I am working over a program that needs to extract meta data from music files in different formats. It was easy for MP3 format, but there is nothing for other formats.I made a research, there is a lot of software for extracting meta data - but no source code or algorithm. There are open source projects, they use their own libraries, but I was not able to find something for Flex (Action Script)
View 2 RepliesWhat software is available for extracting metadata from an FLV? I'm testing an flv streaming module for apache (mod_flvx) and need to extract keyframe info from an flv for debugging purposes. I was only able to find FLV MetaData Viewer, but its dated, from 2006, and doesn't install properly on Win7. [URL] Edit: I'm open to any method of extraction, either app or library.
View 1 RepliesI'm trying to match the behavior of SoundMixer.computeSpectrum() by using the new Sound.extract() method, so that I can draw music visualizations for separate Sound objects at once. As you know, computeSpectrum() samples the currently playing audio and copies it to a ByteArray. Sound.extract(), on the other hand, copies as much of the Sound as you want to the ByteArray, and does not require the Sound to be playing at the time.
With the Sound data extracted to a ByteArray, I know have about twenty-six thousand floating-point values representing the waveform, from start to finish. However, I'm only interested in about thirty-two of them at a time- the last thirty-two that were played. How do I determine where in the ByteArray that would be?

I´m playing around with SWF files exported from indesign CS4. I wonder if there is a way to read any metadata from those files. Or is there any? I have not found any AS3 method to trace metadata like time/date or even some unique ID...something that I could use later to specify that file.
View 4 RepliesWhat I want to do is to extract a zip file to a specific folder.I am using the code below that promts the user to choose which directory the zip should be extracted to and the extracts it succesfully.Now I would like define a fixed folder where the files should be axtracted to instead of letting the user decide.
Actionscript Code:
function extractZIP():void { output.text = "extractZIP MANUAL"; zipOutput.browseForDirectory("Select Directory for extract");
[code].......
This hopefully should be an easy fix. Part of my program calls for extracting the number of files within a given directory. This is done easily using the code below:

However, this code only works using AIR as the runtime player. There should be an equivalent command that can be used with Flash layer 10.2 or earlier.
I want to create animations in flash, and then export a sprite sheet with the sprites and a xml(or another format) with information about how to "cut" and move the sprites.
I don't know where to start, use some library for reading swf in c# or java? try to export using AS3 inside the swf?
I'm creating a simple online, Flash-based music player; the user clicks on a song in a DataGrid and then it plays, simple. I will display the song information with the ID3 method in the 'sound' class, but I don't want to hard-code all the songs into the ActionScript, because I might change them. I have created a "tracks" folder in the site directory; how can I extract the names of the files within that folder without knowing how many files there are, and inherently, without knowing the URLs?
View 4 Repliesoverriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?
I am working on a photo gallery with music and everything works good except I can not seem to load multiple music files one right after another. This is the code I have that works with one music file.
View 1 RepliesAlright so I'm making a website for my friends band, and they want to have a music player to play their MP3's. One of the things I'm concerned about though, is the security of the MP3 files. Their albums are on iTunes to buy, so I'm looking for what the best option to have the MP3s be played but not be able to be downloaded and saved.The best thing I can think of is embedding the MP3's inside a Flash music player, but that would be more work than it's worth it seems.

Code:

I know that it is possible to add swf metadata to the compile command as a command option, but I can't find any documentation on how to access these metadata within the actionscript during runtime. We're trying to add a version number to the swf during compile time and then somewhere in our app we would retrieve it during runtime, here is the command example to add the description metadata.
mxmlc -description "version 1.2.3"
I know the swf metadata is used by search engines and other utilities to gather information about the SWF file, but surely you should be able to retrieve them in the actionscript during runtime?
I'm trying to embed a font in Flex and the code I'm using looks the same as the example, but throws an error. This is the code I've written:
[Embed(source="data/posca_mad_thrasherz/posca_mad_thrasherz.ttf",
fontName = "fontGraffiti",
fontWeight = "bold",
mimeType="application/x-font")];
private var funFont:Class;
But I get the error, "Metadata requires an associated definition." I can't seem to get rid of it.
I have a situation where a simple query against a table is returning incorrect values in Flex, but not in other GUI front-ends to SQLite.
select title from ttl where ttl.ttl = 140 // ttl is also the column name of the PK column
is returning the title that belongs to the row whose PK = 1400.
ttl.ttl is defined as int datatype.
Again, the problem manifests itself only in Flex, not in other GUI front-ends to SQLite, which are returning the correct title value.
I saw that you can embed meta-data into images very much like you can in mp3s, here.
Can someone point me to a tutorial of how to embed and read this sort of information w/ photoshop and flex together? I really wouldn't know where to start... Tried googling but I'm not sure I have the right keywords down.
I have something like
public class Controller {
[Observer("fetchEmployeesEvent")]
public function fetchEmployees() : void {

What language construction can be used to make a compile time checking of Array elements type when the Array is a function parameter?[code]Here we've marked the returned Array as one containing elements of type string.Is there a way to mark the parameter variable as an Array containing elements of certain type?I'm specially interested in the Array collection. I'm aware of the vector collection but I have reasons not to use it in my case.

When I use

[Code]...
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)

MMO best practice. Download music and heavy files to users hard disk? I have just downloaded a Hello Kitty MMO app for research (for my kid of course).I am developping my English teaching app with LOADS of classical music, mp3 sentences and heavy background bgs. Would the best idea be for client to download these to their hardisk ie I would not need to stream them and therefore save a fortune on bandwidth charges from my ISP?
View 3 RepliesI was trying to make a media player with AS3 coding.. I know how to make play, pause, next buttons etc.. And i also learned to load playlist from a XML file (created mannually)..What i actually need is to browse the computer and select multiple files and add those files to a playlist.. All these must be done with the media player itself(not manually typing the XML data).. XML file dynamically by selecting the music files, using the player.. Or is there some other method to create playlist without making the XML?..

View 1 RepliesI'm using an auto complete component and a labelFunction so that user have the ability to search by their name or id. Once the search is completed I'd like to extract the data to a query.
The only problem is that I only need the name or id for the query not both, so I'd like to pull from just the id variable...
Currently if the user types - Joe or if they type - 13
Both would return a result of Joe - 13 via the auto complete component.
