@spectacularcrackers Late reply. I just grab pictures regularly, not record videos. take a look this [WebcamAndMicrophoneCapture](https://github.com/bytedeco/javacv/blob/master/samples/WebcamAndMicrophoneCapture.java)

Thank you for your reply. How can I modify my configuration to use it.Any suggestions.

This is the method I am using, it seems that there is no good way to deploy with local resource. Thank you.
