From 8dc72eeaf647736c287b59a3856a11904bedd58b Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Thu, 19 Mar 2015 09:28:25 +0200 Subject: udp: Fix crashes after adding AVOptions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a missing AVClass member, check whether localaddr is null. (Previously, localaddr was always a local stack buffer, while it now also can be an avoption string which can be null.) This fixes crashes when not passing any localaddr parameter, since 66028b7ba.
