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 Easier to read, modify, and avoids relying on an outdated table.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

Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 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[].

Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Justin Ruggles	8ac0f6767b	dcadec: allow the decoder to change the channel layout mid-stream	12 years ago
Justin Ruggles	61d5313d94	dca: allocate a secondary buffer for extra channels when downmixing The output AVFrame buffer only has data for the downmix channels. Fixes a segfault when decoding dca with request_channels == 2.	12 years ago

Alex Converse	999e7ebd23	dca: Replace oversized unused get_bits() with skip_bits_long().	13 years ago
Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	00a856e3f9	dca: ARMv6 optimised decode_blockcode() This is a hand-tuned version of the code with impossible parts of the FASTDIV function ommitted. 2-5% faster overall on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	272fcc32bb	dca: handle errors from dca_decode_block() Return error if core block decoding fails. Do not enable XCh if XCh extension block decoding fails.	13 years ago

Mans Rullgard	bf00a73ace	dca: clear inactive subbands only once in qmf_32_subbands() Writing zeros to the high entries in the array need only be done once as the cutoff position is constant throughout the loop. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

John Stebbins	49c7006c7e	dca: set AVCodecContext frame_size for DTS audio Set the frame size when decoding DTS audio. This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly inaccurate frame duration estimate.
