&lt;!-- End of automatically inserted text --&gt;

I am making a flash app that demonstrates potensial traffic injuries when driving at different speeds. I want the user to be able to share this information on facebook. However this demands that i can customize the text that will appear on facebook in some manner.

I am making an url that is opened in a blank window (from the flash app itself). I specify the u and t parameters, putting the generated message as the t parameter. But this seems to always be overridden by the pages title. If i omit the title tag from the html code, the file name is used (also overriding the specified title).
&lt;pre&gt;
http://www.facebook.com/sharer.php?u=http://espentokerud.com/face/addiste.html&amp;t=test;
&lt;/pre&gt;
I also tried url-encoding the url, but to no avail.
&lt;pre&gt;
http://www.facebook.com/sharer.php?u=http%3a%2f%2fespentokerud.com%2fface%2faddiste.html&amp;t=test;
&lt;/pre&gt;
I also tried using the addthis API, but experience the same shortcomings. The funny thing is that if i post a swf, the title and description can be customized, and it is also possible to specify a screenshot. But if i dont post a swf, this seems to be ignored.

I am aware that I can use meta tags on the html page to specify the thumbnail image, title and description, but some of this content has to be based on calculations inside the flash app. 




Want custom title / image / description in facebook share link from a flash app

I am currently working on a Flash webplayer with resolution switching functionality. I am trying to make use of the NetStream class&#39;s `play2()` function in Actionscript.

The problem I am running into is that the videos don&#39;t change quickly. For those familiar with the `play2()` function I believe that the player is performing a `&quot;standard switch&quot;` rather than a `&quot;fast switch.&quot;`

[The documentation says that][1] when the offset parameter is -1, fast switching occurs. What actually happens, though is once the `&quot;NetStream.Play.Transition&quot;` event is received, the player waits until the time denoted by `ns.time + ns.bufferLength` has been reached, before performing the switch.

I thought fast switching cleared the buffer, but on a check to `ns.backbufferlength`, I found that everything is still cached. Also it mentions: &quot;When offset is -1, the switch occurs at the first available keyframe after `netstream.time + 3`,&quot; which is why I am confused.

Any help/insight on this matter would be much appreciated.

Here is a snippet of code describing what is going on (`newStream()` is called when a user clicks to change to a new resolution, youtube style):

    public function newStream(address:String):void
    {
        var opts:NetStreamPlayOptions = new NetStreamPlayOptions();
        opts.streamName = address;
        opts.transition = NetStreamPlayTransitions.SWITCH;
        opts.offset = -1;
        ns.play2(opts);
    }

    private function nsCallback(event:NetStatusEvent)
    {
        switch(event.info.code)
        {
            case &quot;NetStream.Play.Transition&quot;:
            {
                trace(&quot;Current time (on Transition): &quot; + 
                      ns.time, &quot;Buffer: &quot; + ns.bufferLength);
                var estTime:Number = ns.time + ns.bufferLength;
                trace(&quot;Estimated Completion Time: &quot; + estTime);
                break;
            }
        }
    }

How to make use of play2() function in order to perform fast stream switching of videos?

I&#39;m trying to assign the output of a command to a variable - as in, I&#39;m trying to set the current flash version to a variable. I know this is wrong, but this is what I&#39;ve tried:

    set var=reg query hklm\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion&gt;

or

    reg query hklm\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion &gt;&gt; set var

Yeah, as you can see I&#39;m a bit lost. Any and all help is appreciated!

I have a website (Flash) localized into a dozen of languages and I want to auto-define a default value depending on the user&#39;s browser settings in order to minimize the steps to access the content.

FYI, I cannot use server scripts due to proxy restrictions, so I guess JavaScript or ActionScript would be appropriate to solve the problem.

**Questions:**

1. What would be the best method to &#39;guess&#39; the user&#39;s locale? 

2. Are there any existing simple classes/functions that could help me out (no complex localization bundles)? Especially to reduce all possible languages to a smaller number (the translations I have) in a smart way.

3. To which point can I trust such a solution?

4. Any other workarounds or suggestions?

How do you embed a SWF file in an HTML page?


How to embed a SWF file in an HTML page?

I have a Flash project, and it has many source files. I have a fairly heavily-used class, call it Jenine. I recently (and, perhaps, callously) relocated Jenine from one namespace to another. I thought we were ready - I thought it was time. The new Jenine was better in every way - she had lost some code bloat, she had decoupled herself from a few vestigial class relationships, and she had finally come home to the namespace that she had always secretly known in her heart was the one she truly belonged to. She was among her own kind.

Unfortunately, Flash would have none of that. Perhaps it had formed an attachment. Perhaps it didn&#39;t _want_ Jenine to be decoupled. Either way, it clung to the old, perfect version of Jenine in its memory. It refused to move on. It ignored her (function) calls. It tried to forget her new, public interfaces. Instead, every instance of Jenine that it constructed was always a copy of the old version, down to its classpath:

    var jenineInstance:Jenine = new Jenine();
    trace( getQualifiedClassName(jenineInstance));
    // Should print: com.newnamespace.subspace::Jenine
    // Prints: com.oldnamespace.subspace::Jenine
    // Ah, young love!

We fought. I&#39;m not proud of some of the things I said or did. In the end, in a towering fit of rage, I deleted all references of Jenine completely. She was utterly, completely erased from the system. My cursor fell upon the &quot;Empty Trash&quot; menu option like the cold lid of a casket.

I don&#39;t think Flash ever recovered. To this day it still clings to the memory of Jenine. Her old, imperfect definitions still float through my project like abandoned ghosts. Whenever I force Flash to compile, it still lovingly inserts her into my movie, nestling her definition in amongst the other, living classes, like a small shrine. I wonder if they can see her.

Flash and I don&#39;t really talk anymore. I write my code, it compiles it. There&#39;s a new girl in town named Summer who looks almost identical to Jenine, as if someone had just copied her source-code wholesale into a new class, but Flash hasn&#39;t shown any interest. Most days it just mopes around and writes bad poetry in my comments when it thinks I&#39;m not looking.

I hope no one else has had a similar experience, that this is just a singular, painful ripple in the horrifying dark lagoon that is the Flash code-base. Does anyone have any idea how to erase whatever cache the compiler is using?


Flash CS4 refuses to let go

A topic of debate that&#39;s seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5.  There are those that suggest that HTML5 will one day supplant/replace Adobe Flash.

*I do not develop software that runs in a browser,* so my (limited) understanding is:

 - HTML is a pure-text markup language that is delivered over HTTP to a client browser.  The client browser interprets the markup and renders (with varying degrees of success) the page according to an standard specification.
 - Adobe Flash is a propriety framework for working with audio, video, sound and raster/vector graphics.  It requires special authoring tools (a compiler perhaps?) and a custom player that&#39;s available as a plug-in to most common browsers.

Could someone please explain (to this C/C++ developer) how it is possible *from a technical/coding point-of-view* that a text-based markup language (HTML5) could be considered a replacement to a multimedia framework (Flash)? 

***Please no opinionated arguments - just technical facts.***


How can HTML5 &quot;replace&quot; Flash?

I&#39;m looking for javascript libraries and code that can simulate `localStorage` on browsers that do not have native support.

Basically, I&#39;d like to code my site using `localStorage` to store data and know that it will still work on browsers that don&#39;t natively support it. This would mean a library would detect if `window.localStorage` exists and use it if it does. If it doesn&#39;t exist, then it would create some sort of fallback method of local storage, by creating its own implementation in the `window.localStorage` namespace.

So far, I&#39;ve found these solutions:

1. Simple [sessionStorage][1] implementation.
2. An implementation [that uses cookies][2] (not thrilled with this idea).
3. Dojo&#39;s [dojox.storage][3], but it is it&#39;s own thing, not really a fallback.

I understand that Flash and Silverlight can be used for local storage as well, but haven&#39;t found anything on using them as a fallback for standard HTML5 localStorage. Perhaps Google Gears has this capability too?

Please share any related libraries, resources, or code snippets that you&#39;ve found! I&#39;d be especially interested in pure javascript or jquery-based solutions, but am guessing that is unlikely.

HTML5 Local Storage fallback solutions

## IMPORTANT UPDATE

This question was made over 9 years ago. It made sense then, it doesn&#39;t make it now. Flash is hard on its way out; `&lt;video&gt;` support is ubiquitous, including mobile devices. Almost anything that Flash could do, HTML can now do too. HTML won, Flash lost. If you&#39;re pondering on how to embed video in your page, just use `&lt;video&gt;` and don&#39;t give it a second thought. This question is only preserved for historical value.

### Original question

Seems like the new `&lt;video&gt;` tag is all the hype these days, especially since Firefox now supports it. News of this are popping up in blogs all over the place, and everyone seems to be excited. But what about?

As much as I searched I could not find anything that would make it better than the good old Flash video. In fact, I see only problems with it:

* It will still be some time before all the browsers start supporting it, and much more time before most people upgrade;
* Flash is available already and everyone has it;
* You can couple Flash with whatever fancy UI you want for controlling the playback. I gather that the &lt;video&gt; tag will be controllable as well (via JavaScript probably), but will it be able to go fullscreen?

The only two pros for a `&lt;video&gt;` tag that I can see are:

* It is more &quot;semantic&quot; - which probably holds no importance to a whole lot of people, including me;
* It is not dependent on a single commercial 3rd party entity (Adobe) - which I also don&#39;t see as a compelling reason to switch, because free players and video converters are already available, and Adobe is not hindering the whole process in any way (it&#39;s not in their interests even).

So... what&#39;s the big deal?

**Added:**

OK, so there is one more Pro... maybe. Support for mobile devices. Hard to say though. A number of thoughts race through my head about the subject:

 * How many mobile devices are actually able to decode video at a decent speed anyway, Flash or otherwise?
 * How long until mainstream mobile devices get the `&lt;video&gt;` support? Even if it is available through updates, how many people actually do that?
 * How many people watch videos on web pages on their mobile phones at all?

As for the semantics part - I understand that search engines might be able to detect videos better now, but... what will they do with them anyway? OK, so they know that there is a video in the page. And? They can&#39;t index a video! I&#39;d like some more arguments here.

**Added:**

Just thought of another Cons. This opens up a whole new area of cross-browser incompatibility. HTML and CSS is quite messy already in this aspect. Flash at least is the same everywhere. But it&#39;s enough for at least one major browser vendor to decide against the `&lt;video&gt;` tag (can anyone say &quot;Internet Explorer&quot;?) and we have a nice new area of hell to explore.

**Added:**

A Pro just came in. More competition = more innovation. That&#39;s true. Giving Adobe more competition will probably force them to improve Flash in areas it has been lacking so far. Linux seems to be a weak spot for it, cited by many.


HTML 5 &lt;video&gt; tag vs Flash video. What are the pros and cons?

I am working on a site that has a ton of embedded youtube videos, the client wants to show a popup whenever a video stops splaying.

I looked at the youtube api and there seems to be a way to detect when a video ends:

http://code.google.com/apis/youtube/js_api_reference.html

but I can&#39;t embed the videos like they mentioned on that page since the videos are all already on the site (thousands that have been added manually by pasting embed code).

Is there a way to detect the ending of these videos without changing any of the existing videos (using javascript)?

How to detect when a youtube video finishes playing?

Does anyone have an example of script that can work reliably well across IE/Firefox to detect if the browser is capable of displaying embedded flash content. I say reliably because I know its not possible 100% of the time. 

Cross Browser Flash Detection in Javascript

Today I checked mega.co.nz and I&#39;m excited about some features. For example in download page it will download files on browser and after that decrypt them with javascript.

for example see this link to download a png file :

[https://mega.co.nz/#!7JRgFJzJ!efpJGWuPhYczLexY19ex82nuwfs4sR_DG4JXddeClH4][1]

  [1]: https://mega.co.nz/#!7JRgFJzJ!efpJGWuPhYczLexY19ex82nuwfs4sR_DG4JXddeClH4

in this link it will start the download inside the browser. i checked network tab in inspect element it will download parts of file with AJAX after that completed all parts of file, will save all of them in one file on computer automatically!

i want to know what they do? can you explain or link to some resource about download files inside browser like that?

also can done it only with javascript or should use some flash plugins or something like that?

I&#39;m trying to figure out a decent solution (especially from the SEO side) for embedding fonts in web pages. So far I have seen [the W3C solution][1], which doesn&#39;t even work on Firefox, and [this pretty cool solution][2]. The second solution is for titles only. Is there a solution available for full text? I&#39;m tired of the standard fonts for web pages.

Thanks!

How to embed fonts in HTML?

Question
--------

Alright, I&#39;m confused by all the buzzwords and press release bingo going on.

  - What is the relationship between flash and flex:
    - Replace flash (not really compatible)
    - Enhance flash
    - The next version of flash but still basically compatible
    - Separate technology altogether
    - ???
  - If I&#39;m starting out in Flash now, should I just skip to Flex?


Follow up
---------

Ok, so what I&#39;m hearing is that there&#39;s three different parts to the puzzle:

  - **Flash**
   - The graphical editor used to make &quot;Flash Movies&quot;, ie it&#39;s an IDE that focuses on the visual aspect of &quot;Flash&quot;  (Officially Flash CS3?)
   - The official name for the display plugins (ie, &quot;Download Flash Now!&quot;)
   - A general reference to the entire technology stack
   - In terms of the editor, it&#39;s a linear timeline based editor, best used for animations with complex interactivity.
  - **Actionscript**
   - The &quot;Flash&quot; programming language
  - **Flex**
   - An Adobe Flash IDE that focuses on the coding/programming aspect of &quot;Flash&quot; (Flex Builder?)
   - A Flash library that enhances Flash and makes it easier to *program* for (Flex SDK?)
   - Is not bound to a timeline (as the Flash IDE is) and so &quot;standard&quot; applications are more easily accomplished.

Is this correct?

What is Adobe Flex? Is it just Flash II?

I&#39;ve been reading that Adobe has made crossdomain.xml stricter in flash 9-10 and I&#39;m wondering of someone can paste me a copy of one that they know works. Having some trouble finding a recent sample on Adobe&#39;s site.

Can someone post a well formed crossdomain.xml sample?

when embedding a Flash object with the `&lt;object&gt;` and `&lt;embed&gt;` tag, there is an attribute called `wmode`. It seems that most of the time, `wmode=&quot;transparent&quot;` is the same as `wmode=&quot;opaque&quot;` as the Flash doesn&#39;t actually have any transparent color so that the bottom HTML element is to be shown.  As a result, `opaque` should be faster than `transparent` since it requires less processing for transparency, yet most of the time i see Flash object embedded with `transparent` instead of `opaque`.

`opaque` is needed so that other HTML element won&#39;t be covered up by the Flash object (such as a menu item that pops up an extra sub-menu won&#39;t be covered up by the Flash object).

By the way, is there formal documentation for `wmode`&#39;s `opaque`, `transparent`, and `window`?  I was only able to find blogs that describe it but not the formal documentation.  thanks.


differences between using wmode=&quot;transparent&quot;, &quot;opaque&quot;, or &quot;window&quot; for an embedded object on a webpage

I have the feeling that [Flash][1]-based ( or [Silverlight][2]-based) websites are generally frowned upon, except when you are creating games or multimedia-content rich applications. Why this is so?

What is so evil about a Flash based website?

My company develops several types of applications.  A lot of our business comes from doing multimedia-type apps, typically done in Flash.  However, now that side of the house is starting to migrate towards doing Flex development.

Most of our other development is done using .NET.  I&#39;m trying to make a push towards doing Silverlight development instead, since it would take better advantage of the .NET developers on staff.  I prefer the Silverlight platform over the Flex platform for the simple fact that Silverlight is all .NET code.  We have more .NET developers on staff than Flash/Flex developers, and most of our Flash/Flex developers are graphic artists (not real programmers).  Only reason they push towards Flex right now is because it seems like the logical step from Flash.

I&#39;ve done development using both, and I honestly believe Silverlight is easier to work with.  But I&#39;m trying to convince people who are only Flash developers. 

So here&#39;s my question:  If I&#39;m going to go into a meeting to praise Silverlight, why would a company want to go with Silverlight instead of Flex?  Other than the obvious &quot;not everyone has Silverlight&quot;, what are the pros and cons for each?

Is it possible to embed a flash video &lt;object&gt; into README.md on GitHub? It isn&#39;t showing up: &lt;https://github.com/mattdipasquale/PicSciP&gt;

How to embed a video into GitHub README.md?

I am encountering some very strange behaviour with a Flex 4.1 app I am writing which gets in the way of testing. It seems that I can reload the app 16 times and then on the 17th, the loading process fails with

    Error #2046: The loaded file did not have a valid signature

It seems to be consistently happening on the 17th reload on both Firefox 5.0 and Chrome 12. I am not sure if it&#39;s relevant, but I am running Flash Player v10.2.159.1 (also happens with 10.3.181.34) on Ubuntu  10.04. Happens with both regular and debugger versions of the player. When I run the app on Windows FF5, it doesn&#39;t seem to happen. Closing the current browser window does not seem to fix it. The only way around it is to completely close all browser windows and restart the browser. And then again after 16 successful loads, the 17th fails.

At this point I&#39;m thinking of chalking it as a Linux Flash bug but I&#39;d like to make sure and check if anyone knows if there&#39;s something I should be doing to prevent this.

The user from [this post][1] seems to have had the same problem but I guess he didn&#39;t notice the pattern I have.

Any help will be greatly appreciated.
Ruy

== UPDATE ==

I just realized that after my app starts throwing the 2046 error, trying to load any other Flash that uses signed RSLs also shows the 2046 error (e.g. [this app][2]), which means the problem is not specific to my app and most likely related to the Flash cache or something of the sort.

In ActionScript 3, using vector graphics is a guaranteed way to cause massive damage to the performance of your project.

Using a single `Bitmap` for all graphics by using [`.copyPixels()`][1] through its `BitmapData` object in place of all vector graphics will yield a ridiculous performance boost and is essential for people like myself developing games within Flash.

Beyond this I&#39;m not really sure what the next major things that I should be targeting and attempting to optimize are. I do use a lot of the inbuilt trigonometry functions, but they don&#39;t seem to affect it all that much. I know there are some libraries that optimize mathematics with approximation methods and similar, but so far I haven&#39;t found these necessary.

Are there any other massive known points I should be looking at? I&#39;m more referring to the inbuilt things that I should be careful of (like avoiding vector rendering) rather than how to improve my own coding style.
