Note: Using nanoseconds as GStreamer does is lossy, but it poses no rounding problems by itself as long as the demuxer is careful and only converts to nanoseconds at the end. Then, working with nanoseconds is safe as long as only additions and subtractions are performed. That is not the case with floats, where even common operations like addition are dangerous.
