Hi Tim

See inline.

That's why i wrote "Unless Broadcom did something really stupid ...".
Github was down last night so I couldn't check the source of raspivid - and
a little bit busy with a customer today.

That said, raspiyuv can deliver stills as YUV or RGB. And after all, video
is a long row of successive stills so maybe there is a way.
