ffmpeg | branch: master | Xi Wang <xi.wang at gmail.com> | Wed Nov 14 02:52:32 2012 -0500| [e8769b37fe8a841c0d28d3686c6d3cdecc542bc7] | committer: Martin Storsjö

segment: fix NULL pointer dereference in seg_write_header()

Since the pointer `oc' is NULL, oc->oformat->name will cause a null
pointer dereference.  This patch changes it to seg->oformat->name.
