain sort of video (the kind you can't find on Youtube) comes primarily in Flash format. This sort of video seems to drive the adoption of new technology. If this can bring said video to the iPad, sales are certain to engorge.

    Other than Apple's non-support of Flash on the iPad, this has nothing to do with Apple. This is an Adobe Flash emulator written in JavaScript.

    I don't buy your take on things.

    I think it has a lot more to do with being the gatekeepers for content (and continuing to get a cut of the profit) than with flash content itself. They don't want people using apps and games on their platform that you didn't buy from the app store, hence no Flash or Java on the i-devices.

  8. Re:Good test of 'open platform' by Jer · · Score: 3, Insightful

    Why should Adobe care? As far as their history goes, I think Adobe would love it if they didn't need to support a flash plug-in. They certainly don't seem to want to invest a lot of time/money into keeping it up-to-date.

    Adobe makes their money on Flash development tools. They give the plug-ins away for free to sell more dev kits. I could see them kicking up a fuss over open source compilers, but not interpreters.

    Like others have said, you are confused about JS. It is a beautiful language that has been cursed by the browser. The only features I'd like to add would be (explicit) multi-threading, and typing beyond var. JS is a truly object oriented language that offers dynamic scoping and functions as first class objects. I understand there are some command-line interpreters that actually allow those, but I've only used it in the browser. If any of those languages you mentioned had made their introduction via the browser, you'd hate them equally or more so.
