I try to record a video with my USB Webcam in a QT GUI Application on my Raspberry Pi. All tutoriuals I can find focus on cross-compiling. I want to program and build this directly on the Pi. I've succesfully installed QT Creator and build GUI Applications, they're working.

Questions:

  • Is it possible to implement OpenCV into the RaspberryPi QT Creator? If yes, how?
  • Is this the correct approach to solve the problem?
  • Is there a better way to record videos with a QT GUI Application beside Open CV?

Thank you very much!

  • opencv will take ~2gb disk space while building. also, if all you need is recording video, opencv might be way too heavy. (plugging into ffmeg, gstreamer might be more adequate) – berak Jul 16 '14 at 08:34
  • Yeah - I thought about that, too. Is it possible to use ffmpeg in QT? Do you have any example or tutorial about implementing? I think I've already installed ffmpeg to test the webcam (streamed it to the browser) – Jonas Zimmer Jul 16 '14 at 08:45
  • sorry, no idea (not into Qt at all). – berak Jul 16 '14 at 08:47
