[theora] video files contain one frame more than encoded

ogg/theora files produced with libtheora-1.0, according to mplayer,
contain one frame more than encoded, and the last two frames in the
file are at the same time (correct time of the last encoded frame).

Is that normal or maybe a bug or a mistake in encoding?

If it should be normal: What is the reason? Can it be prevented? How
is the relation of the nominal time of the frames in the file to the
time at which the encoded frames were aquired --- is there some
interpolation in time? I need to know the real time corresponding to
each frame in the file ...
