KongQun Yang 9a55d4033f Adjust timestamps in mp4 if there is an initial composition offset
In some ISO-BMFF files, there is an initial non-zero composition offset,
but there is no EditList present.

This is against ISO-BMFF spec recommentation [1] and we believe in most
cases it is just missing the EditList.

[1] 14496-12:2015 8.6.6.1
It is recommended that such an edit be used to establish a presentation
time of 0 for the first presented sample, when composition offsets are
used.

Issue: #112.
Fixes: b/110782437.
