Many thanks Carl that fixed it.

I guess the inference that I had missed is that there's some kind of
default encoding going on here--it's not just a network pipe. Is that a
general case for ffmpeg, or is it specific to streaming, or perhaps this
streaming mode? (and, far less important since I doubt I'll ever want to
use it, is the encoding predictable, or does it vary by build?)
