PFNKSFILTERVOID callback function

Description

An AVStream minidriver's AVStrMiniFilterReset routine is called when AVStream receives an IOCTL_KS_RESET_STATE to return the filter to the state it was in at Acquire-time. This routine is also called when a queue associated with a pin on the filter is flushed. This routine will only be called for a filter-centric filter.

Parameters

Filter [in]

Pointer to the KSFILTER to return to its previous state.

Return value

AVStream does not currently use the return value.

Remarks

For more information, see Filter-Centric Processing.

Note that it is not the filter in question, but rather a pin on this filter that actually receives the reset IOCTL.

The minidriver specifies this routine's address in the Reset member of its KSFILTER_DISPATCH structure.

The filter control mutex may be held during this function. See Filter Control Mutex in AVStream.

This routine is optional.
