ActionScript 3.0 :: Loading Large Content Asynchronously
Aug 20, 2010
I have made an application which loads large pictures and videos (1920*1080 px).
- Picture component is a swf movie that I load with a Loader and feed him with the path of the picture I need
- Video component is a custom actionscript class that uses Video class.
Before to create any of these components, I display an animated sprite (a wheel to suggest a current loading). Then I create this component and load the content. When the content is loaded, then I add it to the display list and remove the wheel sprite.As these actions take a while, the wheel is visible for 1 to 2 seconds. My problem is that during this loading operation (by a Loader or Instantiation), the animated Sprite is not running properly and smoothly, like if Flash was loading the pictures and videos synchronously.Is there a way to make an animated sprite running properly while I am loading a swf or loading a video through the instantiation of a class, means running something asynchronously?
I am trying to write a class, which loads multiple images asynchronously. Can anyone help me to write a image loader class which loads multiple images. My doubt is that do i need to create different instances for Loader and URLRequest for each images? How this is managing efficiently.
I have a full flash site which uses swfobject to embed it 100% height and width. I'm using swffit to force a browser scroll bar for pages with a large amount of content. This is all fine and works perfectly. I also have the content in HTML format, as alternative content and this also works apart from in order to get the flash swfobject to work I need to add the overflow = hidden in the CSS, like:
I'm loading one SWF into another but the internal one is coming over the main content and that can't happen.here is the part of my code where the external content is being loaded anyone hason what I can do to fix this? here is my code:
Code: var loadAnimBox:Loader = new Loader(); var vid_mc:MovieClip;
I have a menu whee you can choose a picture to lead, works great with first selection, but when you choose a different picture it loads over the last picture,I want to substitute the content of that movie clip not to load all the pictures in the same space. I treid to use clear() and removeChild(), but this only works when I choose pic1 then remove that to load pic2, is there an easy way to substitute the content for the new content?
how to load external swfs into the an MC content box using movies with embedded buttons?the problem i'm running into is this: i have animated buttons within movie clips. i also have a main_content MC in my scene into which i'm trying to load background images from another file. this other file has 3 frames, each with a different image.i don't know what the action script would be for a movie/button to load my external swf frames into the main_content MC.
I have a large ON2 VP6 encoded FLV video (334 MB, 75 minutes) hosted on the web and being played back using a basic Flash movie player:
[URL]
Many people are having problems getting the entire video to load. The loading progress bar will increase quite quickly at first, but then it will either slow down to a crawl or will stop completely. If the progress bar stops increasing before the video has fully loaded, it will not continue no matter how long you wait. Reloading the page does help.
Is this likely to be a problem with the FLV file, the Flash player or is it more likely to be a problem with our web host?
Loading takes too long time. Maybe there are some workarounds to make it load at least a bit faster. There is a way of creating static XML - it means splitting existing database records in one, and new records - to dynamic XML (so it's not requesting all Mysql rows in every single page request), but I'm not sure if it's going to make it load fasterWhen loading XML some browsers stop at apprx. 70% and does nothing. (can't figure this one out)
I'm starting a project that will build a flash file with quite complex capabilities. I expect the size of the swf/swc files will be quite big. In order not to slow down the page download, can I build the swf file so only immediately needed components are loaded with the page and other later-stage components can be silently loaded in the background?
I have a Flash application that exchanges data with php scripts. Problem is, I can SEND updates, not receive.Example:
- user drags an object to another area - flash sends this action to a php script using URLLoader - the server acknowledges the action and returns an "ok" message with the same URLLoader
Now if the server wants to send a message, like "there's an update available", or "your friend has logged in", how is this supposed to happen?I believe an always-open socket is out of question, because the server will have to handle too many users at once and the section might be indefinitely long. I'm not so sure about the Flash client constantly pinging the server.So, what's the best way to send data from PHP to Flash asynchronously?
I have this code which works fine when selecting a small number of images.
public var fileReferenceList:FileReferenceList; public function browseFiles(event:Event = null):void {
[Code]....
However, when selecting a large number of images (1000+), the fileList isn't initialized yet when the SELECT event is dispatched. Is there a way to wait for the fileList to be initialized?
I have an Mp3 which is approx 100mb on my server how can i load only small segments at a time so that when people listen to the mp3 it not downloading the full 100mb mp3 file all the time
i am using streaming mode, here some of my code i am using the loadsound command
I'm having a problem loading a 3900 x 5300 PNG file into a movie clip. Is there a limit to the image dimension? When I tried loading smaller png files, it works.
I'm building a flash based site for my photography in Flash CS3 with actionscript 2. The swf is almost 700kb so I guess I'll need a preloader right? I thought I could create a preloader scene before the main content scene and apply the following code to the single frame within the preloader: Code: ifFrameLoaded ("website", 3){ gotoAndPlay ("website", 1); } This doesn't seem to work as the large images in my gallery (contained within a movie clip) won't load unless you leave the gallery page then go back in?
I have a flex application that shows information gathered from different external services by using rest api. Some of them are resource intensive, take longer to response.
I am loading the swf of this scroll bar into my main project using a button. How do I make a large version of the thumbnail load above the scroll bar?
Here is the code that is on the main timeline: //Import TweenMaximport com.greensock.*; //Save the horizontal centervar centerX:Number = stage.stageWidth / 2; //Save the width of the whole galleryvar galleryWidth:Number = infiniteGallery.width; //Speed of the movement (calculated by the mouse position in the moveGallery() function)var speed:Number = 0; [Code] .....
For video playing I used as3 sample script (because there must be only playpause, replay, mute buttons with custom styles), like that
var strSource:String = "video.flv"; // create a new net connection, add event listener and connect // to null because we don't have a media server
[Code]....
The problem is that I can't find a way to play it smoothly. It's loading in very annoying way, video is interrupted after each few seconds of playing.
I understand that the main problem is large video file size and hd quality, but may be there is some way to largely decrease .flv size or handle playback in more friendly way?
At the moment, I am loading an external SWF file into my movie. The swf file contains a large FLV video... At the moment, I am using the code below, and the video is being loaded into a movie clip with the label "vid1"
_root.vid1.loadMovie("womanonbike4.swf");
The video loads fine. However, because it is such a large video, there is a delay. Can I PRELOAD the video during the main movie's Preloader?
So, my main movie starts, a preloader loads the entire main movie AND the external SWF file (womanonbike4.swf). Then, when the movie gets to the part of the main movie, where the external file is loaded, it will just play!
What is the best way to work large amounts of external data in Flash? XML, remoting,something else??I'm looking into a project that has a lot and I'm not sure what the best way to handle it would be
I need to load a dictionary into a game I'm making. It resides in a very large (on the order of 2.81 MB) XML file. While trying to load it, I get an error stating that the script has run for more than 15 seconds. Is there any way I can change the default timeout to allow the file to load?
I have recently "inherited" several websites that feature 1 to 10 minute video animations in SWF formatOne of my challenges is to get these files to appear or play in a timely manner so that the viewer does not loss interest as it is loading. My questions will start with file size.reduce or minimize the size of published SWF files while still maintaining high quality video output? Second, how about this business of preloading.I don't really understand that term but my thinking is that if a large movie could be loading while another, shorter, movie is playing, or a graphic displaying, that this could be useful in my case. Lastly, how about streaming in general. Are there ways to optimally use a given download speed to efficiently stream SWF video?
I have a photo gallery that is XML based. In IE everything works fine. In Firefox, the gallery will load all the thumbnails and then hang up when loading the large image. The trouble is this only happens on the galleries that have a lot of images in them. It works fine with smaller galleries. Since it's xml driven, the images are not loaded until called for and all the thumbnails get loaded. I did see a post about a var being collected for garbage if it's defined inside a function, but I've tried to limit that to just declaring a new image to be displayed. My site is: [URL]. If for some reason you get a page saying that this site is under construction, click the link to the gallery again. I don't know why that keeps bringing up an old page.
I'm trying to load a local file using FileReference load(). It will load small files just fine, but when I try to load a file of around 4-80 megabytes the flash player will crash. I read the load method officially supports up to 100 megabytes.
Here is the exact class I'm using to test: ActionScript Code: import flash.events.Event; import flash.events.IOErrorEvent; import flash.events.ProgressEvent; import flash.net.FileReference; import flash.net.FileFilter [Code] .....
I have a flex application that repeatedly polls a remote XML file to detect changes, but I've found that once the file hits a certain size, the poll blocks the UI and makes the page unresponsive for a short time.
Is there any way to ensure that the call made to the server or the event from the flash.utils.Timer class runs asynchronously to the main UI thread?
I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.
I am adding data inside a VGroup dynamically using Action Script. Each data is an instance of a custom component. So when the number of item is more, It take time to load, which look bad.
Is there any way, we can load data to it, asynchronously or is there any way, so that more data can be added inside a scroller only when the scroll bar reaches to the end ( as it happens in Android or IPhone).?
Is it possible to delegate heavy computations to be handled asynchronously (on the user's machine)? When it's done, I could just fire an event, catch the new data, and update. I have played with this for lesser operations, by just setting up a que and only handle a few operations per frame; but is there another method? That feels like a heavy handed workaround, and it won't scale with faster/slower machines. IE: 12 operations per frame works fine on the test machine, but my machine can handle more, but won't do it because it's hard coded.
With AS3 and the loader class and all of that, what's the consensus on best method for loading big SWFs? I looked on the forum and saw a mix of either using the loader class and making one multi-frame swf or using a loader swf and a separate content swf.
