Hi I had a question and was wondering if anyone could help me. This is about a 2 year old question that I have not had any luck with and I was hoping that now that the RPi2 has come out maybe I can accomplish this project.
I'm looking to take the RPi camera stream and put it in a window via python preferably with pygame. I wanted the resolution to be twice that size of the window. Lastly when the arrow keys are pressed I want the streaming video to move around by 1 pixel in the corresponding direction. I want to do all of this on the Pi and put it out directly on my HDMI screen without using servers or networks.
Again I tried this about 2 years ago with the UV4L driver, which didn't work for this. Plus I cant get it to work on the RPi2 currently. I then also looked into seeing if this could be done with the picamera "pure python camera interface" and to my knowledge it cant.
Does anyone have any pointers to help me with this. It's a really simple goal, and I don't know why the picamera struggles with it so much. If I use a USB camera, this is super easy and works because I can access the /dev/video0, but has terrible fps when I tried on the Model B. Maybe the Pi2 could handle it better.
Any help would be appreciated
