From 1b168a428d0f401261484f39eeb007cb5430130c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Reimar=20D=C3=B6ffinger?= Date: Fri, 8 Jan 2010 19:31:33 +0000 Subject: [PATCH] Ignore 0-height slice in sws_scale, otherwise a final 0-height slice will cause libswscale to assume the incorrect slice order and complain about slices starting in the middle.
