Bug exists only under win32, because under linux both pins uses
MPlayer's MemAllocator class (with usable default values for buffer
size), but under win32 inputpin uses DirectShow's implementation of
IMemAllocator interface (with buffer count=0 and buffer size=1). Codec
does not do MemAllocator initialization for input pin (and it
should'nt i think. Allocator's properties are choosed by OutputPin,
IIRC) and default value (0 buffers of 1 byte size) are used.

Also tested with "realaud" and "raatrcwin" binary codecs.
