or...
mplayer -vo null -ao null -frames 0 -identify "$original_name"
2>/dev/null |   | sed -e '/ID_VIDEO_WIDTH/s/ID_VIDEO_WIDTH=//'
mplayer -vo null -ao null -frames 0 -identify "$original_name"
2>/dev/null | sed -e '/ID_VIDEO_HEIGHT/s/ID_VIDEO_HEIGHT=//'

you could probably do it with a single sed line, but I'm not that
versed in sed....
