target_verbose - Increase frameserver callback verbosity
nil
target_verbose( tgtvid, state )
Exposing hi-frequency events from a frameserver to the scripting environment
comes at a certain cost which although it may be negligible most of the time,
it is still unnecessary. This function can increase the level of verbosity
associated with a frameserver. An example for the use of this function is to
get raw timing and framestatus updates from video playback (decode
frameservers with a framequeue associated).
This behavior can be switched on or off dynamically by setting
state to 1/true(default) or 0/false.
