* aacsbr: Fix type for index variableVittorio Giovara2015-03-17
| | | | | | Prevents unsigned overflow and variable truncation. Bug-Id: CID 603186
* aacsbr: silence message for SBR extension "padding".Reimar Döffinger2015-02-03
| | | | | | | | | Some files contain a few additional, all-0 bits. Check for that case and don't print incorrect "not supported" message. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Alex Converse <alex.converse@gmail.com>
* aacsbr: always initialize max_qmf_subbandsVittorio Giovara2014-11-24

* aacsbr: Add some const casts to silence warnings in ff_sbr_apply()Diego Biurrun2013-11-25

* aacdec: Set the profile during decodingGian-Carlo Pascutto2013-11-04
| | | | | | | 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>
* avcodec: av_log_missing_feature(1) ---> avpriv_request_sample()Diego Biurrun2013-03-13

* av_log_missing_feature() ---> avpriv_report_missing_feature()Diego Biurrun2013-03-13

* dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun2013-02-08
|
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | 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.
* floatdsp: move vector_fmul_add from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
|
* AAC SBR: use AVFloatDSPContext's vector_fmulChristophe Gisquet2012-12-07
| | | | | | Around 5% speedup on the code block using 'vector_fmul_add's. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* aac: avoid a memcpy in sbr_qmf_analysisChristophe Gisquet2012-12-02
| | | | | | | Swapping buffer indices allows saving one memcpy that accounts for 1% of the runtime, according to oprofile. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* aacdec: use float planar sample format for outputJustin Ruggles2012-11-25
|
* Improve wording and spelling of av_log_missing_feature messages.Diego Biurrun2012-10-23
|
* aacdec: More robust output configuration.Alex Converse2012-04-16
| | | | | | 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.
* aacsbr: Add a debug check to sbr_mapping.Alex Converse2012-03-23
| | | | | | | | There have been multiple bugs caused by inconsistencies here. Based on an idea from Michael Niedermayer. CC: libav-stable@libav.org
* aac: Reset some state variables when turning SBR offAlex Converse2012-03-23
| | | | | | | | 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
* Revert "AAC SBR: group some writes."Ronald S. Bultje2012-03-07
| | | | | This reverts commit ba36f14e5d34bcca6ecf77ba1c7512d1b51a9740. It broke decoding on x86-32 on some systems.

| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacsbr: move some simdable loops to function pointersMans Rullgard2012-01-28
| | | | | | | | This prepares for assembly optimisations by moving the most time-consuming loops to functions called through pointers in a new context. Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacsbr: prevent out of bounds memcpy().Alex Converse2012-01-10
| | | | | | | | | | | 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. Signed-off-by: Alex Converse <alex.converse@gmail.com>
* Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbisJustin Ruggles2011-05-18

| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* fft: remove inline wrappers for function pointersMans Rullgard2011-03-19
| | | | | | | This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>
