Overview
We are often asked if mediaCam can record video from an application, for example capturing an instant messenger webcam session, or an online demonstration video. MediaCam can capture these applications but it some cases your display adapter will require its settings to be changed to allow this to happen.
Setting up your Display Adapter
Unfortunately some graphic cards do not display video onscreen but in an overlay if you find when recording you get a blank or sometimes pink/purple box where the video should have been your graphic card is using an overlay.To allow you to record the video you will need to turn down your hardware acceleration on your graphic card. This can be done by a right mouse click on the desktop to pull up the 'Display Properties' dialog box.
Now select the 'Settings' tab and choose the 'Advanced' button.
Select the 'Troubleshooting' tab and alter the hardware acceleration control until your video can be captured.
You may want to return the original settings once you have captured you video as disabling acceleration can reduce performance on certain applications.
