MP4 does not really support "growing" live files, so that shouldn't be a
problem. And if fragmented MP4 is used, the sample tables will be reset on each
fragment.


I think for push mode there is nothing we can do here, however for pull mode it
could make sense to only parse and store a part of the sample table and when
more is needed go back to the moov and parse the newly needed part while
dropping the old one.
