Flash :: Swf Files Have Inbuilt Methods For Interfacing With Javascript?
Feb 5, 2011
I don't work with Flash and consequently know nothing of it, but I have the task of embedding a swf film into a web page. I know nothing about the swf's internal design, other than it plays a short film. I'd like to control when the swf starts playing, rewind it (it will be played infinitely), and possibly even cache it in the browser. It will be part of a Javascript-powered rotation of images, in which the <img> element will be temporarily replaced with an <object> for the swf.
My question is do swf files have an interface for Javascript built-in when compiled (Actionscript I think?), or would this entirely depend on the author's decision to include such code? If it is dependent on the author's inclusion of the code, are there any possible tests I can run to see what methods might be available?

I have a flash application using callbacks to javascript functions (eg. when it receives some data over a socket, it'll call a js script which would change the content of a div according to that given data).
Afaik, there is no actual mutual exclusion in javascript so I'm not sure if I can/need to simulate something like :
[code]...
So, the question is, when are those callbacks called ? Are they simply queued to be executed right after the browser finishes its task or are they triggered randomly ?

I need to have a banner that changes every 5 seconds. Problem is that when I move from page to page it starts at the beginning. If I had a session that recorded each change and that could be read by flash on initialise then this would work. My prefered platform is PHP but can use ASP

-I know one can call javascript functions from as3 using ExternalInterface, but in all the examples I've seen the function has been a standalone function on the page. Can methods on objects (that are on the page) be called. E.g: obj.someFunc() rather than just someFunc()?
-The return value can be stored as well using ExternalInterfaces. Can this return value be a javascript object? If so, its methods be called from it directly?

I have a Panel in my application which contains 2 buttons and 3 canvas components at certain posstions...now I want to store the current state of panel in some file or database...and afterwards I want to load the same panel again in my application when I come back and run the application. I tried to convert whole panel into ByteArray object using its readObject() and writeObject() methods...but when I read the ByteArray and add the panel in my application using addChild() method it doesn't add anything and there was no error or fault...
writeObject creates ByteArray that I am able to print but when i get it back and add child, I am not able to get the panel and it's children.

I've embedded a virtual tour on one of my client sites.
The site is hosted by Slicehost, and as you can see the load times for the Flash movies are very slow, so my idea was to serve the swf files from Amazon S3 Europe.
To test it, I have all swfs uploaded to the same directory / bucket on Amazon, while the index.html and p2q_embed_object.js files reside on my local machine. The js file is changed to refer to the Amazon-hosted swfs. The first swf loads fine, but the others don't. What am I doing wrong? Is there a better way to do this that would allow me to serve my Flash assets from elsewhere?

I am using a embeddable Flash based MP3 player (The standalone Version of Wordpress Audio Player, to be exact) to play audio on the web page of a client. Given the nature of Flash based players - AFAIK they all use Flash's audio/video decoding libraries - the exact player product might not matter, though. She complains that some specific audio files sometimes tend to play slowly, as if on a tape deck that doesn't run at full speed. Her machine is a 5 year old Sony Vaio with a 1.5 GhZ Pentium M Processor.
So it's not top of the line anymore but it should not have trouble decoding anything, let alone a MP3 audio stream. I can't verify the problem because we can't set up an audio connection (slow Internet on a remote island), nor can I reproduce it on my 3.3 GhZ dual-code Workstation, but this is a person whose error reports have seldom turned out unfounded in the past, so I tend to take them seriously. I see differences between the encodings of the MP3 files (see below). Any pointers towards which setting(s) to change?
This is what Winamp tells me about a file that is sometimes slow:
MPEG-1 Layer 3
128 Kbit, approx. 966 frames
48000Hz Stereo
CRC: Yes, Copyright: No
This is what Winamp tells me about a file that is never slow:
Encoder delay: 576, Zero Padding: 1584
MPEG-1 Layer 3
151 Kbit (VBR), 12405 Frames
44100Hz Joint Stereo
CRC: No, Copyright: No

I use javascript to play a flash file, and it plays correctly. But it also needs to parse some configuration files in the flash default directory. So the problem is: the flash file I am going to play can't access its config file for the wrong working directory.
For example, I specify the swf path value as 'falsh/list/test.swf', so my javascript will give this swf value by swfobject.embedSWF to play this flash. But the flash file flash/list/test.swf needs to parse a config file in the same directory with flash file like flash/list/config.xml. The problem is flash attempts to parse this config file under the current javascript working directory.

I'm looking for a Flash video player that is able to stream m4v files on all browsers. Example file: [URL]
Unfortunately, I can't convert the format since it originates from 3rd party servers. I can't rely on HTML5 video since not all browsers support this format and the encoding it contains.
I've already tried several players such as JW Player, Kaltura, Video JS, Projekktor, and more. Testing them with Firefox and IE, some of them couldn't play the m4v file at all, while others downloaded the entire file before starting to play it.

I had a somewhat weird setup for a site here, which goes as follows: Server A holds a SWF Server B holds a HTML document with the SWF Embedded, along with SwfAddress.js I can't seem to get any Flash-to-javascript to work here through External Interface calls. SwfAddress fails and I see this error in Firebugs Console: "Error calling method on NPObject!" This also occurs with another JS function I'm trying to call with the MouseWheel. I've set up my crossdomains and deployed all Security.allowDomain("")'s where applicable. Has anyone embedded an external SWF and had issues with AS-JS communication before??

I generate a HTML page with VB.Net which stores several pinks to files. These links are formatted with JavaScript looking like the Windows-Explorer with folders and files. The problem: There are only download links for the files, not for Folders. A folder can contain Subfolders ,a List of Files or a combination of both. So if I want to download a folder, I have to click manually on every file-link. I have not the possibility to insert PHP or another Server-side language. my question now is: Is there a client side way to Download them by click on a Folder? I prefer Javascript but If it isn't possible Flash will be ok also.

I am looking for a javascript based preloader that can handle .SWF (flash) files. I'm very much aware that it is possible to preload a flash file by using another flash file, but I was wondering if anyone knows about an AJAX preloader that can load swfs (also, a progressEvent would be a nice extra) and then add the flash file to the HTML document. I did quite some googling but it seems that there is no such thing out there. Is it überhaupt possible?

I want my file upload to be very simple, and what could be simpler than just a single button. The requirements are that you should be able to upload multiple files at once. It would definitely be an advantage if I could add file format filters as well, and design the button by myself (including the hover event).
I searched and found Plupload, which seemed to be awesome with the easy setup and functionality, but I can't quite figure out how to create my button; I've only found their Custom upload, which prints out the file names and requires at least one click on another button before it's done (and I can apparently not add any hover-attribute). I tried to edit the JavaScript to make the form be sent after all the files had been added, but failed.

Just put our new site live, and having trouble with one of the swf files playing. Using the colorbox jquery plugin throughout the site and this works fine. However a movie on [URL] (qcf engine movie) gives out a repeated javascript 'Access is denied' error everytime you close the colorbox?? Perhaps because the swf file is hosted on amazon s3, although other movies are playing fine from S3,
Example: [URL]
And the error: [URL]

I'm working on a project that originally required me to use <area> elements and 40 copies of a single GIF image to have a hoverable and clickable <img> tag. I suggested SVG, and the client agreed to use SVG instead, as it was easier to work with for both of us.
Anyways, my question is, what cross-browser JavaScript SVG library will allow me to display and interact with pre-made SVG images.
I know of these libraries:
Raphaël: I'm currently using this along with a SVG loading plugin. But that plugin does not support Inkscape or Adobe Illustrator SVGs (i.e. most SVGs). cang: This library looks promising, but it requires <canvas> support, which IE doesn't have natively. svgweb: Another more-promising library. It requires Flash, but most IE users have Flash. jQuery SVG: It seems to be able to load SVG images, but development seems to have died. And it requires me to use a modified version of jQuery 1.3.
My client would like to provide somewhat-arbitrary images to my script and have chunks of them be "selectable" (see my demo here).

So I'm building a web application, and in part of the application the user should choose an XviD (.avi) video file from his machine, to be played in the browser (without uploading it). I decided to use Flash for this.
Now I have two questions about this:
Which Flash video player is free to use and capable of doing this? How should I let the user choose a video file, and how can I link the Flash video player to the file?

I need to execute some javascript string code from flash swf file using actionscript 3.
I read that it could be done by passing the javascript code to the parent html document , using externalinterface.call function. Then I assume it will be faster if I can declare functions in the javascript code in the HTML document in the first use of externalinterface.call funtion ; if flash code calls the javascript code repeatedly. So let me ask you how to do that. For details , any javascript to be loaded is unknown in design time and I can not prepare a javascript file to be loaded.

Is it possible to pass file names from a running Flash application, which only purpose is to enable multiple-file-selection, to a JavaScript application which handles upload of all files to the server?I have examined various Flash upload solutions (like SWFUpload, Uploadify, etc.) and none of them meets my needs. I want an easy to implement solution (like Uploadify) which also lets me specify various parts of the HTTP request.
The reason I need this is because my upload form uses session cookies (for user authentication) and an CSRF token both passed to the server when uploading files.Is it technically possible to pass filenames (+ paths) to a JavaScript application which then handles the upload?

Here's the challenge: I have a Flash movie which will be embedded in a page using an unknown DOM ID that I want to be able to identify/store for callback in a JS function. My ideal user flow would be: User clicks button in Flash. Flash pauses any animations / video / sounds / etc. Flash calls an injected JS function to display a page-covering overlay experience. When user closes overlay experience, a callback method on the Flash object is called. Flash resumes playback.
The problem is, when AS3 uses the ExternalInterface.call("functionName", args...) method, there doesn't seem to be a DOM event triggered, and thus it is impossible to tell which object called a JS function, so having a "registerMe()" function doesn't seem to work. Basically, the injected JS function has no way to determine which DOM object to call, because the ID of the Flash object is unknown.
