From 985f34b75653d02eda8eb8def3412f8577f19b01 Mon Sep 17 00:00:00 2001 From: Janne Grunau Date: Sat, 15 Jun 2013 22:11:55 +0300 Subject: [PATCH] utils: fix avcodec_flush_buffers pre-reference counting compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The to_free AVframe must be freed just like the other ones. Indeed, the calling application may expect all frames to be released. (This regression caused use-after-free in VLC with hwaccel.)
