Calculate a new player rating for this item.
The decision which player to use for a VideoItem is based on this
rating. First each player plugins is asked for a rate, on how good it
can play this VideoItem. There are three possible rates: good (=2),
possible (=1) and unplayable(=0). This rate is then weighted by a
factor of ten. Next the user's choice of prefered players is checked.
The user can define a rank list of players with the variable
VIDEO_PREFERED_PLAYER in local_conf.py. The rank that is calculated
from this config variable is then added to the current rate. Last but
not least there is the possibility that for some reason the use of a
special player is forced. In that case a value of 100 is added to the
rate.
In the end a sorted list of possible_players is created. All players in
this list have a rating for this special VideoItem of not less than 10.
The first one is the default one, the others are offered to the user as
choices in the "Alternate Player" menu.
