public static class avfilter.AVFilter.Init_AVFilterContext
extends FunctionPointer
Filter initialization function.
This callback will be called only once during the filter lifetime, after
all the options have been set, but before links between filters are
established and format negotiation is done.
Basic filter initialization should be done here. Filters with dynamic
inputs and/or outputs should create those inputs/outputs here based on
provided options. No more changes to this filter's inputs/outputs can be
done after this callback.
This callback must not assume that the filter links exist or frame
parameters are known.
