## PURPOSE

WORKED=NEXT(VR)

## SYNOPSIS

## DESCRIPTION

    WORKED=NEXT(VR)
      Advances to the next frame in the video.  Returns 0 if the next frame is
      not available.

      After the videoReader constructor is called, NEXT, SEEK, or STEP should
      be called at least once before GETFRAME is called.

      See videoReader/getinfo for more details on how many frames can be read
      from a video.
