From b85130bb29281ee7d6dca2b12a3408720cb2871d Mon Sep 17 00:00:00 2001 From: Valera Rozuvan Date: Wed, 26 Feb 2014 15:13:22 +0200 Subject: [PATCH] Show start time or starting position on slider and VCR. When the start time is set, or a initial position is set,the VCR timer and the time slider should jump to correct starting point before the video starts playing.
