Message:

From Rafa Gaitan, "Current ffmpeg plugin didn't support pause and seek, I have added this
functionality and I also modified osgmovie example to support "seek"."

Note from Robert Osfield, changes osgmovie to use '>' for the seek as '+' was already used in a separate submission that had been merged.
