r_frame_rate is NOT the average frame rate, it is the smallest frame rate
@code{r_frame_rate} is NOT the average frame rate, it is the smallest frame rate
that can accurately represent all timestamps. So no, it is not

If you are looking for the average frame rate, see @code{AVStream.avg_frame_rate}.
