and i want unknown no.of files to be read at runtime.

is it possible to customize the push source filter like that.

Yes.


You need to supply the images to the downstream filter in FillBuffer so you
could read the images there as needed.

but in GetMediaType function there is a statement like this

// Copy the header info from the current bitmap
memcpy(&(pvi->bmiHeader), m_pBmi , m_cbBitmapInfo );

how to get the bitmapinfo before executing the fillbuffer function..


thank u ...

You can do your initialization for your samples in your constructor for
your source filter or its output pin's constructor.

An alternative is to do this in a custom interface.
