From 4a72765a1c94b05bd3053b1f34f8457a3b71d714 Mon Sep 17 00:00:00 2001 From: Reimar Döffinger Date: Wed, 9 Feb 2011 19:32:07 +0100 Subject: Do not fail DVB sub decoding because of a few padding bytes Instead of returning an error when bytes are left over, just return the number of actually used bytes as other decoders do. Instead add a special case so an error will be returned when none of the data looks valid to avoid making debugging a pain.
