+#### Note about Linux systems
+In Linux it may be a bit harder to set the enviorenmente properly. More specifically it may be hard to install required codecs.
+If having a codec problem (like "couldn't find codec for id 27") you may need to compile ffmpeg and opencv by yourself.
+You should be good using these guides (tested on Ubuntu with success and on Debian without success)
