From 1b8e3801b2444f6e466e1b7c09cfc51605e80fb3 Mon Sep 17 00:00:00 2001 From: Frederik M J Vestre Date: Thu, 26 Jul 2012 14:38:32 +0200 Subject: Initial opus codec support Synchronised with opus repo on github (https://github.com/freqmod/rockbox-opus) Status: * Seeking ported from speex, but fails on some cases (e.g. seek to granule 0) * ReplayGain parsing needs to be reworked, we do vorbis-style replaygain now. http://wiki.xiph.org/OggOpus#Comment_Header explicitly forbids these in favour of R128_TRACK_GAIN tag. * No optimisation yet, source files still nearly identical to opus upstream * Multi-stream opus files may not be parsed correctly Change-Id: Ia66f1027dc1d288083e3c57b2816700078376f9a Reviewed-on: http://gerrit.rockbox.org/300 Reviewed-by: Bertrik Sikken Tested-by: Bertrik Sikken --- lib/rbcodec/codecs/libopus/celt/modes.h | 83 +++++++++++++++++++++++++++++++++ 1 file changed, 83 insertions(+) create mode 100644 lib/rbcodec/codecs/libopus/celt/modes.h (limited to 'lib/rbcodec/codecs/libopus/celt/modes.h') diff --git a/lib/rbcodec/codecs/libopus/celt/modes.h b/lib/rbcodec/codecs/libopus/celt/modes.h new file mode 100644 index 0000000000..c8340f9875 --- /dev/null +++ b/lib/rbcodec/codecs/libopus/celt/modes.h @@ -0,0 +1,83 @@ +/* Copyright (c) 2007-2008 CSIRO + Copyright (c) 2007-2009 Xiph.Org Foundation + Copyright (c) 2008 Gregory Maxwell + Written by Jean-Marc Valin and Gregory Maxwell */ +/* + Redistribution and use in source and binary forms, with or without + modification, are permitted provided that the following conditions + are met: + + - Redistributions of source code must retain the above copyright + notice, this list of conditions and the following disclaimer. + + - Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimer in the + documentation and/or other materials provided with the distribution. + + THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + ``AS IS'' AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR + A PARTICULAR PURPOSE ARE DISCLAIMED.
