a bit complicated, but you can do that by doing screenshots with gstreamer, send it to a videoloopback device and read that (with pdp, Gem, GridFlow or whatelse) - get v4l2loopback (http://code.google.com/p/v4l2loopback/) compile, install, load the module - get gst-v4l2loopback (http://github.com/umlaeute/gst-v4l2loopback) compile (need gst-plugin-base-dev), install run the gstreamer-pipeline, e.g. $ gst-launch ximagesrc use-damage=false startx=0 starty=0 endx=640 endy=480 ! queue ! ffmpegcolorspace ! v4l2loopback access the video using [pix_video], [pdp_v4l2] [#camera] or cat running here. this of course only grabs a portion of the screen, rather than a window and track that... fgmadfs IOhannes
