Hi,

Did you ever find a solution to this problem?

When I specify a custom KSALLOCATOR_FRAMING_EX in my audio driver, via the DECLARE_SIMPLE_FRAMING_EX() macro, it makes absolutely no difference to the size of the frames passed to my pin's process function (stream->Offset->Count is always 4096 bytes)

Any advice on how to get KS to pass me the correct size of frame?

Hi,
The AVStream documentation states:
“AVStream provides a default allocator. The default allocator allocates pool memory based on the allocator requirements that the minidriver provides in the AllocatorFraming member of the KSPIN_DESCRIPTOR_EX structure.”

I provide the AllocationFraming in my capture mini-diver, but still get frames of a size that is different from what I specified.
What could be wrong?
TIA
Andrew
