description => "Should frame analysis try and be efficient in skipping frames",
help => qqq("
In previous versions of ZoneMinder the analysis daemon would
attempt to keep up with the capture daemon by processing the
last captured frame on each pass. This would sometimes have the
undesirable side-effect of missing a chunk of the initial
activity that caused the alarm because the pre-alarm frames
would all have to be written to disk and the database before
processing the next frame, leading to some delay between the
first and second event frames. Setting this option enables a
newer adaptive algorithm where the analysis daemon attempts to
process as many captured frames as possible, only skipping
frames when in danger of the capture daemon overwriting yet to
be processed frames. This skip is variable depending on the
size of the ring buffer and the amount of space left in it.
Enabling this option will give you much better coverage of the
beginning of alarms whilst biasing out any skipped frames
towards the middle or end of the event. However you should be
aware that this will have the effect of making the analysis
daemon run somewhat behind the capture daemon during events and
for particularly fast rates of capture it is possible for the
adaptive algorithm to be overwhelmed and not have time to react
to a rapid build up of pending frames and thus for a buffer
overrun condition to occur.

ZoneMinder::ConfigData - ZoneMinder Configuration Data module
=head1 SYNOPSIS
use ZoneMinder::ConfigData;
use ZoneMinder::ConfigData qw(:all);
loadConfigFromDB();
saveConfigToDB();
=head1 DESCRIPTION
The ZoneMinder:ConfigData module contains the master definition of the
ZoneMinder configuration options as well as helper methods. This module is
intended for specialist confguration management and would not normally be
used by end users.
The configuration held in this module, which was previously in zmconfig.pl,
includes the name, default value, description, help text, type and category
for each option, as well as a number of additional fields in a small number
of cases.
=head1 METHODS
=over 4
=item loadConfigFromDB ();
Loads existing configuration from the database (if any) and merges it with
the definitions held in this module. This results in the merging of any new
configuration and the removal of any deprecated configuration while
preserving the existing values of every else.
=item saveConfigToDB ();
