[debian-users:54571] ffmpegが動きません



お世話になります。
ffmpegを、Synapticからインストールしましたが

~$ ffmpeg -f video4linux2 -s 320x240 -i /dev/video0 /tmp/test.ffm

とのエラーで動きません

確認のため、xawtvをインストールしてみると
~$ xawtv

と、どうやらvideo4linux2がインストールされていない?
そこで
~$ svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk linux-uvc
svn: No repository found in 'svn://svn.berlios.de/linux-uvc/linux-uvc/trunk'
とのことで、リポジットがありません
どこに行ったんでしょうか?
