[gst-devel] bufferpools, filter templates

No, of course not ! The more data it can handle, the better.

The reason I did passthrough the way it is now (inefficient by copying the
data again) is for a new plugin writer to be able to see what he needs to
change and quickly implement a new filter, which in the general case could
have a different output sample rate than input.  In many cases, indeed, a
filter might do an in-place edit, so I follow you on the distinction
there.

I'm hoping to replace filterstamp by something a bit more general,
building a plugin from a template (on which wtay can tack a wizard ;) ),
but as all of you that depends on the free time I have to waste.
