Michael Niedermayer	47313bbb5f	avcodec/dcadec: remove fishy FFMAX() These where intended to maintain the previous behavior before dca_dmix_code() but it is unclear (to me) which way is correct and no sample seem to trigger the case, also they are incomplete for the purprose of error checking Found-by: Niels Möller <nisse@lysator.liu.se> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Niels Möller	b3d905b702	dcadec: Delete redundant init_get_bits call No initialization is needed in dca_decode_frame, because the next thing it does is calling dca_parse_frame_header, which takes care of the needed initialization. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Christophe Gisquet	4cb6964244	dcadec: simplify decoding of VQ high frequencies The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.	11 years ago
Janne Grunau	7686afd049	dca: factorize scaling in inverse ADPCM Based on a patch from Christophe Gisquet. Unrolling of the m == 0 case avoids a possible use of the uninitilized value sum when s->predictor_history is not set. I failed to find a sample for it. It also reduced the cycle count from 220 to 150 on sandy bridge, x86_64 linux, gcc 4.8.2 compared to his patch.	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

Christophe Gisquet	45854df9a5	dcadsp: split lfe_dir cases The x86 runs short on registers because numerous elements are not static. In addition, splitting them allows more optimized code, at least for x86. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
