Christophe Gisquet	5fdbfcb5b7	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. Arm asm changes by Janne Grunau. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	5b59a9fc61	x86: dcadsp: implement int8x8_fmul_int32 For the callable function (as opposed to the inline one): C SSE SSE2 SSE4 Win32: 47 42 29 26 Win64: 30 33 25 23 The SSE version is neither compiled nor set for ARCH_X86_64, as the inlinable function takes over.

Christophe Gisquet	2bd44cb705	dcadsp: add int8x8_fmul_int32 to dsp context It is currently declared as a macro who is set to inlinable functions, among which a Neon and a default C implementations. Add a DSP parameter to each inline function, unused except by the default C implementation which calls a function from the DSP context. On an Arrandale CPU, gain for an inlined SSE2 function vs. a call: - Win32: 29 to 26 cycles - Win64: 25 to 23 cycles Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Tim Walker	30d70e79a6	dcadec: set AV_FRAME_DATA_MATRIXENCODING side data.	11 years ago
Tim Walker	6bfdb2de88	dcadec: set the output channel mode more accurately. When downmixing 2.1 to 2-channel, if the 2.0 portion is Lt/Rt, sum-difference or dual mono, the actual output will be the same (with the LFE either mixed-in or discarded). Also, when downmixing an arbitrary layout to 2-channel, if the bitstream contains custom downmix coefficients targeting Lt/Rt, then the output will be Lt/Rt rather than regular Stereo.	11 years ago

Tim Walker	3c8507a845	dcadec: add disable_xch private option. This supplements the deprecated request_channels-based control of XCh decoding. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	220494ad0b	dcadec: treat all 2-channel modes as Stereo in dca_downmix. The check for (prim_channels > 2) before calling dca_downmix made these cases unreachable, but now 2.1 layouts will go through the downmix code. Having dual mono, Lt/Rt and sum-difference layouts print errors when regular Stereo doesn't seems pointless. Signed-off-by: Anton Khirnov <anton@khirnov.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	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
Tim Walker	25609b63d2	dcadec: store the stereo downmix coefficients as float in the DCAContext. The 7-bit codes previously used are absent from the ETSI 102 114 V1.4.1 spec. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
