From 8fd3e02eee87e0830fa7ab1dbb65160e5be76d20 Mon Sep 17 00:00:00 2001 From: Bela Bodecs Date: Sun, 1 Jan 2017 11:00:45 +0800 Subject: [PATCH] libavformat/hlsenc: default segment name and use_localtime in hlcenc.c, in the hls_write_header() function the default format string for strftime() function contains %s specifier when use_localtime is true. This %s specifier will insert the seconds since EPOCH. But %s is not available on all system/environment. This patch check %s availabilty at runtine and alter the default format string if necessary.
