looking at the messages, jevois-daemon is requesting YUYV 320x240 @ 50fps from the camera, and the camera does not accept that format. For the JeVois camera, indeed this format is not a valid output format given the default videomappings.cfg. Please see this thread for more explanations:
http://jevois.org/qa/index.php?qa=155
Now, for your built-in camera, maybe try to have a look at what it can support, you can do that either with
lsusb -vv
and look for the various resolutions and modes under your camera and under "Videostreaming interface descriptor", or
guvcview -w1
which will list all the pixel formats and video resolutions supported by your camera. Remember (as in thread 155 mentioned above) that you then want to select a videomapping in jevois-daemon that uses one of your camera's supported modes as its input (camera) mode.
