Move error code definitions from libavcodec/avcodec.h to
libavutil/error.h. Error code definitions and handling code belong to libavutil, where they can be shared by all the libav* libraries. See the thread: Subject: [FFmpeg-devel] [PATCH] Move error codes definitions from lavc to lavu Date: Sun, 19 Jul 2009 12:09:16 +0200 Originally committed as revision 22501 to svn://svn.ffmpeg.org/ffmpeg/trunk
