estimate duration as soon as we have 3 frames.

Right now the duration estimation happens after every 1.5 seconds
So in case of files which are less than 1.5 seconds,
the estimation never happens. But to estimate the duration
3 frames are enough. So instead of waiting till 1.5 seconds,
estimate the duration as soon as we get 3 frames and then continue
estimating every 1.5 seconds from that time

The update interval is calculated as 
parse->priv->update_interval = fps_num * 3 / (fps_den * 2)
for default framerate, it comes out to be 57 frames for 1.5 seconds.

Previously the estimation was
57, 114, 171, ......
after the patch it will be
3, 60, 117, 174, ......

Even this case, it needs a minimum of 2 buffers while encoding. As with 1
buffer there is not enough data to estimate.
