Nils Wallménius 082cd01eb2 opus: speed up deemphasis Remove downsampling code from deemphasis loop as we don't use it and remove multiplications that are not relevant when not using custom modes. Saves 1.4MHz on h300 (cf), 4.3MHz on c200 (pp) and 4.6 on fuzev1 (amsv1). Change-Id: Iab3f1d737a656a563aaa351d50db987a9cff2287		2012-09-28 00:09:54 +02:00

Libraries:  Opus (snapshot) / Opus-tools (snapshot) / libogg 1.3
Imported:   September 15th, 2012

Steps taken to adapt original opus/opus-tool/ogg source files to rockbox
(useful when for example syncing a new snapshot)

Opus:
* copied .c/.h files from opus/src lib/rbcodec/codecs/libopus
* copied .h files from opus/include to lib/rbcodec/codecs/libopus
* copied .c/.h files from opus/celt to lib/rbcodec/codecs/libopus/celt
* copied .c/.h files from opus/silk to lib/rbcodec/codecs/libopus/silk
* renamed opus config.h file to opus_config.h and replaced #include "config.h",
  for example
find . -name "*.h" -print | xargs sed -i 's/include "config.h"/include "opus_config.h"/g'
find . -name "*.c" -print | xargs sed -i 's/include "config.h"/include "opus_config.h"/g'

Opus-tools:
* copied src/opus_header.h and src/opus_header.c to lib/rbcodec/codecs/libopus
* changed #include <ogg/ogg.h> to #include "ogg/ogg.h" in opus_header.c

Ogg:
* copied libogg/src/framing.c to lib/rbcodec/codecs/libopus/ogg
* copied libogg/include/ogg.h to lib/rbcodec/codecs/libopus/ogg
* changed #include "ogg/ogg.h" to #include "ogg.h" in framing.c
* added os_config.h to lib/rbcodec/codecs/libopus/ogg
