well if you call av_estimate_timings at 80% of a file it would with
your change estimate the bitrate and duration based on the last 20% or?
now seek back to the start, maybe the seek code ignores duration and
start time but thats not guranteed and actually the seek code should
use the duration and start time instead of redoing the estimation ...
