MP4 reader: only parse "moov" atoms once MP4 DASH files can contain more than one copy of the "moov" atom. Parsing it multiple times would mean that tracks, chunk offset tables, sample to chunk tables etc. would be filled multiple times as well. Commit 2b5e8c86a68943d93a60fe21a2920b14a9b9c053 made this easier to trigger, though the problem could have been hit with earlier code, too. Before that commit header parsing stopped as soon as the first "moov" and "mdat" atoms were found. Multiple "moov" atoms before the first "mdat" atom would therefore have triggered the bug, but I'm not aware of that having ever happened. Fixes #1877. 2017-01-29 09:31:07 +00:00			`#!/usr/bin/ruby -w`
