From c0ee4e0ac2c46bb4904ceec12b7dfa480517e7bf Mon Sep 17 00:00:00 2001 From: Karthick Jeyapal Date: Fri, 28 Sep 2018 12:55:54 +0530 Subject: avdevice/decklink_dec: add option to align capture start time This option is useful for maintaining input synchronization across N different hardware devices deployed for 'N-way' redundancy. The system time of different hardware devices should be synchronized with protocols such as NTP or PTP, before using this option.
