Notes for getting Logitech QuickCam Pro for Notebooks camera streaming over wifi

Gstreamer and uvc_stream

Download source

I grabbed svn on --Paulcox 13:41, 27 August 2010 (CEST)

svn co https://mjpg-streamer.svn.sourceforge.net/svnroot/mjpg-streamer mjpg-streamer

Build

Small changes required in Makefiles due to cross compilation for ARM architecture of overo (don't worry, painless)

Modify Makefiles

In mjpg-streamer/Makefile and uvc-streamer/Makefile I put:

DESTDIR = /home/paul

# set the compiler to use
#CC = gcc
OVERO_OE=/home/paul/overo-oe

CC = $(OVERO_OE)/tmp/cross/armv7a/bin/arm-angstrom-linux-gnueabi-gcc
CROSS_COMPILE=$(OVERO_OE)/tmp/cross/armv7a/bin/arm-angstrom-linux-gnueabi-

ARCH=arm

GLIB_INC = $(OVERO_OE)/tmp/work/armv7a-angstrom-linux-gnueabi/glib-2.0-2.22.4-r1/staging-pkg/staging/armv7a-angstrom-linux-gnueabi/usr/include/glib-2.0
GLIB_LIB = $(OVERO_OE)/tmp/work/armv7a-angstrom-linux-gnueabi/glib-2.0-2.22.4-r1/staging-pkg/staging/armv7a-angstrom-linux-gnueabi/usr/lib/

I also had to do this in all the Makefiles in the plugins folder

Remove header

apparently libv4l2.h which is included in a few files is no longer included. Thankfully it doesn't appear to be needed so commenting the references works ok :

paul@paul-laptop:/media/PackBell_Linux/overo-oe/mjpg-streamer/mjpg-streamer$ find . | xargs grep -n "libv4l2.h"
./plugins/output_http/httpd.c:40://#include <libv4l2.h>
./plugins/output_http/.svn/text-base/httpd.c.svn-base:40:#include <libv4l2.h>
./plugins/input_uvc/v4l2uvc.h:35://#include <libv4l2.h>
./plugins/input_uvc/.svn/text-base/v4l2uvc.h.svn-base:35:#include <libv4l2.h>

patch available here

Build uvc_streamer

paul@paul-laptop:/media/PackBell_Linux/overo-oe/mjpg-streamer/uvc-streamer$ make

Build mjpg-streamer

paul@paul-laptop:/media/PackBell_Linux/overo-oe/mjpg-streamer/mjpg-streamer$ make

copy to target

scp uvc_stream  @auto3:
scp *.so start.sh mjpg_streamer @auto3:mjpg-streamer
scp -r www @auto3:mjpg-streamer

start streaming

Log in

ssh auto3

Look around :

root@overo:/home/paul# ls

capture.elf ffserver.conf mjpg-streamer overo_twist.elf uvc_stream

Go for it:

root@overo:/home/paul# ./uvc_stream

Coming soon

ffmpeg, mplayer, mencoder, vlc, gstreamer. what was library needed libav? installing with opkg "opkg install <name>", proxy setup in /etc/opkg/opkg.conf setting up x-forwarding over ssh tunnel?
