I was inspired by article about HD webcam on Bifferboard running Debian:
http://www.sunspot.co.uk/Projects/Bifferboard/biffer_build_root_files.html
and following Graham's  notes could set-up a HD webcam on Bifferboard with Logitech C510.
http://braze.net63.net/


Wanted to do the same on NanosG20 with the same webcam. 


But could not get more resolution than 640x480.
Is the USB chip on nanos too slow or I have not compile some driver for HD?



Below are mjpg-streamer installation notes:
====================================================================
Installing mjpg-streamer in /root folder

apt-get update
apt-get install make gcc dov4l libpt-1.11.2-plugins-v4l2
apt-get install subversion build-essential libjpeg62-dev libjpeg62

cd ~
wget http://sourceforge.net/projects/mjpg-streamer/files/mjpg-streamer/Sourcecode/mjpg-streamer-r63.tar.gz

tar xzvf mjpg-streamer-r63.tar.gz

cd mjpg-streamer-r63
make clean all
runs 10 min, produces warnings, but exits without errors.
===================================================================


Quick example: produces information about stream and runs in foreground:

##########################################
export LD_LIBRARY_PATH=/root/mjpg-streamer-r63
cd /root/mjpg-streamer-r63
./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w www" 
##########################################

The webpage page of streamer

http://192.168.0.5:8080/javascript_simple.html



Might want to put it in background using -b.
to kill this process might need to use use command 
kill -9 processnr 

Tried larger resolution -r 960x720 but that did not work.
