Gian-Carlo Pascutto	454959a5aa	aacdec: Set the profile during decoding Previously the profile would not be set if the bitstream needs to be decoded to know the profile. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Michael Niedermayer	eab49f4fb5	Revert "aacdec: Reconfigure output as needed, disable pop_output_configuration()" This reverts commit `60dbf2eff9`. This is not needed anymore, Ticket 1694 has been fixed differently	12 years ago
Michael Niedermayer	8978c743fb	aacsbr: Check for envelope scalefactors overflowing This prevents various values from becoming stuck at NAN and output to become silent If someone knows a cleaner solution, thats welcome! Fixes Ticket2335 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Diego Biurrun	218aefce44	dsputil: Move LOCAL_ALIGNED macros to libavutil	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago

Alex Converse	9fb7e14635	aacdec: More robust output configuration. Save the old output configuration (if it has been used successfully) when trying a new configuration. If the new configuration fails to decode, restore the last successful configuration.	13 years ago
Reimar Döffinger	1ac606bae6	aacsbr: silence message for SBR extension "padding". Some files contain a few additional, all-0 bits. Check for that case and don't print incorrect "not supported" message. Fixes trac issue #836. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Alex Converse	b00307ecd0	aacsbr: Add a debug check to sbr_mapping. There have been multiple bugs caused by inconsistencies here. Based on an idea from Michael Niedermayer. CC: libav-stable@libav.org	13 years ago
Alex Converse	0cb93dacee	aac: Reset some state variables when turning SBR off This makes sure the reset flag gets set when SBR gets turned back on and sets control variables for unguided mode back to their defaults. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Alex Converse	17ce52912f	aacsbr: prevent out of bounds memcpy(). Fixes Libav Bug 195. This doesn't make the code handle sample rate or upsample/downsample change properly but this is still a good sanity check. Based on change by Michael Niedermayer.
