virtual-player

Create a named virtual player in Media Flow Controller with policies for delivery; the virtual
player can then be used in a namespace, see
player types correspond to those types of videos; for example, if you intend to deliver
YouTube® videos, create a type youtube virtual player for the corresponding namespace.
When you create a virtual player of any type with virtual-player <name> type <type>, you
enter virtual-player prefix mode. This makes configuration easier if you have a set of
command values to enter with copy-and-paste. To leave the virtual-player prefix mode, use
exit. Use no to negate or disable settings.
These are the general virtual-player commands; not all options are available for all types.

Note! There is an implicit virtual player that is set with the network connection commands. If
no virtual player is assigned to a namespace, that namespace uses the network connection
values. If a defined virtual player is assigned to a namespace, the virtual player values
override the network connection values. See
