From 84556ef05963138cbc39fa1a39b790dffe15ffe8 Mon Sep 17 00:00:00 2001 From: Gyan Doshi Date: Sun, 5 Nov 2017 21:29:22 +0530 Subject: lavu/timecode: clarify error msg for timecode_rate The user-supplied value for timecode_rate in drawtext is rounded to nearest integer. So, a supplied value of 0.49 or lower is rounded to 0. This throws a misleading error message which says "Timecode frame rate must be specified". Changed message to account for values under one. Also noted supported framerates for drop TC.
