思って自作2号機に取り付けてみました。
/usr/ports/multimedia/webcamdをインストールします。webcamdと一緒にcuse4bsdがインストールされます。
インストール後は以下の設定をします。
*********************************************************************
1) webcamd requires the cuse4bsd kernel module, please load this
by doing
# kldload cuse4bsd
or adding
cuse4bsd_load="YES"
to your /boot/loader.conf.
2) Please restart devd as the configuration changed
# /etc/rc.d/devd restart
*********************************************************************
で、この後は、
Dreamcraft2# kldload cuse4bsd
Dreamcraft2# webcamd &
Attached ugen7.2[0] to cuse unit 0
Creating /dev/video0
それから、ビューワーをインストールしましょう。
Dreamcraft2# cd /usr/ports/multimedia/pwcview
ビューワーのインストールが終わったら、pwcviewを起動します。
こんな感じで動いていればOKです。
pwcviewのヘルプは以下のとおりです。
