VideoDisplay control

According to the Developers guide in flexbuilder 2 you can
use the videodisplay control to stream video. The code they show is
this:
<?xml version="1.0"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
// Define a variable of type Camera.
import flash.media.Camera;
public var cam
public function initCamera():void {
// Initialize the variable.
cam = Camera.getCamera();
myVid.attachCamera(cam)
]]>
</mx:Script>
<mx:VideoDisplay id="myVid"
width="320" height="240"
creationComplete="initCamera();"/>
</mx:Application>
So they are creating a camera object using the
creationComplete event in the videoDisplay control.
My question is how does the control know where the camera is.
If I have the camera connected to my laptop (via USB) and my laptop
is on the network, how do I point the control to the camera?

It uses the default camera installed on your system.
Check getCamera() method on this link

VideoDisplay control in Vista

We are using the VideoDisplay control to display a .flv file
being streamed from a stream server. It works great except I can't
get it to work on Vista clients. I've tried it on 2 seperate Vista
machines. Does anyone know if this control is not compatible with
Vista yet?
Thanks in advance,
Todd

What is your code for streaming the video? Also, are you
using the VideoDisplay in a component or directly in your code? If
you can post some of the relevant code for your app, that might
make it easier to find the problem. Since the VideoDisplay control
itself works with Vista, the problem must lie elsewhere.

Why spark videodisplay control does not work when i run the application?

Even in the mode design I can not see the video, thks.....

@Jorge,
Try using file:/// instead of file:/.
This seems to work for me:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:VideoDisplay x="159" y="96"
            source="file:///C:/Documents and Settings/pdehaan/My Documents/My Videos/walking.flv"
            loop="true"
            width="384" height="267"/>
</s:Application>
But I'd probably recommend copying the .FLV file into your Builder project or putting it online instead of trying to play it back from a hardcoded file:/// path.

Setting playheadTime in VideoDisplay

I encountered a weird behaviour of the playheadTime setter in
the VideoDisplay component.
It seems like I'm getting the right value from it, but when
I'm trying to set it - the playhead jumps to an unexpected point in
the video.
In the code below I'm setting the playheadTime to "1" when
the "skip" button is pressed, but it is actually jumping to the
6.974s point in the video.
Can you tell me what I'm doing wrong?
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Panel x="22" y="66" layout="absolute" width="572"
height="474">

autoPlay="false" horizontalCenter="0"/>

</mx:HBox>
<mx:Button label="Skip" click="mainVid.playheadTime=1"
x="271" y="304"/>
<mx:TextInput x="360" y="292" width="51" height="24"
text="{mainVid.playheadTime}" />
</mx:Panel>
</mx:Application>

This has to do with the FLV format and not the VideoDisplay
control. The NetStream.seek() function which VideoDisplay
encapsulates can only seek to key frames.
A Key Frame in a video is a frame that is redrawn completely.
When you are compressing your FLV's you have many options to set
for Key Frames. The more Key Frames you have the bigger the file
size, most FLV's are probably compressed at 15-30 fps and will have
their Key Frame rate set to every 50-100. At 30 fps and every 100
frames make a key frame you are actually only getting new key frame
every ~3 seconds.
No when the NetStream.seek() function is called it finds the
closest Key Frame after the time value you give it. So basically
the video you are watching has a Key Frame at 0 seconds and
6.974s.

Mx:videodisplay.totalTime = -1

I am trying to build a custom-progress bar which includes
both the download progress as well as the play progress of an
mx:videodisplay control, and allows the user to seek based on where
on the progress bar they click.
Here's how I am doing it:
capture the position of the click from mouseEvent
use it to calculate a percentage for how far down the
progress bar the click occurred (0.0-1.0)
multiply percentage by video.totalTime to determine what the
desired time is
set playheadTime equal to desired time
My problem is that the totalTime property is returning -1.
The video, however, remains playing, and the playheadTime property
is legit too - the clock still counts up every second of the video
as it plays. But since the totalTime property is -1 everything else
gets screwed up, and when I attempt to seek anywhere, i get Error
1003: Invalid Seek - understandable since seeking to a negative
time doesn't make sense.
Any information anyone has about how the totalTime property
is calculated would be appreciated. Also below are a couple pieces
of the code:

Update. When I add single line "System.gc()" in onTimer function I no longer have a crash and memory usage is constant.
Best Regards, Aleksey

VideoDisplay no longer works

I set up a project which was very simple.
I dragged a videoDisplay control onto the screen and set the
parameters:
Live="true"
Autoplay="true"
source="rtmp://ipaddress/app/instance/video
runnning the application worked fine and the live streaming
video was running fine.
I create 3 videoDisplay controls in total where each one was
puuling a different stream, when I ran it it worked fine showing
all three streams.
That was yesterday.
Today when I went to edit some basic cosmetic issues where I
never touched the VideoDisplay I started getting:
Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095:
flash.net.NetConnection was unable to invoke callback onBWDone.
error=ArgumentError: Error #2126: NetConnection object must be
connected.
I now cannot stream live video.
Any ideas please?

Hi lynettec,
When you say Acrobat doesn't work in Firefox, do you mean that you can't view PDF files in the Firefox browser? If so, please see View PDF files in Firefox without downloading them | Firefox Help
If you're referring to the Acrobat online services, they are supported in Firefox, so I'd would need a little more information about what's happening to get to the bottom of the problem.
Best,
Sara

Error When connecting to FLVs via Vitalstream's Media Server

Hello,
I get an error everytime I try to connect to an FLV using
Vitalstream's Media Server. I have turned on and off the

Need help setting up Flex on server (sdk?)

This should be a simple noob question:
I have Flex Builder on my local machine. I've created an
application (project.mxml) that uses VideoDisplay to play some
videos chosen from a List using an XML file as the data source. The
app works great testing on my local machine.
I now wish to take my project and put it on my Windows 2k3
server.
I copied over my project directory to the server at
D:\Flex\ProjectName, and I set a website in IIS using home
directory D:\Flex.
At this point, I go to my local machine and punch in the URL,
http://10.xxx.xxx.xxx:8700/ProjectName/bin/project.html,
which brings up my application UI. I can see the app, it looks
identical to my local machine. However, when I go to select my
video from the List, nothing plays. I've included a function that
checks for connection and it doesn't report back with an alert.
As for the server, it has the newest version of Flash player
(not sure if this is even needed on server side?) and it also has
the Flex Data Services 2 installed (yes, I'm using Flex 2). I don't
even think I need the FDS2 installed at the moment since I'm not
really connecting to any data sources other than this xml file, but
I installed it as a precaution since i have it installed on my
local machine. This is as far as the server is setup for Flex. I've
looked at documentation and its not clear to me as to what needs to
be on the server to get Flex apps to work. Do I need to install
Flex Builder on the server? Or the SDK? And what files am I
supposed to give the server from my local machine? I've spent a
great deal of time on this to see it fail on the server, so any
help is appreciated.

I've added FLV to the MIME extensions list and restarted
WWWPS
Still no video connection. Sigh, this is weird. I am able to
directory browse and I can see the videos.
Something strange happens though. If I directory browse to
/vids/, I can see all my FLV's. However when I click on one, it
gives me a "Server Error" - Either the Macromedia application
server is unreachable or it does not have a mapping to process this
request.
I changed my script a bit to point to another XML file
located on the web,
http://ws.jamesward.org/youtube.xml
and modified my dataProvider and the source spots to fit his
structure and it displayed his youtube videos.
I'm going to try using full URL addressings for each video
url on my XML file, though I think I did this already without
progression.
Let me know about that error I reported.
EDIT: Using the full URL didn't work. It's still giving me a
connection failed alert.
EDIT2: I made a new mxml file with just a
<mx:VideoDisplay> control only. I set the source to the full
URL path of a single video on my server and tested the app locally.
It would not display the video. I then set the source to the
relative path of the same video on my local machine and the video
played. So it's definitely something with my server handling these
FLV's.
EDIT3: Just to note, my server also has ColdFusion 7.0.2
running on it. I don't know if that explains the error
above?

Video Clear

Hi everyone, I'm trying to create a videochat using Flex 3
and Flash Media server and I have some problems with the method
"Clear" of Video object. When a user stop publishing its stream
(from the webcam), I receive an event because a shared object
property (with the id of the publisher) changes to "null". At this
time, I invoke the method "clear" of the video object that contains
the stream, but the screen (videoDisplay containing the video
object) doesn't change. I continue seeing the last frame received.
What can I do? Thanks!!

You could also subclass the VideoDisplay control and add your
own public "clear()" method which calls the
mx_internal::videoPlayer.clear() code.
[ActionScript]
package {
import mx.controls.VideoDisplay;
import mx.core.mx_internal;
public class MyVideoDisplay extends VideoDisplay {
public function MyVideoDisplay() {
//TODO: implement function
super();
public function clear():void {
pause();
mx_internal::videoPlayer.clear();
[/ActionScript]
[MXML]
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:custom="*" layout="vertical">
<custom:MyVideoDisplay id="myVideoDisplay" source="

/>
<mx:Button label="clear" click="myVideoDisplay.clear();"
/>
</mx:Application>

Yes, the VideoDisplay component doesn't have a UI, so you'd
have to build
one of your own using the components available in Flex.

HPUX on IA64: Error when connecting to SAP via librfc

I presume it has something to do with 32/64 Bit, because we also had problems with our own programs. On HPUX socklen_t is 64 bit (parameter of getsocket), and perhaps librfc thinks, it only has 32 bit and give an int as parameter.
Is there anything I can do?

Help with RSS

Hi guys
Basically, I would like to create a panel for Photoshop CS4
getting an RSS feed of my video tuts. I know how to put the video
window but I would like the RSS links to show the video once
clicked. Kind of like what Scott Kelby did
HERE
but instead of showing the blog post, it would be the video that
would play.
On the back end, would I have to create a separate feed and
blog page with direct video links?
Thanks!

If you know action script and MXML, you can modify the RSS
sample in the Flex Builder.
Use the VideoDisplay control show the video.
