The Shumway Open SWF Runtime Project 99

Posted by Unknown Lamer from the now-there-are-four dept.
theweatherelectric writes "Mozilla is looking for contributors interested in working on Shumway. Mozilla's Jet Villegas writes, 'Shumway is an experimental web-native (Javascript) runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals: 1. Advance the open web platform to securely process rich media formats that were previously only available in closed and proprietary implementations. 2. Offer a runtime processor for SWF and other rich media formats on platforms for which runtime implementations are not available.'" See also: Gnash and Lightspark.

    I love the Free / OSS nature of something like this, but one of the absolute best** things about Flash is the ActionScript language (specifically AS3) (and to a lesser extent flex).

    Since it is based on ECMAScript, it offers nearly everything JavaScript does and more. Classes, Inheritance, Polymorphism, both dynamic and static typing, etc, etc. And some things I find truly awesome such as the EventDispacter pattern and DisplayObject event bubbling.

    So what are the chances of ActionScript being considered for something like this? Are there legal hurdles that make it a non-starter?

    Also, how does this compare to other OSS flash players like Gnash? Conceivably this could solve the biggest problem with Flash, the lack of security involved when the player is proprietary.

    **Yes, Adobe stagnated and got lax about security as well as bundled toolbars with the plugin as well as other privacy implication with SharedObjects. However, as a scripting and vector animating platform, Flash was amazing tech. And it makes damn nice RIAs and did great for video for its time. However it's clear that time is over due to some serious missteps on Adobe's part. So please don't get me wrong, there are many valid criticisms of Flash, but it was an innovative technology (and still is to a much less extent).

        Not all SWFs are AS3 -- quite a few of the older ones out there are still AS2 -- and all but two of the demos they've provided are AS2.

        By looking at the code, it looks like they've implemented maybe half of the opcodes in the SWF spec for AS3. They got the easiest ones for graphics, but they are missing all the networking ones, most of the effect, and a lot of the event handling. They still have a LONG way to go before they can say they run even a portion of the Flash apps out there.

      We got our first "no flash" order on a project awhile back, and I have cried a little on the inside every day I have worked on it. My first introduction to flash was compiling SWFs in Linux using the MXMLC compiler. In fact, I even wrote the Actionscript 3 syntax highlighting rules for KDevelop (Kate) 3.5, because that's what I had available on my system to use. The flash platform is an AMAZING technology stack, and it is sad to see it go to waste behind a wall of patents wielded by a bafoon of a company.

          I can promise you flash is only as slow and buggy as the flash developer. Unfortunately, there are hordes of the sluggish variety mucking about. Security is a non issue. In fact, flash is one of the easier things to get clearance on in our government contracts. I will however be the first to admit the platform would do much better if the whole thing were given to Apache. The problems with Flash are political, not technical.

I'd wager a lot of AS3 "developers" are of the same calibre as AS2 "developers" - that is, artists who have diversified a little into scripting but don't really have a good understanding of programming or optimisation. The end result is as you said, loads of flash applications that murder your machine when they run. Also it took Adobe till Flash CS5.5 to make an IDE even remo

Now if the browsers could only agree on a standard for an efficient binary serialization format with object references like AMF....

        Which is why a browser-based method is better than a plugin-based method for stuff that Flash does. After all, if you allow Flash for one site, who knows what sorts of Javascript and resources it pulls from other sites?

        But a browser based version or HTML5 means site-specific restrictions are honored - a Flash video that wants to pull in javascript from ad trackers can do it via the Flash plugin, but if it was in HTML5 or a browser implementation, will still remain blocked.

I despise going to read a page with ads and other shockwave sidebar widgets that make noise or chew up CPU cycles and have no way to pause/mute/stop them. It also bugs that you must reload the entire page to get a flash app to restart.

    It's beyond me why Macromedia/Adobe never wanted us to have those essential controls. The only thing we get, in some rare cases, are the ability to prevent the app/player from looping, or to turn down rendering quality.
