ActionScript 3.0 :: Way Of Getting Total Duration Of An Flv File Without Using Metadata Event?
Nov 15, 2006
LI am making a custom video player with FLVPlay back controlls. I am using custom progress bar. I am using "MetadataEvent.METADATA_RECEIVED" to get the duration of the uploaded flv file. It works in most of the cases but not in all. Therefore I am asking for anyalternative procedure that can provide the total flv file duration. I don't know even is it possible or not. I am familiarwith AS2 but new to AS3, so

I am using Flash Media Server 3 hosted by Influxis.I use to upload flash videos (flv) to view from our company website, which uses Flowplayer.I got a new video which is F4V, but this video is little wierd, It plays well but the duration shows as 3:00:00 (3 hours) which is actually 11minutes 30 seconds.

I can find the duration of an external video to be played in my flash presentation?I am loading it to stage using netConnection/netStream.I have found information about the "time" property which tells me at what point the playhead is, but how can I get the total playback time?

I'm creating a video player in an environment where stream.bytesTotal isn't available. I need to use the duration metadata encoded in flv files to extrapolate for things such as the play progress, and the time display.
The problem is when loading an flv the metadata, including the duration, fails to be accessed 2 out of 3 times. Here is the function that iterates through the metadata object

I have over 1200 videos in our catalog that were somehow transcoded with a missing duration, assigning it a value of 0 - the data rate is also 0. How do I determine the video duration by another means, with just the .flv file as a resource.

I have a FLV player using netstream. I am using metaData to grab the video duration and time. It will grab the total duration time, but I want it to countdown to zero, like iTunes. Basically, the time will play and the duration will countdown to zero at the end of the video. I thought that I could take (duration) - (time played) but it's not working.

I have a video object attached to my flash and I want to display a time readout of how far into the video has been played. I know I need a dynamic text field, but I cannot find any methods of the NetStream that gets the total duration.

I'm streaming live video through FMS 3 and passing the streams to another FMS application to be recorded. While recording, I inject some custom metadata into the stream. Once recording is finished, I move the flv to another location and update my database with the metadata contained in the stream for later reference. All this succeeds without a problem.
However, only sometimes, the default 'duration' metadata (note - I never mess with the duration metadata, merely insert my own fields that are required for other reasons) is COMPLETELY wrong

I need this to work so that on my stage i can have a dynamic text box displaying the current time of the flv and the total time ---- example 3:45 / 6:58 where the 3:45 would update as the flv was scrubbed or played, or whenever a jump point was pressed. I found an example of this on this page.I have been using the as3 code to import my video and use cue points and for the life of me I cant get this to work.

I'm trying to modify an mp3 player to work on my site, and I can't seem to get it to display time elapsed and total duration. I've included the .fla file below so you can see it (keep in mind that the mp3 file it loads, and the title are both passed to it through the link, i.e. "mp3player.html?audlink=test.mp3&audtitle=This+Is+The+Title").

we have following class
[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. :)

is it possible to make the duration of a movieclip equal the duration of the preloader, i mean is it possible to make something like, the time the preloader needs to reach the 100% = the duration of the movieclip? i'm using AS 3.0 and flash CS4 just in case it helps here is my code for the loader:
Code:
loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
function loadProgress(event:ProgressEvent):void {
var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;

I noticed many players display audio track duration before loading the sound file, but I cannot figure out how that is done. So how can I get the duration of an mp3 file in Flex without having to load the file in a Sound object ? Think about loading 1000+ files in an application that has to immediately display the duration for each track.

I was wondering how do you inject metadata into an f4v file with quepoints? I've been reading somewhere that it's either during encoding or a custom actionscript that embeds when the file runs.

Is it possible using command line, or a php file to get the duration of an flv file using the flash media server. I used the flvcheck file to fix the meta data, and was using the duration operator but it didn't come up with anything. I am guessing the duration operator just shows if there is errors with this?

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.

For a research project I am looking for a way to collect the file system metadata of a certain file. The user selects a file on his system and the app retrieves the metadata of the file, only the metadata and not the actual contents. A friend of mine made a test app using SWFupload [URL] and it works, however not all attributes from the metadata can be retrieved. I would also want to collect 'lastaccesstime' and 'owner' from the metadata. Try the test app [URL]
The following code has been used to make this test app:
function fileDialogComplete() { //this.startUpload(); var f = this.getFile(); var a = "File Info
"; a += "Created: " + f.creationdate + "

1. Is there a method of determining the length of a sound file (mp3 primarily); in bytes, elapsed time, before the file is played? (the file could be played against a stop watch and the elapsed time record after the fact, programmatically).
2. Is it possible to set markers and fast forward/rewind to markers corresponding to the file?What I am thinking of is a feature allowing the user to play a file to a point and pause, set a marker, rewind and play to the marker and stop, or fast forward from the beginning and play from the marker, or even play past the marker and rewind to the marker.
Setting a marker would be the easy part: just record the elapsed time when the pause function is called.Getting the sound file to start playing from that point without the previous part played at normal speed;(with volume off) is the essential part of this question.

I'm really new about OOP AS3 programming, seems I can't fully understand how the eventcentral class works.For what I've understood this "system" allows classes to communicate between each other, passing parameters and call functions.So, having this ultra simple class:
Code: Select allpackage
{
import flash.events.*;[code].........
I'd like to execute (in the main class) the function "callthis" in the seconda class.

Is it possible, via Adobe Air, to save multiple types of data in a single file? For example, an application would allow the user to load in external images, position them on stage and label them. This data would be then be stored in a ByteArray (I guess) using BitmapData for the images and probably XML for the metadata.
I would then like to write this to a single file, with a bespoke file extension that could be associated with said Air app.

So I'm writing a Component for our artists to use and I need to be able to point at an XML document. I could have them simply write out the path in a string, but I'd like to allow them to navigate to the source file with a file browser if possible. I've looked through much of the documentation for metadata tags and haven't found anything "reliable"... for instance... [URL]. Lists possible "types" for [Inspectable] metadata, but it doesn't list nearly all of them... I'm currently using a type="Video Content Path" to let them browse to a video file... but I would think that Adobe would also have a type that allowed to browse to any file type, not just a video.

I want to use the Event metadata tags to show what types of event my control will dispatch. The syntax looks like:
<fx:Metadata>
[Event(name="eventName", type="MyEvent")]
</fx:Metadata>
It seems like a best practice in Flex/Actionscript to define static variables that define event names like so:
public class MyEvent extends Event
{
public static const EVENT_NAME:String = "eventName";
// Other stuff..
}
It's a great practice since the event name can change easily and not have to be modified throughout the code. So my question is: Is there any way to use this static const in my metadata event tag? I can't seem to do something like this:
<fx:Metadata>
[Event(name="{MyEvent.EVENT_NAME}", type="MyEvent")]
</fx:Metadata>
Am I just ignorant of the proper syntax to do this, or is it impossible? Seems like it's just asking for hard to find bugs if someone decides to change the const since it is not strongly typed here.

overriding 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've developed a neat WindowSWF panel after watching Lee's demonstration video. I got everything I needed to work, but I'm having trouble getting information from my sound files. Basically I have a list of sound objects (.wav format) in my library and I want to find the duration of each file so that I can add them to existing movie clips, then add or remove frames depending on the length of the sound file on the frame. I've been pouring over the jsfl actions libraries and can't find any method to get the duration of a selected sound file.

I need to be able to load a couple of external.swf files and have them play sequentially. To do that, I need to know the number of frames in the first .swf file so that I can check _currentframe against _totalframes to determine when it is finished playing so that I can load the second one.Most of the tips I see indicate that _totalframes on an external .swf can be determined by loading the.swf into a container clip and then checking using a listener within .onLoadInit. Like this:
---------------------------------------------------------------------- ------------------------------------------------
this.createEmptyMovieClip("tester_mc", 1);var mcListener:Object = new Object();
mcListener.onLoadInit = function(target_mc:MovieClip)[code].......
Unfortunately, that doesn't seem to work. The trace always returns a total frames of 1.I imagine this is because the container movie clip only has 1 frame, and the external .swf timeline appears to be ignored.how to gather the total frames of an external .swf file or, alternatively, tell in some other way when it is finished playing. (Not just loading, but playing to the end.)
