* Bug 7170947 Update AAC codecJean-Michel Trivi2012-10-021-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Fraunhofer: * AAC Decoder - Stick to the written MPEG standard instead of the MPEG reference software in terms of reference level normalization. Always set the program reference level equal to the target level. This disables level normalization using a default level for streams without embedded metadata. Modified file(s): libAACdec\src\aacdec_drc.cpp - Fix downmix channel assignment when using a WAV output channel ordering. Modified file(s): libPCMutils\src\pcmutils_lib.cpp - Retain signal accuracy and prevent LSB alteration when no level correction needs to be done.

Modified file(s): libAACdec\src\aacdec_drc.h libAACdec\src\aacdecoder.cpp * AAC-Encoder - Prevent potential overflow in energy calculation after TNS processing. Modified file(s): libAACenc\src\band_nrg.cpp - Added saturation for number of relevant lines which are used in pe calculation. Modified file(s): libAACenc\src\line_pe.cpp - Removed obsolete files. Deleded file(s): libAACenc\src\tns_param.h libAACenc\src\tns_param.cpp * FDK-Library - Added x86 Count Leading Zeros intrinsic. Modified file(s): libFDK\include\clz.h Added file(s): libFDK\include\x86\clz_x86.h - Fixed compilation for MIPS GCC-4.4 and higher.

* Don't zero out spec coeffs before doing the final IMDCT.John Grossman2012-09-121-4/+1
| | | | | | | | | | | | | | | | | Addresses bug 7140347. When flushing the decoder, you need to make sure to zero out any lingering spectral coefficients as well as zero out the overlap buffer state after decoding the final access unit. Zeroing out the spec coefficients *before* you decode the last block, however, seems like a mistake. If the final block contains any useful information for the stream, then you end up outputting the overlap portion of the second to last decoded block combined with zeros. Because of the shape of the second to last block's windows, this results in what appears to be a fade out, but actually is a zero'ed out final block.
