There's a very simple program to capture a jpeg from the bktr interface called bktr2jpeg that should do the job - a search should find the code quickly enough (it's a single C file very simple code, the meteor man page has enough information to rewrite it). You could also set ffmpeg to run at 4 frames per second and emit an MJPEG, AVI or MPEG stream.
