There is actually no need for an extra function. When you have the video frame buffer you can get the bytes from it:

    local videoframe = mpeg.get_frame(self.video)
    if videoframe then
        local bytes = buffer.get_bytes(videoframe, "rgb")
        -- use bytes with gui.new_texture() and gui. gui.set_texture_data()
    end
