Hi! VLC got this vlc v4l2://
captures ok but skype and programs like you mean doesn't it seems that kernel do support V4L all modes - both 1 and 2... r...@kuzmin-desktop:/home/kuzmin# grep -i v4l /usr/src/linux-headers-2.6.32-22-generic/.config CONFIG_VIDEO_V4L2_COMMON=m CONFIG_VIDEO_ALLOW_V4L1=y CONFIG_VIDEO_V4L1_COMPAT=y CONFIG_VIDEO_V4L2=m CONFIG_VIDEO_V4L1=m CONFIG_V4L_USB_DRIVERS=y Another way to do is to preload some modules: LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype But it doesn't work to - skype does not show, mplayer does not capture - as if the /dev/video0 return's datafile of null length Have some idea's workaround?
