From 552a99957f7c6f6ed13795caee7ab7b9deb5d76e Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Thu, 12 May 2011 22:47:53 +0300 Subject: rtpdec_qdm2: Don't try to parse data packet if no configuration is received MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The later parsing of payload data depends on the configuration being present. If it hasn't been configured properly yet, parsing a data packet may lead to a crash.
