wrong dimensions from camera #24

Closed nylki closed 7 years ago

nylki commented 7 years ago

continuing the other issue: sudo modprobe bcm2835-v4l2 on raspberry pi 3 with latest rasbian and picam2 worked. Tested it with the motion tool to capture frames via v4l2.

However when starting reactivision 1.5.1 I get a wrong camera resolution (848x32 with a framerate of 30FPS). Setting any manual width/height in the camera.xml results in this dimension. When doing capture width="max" height="max" it actually works sometimes, sometimes it crashes. It reports 3280x2462. The maximum width/height might be much for the raspberrypi to handle.

I also tried reducing the framerate to 15fps but the option seems to be ignored and is set back to 90fps.

Is there something I might be missing?

you can list all available formats with reacTIVision -l it's a long list since the raspicam driver only provides stepwise image formats, no standard resolutions ... you should be able to choose any of those combinations shown

thank you, choosing a resolution from the list and entering the values into the XML worked just fine!
