Debian-Linux UVCインストール

UVCインストール

apt-get install subversion
apt-get install linux-headers-`uname -r'

svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
cd trunk
make
make install

USBカメラを接続してドライバーが起動するかどうかを確認。

dmesgで見える。
または/var/log/messagesや/var/log/syslogを覗けばメッセージが見れる。

インストールしたときはドライバーが起動しなかったように見えたが、別の日に同様に行った時はUSBカメラを接続するとドライバーが起動するのが見えた。

fswebcamで動作確認

UVCはV4L2対応らしい。V4L2に対応したアプリでなければ動作しないようだ。

apt-get install libgd2-dev
mkdir workdir
cd workdir
wget http://www.firestorm.cx/fswebcam/files/fswebcam-20070108.tar.gz
tar zxvf fswebcam-20070108.tar.gz
cd fswebcam-20070108
./configure
make
make install

$ fswebcam -d /dev/video0 -p YUYV -r 352x288 output.jpeg

暗いし、同期がずれている。いまのところ対処不明。
