Just move your image display control inside the while loop.
Also don't forget to create image buffers to feed your vision functions... Otherwise you may have some strange behavior.

Live! webcam - VERY dark image
We have a new Creative Live! webcam. The picture generated by this camera is VERY VERY dark. We've tried using the driver from the CD and from the Creative website; different versions of the Webcam Center software; manually adjusting brightness, contrast, gamma, image size and frames per second. The image is still very dark. What can be done to correct this problem? We never had this issue with our old Creative PD0040?webcam. Image sample is at: HERE
Message Edited by SimpleSimon on 01-30-2007 12:08 AMI have a similar situation:
Case - In very low light conditions, with auto exposure ON: if I set FPS at 30, I actually get about 20 and a dark image as if auto exposure wasn't working
Case 2 - In very low light conditions, with auto exposure ON: if I set FPS at 25 or less, I actually get about 5 but a very good image (auto exposure works dramatically well).
Case 3 - In very low light conditions, with auto exposure OFF: effecti've FPS matches whatever I set it at, but I get a very dark image
Case 4 - Now, in low to normal light conditions, regardless of auto exposure being ON or OFF, I can set FPS at 30, actually get 30 and a very good image (auto exposure works dramatically well).
I'm curious why auto exposure seems to play such an important role on frame rate and image quality, under very low light. Is exposure adjustment done at the camera or by software? I'm running a 3 ghz processor with lots of headroom. -
Record from webcam to f4v on FMS
I'm trying to build / modify an application to record from webcam and microphone, in a web browser and save it to an FMS 5.4.2 server to stream via web and iOS
recording as a flv file works fine and it plays back just fine in firefox / any browser
I can steam f4v files over http as filename.f4v.m3u8 and that works fine with the samples that come with FMS from my record folder (/opt/adobe/fms/applications/record/streams/)
My flash web application can record to the FMS server, the file it records has the .f4v file extension, has content (i see the file size), and has time in quicktime (4 or 5 seconds - just a test) but it doesn't play - the screen is black and never starts.
I know i'm right on the edge of figuring this out, I just don't know what I'm missing or whats wrong (i'm a php programmer, not action script)
any ideas ?
here is the code i'm working with:

addCameraSettings()Hi,
Thanks for the details
First, the quality of the feed we get to the flash player and FMS is highly limited by the capabilities of the webcam that the users have beyond which we cannot improve the quality.
Next, flash player can encode good quality and hence you should probably find more stuff related to how best you can ingest video from a webcam on to the flash player.
- Does recording from server side with asc script will increase the quality ?
No, FMS does not do any type of transcoding/re-encoding stuff. All it does is to 'transmit' and in your case, to flush bits to the disk. So, unless FMS recieves 'Quality', it cannot do much.
- what configurations files on the server can i adjust to increase the recording quality ?
From above, it flows that, there are no configurations on the server that can make your quality grow. The configurations are more to do with delivery. It can be tweaked to improve streaming, reduce latency, quick start and more.
- is there a way to cache locally the stream if the bandwith is not high enough, and when the user stops recording, upload it to the server (it doesn't have to be live or broadcast).
I don't think flash player can do this.
Thank you ! -
Can't connect to FMS - trying to stream live from FME
Hi All
I've just signed up with an FMS host, but I am having trouble
using Adboe FME to stream live from my webcam to the host server.
When I do the following:
- I put rtmp://myaccount.myhost.com/MyApp into the Flash
Media Encoder FMS URL, with Stream name stream
- Click Connect
I get this error:
Problem with Primary Server
Failure to connect to primary server. Please veryify that
your Server URL, application name is valid and your internett
connection is working and retry.
The Encoding Log window also shows:
Primary - Connection rejected
I've tried:
- port mapping tcp 1935
- disabling my firewall
- changing the stream name
- changing the url to
rtmp://myaccount.myhost.com/MyApp/_definst_ (I read somewhere that
you can specify the instance - not sure if this is necessary)
Is there anything else I can try? The host says that it
should work.
Any help GREATLY appreciated.
Cheers
TDear T
I'd say it should work too. Unfortunately Flash Media Encoder
doesn't give you detailed error - just a generic.
Can you ping the host from your machine
(myaccount.myhost.com) ?? What is the content of the log file?
FME doesn't require fixed IP or port mappings. Ensure that
MyApp is correct and created on the server!
What kind of hosting company is this? I think they should
help you - it doesn't look professional to me.

Unable to capture video from webcam in JMF in xlet
hi
I am unable to capture video from webcam in an Xlet. I am using Xletview to run Xlet. The method CaptureDeviceManager.getDeviceList(vidformat) returns empty array. Which videoformat should I use and why do I get empty array?
Thanks
RajeshMHP and OCAP only use JMF 1.0, which does not include support for capturing video. You will not be able to do this in any current MHP/OCAP imlementation that I know of.

Creative Live wireless webcam - DDNS or any other outside access doesn't work
Bought the Creative Live Wireless webcam. Works inside my network, but DDNS server offered by Creative has been down for weeks now, so I can't use this service. The remote IP access also does not work, since the webcam doesn'y assign a remote IP (it states 0.0.0.0).
No support infor on Creative web page at all, they don't even list the product. I feel like this is all a big scam....
Can anyone provide insight in how to the this product to work?Did you get an auto response to your e-mail? Once a request arrives a response goes out automatically. If you didn't get that, check your spam filter first as the reply may be stuck there.
If for some reason you did not receive any response at all, please send me a PM with your contact details. I will have someone look into your issue.

How to Display a image from WebCam in the Forms 10.1.2.0.2!
Hi Friends!
I'm using a Forms 10.1.2.0.2 and i need to display of someway a image from webcam in some item inside the Forms!
This is possible?
I saw an explanation in http://www.orafaq.com/forum/t/89431/67467/ but it works only for a Forms 6.0!
Somebody can Help me?As Jan mentioned, there is no way to display webcam video in Forms unless you create a Java Bean which can be incorporated into your form. As Pauli mentioned, if your webcam software is viewable via a browser, you can use WEB.SHOW_DOCUMENT to display a browser window with the content, however you will not be able to put this content in the form using the method.
A good starting place would be Google. Look for a java bean or applet which can operate a web cam.

How to have a web-based interface for Lumira that also performs Ad-Hoc visualizations on data that should be loaded live from HANA. I have another tool that puts data into HANA, So don't want to reload this new data into Lumira every time I want to run a report.
so do i have the ability to create polished ad hoc dashboards, reports, infographics and storyboards Apart from Ad-Hoc reports, I also need a dashboard with some fixed reports that update with the live data.
So please suggest me to accomplish this task.
Thanks and regards
Shashi kiranPlease have a look at Ludek's document here which contains links: SAP Lumira Family Supported Versions Matrix
Ludek has also attached the PAM's as zipped files; Lumira comes in many flavors so I encourage you to research options

I Want To Transmit Audio from Mic and Video from WebCam.....???????????????
I Want To Transmit Audio from Mic and Video from WebCam on Another Computer. I have used AVTransmit2.java file and AVReceive2.java file for Transmission and Receiving but They Transmit Only Video On Another Computer on a network without any error. Any One Help me How Can i Transmit both Audio & Video at the Same time ????????
i m using This Command for Transmittion
java AVTransmit2 vfw://0 192.168.0.1 192.168.0.2 10000
and this Command For Receiving
java AVReceive2 192.168.0.1/10000 192.168.0.2/ 10002Excuse me foro my bad English but I speak English like Tarzan.
To trasmit both video and audio I created a MergingDataSource wich incorporates video and audio data sources. Then I created a Processor with this DataSource and a RTPManager for each track of the processor. It works.

How flash player takes raw data from webcam to display it ?
Hello,
I would like to know that how flash player takes data from webcam and display it on video display object, does flash player process the raw data comes from webcam meanscompress it or apply any kind of matrix / filter and then display it on video display object or stage ?
Thanks,
Jankrutto create a movieclip button:
create a movieclip (insert/new symbol/movieclip) and attach a stop() to its first frame and label it "up". create whatever graphics you want for the button movieclip's up-state. create an "over" frame and, if needed, a "down" frame.
when you place this movieclip button on-stage give it an instance name (say, printer1) and use:
printer1.onRollOver=function(){
this.gotoAndStop("over");
printer1.onRollOut=printer1.onDragOut=function(){
this.gotoAndStop("up");
printer1.onPress=function(){
this.gotoAndStop("down");
// and add your onRelease to do whatever.
if you also wanted to add a textfield that displays the button's instance name when the button is rolled-over, place a textfield on the "over" frame and give it an instance name (say tf) and attached to the movieclip's "over" frame use:
tf.text=this._name; -
View video from webcam while transmitting
Hi everyone, when I try to use AVTransmit3.java and Clone.java (example from sun) to see video from webcam while transmitting, an error occur:
{color:#ff0000}+java.lang.NullPointerException+
at com.sun.media.codec.video.colorspace.RGBConverter.process(RGBConverter.java:352)

So I'm only able to see in local my captured video, but cannot transmit.
I try to debug JMStudio to find how to do this(monitoring transmitted video), but I'm not able to debug it.

thank you in advanceI post all the class I use in this project.
Copy and create your own project (SERVER side)
Then on other pc (CLIENT side) run JMStudio and open RTP transmission: you will receive data but on server you will have a black window.
I've modified only AVtransmit3.java -> look at Main() and modify dest-ip and port.
JFrameMain is a class with a button to close the application.
