Diego Biurrun	218aefce44	dsputil: Move LOCAL_ALIGNED macros to libavutil	12 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	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

Ronald S. Bultje	93b53ffb1a	dca: don't use av_clip_uintp2(). The argument is not a literal, thus causing the ARM v6 or later builds to break.	13 years ago

Shitiz Garg	f37b4efe03	dca: K&R formatting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 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
Justin Ruggles	aae6eead6a	dca: return error if the frame header is invalid	13 years ago
Justin Ruggles	f44059d260	dca: return proper error codes instead of -1	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
Mans Rullgard	a92a1b93b4	dca: use vector_fmac_scalar from dsputil 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.

Diego Biurrun	be73d76b34	cosmetics: fix some then/than typos	14 years ago
Justin Ruggles	e6c52cee54	Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample(). av_get_bits_per_sample_fmt() is deprecated.	14 years ago

Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Anssi Hannula	7e06e0ede3	dca: use EXT_AUDIO_ID field to determine core extensions This avoids the core substream extensions scan when the EXT_AUDIO_ID field indicates no extensions or only unsupported extensions. The scan is done only if the value of EXT_AUDIO_ID is unknown or indicates a present XCh extension which we can decode. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Anton Khirnov	c2fcd0a7a4	Replace remaining occurrences of deprecated CH_* with AV_CH_* Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
