[Flashcoders] load flv and its metadata without start to play
Hello, I want to use video for character animations and so I want to preload several videos without to play them while preloading. How can I do this in AS3? I found only the play(something.flv) method. Are there any other possibilities? Also, I am currently waiting for my metadata handler to be called before I accept a video as loaded, because I need to set its height and width, which only works using these values. video.videoWidth and video.videoHeight doesn't work for me all the time. And because I have more than one charactor of its kind, do I need to load the flv as often as many characters I have? Any suggestions?

Hi,
Steven Sacks posted this the other day.

Preloading FLVs is easy peasy.
var progressTimer:Timer = new Timer(10);
progressTimer.addEventListener(TimerEvent.TIMER, updateProgress);
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
progressTimer.start();
// PLAY IT THEN PAUSE IT
ns.play(path);
ns.pause(true);
private function updateProgress($event:TimerEvent):void
{
dispatchEvent(new ProgressEvent(ProgressEvent.PROGRESS, false,
false, ns.bytesLoaded, ns.bytesTotal));
}
private function onNetStreamStatus($event:NetStatusEvent):void
{
if ($event.info.code == NetStream.Buffer.Flush)
{
progressTimer.stop();
dispatchEvent(new Event(Event.COMPLETE));
}
}

RE: [Flashcoders] Windowing in AIR

The bounds of my app will never confine to my content but only to my canvas. I want my bounds to be smaller accourding to the state of my app. Does that make any sense to you?

Re: [Flashcoders] load flv and its metadata without start to play
Glen, Unfortunately, I discovered a bug with the code I posted. The NetStream.Buffer.Flush does not fire if the NetStream is paused. You have to check to see if the ns.bytesLoaded == ns.bytesTotal in the onProgress. Matthias, I have never had any unwanted sound behavior when I use: ns.play(src); ns.pause(true); If you are hearing an audio blip, it's simple to fix by applying a SoundTransform with the volume set to 0 before you play/pause the NetStream. var transform:SoundTransform = ns.soundTransform; transform.volume = 0; ns.soundTransform = transform; ns.play(src); ns.pause(true); For the sake of this discussion, I'm going to assume we're talking about progressive downloads as opposed to FLVs streamed from FMS. You cannot attach a single NetStream to multiple Video instances. If you fully load an FLV and caching is turned on (never a guarantee, but likely) then the FLV will load instantly for the next NetStream that loads it. HOWEVER, if it is not cached and you start a second NetStream to load the same FLV before it is finished loading, it will load the entire file again since it's technically not cached according to the browser. I disagree that waiting for metadata is really ugly. How is any client, Flash or otherwise, supposed to know anything about a file it's loading before it starts loading it? The only way it could is if you hard-code it ahead of time because you know what it is. If you're waiting for Flash to determine it dynamically, it has to access the file to get the header information (metadata) that describes the FLV. Because you can play/pause, the metadata can come before you even addChild() the video to the display stack. I don't see how any of this could be considered really ugly but if you do end up writing a psychic script that can determine a file's header data without ever accessing the file, be sure to let us know. ;) The ByteArray idea might work, I've never tried it, and it would probably take you anywhere from 5-15 minutes to try it out. I'm not sure what benefit it would provide you other than guaranteeing that it would be stored in memory if browser cache was turned off. At best, you might get a few milliseconds faster start-up loading from a ByteArray vs from cache.

Re: [Flashcoders] load flv and its metadata without start to play
Hello Steven, yes, I noticed that. I am waiting for ns.bytesLoaded == ns.bytesTotal, and I wait even until metadata are received, as mentioned earlier. I have shut off the unwanted sound behavior now, but don't know, how I did it. pause(false) ist AS2, Steven? AS3/FlexBuilder doesn't allow me to have parameters for ns.pause(). Sure, we talk about flv from file and ns.play(urlToFile). I changed ns.bufferTime to a higher value, now. That's everything I changed lately, and waiting for metadata seems to become faster (can't explain). I know, that it'll take time to load the header/metadata portion of a flv, Steven, but it felt to long. Now, with bigger buffer time (sounds crazy, I know) it is much faster. I'll try the ByteArray idea... Regards, Matthias On Jan 21, 2008 12:07 PM, Steven Sacks [EMAIL PROTECTED] wrote: Glen, Unfortunately, I discovered a bug with the code I posted.

[Flashcoders] MultiLanguage
I may be doing an app that has to be deployed in various languages, and I'm trying to find a good method of doing it. I guess my main issue is that the interface is Flash, and would be created by a designer. Content is pretty much all external, but things like button text, tool tip text, etc. are put in place by the designer. I'd thought of just making different interface 'shells' for the various languages, but that'd be more difficult to maintain. What'd be perfect is language plugins but then I'm not quite sure on how to handle sizing problems - especially with certain languages like chinese. Just looking for some guidance.

Hi, Look at using the Strings Panel - it's in FL8, probably in CS3. This lets you attach an ID to all your text fields, etc. and define languages in XML. The help has more in depth stuff about this, but that is a good start.

Re: [Flashcoders] MultiLanguage
Right, thanks. I realize that, my concern is still sizing issues though. This will be an app that is 'pretty' it has nice looking buttons and such. If everything could be scrollable text fields I would have no problem. Consider something as something as simple as 'stop', which is something like 'anschlag' in german. Doubling the character count in a field can make a big diff for formatting...

Re: [Flashcoders] MultiLanguage
I agree with Glen on the stringpanel part. I've done a big project in the past with multilanguage games.. stringpanel is a good start.. although if you want to give the user the possibility to select the language at runtime you had to code that yourself into the panel.. (that was made back in flash 7 though.. might be in there right now) .. Translating it on forhand isn't always an option.. somtimes the product gets popular and a new country/language is added.. The way we did it is to keep space for larger languages in the design.. and if it isn't possible to translate it shorter.. it will always be a pain in the @ss.. but there should be a balance to keep the designer/design happy and the translations/translators good.. We made an extra panel to add character sets to all textfields on the press of a button.. this way it is easier to add a new character set. Hope this helps..

[Flashcoders] AS3 addChild() strange behaviour
Hi Guys, I have run into a strange problem and its seriously affecting my deadline, i just cant seem to find the problem. - I am using PureMVC and as3. - I am building a dynamic menu based on XML returned from the server - I am attaching MovieClips from the flash IDE library dynamically - Some of these Library MovieClips contain small amounts of code (rollovers, stop() commands etc) If i simply build the menu and do not request the XML the menu appears fine at the actionscript inside the MenuItemMC works as expected. If i invoke my HTTPService to request the XML, and fire a PureMVC sendNotification() when the data is returned and then call buildMenuItems()... the actionscript inside the MenuItemMC is ignored. Has anyone else seen this problem where MovieClips added using addChild() appear to ignore their timeline scripts? -- Regards, Toby de Havilland. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] AS3 addChild() strange behaviour
yes, I have seen problems like these a lot, lately. Do you gotoAndStop/gotoAndPlay on the timeline? If so, your timeline does not execute their script as expected? Timelines are very different in their behavior from AS2 based timelines. So for example a dynamic textField with the same instance name given in the Flash IDE but in different keyframes on the same timeline, is not initialized after a gotoAndStop to that keyframe. It also losses their dynamically assigned text value and so on... AFAIK there are only workaround to this problem. You can wait for that frame to be initialized. An elegant way to do so is to use addFrameScript. But perhaps you have a different problem, which relates to pureMVC or the like. hth, Matthias On Jan 21, 2008 4:23 PM, Toby de Havilland [EMAIL PROTECTED] wrote: Hi Guys, I have run into a strange problem and its seriously affecting my deadline, i just cant seem to find the problem. - I am using PureMVC and as3. - I am building a dynamic menu based on XML returned from the server - I am attaching MovieClips from the flash IDE library dynamically - Some of these Library MovieClips contain small amounts of code (rollovers, stop() commands etc) If i simply build the menu and do not request the XML the menu appears fine at the actionscript inside the MenuItemMC works as expected.

Re: [Flashcoders] load flv and its metadata without start to play
Steven,
I can't figure out a way to use ByteArray. I am able to load the flv
as ByteArray, but I can't see a way to load this into a Netstream
object. Any thought on that?
private function load(url:String):void
{
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE,completeHandler);
loader.addEventListener(IOErrorEvent.IO_ERROR,errorHandler);
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR,errorHandler);
loader.dataFormat = URLLoaderDataFormat.BINARY;
loader.load(new URLRequest(url));
}
private function completeHandler(e:Event):void
{
var loader:URLLoader = e.target as URLLoader;
trace(loader.data); // :-) how to go on from here?
}

If you are hearing an audio blip, it's simple to fix by applying a
SoundTransform with the volume set to 0 before you play/pause the NetStream.
var transform:SoundTransform = ns.soundTransform;
transform.volume = 0;
ns.soundTransform = transform;
ns.play(src);
ns.pause(true);
For the sake of this discussion, I'm going to assume we're talking about
progressive downloads as opposed to FLVs streamed from FMS.
You cannot attach a single NetStream to multiple Video instances.
If you fully load an FLV and caching is turned on (never a guarantee,
but likely) then the FLV will load instantly for the next NetStream that
loads it. HOWEVER, if it is not cached and you start a second NetStream
to load the same FLV before it is finished loading, it will load the
entire file again since it's technically not cached according to the
browser.
I disagree that waiting for metadata is really ugly. How is any
client, Flash or otherwise, supposed to know anything about a file it's
loading before it starts loading it? The only way it could is if you
hard-code it ahead of time because you know what it is.
If you're waiting for Flash to determine it dynamically, it has to
access the file to get the header information (metadata) that describes
the FLV. Because you can play/pause, the metadata can come before you
even addChild() the video to the display stack.
I don't see how any of this could be considered really ugly but if you
do end up writing a psychic script that can determine a file's header
data without ever accessing the file, be sure to let us know. ;)
The ByteArray idea might work, I've never tried it, and it would
probably take you anywhere from 5-15 minutes to try it out. I'm not
sure what benefit it would provide you other than guaranteeing that it
would be stored in memory if browser cache was turned off. At best, you
might get a few milliseconds faster start-up loading from a ByteArray vs
from cache.

c) how to set the video to the real size? I always need to wait for

Any thoughts?
Is it perhaps possible to load the FLV as ByteArray and later load the

Thanks for all the suggestions. I have thought of Flex, but have not used before, so I wouldn't feel comfortable. I like the idea of just leaving room in the design.

RE: [Flashcoders] MultiLanguage
Dave I've lost count of the number of apps like this we've worked on. There are several issues here to address that are wider reaching than just TextFormatting. Firstly you need to think about the character sets each of the various versions will need for deployment. Are all of your required versions only going to require Latin characters ? What about Crylic and other more complicated requirements ? Your choice of typeface (and available character sets) will could be limiting unless you plan carefully. After all there's no point over-weighting a .swf file with characters your not going to use. Look at shared fonts as your best solution to this. By loading an external .SWF file with the required font, and/or font nodes you can dynamically change the display at run-time, negating the need to re-compile the file for each version. From the storage of content - I'd always recommend to run with XML. Makes it soo much easier to change elements at runtime than the flash panel which relies on the end user being able to re-compile the flash. In terms of the language variations affecting design - this one ultimately comes down to educating the creative to design/produce a framework which allows for flexibility. If you need customised 'pretty' buttons then build them as extensions of the components (or custom ones from scratch) that will automatically size where needed. Pete -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dave Mennenoh Sent: 21 January 2008 13:00 To: Flash Coders List Subject: Re: [Flashcoders] MultiLanguage Right, thanks. I realize that, my concern is still sizing issues though. This will be an app that is 'pretty' it has nice looking buttons and such. If everything could be scrollable text fields I would have no problem. Consider something as something as simple as 'stop', which is something like 'anschlag' in german.

For example I want to load 300 graphics to cache while the first section of my movie is playing (rather than preaload them all and make the user wait long).

Re: [Flashcoders] Recommendations to access cache
Yes, if you Preload your stuff will go into the cache whatever algorithm you use to preload them. You can use LiveHTTPHeaders for Firefox or some kind of network debugger like Charles to see what happens when elements are requested. If they are requested and cached, you will see lots of HTTP 304 responses for various requests from the server meaning that the item has not been modified on the server so it will be loaded from the cache. Then clear your cache and do the same again, you will probably get lots ot HTTP 200 responses for the same files as it downloads them again. You can preload everything at the start, or do it behind the scenes, which I try to do.

Re: [Flashcoders] Recommendations to access cache
When loading elements to the cache.. how can we ensure that when we try to access the same element later during the life of an application that the same element will be accessed from cache rather than re-loading the same file? You can't. You can keep it in memory as long as the movie plays, but you can't rely on the browser cache. The user might even have turned cache off. An alternative could be using a local SharedObject. It's not 100% reliable, either, but at least you know when it fails.
