2011-02-17Merge libavcore into libavutilReinhard Tartler
Done to keep ABI compatible. Otherwise this is just silly

2011-02-04Separate format conversion DSP functions from DSPContext.Justin Ruggles
This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit c73d99e672329c8f2df290736ffc474c360ac4ae)

2011-01-28Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit d36beb3f6902b1217beda576aa18abf7eb72b03c)

2011-01-23dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRAAnssi Hannula
DTS-HD HRA streams do not always have an XBR extension in the extension substream. Instead they can have only XXCh and X96 extensions in there and still be considered DTS-HD HRA. This is also confirmed with Onkyo TX-SR607 receiver which recognizes such a stream as HiRes Audio. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 8f4a5d225c6cd65c5f306a200da991f8a59a439a)

2010-11-21Use the new libavcore audio channel API.Stefano Sabatini
This also allows to remove a linking dependency of libavfilter on libavcodec. Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-11-12Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enumStefano Sabatini

2010-10-03Add the CODEC_CAP_CHANNEL_CONF capability code and addBenjamin Larsson
that flag to the dca codec. This capability when set will make sure the codec will initialize the channel configuration instead of trusting the container. This fixes issue 2137 and issue 850. Originally committed as revision 25320 to svn://svn.ffmpeg.org/ffmpeg/trunk

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 22872 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-13DCA: optimise dca_subsubframe()Måns Rullgård
8% faster overall on Cortex-A8. Originally committed as revision 22871 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-13DCA: break out lfe_interpolation_fir() inner loops to a functionMåns Rullgård
This enables SIMD optimisations of this function. Originally committed as revision 22861 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12DCA: use FASTDIV in decode_blockcode()Måns Rullgård
Originally committed as revision 22855 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12DCA: simplify lfe_interpolation_fir()Måns Rullgård
This reorders the lfe_fir tables, and drops the mirrored half, such that the loops in lfe_interpolation_fir() can be simplified. The new loop structure should be easier to implement with SIMD. Static data size is reduced by 2kB. 3% faster on Cortex-A8. Originally committed as revision 22849 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12DCA: use a local variable for loop boundaryMåns Rullgård
This prevents gcc reloading the value from memory on each iteration of the loop. Originally committed as revision 22848 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12DCA: use some type-punning in qmf_32_subbands()Måns Rullgård

2010-04-10Make synth_filter a function pointerMåns Rullgård
Originally committed as revision 22827 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-10DCA: align some arraysMåns Rullgård
Optimised implementations of the synth filter will require these arrays 16-byte aligned. Originally committed as revision 22826 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-31Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini
is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Move FFT parts from dsputil.h to fft.hMåns Rullgård
Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård
These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-26Fixed a segfault in the DCA decoder with corrupted streams.Laurent Aimar
It happens when the number of channels defined by DCAContext:acmod is lower than DCAContext:prim_channels. In this case, dca_subsubframe() will call qmf_32_subbands() using s->channel_order_tab[] entries equal to -1. Originally committed as revision 22083 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-22Move array specifiers outside DECLARE_ALIGNED() invocationsMåns Rullgård
Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk
