Michael Niedermayer	55bd20a841	avcodec/dcadec: AVClass is const Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	12235a3ed2	avcodec/dcadec: print more details about errors Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	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 Easier to read, modify, and avoids relying on an outdated table.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
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

Michael Niedermayer	5d47850bbd	dcadec: skip QMF on unused channels When the extra rear channel is present but unused, the s->channel_order_tab[] value for that channel is -1. The QMF can be skipped for the extra channel, and doing so avoids an out-of-array read on s->samples_chanptr[].

Hendrik Leppkes	65219c3851	dca: map xxch side channels to AV_CH_SIDE_LEFT/RIGHT instead of REAR. This fixes decoding of certain 7.1 DTS-HD HRA files, as well as matches the spec better. Table 6-22 in the DTS spec labels the two channels "Left/Right surround on side", and not rear.
