DIdnt work on Linux Mint 19.3, seems "QtGStreamer" is missing and after installing it complains about another kde lib....
It was almost a blank interface with the fun game of what does this button do?
Photo part works good. Program halts by take a video. Linux Mint 17.1 KDE and an old webcam.
Seems like it shouldn't have been released yet. Oversites like a "record" button but no "stop" button. Try Guvcview or Cheese instead.
