initProc video filter method

initProc

Initializes a filter's per-instance data.

int initProc(VDXFilterActivation *fa, const VDXFilterFunctions *ff);

Parameters

fa	Pointer to filter activation structure.
ff	Pointer to callback function structure.

Thread safety

This method is not thread-safe.

Exceptions

Exceptions may be thrown from this function (see Except()).

Return value

Zero on success, non-zero on failure.

Default behavior

If omitted, no default action is taken.

Remarks

This function is called whenever a filter instance is created, and is usually used to initialize variables in the private data structure. Regardless of whether it is provided, VirtualDub will initialize the data structure to zeroes, so most filters will not need this function.
