From 6122d83981b85997e1fc1e3962c7aca3c3ab6714 Mon Sep 17 00:00:00 2001 From: Uoti Urpala Date: Tue, 1 Feb 2011 21:15:16 +0200 Subject: tremor: drop internal tremor library Drop internal copy of the tremor library. Note that the internal ogg demuxer (which is still sometimes useful to work around libavformat ogg demuxer problems, though it's itself quite buggy) now cannot be compiled without either external libvorbis or libvorbisidec (tremor). --- tremor/window.c | 84 --------------------------------------------------------- 1 file changed, 84 deletions(-) delete mode 100644 tremor/window.c (limited to 'tremor/window.c') diff --git a/tremor/window.c b/tremor/window.c deleted file mode 100644 index cc92f979ac..0000000000 --- a/tremor/window.c +++ /dev/null @@ -1,84 +0,0 @@ -/******************************************************************** - * * - * THIS FILE IS PART OF THE OggVorbis 'TREMOR' CODEC SOURCE CODE. * - * * - * USE, DISTRIBUTION AND REPRODUCTION OF THIS LIBRARY SOURCE IS * - * GOVERNED BY A BSD-STYLE SOURCE LICENSE INCLUDED WITH THIS SOURCE * - * IN 'COPYING'.
