Frozen video on calls


Try putting the camera under VFW (Video For Windows) control - it involves a registry edit and can be found here
http://help.yahoo.com/l/us/yahoo/messenger/messenger10/webcam/mstacamfix.html
It didnt work for me at first - I had to download the windows amcap as well. VFW doubled my fps
If you open the 'webcam' menu on the webcam picture frame and also open 'Statistics' you can monitor the f/p/s during transmission - Generally try and keep the frames per second above 1.0 fps to prevent freezing. I transmit the 'small image' with my contacts and they zoom up to 200% -all on the webcam frame menu. When you open 'Statistics' you can tell if you are on VFW control - it will say VFW along the lower panel.
I also increased my virtual memory following an error message.

Video conferencing starts fine but after a minute or so my video freezes. When I turn it off and on again it starts back up but only for about 20 seconds until it freezes again.


If you are trying to use Yahoo conference facility put your webcam under Video For Windows control ( VFW )

http://help.yahoo.com/l/us/yahoo/messenger/messenger9/webcam/mstacamtest.html

You have use IE to automatically download this program by just visiting the page - it will make a small registry change and for me, increased the frame/per/second f/p/s by 100%
To check your webcam is working in VFW when broadcasting in messenger, open 'Webcam' menu on the frame and select 'Statistics' VFW should be displayed on the bottom.
Also save resources by transmitting the small picture option and your contacts can zoom up to 200% using the 'Webcam' menu on the top of the picture frame.

Hi,
VfW (Video for Windows)mis old (and not being developed any more) and because of its limitations,Microsoft has come up with a new device driver model: WDM (supported nativelystarting from Windows 2000). Most video capture drivers are now being developed using WDM.

I think if you get the latest DirectX drivers it'll work better.

Hope this helps

Normal 0 Did you install the software with the camera connected to the computer? Disconnect the camera from the USB port and reinstall the software. When the program asks you to connect the camera, do so, and it should work. Hope this is of some help. Bud

Below is info for setting up Audio & Video to chat on line after you install , either Skype or a messenger program.


Web Camera’s have to be setup on the program they are to be used with. Just installing the camera on your computer does not set it up to broadcast on messengers or Skype.
Each program has Options that have to be setup in order for the Audio and Video to function properly.
A. Skype Setup:
After downloading and installing Skype set it up as follows:
  1. Go to TOOLS, then OPTIONS, and click on Audio Settings and set the Microphone and Speakers to the computer Audio Card.
  2. Then click on the Video Settings.
  3. The camera if installed properly will come up and show a picture.
  4. Then on the bottom of the page click on Save.
The camera and audio should function properly. Your friends and Family will now see and talk to you.
B. Yahoo Setup:
After downloading and installing Yahoo Messenger set it up as follows:
  1. Go to Messenger at the top left and click on it.
  2. Next go down to Preferences and click on it.
  3. Next Calling and Devices on the right and set the Microphone and Speakers to the computer Audio Card.
  4. Next go to the Test Audio section and (in blue writing) click on “Open the call setup assistant” and follow the instructions on the left window.
When done both the Audio and Video will function properly so you can chat and see family or friends you are connected to.
Hope this helps. Bud
