Hello Anders
I found a small time for testing your code. But your code doesn't work
with my webcam. :-(
I think it doesn't have the same sensor. Can you add in the sd_init

your sensor id :

It is _not_ present in the stream.

But I have the same problem as you about the image data. I don't know

About the JPEG images, the Huffman table is always the same
Does this mean that it's the same for all JPEG images or only for one
camera?
