From 202947a0665ea523022afb0a6c50eed96bcd6b69 Mon Sep 17 00:00:00 2001 From: "Pedro E. M. Brito" Date: Sun, 28 Dec 2014 05:35:34 -0200 Subject: libavformat/segment.c: Add strftime expansion for segment filename templates Allows expansion of the filename template with strftime() with the option -strftime 1 (disabled by default). This allows segments to be named by time of creation, adding some flexibility. Fixes Ticket 4104 (add strftime to segment muxer) Signed-off-by: Pedro E. M.
