Diego Biurrun	34150be515	build: Let the iac decoder depend on the imc decoder Almost all of the code is shared so there is little point in enabling one decoder without the other.	11 years ago
Diego Biurrun	8e0cf39faf	build: Let all MJPEG-related decoders depend on the MJPEG decoder These codecs compile all of the MJPEG code anyway, so there is little point in not enabling the MJPEG decoder directly. This also simplifies the dependency declarations for the MJPEG codec family.	11 years ago
Diego Biurrun	0a36988e48	build: Let AMV decoder depend on the SP5X decoder This codec compiles all of the SP5X code anyway, so there is little point in not enabling the decoder directly. This also simplifies the dependency declaration for the AMV decoder.	11 years ago

Hendrik Leppkes	3aca10bf76	latm: Always reconfigure if no extradata was set previously AAC LOAS can have new audio config objects in the stream itself. Make sure the decoder reconfigures itself when the first one arrives midstream. Bug-Id: 644 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Janne Grunau	6e4009d4cd	arm: dcadsp: implement decode_hf as external NEON asm	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	08e3ea60ff	x86: synth filter float: implement SSE2 version Timings for Arrandale: C SSE win32: 2108 334 win64: 1152 322 Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with the jmp destination being aligned. Unrolling for ARCH_X86_64 is a 20 cycles gain. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	57b1eb9f75	dcadsp: scan coefficients linearly in dca_lfe_fir This change is inspired by x86 asm where it frees a register. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	ad507d7907	x86: dcadsp: implement SSE lfe_dir Results for Arrandale/Windows: 32: 1670 -> 316 64: 728 -> 298 Signed-off-by: Janne Grunau <janne-libav@jannau.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
