ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Mon Jul 25 13:52:59 2016 +0200| [a115eb9e750543f1d8bf951414d291069bf396c2] | committer: Anton Khirnov

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.
