nwal002 [mjpg streams and slugos]

vor mehr als 2 monaten hatte ich den wunsch, live-bilder von meinem wohnzimmer aus ins internet zu streamen. hardware hatte ich schnell gefunden, die logitech quickcam pro 9000 sollte meine bedürfnisse abdecken, zumal hd-qualität [1600x1200] unterstützt wird.
leider gibt es unter dem derzeitigen kernel [2.6.21.7] von slugos 4.8 keine oder nur mangelhafte v4l [video for linux] unterstützung und die suche nach dem passenden treiber wurde zu einem hürdenlauf. but I am running successfully for today mjpg StreamServe service under slugos. puts you on the distro worth less, can be found at this blog already a firmware binary image based on the nslu2 openwrt. here is a manual for those who have slugos as target platform.
the resources we are currently running compile against the v4l kernel. within this package, there is also the appropriate driver [ http://linux-uvc.berlios.de/ ] for the Logitech QuickCam Pro 9000
in turn - we put the camera on the usb hub on the slug. lsusb recognizes the device immediately and report:

# lsusb-s 2:4-v
Bus 2 Device 4: ID 046d: 0990 Logitech, Inc.
thus we come to the driver installation. download the archives

# wget http://linuxtv.org/hg/ pinchartl ~ / uvcvideo / archive / tip.tar.gz
# gzip-d # tar xvf tip.tar.gt
tip.tar

dannach the unpacked archive change

# cd uvcvideo-33fd4f6f3afa
# make
# make install

compile to be successful is an actual linux-src-environment condition that also requires a, cross-compile-environment '[ required to install packages using ipkg - autoconf, automake, cpp, g + +, g + +-symlinks, gcc, glibc-utils gnu-config, kernel-dev, ldd, libgcc, libglib, make, makedevs, ncurses, ncurses-dev, update-modules]. also to compile kernel module - git and svn [Optware repository].

install linux resources:

# cd / usr / src # wget
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.7.tar.gz
# gzip -d linux-2.6.21.7.tar.gz
# tar-xvf linux-2.6.21.7.tar
# ln-s / usr / src / linux-2.6.21.7 linux
# ipkg install kernel-dev
# cp / boot / config-2.6.21.7 / usr / src / linux / .config

so that any references of the driver package [uvc] on native kernel-objects can be linked to compile wir alle kernel-module [nativ auf der slug dauert das etwas ~2h]

# cd /usr/src/linux
# make menuconfig
# make modules

jetzt haben wir unter /lib/modules/2.6.21.7/kernel/drivers/media/video die aktuellen kernel-module der video4linux umgebung, und diese werden von nun an in das memory geladen.

# cd /lib/modules/2.6.21.7/kernel/drivers/media/video
# insmod v4l2-compat-ioctl32.ko
# insmod v4l1-compat.ko
# insmod videodev.ko

the installation of any compatible software packages [http://www.quickcamteam.net/software/linux/v4l2-software] runs unspectacular. quite quickly find yourself with uvccapture-0.5, uvc-streamer and just deal mjpg-streamer.
