Seem amsn now use libng from the xawtv package you need to add a converter for 
the MJPEG palette and uncomment the YUYV converter (untested)  set in the 
libng package (I am looking at the CVS code). You can get the MJPEG converter 
from uvcview in the utils.c file.

uvcview in YUYV grab the stream and forward to the display 
in MJPEG add the missing Huffman table, decompress the jpeg picture to YUYV 
and forward to the display.
