Are such keyframes set when encoding uncompressed
video?  I use mplayer for my research.  I encode
.avi files from sequences of .png source material.
I would very much like to get mplayer to single
step on frames but, so far, have failed to be able
to do it.  Even when I set fps to 1, rapidly
hitting the space bar twice moves me ahead 3 or
more frames.

Is there any way to get single step action via the
encoding process?
