From 7447045cc0dacf9eedf230070c0675eecf546ff6 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sat, 20 Jun 2020 07:06:04 +0200 Subject: [PATCH] avformat/webvttdec: Accept \r as newline After parsing the end timestamp of a WebVTT cue block, the current code skips everything after the start of the timestamp that is not a \t, ' ' or \n and treats what is next as the start of a WebVTT cue settings list. Yet if there is no such list, but a single \r, this will skip a part of the cue payload (namely everything until the first occurence of \t, ' ' or \n) and treat what has not been skipped as the beginning of the WebVTT cue settings list that extends until the next \r or \n (or the end).
