Published on June 3, 2013

As our USB cameras are UVC compatible, we can just plug in to any Windows XP, Windows 7 running PC and start using the camera with the simple GraphEdit tool.

In this blog I am going to walk through the steps required to record a video from the USB camera using a GraphEdit.

  • Once we stop the graph by “Graph MenuàStop”, we will be able to playback the recorded file ”testvideo.avi” using VLC player.

Resolution Change:

    • If we want to record at desired resolution (say for ex: 5MP MJPEG), we can switch the resolution before starting the graph. By right clicking on the “capture pin” of the e-con 5MP Camera, select the resolution as 2592×1944 and format as MJPEG. Click Ok and close the dialog.
