Run “gstreamer-properties“, click the “Video” tab, change Default Input Plugin to “Custom”, and add this Pipeline:
v4l2src ! ffmpegcolorspace ! vertigotv ! ffmpegcolorspace
Now when Empathy video-chatting with a friend, you can give them a headache!
Or give yourself a headache by trying it directly from the command line:
gst-launch v4l2src ! ffmpegcolorspace ! vertigotv ! ffmpegcolorspace ! xvimagesink
Feel free to replace “vertigotv” with any other or more of the video effects listed in “gst-inspect effectv“.
Here’s me with edgetv ! vertigotv:

I’m surprised that some of the effects available haven’t found their way into cheese yet. It’s a shame that you need to hit the command line to get the empathy effects running, they’d be a nice thing to have as an option in empathy, esp if integrated with a GtkCheese widget

*That* is cool. Why can’t this be found anywhere in Empathy or another GUI?

Can you explain how the ‘!’ is being used here? It looks like its designating some kind of pipe but after some searching I can’t find out how it works. All I see from the bash references is that the exclamation can be used to run commands from the history.

It’s used by gst-launch to set up its internal stream pipeline; it’s not a shell operator, it’s just a “normal” command argument.
