Daniil Cherednik	c2500d62c6	dcaenc: Implementation of Huffman codes for DCA encoder Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
foo86	a0f76b825c	avcodec/dca: move EXSS sampling frequency arrays to dca.c Avoids unwanted parser dependency on dcadata. Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	64fe1eebdd	avcodec/dca: use LUT for LBR frequency ranges Values for unsupported frequencies > 48000 Hz are still included (parser will make use of them). Also convert sampling frequencies array to unsigned. Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	6c44696b3d	avcodec/dca: add DTS Express (LBR) decoder Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	2df7d4fa45	avcodec/dca: move huffman data into separate object file Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	b286ff69c0	avcodec/dcaenc: move channel reordering tables to dcaenc.h DCA core decoder no longer uses fixed tables for channel reordering. Move them into private encoder header (and drop ff_dca_ prefix). Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	9a0a3bbeaa	avcodec/dca: add more tables	9 years ago
foo86	4608996772	avcodec/dca: remove old decoder Remove all files and functions which are not going to be reused, and disable all functions and FATE tests temporarily which will be.	9 years ago

Alexandra Hájková	2008f76054	dca: remove unused decode_hf function and quant_d tables They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.	9 years ago

Diego Biurrun	3a651f599a	dca: Move data tables from a header to an object file This allows sharing them with the DCA XLL extension w/o duplication.	10 years ago
Diego Biurrun	65df9904ce	dca: Add array sizes to array declarations	10 years ago
Michael Niedermayer	8123e19e61	avcodec/dcadec: Move remaining tables to dcadata.h Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Gabriel Dume	45ff7c93dd	dca: K&R formatting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	10 years ago
Niels Möller	6b7b8585d7	dca: Convert dca_dmixtable to integers Also include zero in the table, eliminating a special case in the decoder. Signed-off-by: Niels Möller <nisse@southpole.se> Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Christophe Gisquet	87ec849fe9	dcadec: remove scaling in lfe_interpolation_fir The scaling factor is constant so it is faster to scale the FIR coefficients in the tables during compilation. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Tim Walker	aaa44d0299	dca: support mixing LFE in dca_downmix. Embedded downmix coefficients can use this. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	149438cfe5	dca: improve default stereo downmix coefficients. Previous coefficients were producing a non-normalized, incorrect Lt/Rt downmix. The new coefficients produce a standard Lo/Ro downmix with 3dB attenuation. This should match the typical default coefficients used by DTS encoders. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	44b17d794a	dca: extract core substream's embedded downmix coeffcient codes, if present. As per ETSI TS 102 114 V1.4.1 specification. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	27245b4e1b	dca: remove embedded downmix coefficient extraction. It was based on an old, seemingly incorrect specification, so default coefficients were always used anyway. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	b6d5e6aa10	dca: convert dca_default_coeffs to float. Easier to read, modify, and avoids relying on an outdated table. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Diego Biurrun	9e4bca16f8	dca: Move tables used outside of dcadec.c to a separate file.	12 years ago
Nick Brereton	cd8bef969a	Generate channel layout, reordering for DTS-XXCH extension and, undo embedded downmixes Reviewed-by: Benjamin Larsson <benjamin@southpole.se> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Måns Rullgård	e168a5567a	DCA: 16-byte-align lfe_fir tables Originally committed as revision 22862 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	766fefe8e2	DCA: simplify lfe_interpolation_fir() 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	15 years ago
Jai Menon	96561c12c5	DECLARE_ALIGNED usage requires #inclusion of 'mem.h'. Originally committed as revision 22838 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	38d52f3ea3	DCA: align some arrays 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	15 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	99ed41a808	Fix filenames in Doxygen comments. Originally committed as revision 16811 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alexander E. Patrakov	3fc45bdcf0	fir_32bands_perfect[] contents were mixed, restore original order Patch by Alexander Patrakov ($lastname <whirlpool> gmail.com) Thread: dcadata.h: fir_32bands_perfect[] is wrong Originally committed as revision 14964 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
