I would play the source to single jpeg files (mplayer $src -vo jpeg), do the transformations on the jpegs (e.g. via graphicsmagick), and then use mencoder to combine the jpegs back to a video file. Or use a program that is made to edit video files, perhaps Kino, Cinelerra or Blender/VSE can do that. Greets, Kiste
