From 9326d64ed1baadd7af60df6bbcc59cf1fefede48 Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Tue, 25 Nov 2014 10:39:50 +0200 Subject: Share the utf8 to wchar conversion routine between lavf and lavu MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This doesn't add any dependency on library internals, since this only is a static inline function that gets built into each of the calling functions - this is only to reduce the code duplication.
