Recording from webcam in Flex

Hi!
I was wondering if I am able to record the images of a webcam in Flex. Is it possible, and if so, how can I make it?
I'm using MJPEG images (ByteArray stream), so can it be a possible way to paste/add images to a Movie (or sg like that) object, and then save it?
Jus a thought, but any solution interests.
Thanks a lot
Milo

Do they allow me to track the mouse easily across the whole
screen or is it just for pieces?
I probably should have explained better earlier but I am
looking to somehow record all their movements across the
application to get a better idea of how the user is interacting and
thinking about the experience. I am not really sure what I am
looking for here but it is my guess that these listeners just check
for moving x amount of pixels one way or another. Do these allow a
more robust method of capture?
Sorry I cannot go any more detailed than that since I am not
really sure what I am looking for yet - I'm just trying to see what
is out there and what others might be doing.
Thanks for your suggestions,
-Dan

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:

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 !

Recording from webcam into fcp

Can you record video from a web cam directly into FCP?

Final Cut doesn't capture from USB sources. If you're referring to a built-in iSight, then it's a USB camera. Quicktime Player can record video from it, though.

OnLocation fails to record from Microsoft LifeCam Studio 1080p HD Webcam

Hi,
I finally installed and configured OnLocation on my laptop, and I was looking forward to shooting 1080p footage in my car. Imagine my disappointment when it turned out that OnLocation refuses to record from the camera! I know the camera works because other software can use it (alas, at 720p). Why is it I am not having any luck with this? All the other forums suggested that OnLocation is the ultimate tool for mobile recording to disk, and now I can't even get it to show me the live footage. What gives?

Video stream recording (not webcam) help required

I am making a media player / recorder type web application in flex 4.
The application plays video streams streamed from my red5 server.
I want to give users the ability to make / record clips of the video they are viewing.
I know that netstream.publish is used to record/save video on the server.
All the help i've found on google so far just give examples to save video from webcam.
But i want to save video from a video being streamed from red5 server and being played
on VideoPlayer control in flex.
All help is greatly appreciated.
Thanks.

hello,
first get the length of the datagrid.
suppose your datagrid id is db and you want to delete the the row which have same name .....
first get the selected row and from that name of the selcted row.
supoose selected name is
var index:int=db.selectedindex;
var selname:string =bd.dataprovide.getItemAt(index).name;(name id datafield of the column).
now you got the selected name search for the same rows in datagrid.
var totallen:int=(db.dataprovider).length;
for(var i:int=0;i<totallen;i++)
    var checkduplicate:string=bd.dataprovide.getItemAt(i).name;
   if(checkduplicate==selname)
     db.dataProvider.removeItemAt(i);
this will delete all the row which are with same name with selected row name...

How to record from the video in or S-video Ports on Qosmio G40?

Can anyone tell me how to record from the video in or S-video ports, because i've tried the Ulead DVD factory program and the only capture device it could see was the webcam, and it did capture from it
After that i've downloaded the update file that was provided by the support website
The devices that the program could see are the TV tuner and the webcam (which it couldn't access anymore for some reason)
After that i've downloaded a newer update which simply is the same as the last update and seems that someone in the support website directed the link of the new update which they don't have to the file of the previous update which doesn't really do anything.

Hi
There are 2 s-video ports; s-video out port is not designed to capture the signals from any external source. The name of this port says everything; its an OUT port!
The s-video-in port must be placed at the right side of the notebook. Dont mix the both ports. But note; this port receives only the video signals. To hear the sounds, use a video cable to connect the sound terminals of the audio device and your computer.
Red: sound right channel
White: sound left channel
The Ulead DVD Movie factory can be used to capture this signal.

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

MHP 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.
