From 18f2d5cb9c48d06895960f37467576725c9dc2d1 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Sun, 20 Nov 2011 17:19:25 +0100 Subject: [PATCH] mpegvideo: Don't use ff_mspel_motion() for vc1 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Using ff_mspel_motion assumes that s (a MpegEncContext poiinter) really is a Wmv2Context. This fixes crashes in error resilience on vc1/wmv3 videos.
