Manipulating /dev/video
For sure. Here are two suggestions:
- Behind the scenes CLI. Use V4L2VD to create a virtual video device such as /dev/videoVirt1 and pipe through mplayer for the effects. Even some similar examples in the notes.
- Use a fat desktop program such as webcamstudio to create the pipes and do your skype/broadcast wonders - still with mplayer for the ascii effect
Good Luck!
Here's another v4l2 loopback driver that I was able to get working with Skype. v4l2loopback driver Then you can use Gstreamer to setup to pipeline.
apt-get install gstreamer-tools
gst-launch -v v4l2src ! gstreamfiltershere ! v4l2sink device=/dev/video1
