It uses bitmap data to draw each frame of the video, which is streamed using the netstream class. My question is - how can I optimise the speed at which it plays? It plays fine when the stage is small, but when on full screen it starts to get jerky.
I am working on an app that will take a snapshot of an rtmp stream of an archived video, save it to a file, and ExternalInterface the file name to the hosting page to javascript it up for display.
I actually have all pieces working great. The only time an error is thrown is when I pause the video, seek to somewhere, and then try to take a snapshot. Then there is a runtime error of:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: mySwf.swf cannot access rtmp://myFlashServer/myApp. No policy files granted access.I've seen post after post of suggestions and have tried them, but without success.
I have the crossdomain.xml and my FlashMediaServer security setup fine (it is actually working, except for this one glitch). It just seems to be the pause-then-seek-then-BitMapData.draw() combination which is creating issues.
Another weird thing: after the error is thrown, if I resume the stream and take a snapshot, it works flawlessly again.
A webcam feed is published to a Flash Media Server. Now I want the Augmented Reality layer to be a part of this video capture, rendered into one NetStream.
Has anyone done something like adding a watermark to a NetStream before?
I am using NetStream.appendBytes() to play a local video (no server involved) in Adobe AIR. I would like to use BitmapData.draw() to take a picture of the video output, but I am getting this error:
Error #2123: Security sandbox violation: BitmapData.draw: cannot access null. No policy files granted access.
Here is some sample code:
package
{
import flash.display.Sprite;
import flash.filesystem.File;
[Code].....
This is only sample code use for an explanation. The error would happen when calling the getImage method while the video is playing. The error mentions a policy file not found. Since the file is loaded locally there isn't really a place to put a policy file. Is there a policy setting somewhere that needs to be set or is the BitmapData.draw feature just not available when using appendBytes?

I'm making a small video players in AS3, and I've found that after calling NetStream.pause() or NetStream.togglePause(), no status messages are being fired any more.If I click the "pause" button while the video is buffering, I never get the Buffer.Full message.Here is some code:

I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

I've made a mobile version of my software, with low-res images and such, and I can now fully buffer all my content (including a 360 frame animation which is buffered to memory). Problem is, that everytime I update the view, more memory is used.When I write image = new BitmapData();, does it store the previously created BitmapData's in memory? Do I have to flush the memory somehow before I draw my second picture in BitmapData?Example:

I am having an issue with using BitmapData.draw(stage). I am getting the following error:

View 3 RepliesI have an as3 app which utilises an sqlite db to save metrics data. It is well known that as3 is single threaded, so when I save to this db, the Stage Video I am playing becomes jumpy! I have heard that saving db data in batches can speed up this process so I save in a loop:

It seems to me everytime I export a PSD design into flash the images come out a little pixelated. Granted I do use 72 dpi though I thought that was the webstandard. By using flash can I use higher dpi images? Or is there another method I should be using instead of the direct import to lirbary?

View 2 RepliesI have created a X-mas card for my company. When the card opens, the 3 circles are buttons to different scenes within Flash. The text in the bottom left is a button to the final scene.
The card can be viewed here: [URL]
1) When I click on the circle button that has the red garland and tree ornaments in it, if you listen close at the very beginning of the scene, a squeek sound plays. I use this squek sound in the hamster wheel movie symbol used in other scenes, but not in this scene. I don't even have the sound in this scene of the Flash project anywhere. I can not figure out where it is coming from.
2) Does anyone have some optimization tips? My project file is huge and a lot of the people we will be sending this out to probably don't have the most up-to-date processers. Should I split each scene into it's own Flash movie that is only loaded when the button for that scene is selected instead of the whole thing loading?
Here is a link to view the .FLA file: [URL]
I'm working on a flash website that consists of 3 frames (1 = preloader, 2 = instances of symbols, 3 = the main page/view). I've gone through and optimized all my static bitmaps/movieClips and removed any symbol that I've exported for ActionScript from exporting in the first frame. Even after all these steps frame one is still the longest to load (797kb on a 32.6 kbps simulated download), only showing the preloader when the whole file is at 86% complete. Any further steps to take to get frame one's size down?

View 4 RepliesI've got this simple GUI that has a search box and a couple result fields for "Word" and "Definition"...I've also got an XML file with about 800 or so terms and definitions.Currently the flash works just fine, it reads in the XML glossary, splits it into a word array and definition array and when I search through it, it creates a List filled with terms that match the string that I search for. We wanted it to update the list of possible matching terms each time you changed the search term: a, ap, app, appl, apple... etc.
Everything works, its just incredibly slow when you throw 800 terms at it to search through.I was wondering if anyone could either optimize my search somehow, show me another way of doing it.Here is the code pulled from the whole GUI.

My app draws a handful of very large Shapes to the screen very frequently. I've already implemented some logic to reduce that frequency in certain situations, but I'm wondering whether there is anything else I can do.My Shapes' graphics are basically rectangles with BitmapData fills. (Smoothing's turned off.) I can use some simple logic to find the regions where their boundary rectangles intersect the Stage. If I redraw my Shapes' graphics so that they only draw to those intersections, will my app take less time to render?
