foo86	9e37cc1101	avcodec/dca: move bits per sample array to dca.c It will be used by the parser. This change avoids unwanted parser dependency on dcadata. Signed-off-by: James Almer <jamrial@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	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

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	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.

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	17 years ago
