From 19de452a630f0906ef3ebda4f27ca7b2a4b59f07 Mon Sep 17 00:00:00 2001
From: Justin Ruggles <justin.ruggles@gmail.com>
Date: Mon, 22 Mar 2010 21:58:38 +0000
Subject: Move ff_flac_write_header() to flacenc.h, which removes the Matroska
 muxer's dependency on flacenc.o and fixes the unnecessary dependency on
 vorbiscomment.o.
