# record frames from a public camera in jyväskylä city centre for timelapse purposes etc
# uses threads, probably to not miss any frames, non threaded version commented in bottom

# written in 2016 during random student event happening in the city centre
# demo video https://youtu.be/tMSrBDwmtUo compiled with ffmpeg. 
# stutters a bit cause duplicate frames are not processed
