2013-11-26aacsbr: Add some const casts to silence warnings in ff_sbr_apply()Diego Biurrun
2013-11-04aacdec: Set the profile during decodingGian-Carlo Pascutto
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>
2013-03-14avcodec: av_log_missing_feature(1) ---> avpriv_request_sample()Diego Biurrun
2013-03-13av_log_missing_feature() ---> avpriv_report_missing_feature()Diego Biurrun
2013-02-09dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun
2013-01-22floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje
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.
2013-01-22floatdsp: move vector_fmul_add from dsputil to avfloatdsp.Ronald S. Bultje
2012-12-07AAC SBR: use AVFloatDSPContext's vector_fmulChristophe Gisquet
Around 5% speedup on the code block using 'vector_fmul_add's. Signed-off-by: Diego Biurrun <diego@biurrun.de>
2012-12-03aac: avoid a memcpy in sbr_qmf_analysisChristophe Gisquet
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>
2012-11-26aacdec: use float planar sample format for outputJustin Ruggles
2012-10-23Improve wording and spelling of av_log_missing_feature messages.Diego Biurrun
2012-04-17aacdec: More robust output configuration.Alex Converse
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.
2012-03-24aacsbr: Add a debug check to sbr_mapping.Alex Converse
There have been multiple bugs caused by inconsistencies here. Based on an idea from Michael Niedermayer. CC: libav-stable@libav.org
2012-03-24aac: Reset some state variables when turning SBR offAlex Converse
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
2012-03-08Revert "AAC SBR: group some writes."Ronald S. Bultje
This reverts commit ba36f14e5d34bcca6ecf77ba1c7512d1b51a9740. It broke decoding on x86-32 on some systems.
2012-03-07AAC SBR: group some writes.Christophe Gisquet
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2012-03-01aacsbr: use a swap index for the Y matrix rather than copy buffers.Christophe Gisquet
Signed-off-by: Alex Converse <alex.converse@gmail.com>
2012-01-28aacsbr: align some arraysMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-01-28aacsbr: move some simdable loops to function pointersMans Rullgard
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>
2012-01-11aacsbr: prevent out of bounds memcpy().Alex Converse
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>
2011-05-19Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbisJustin Ruggles
decoders. Based on patches by clsid2 in ffdshow-tryout.
2011-04-26aac: add headers needed for log2f()Michael Niedermayer
Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-03-19fft: remove inline wrappers for function pointersMans Rullgard
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>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-14aac: remove dead SBR input scalingAlex Converse
It has been unused since 9d06d7bce3babb82ed650c13ed13a57f6f626a71 Signed-off-by: Mans Rullgard <mans@mansr.com>
