From 5016eb7f6582fbb2d72d79be782325a12df08864 Mon Sep 17 00:00:00 2001 From: Jean-Michel Trivi Date: Tue, 27 Aug 2013 16:28:09 -0700 Subject: [PATCH] Decoder stability, sanity checks improvements * AAC-Decoder - Improved PCE handling for saver (re-)configuration and metadata processing. Modified file(s): libAACdec/src/aacdecoder.cpp libAACdec/src/aacdecoder_lib.cpp - Transport layer changes (config found) -> to be evaluated. Modified file(s): libMpegTPDec/include/tpdec_lib.h libMpegTPDec/src/tpdec_latm.h libMpegTPDec/src/version libMpegTPDec/src/tpdec_asc.cpp libMpegTPDec/src/tpdec_lib.cpp libMpegTPDec/src/tpdec_adts.cpp libMpegTPDec/src/tpdec_latm.cpp libSYS/include/FDK_audio.h libSYS/src/genericStds.cpp - Enable concealment state machine to skip states if the corresponding parameter is set to zero. Modified file(s): libAACdec/src/conceal.cpp - Add some more sanity checks to avoid segmentation faults especially when setting dynamic API params. Modified file(s): libAACdec/src/aacdecoder_lib.cpp - Fix to do a fail-safe initialization of IMDCT for all channels even with corrupt streams. Modified file(s): libAACdec/src/aacdecoder.cpp - HCR decoder fix (remove warnings). Modified file(s): libAACdec/src/block.cpp - Fix border calculation in SBR decoder's LPP transposer patch determination. Modified file(s): libSBRdec/src/env_dec.cpp libSBRdec/src/sbrdecoder.cpp libSBRdec/src/lpp_tran.cpp Bug 9428126 Change-Id: Ib415b702b88a7ec8e9a55789d79cafb39296d26b --- libAACdec/src/aacdecoder.cpp | 144 ++++++---- libAACdec/src/aacdecoder_lib.cpp | 26 +- libAACdec/src/block.cpp | 14 +- libAACdec/src/conceal.cpp | 102 ++++--- libMpegTPDec/include/tpdec_lib.h | 21 ++ libMpegTPDec/src/tpdec_adts.cpp | 4 +- libMpegTPDec/src/tpdec_asc.cpp | 147 +++++++++- libMpegTPDec/src/tpdec_latm.cpp | 20 +- libMpegTPDec/src/tpdec_latm.h | 13 +- libMpegTPDec/src/tpdec_lib.cpp | 444 ++++++++++++++++++++----------- libMpegTPDec/src/version | 2 +- libSBRdec/src/env_dec.cpp | 4 +- libSBRdec/src/lpp_tran.cpp | 18 +- libSBRdec/src/sbrdecoder.cpp | 10 +- libSYS/include/FDK_audio.h | 6 + libSYS/src/genericStds.cpp | 2 +- 16 files changed, 683 insertions(+), 294 deletions(-) diff --git a/libAACdec/src/aacdecoder.cpp b/libAACdec/src/aacdecoder.cpp index 3d00d34..3a2a561 100644 --- a/libAACdec/src/aacdecoder.cpp +++ b/libAACdec/src/aacdecoder.cpp @@ -373,7 +373,7 @@ static AAC_DECODER_ERROR CDataStreamElement_Read ( { INT readBits, dataBits = count<<3; - + /* Move to the beginning of the data junk */ FDKpushBack(bs, dataStart-FDKgetValidBits(bs)); @@ -394,23 +394,26 @@ static AAC_DECODER_ERROR CDataStreamElement_Read ( \brief Read Program Config Element \bs Bitstream Handle - \count Pointer to program config element. + \pTp Transport decoder handle for CRC handling + \pce Pointer to PCE buffer + \channelConfig Current channel configuration + \alignAnchor Anchor for byte alignment - \return Error code + \return PCE status (-1: fail, 0: no new PCE, 1: PCE updated, 2: PCE updated need re-config). */ -static AAC_DECODER_ERROR CProgramConfigElement_Read ( +static int CProgramConfigElement_Read ( HANDLE_FDK_BITSTREAM bs, HANDLE_TRANSPORTDEC pTp, CProgramConfig *pce, - UINT channelConfig, - UINT alignAnchor ) + const UINT channelConfig, + const UINT alignAnchor ) { - AAC_DECODER_ERROR error = AAC_DEC_OK; + int pceStatus = 0; int crcReg; /* read PCE to temporal buffer first */ C_ALLOC_SCRATCH_START(tmpPce, CProgramConfig, 1); - + CProgramConfig_Init(tmpPce); CProgramConfig_Reset(tmpPce); @@ -421,22 +424,43 @@ static AAC_DECODER_ERROR CProgramConfigElement_Read ( transportDec_CrcEndReg(pTp, crcReg); if ( CProgramConfig_IsValid(tmpPce) - && ( (channelConfig == 6 && (tmpPce->NumChannels == 6)) - || (channelConfig == 5 && (tmpPce->NumChannels == 5)) - || (channelConfig == 0 && (tmpPce->NumChannels == pce->NumChannels)) ) - && (tmpPce->NumFrontChannelElements == 2) - && (tmpPce->NumSideChannelElements == 0) - && (tmpPce->NumBackChannelElements == 1) && (tmpPce->Profile == 1) ) - { /* Copy the complete PCE including metadata. */ - FDKmemcpy(pce, tmpPce, sizeof(CProgramConfig)); + { + if ( !pce->isValid && (channelConfig > 0) ) { + /* Create a standard channel config PCE to compare with */ + CProgramConfig_GetDefault( pce, channelConfig ); + } + + if (pce->isValid) { + /* Compare the new and the old PCE (tags ignored) */ + switch ( CProgramConfig_Compare( pce, tmpPce ) ) + { + case 1: /* Channel configuration not changed.
