SetVideoCache
|
||
|
|
=============
|
||
|
|
|
||
|
|
.. function:: SetVideoCache(vnode clip[, int mode, int fixedsize, int maxsize, int historysize])
|
||
|
|
:module: std
|
||
|
|
|
||
|
|
Every filter node has a cache associated with it that
|
||
|
|
may or may not be enabled depending on the dependencies
|
||
|
|
and request patterns. This function allows all automatic
|
||
|
|
behavior to be overridden.
|
||
|
|
|
||
|
|
The *mode* option has 3 possible options where 0 always
|
||
|
|
disables caching, 1 always enables the cache and -1
|
||
|
|
uses the automatically calculated settings. Note that
|
||
|
|
setting *mode* to -1 will reset the other values to
|
||
|
|
their defaults as well.
|
||
|
|
|
||
|
|
The other options are fairly self-explanatory where
|
||
|
|
setting *fixedsize* prevents the cache from over time
|
||
|
|
altering its *maxsize* based on request history. The
|
||
|
|
final *historysize* argument controls how many previous
|
||
|
|
and no longer cached requests should be considered when
|
||
|
|
adjusting *maxsize*, generally this value should not
|
||
|
|
be touched at all.
|
||
|
|
|
||
|
|
Note that setting *mode* will reset all other options
|
||
|
|
to their defaults.
