This is so frustrating.  I'm trying to use a live Axis webcam stream and the
overlay filter to put a logo in the corner of my video.  I've got this
working on an older Centos server but want to upgrade to a newer version and
I can't find one that works.

Last time I got this working by downloading libavfilter and checking out
ffmpeg with the checkout.sh script.  Now when I do that, the latest ffmpeg
snapshot doesn't stream smoothly on a recent copy of debian or Centos 6.2.

The last thing I've done is download ffmpeg-0.10.6 and built it from source. 
With this version, the camera is really smooth but the overlay doesn't

Any thoughts? Let me rock it Chaka Khan??  

Sorry that was random...  I've been working on this so long that I'm
starting to loose it.
