From eee13d653953083553cceadbbedf6222ef78a006 Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Sun, 15 Mar 2015 23:40:06 +0200 Subject: movenc: Only adjust the cts offset at the start of fragments if necessary MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adjusting it is only necessary when a sidx/tfrf/tfxd atom already has been written for the previous fragment (since the sidx/tfrf/tfxd atoms include the duration between the first pts of the previous fragment, to the first pts of the new fragment).
