From e23a01c06df324d66b3924c3ea47cd5cf5ec017e Mon Sep 17 00:00:00 2001 From: Ludmila Glinskih Date: Fri, 31 Jul 2015 16:01:43 +0300 Subject: api-seek-test: first version Works only with video stream. First pass without seeking -- counts crcs of a frames and store it in an array. After that it seeks a lot in different places and checks if crcs of these frames and crcs of frames in array are the same.
