# SetVideoCache

std.SetVideoCache(vnode clip[, int mode, int fixedsize, int maxsize, int historysize])

  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.
