Subject: vc1: fix a memleak.
X-Git-Tag: v10_alpha1~203
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=de4ec972c06d9047bc1b73bb13f858a5d77d8df0;p=platform%2Fupstream%2Flibav.git

vc1: fix a memleak.

Happens on a B-frame when neither low_delay nor last_picture_ptr is set
(probably corrupted streams only).
