From 203e3f28fbebec7011342017fafc2a0bda0ce530 Mon Sep 17 00:00:00 2001 From: Jean-Michel Trivi Date: Fri, 8 Apr 2016 12:05:12 -0700 Subject: AAC/SBR decoder improvements and bugfixes * AAC-Decoder - Add support for AOT 20 (ER-AAC scalable) (base layer only) - Add support for AAC as used in Digital Radio Mondiale (DRM30/DRM+) Modified file(s): libAACdec/src/aacdecoder.cpp libAACdec/src/aacdecoder_lib.cpp libFDK/src/FDK_core.cpp libFDK/src/FDK_tools_rom.cpp libMpegTPDec/src/tpdec_asc.cpp libMpegTPDec/src/tpdec_lib.cpp libMpegTPDec/src/version libSBRdec/include/sbrdecoder.h libSBRdec/src/env_extr.h libSBRdec/src/sbrdecoder.cpp Added file(s): libMpegTPDec/src/tpdec_drm.cpp libMpegTPDec/src/tpdec_drm.h - Fix sanity check in HCR module that was performed at the wrong point in time. Modified file(s): libAACdec/src/aacdecoder_lib.cpp libAACdec/src/block.cpp - Extend core sampling rate support up to 96 kHz. Modified file(s): libAACdec/src/aac_rom.cpp libAACdec/src/aacdecoder.cpp libAACdec/src/aacdecoder_lib.cpp - Return correct audio output channel description according number of output channels. Modified file(s): libAACdec/src/aacdecoder_lib.cpp - Indroduce decoder intern output buffer. This change allows to use framework output buffer with the actual size of the deocder output channels. Modified file(s): libAACdec/include/aacdecoder_lib.h libAACdec/src/aacdecoder.h libAACdec/src/aacdecoder_lib.cpp * SBR-Decoder - Increase robustness for erroneous input data. - Improve error concealment performance. - Fix handling of lowest sub-band for LD-SBR Modified file(s): libAACdec/src/aacdecoder.cpp libAACdec/src/aacdecoder_lib.cpp libSBRdec/src/env_calc.cpp libSBRdec/src/env_dec.cpp libSBRdec/src/env_extr.cpp libSBRdec/src/env_extr.h libSBRdec/src/sbr_dec.cpp libSBRdec/src/sbr_rom.cpp libSBRdec/src/sbr_rom.h libSBRdec/src/sbrdecoder.cpp - Add QMF delay compensation for ELD v2 streams decoded with the complex low delay filter-bank. Modified file(s): libSBRdec/src/sbr_dec.cpp libSBRdec/src/sbr_dec.h libSBRdec/src/sbrdecoder.cpp - Introduce a different handling of frames to be flushed dependent on whether there are delayed frames available or not. Modified file(s): libSBRdec/src/sbr_ram.h libSBRdec/src/sbrdecoder.cpp - Calculate the correct number of samples for dual-mono copy in case of no available PS data. Modified file(s): libSBRdec/src/sbrdecoder.cpp * SYS-Library - Change include order of genericStds.h to prevent conflict with definitions which are also used in math.h. Modified file(s): libSYS/src/genericStds.cpp Change-Id: I3ecffbad85f39b056213107955cfadbeb3f4b6e1 --- libFDK/src/FDK_core.cpp | 2 +- libFDK/src/FDK_tools_rom.cpp | 198 ++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 197 insertions(+), 3 deletions(-) (limited to 'libFDK') diff --git a/libFDK/src/FDK_core.cpp b/libFDK/src/FDK_core.cpp index f4b510d..1d8ac7b 100644 --- a/libFDK/src/FDK_core.cpp +++ b/libFDK/src/FDK_core.cpp @@ -93,7 +93,7 @@ amm-info@iis.fraunhofer.de /* FDK tools library info */ #define FDK_TOOLS_LIB_VL0 2 #define FDK_TOOLS_LIB_VL1 3 -#define FDK_TOOLS_LIB_VL2 5 +#define FDK_TOOLS_LIB_VL2 6 #define FDK_TOOLS_LIB_TITLE "FDK Tools" #ifdef __ANDROID__ #define FDK_TOOLS_LIB_BUILD_DATE "" diff --git a/libFDK/src/FDK_tools_rom.cpp b/libFDK/src/FDK_tools_rom.cpp index 49f0ee1..29e37f2 100644 --- a/libFDK/src/FDK_tools_rom.cpp +++ b/libFDK/src/FDK_tools_rom.cpp @@ -2236,7 +2236,7 @@ static const rbd_id_t el_aac_cpe1_epc1[] = { ics_info, ms, ltp_data_present, - ltp_data, + /* ltp_data, */ global_gain, section_data, scale_factor_data, @@ -2247,7 +2247,7 @@ static const rbd_id_t el_aac_cpe1_epc1[] = { next_channel, ltp_data_present, - ltp_data, + /* ltp_data, */ global_gain, section_data, scale_factor_data, @@ -2290,7 +2290,178 @@ static const element_list_t node_aac_cpe_epc1 = { { &node_aac_cpe0_epc1, &node_aac_cpe1_epc1 } };
