From a115eb9e750543f1d8bf951414d291069bf396c2 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Mon, 25 Jul 2016 13:52:59 +0200 Subject: [PATCH] mimic: do not release the newly obsolete reference at the end of decoding The reference frames are used in update_thread_context(), so modifying them after finish_setup() is a race. The frame in question will be released during the next decode call.
