Alex Converse	021914e27f	aacdec: Cleanup decode_ics_info. Remove unused function argument. Return an AVERROR. Don't zero out ICS on failure.	13 years ago
Reimar Döffinger	36be045ed7	Support "VLB " audio in NSV files. See samples/nsv/vlb_audio. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Alex Converse	5cd56e193f	aacdec: Use intfloat.h rather than local punning union.	13 years ago
Janne Grunau	d268b79e34	aac_latm: reconfigure decoder on audio specific config changes	13 years ago
Janne Grunau	fd095539d1	latmdec: fix audio specific config parsing Pass the correct size in bits to mpeg4audio_get_config and add a flag to disable parsing of the sync extension when the size is not known. Latm with AudioMuxVersion 0 does not specify the size of the audio specific config. Data after the audio specific config can be misinterpreted as sync extension resulting in random and wrong configs.	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
kaptnole	cb8db6423a	aacdec: Fix Sound fragments after seeking Fixes Ticket420 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	963f685535	aacdec: Fix PS in ADTS. Fixes File1.aac and Bug 80.	13 years ago
Michael Niedermayer	5a2b3f3a52	aacdec: Avoid unneeded reinit due to ADTS headers Fixes Ticket 662 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	bc2dd36740	aacdec: allow output reconfiguration on channel changes Locking the decoder against channel config changes in parse_adts_frame_header() seems to be unnecessary and streams with channel config changes are reported. The sample in http://roundup.libav.org/issue999 still works. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Justin Ruggles	71ccfb3f14	aac_latm: remove unneeded check for zero-size packet. This is already checked by avcodec_decode_audio3()	13 years ago

Janne Grunau	785f876cee	latm: avoid unnecessary reinit of the aac decoder	13 years ago
Janne Grunau	80e36425fb	aacdec: initialize sbr context only in new channel elements	13 years ago
Dustin Brody	9abc98737f	lavc: replace references to deprecated AVCodecContext.error_recognition to use AVCodecContext.err_recognition Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Michael Niedermayer	b4d0e7804d	aacdec:only overwrite configuration if theres a actual change. Fixes Ticket574 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	59a9a23581	lavc: use avpriv_ prefix for some mpeg4audio symbols used in lavf. Specifically, ff_mpeg4audio_sample_rates, ff_mpeg4audio_get_config and ff_copy_pce_data	13 years ago
Anton Khirnov	73ae27e17b	lavc: use avpriv_ prefix for ff_aac_parse_header(). It's used in lavf.	13 years ago
Michael Niedermayer	8daf04add4	aacdec: support chan config =1 stereo files Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	d12294304a	aacdec: fix undefined shifts Since nnz can be zero, this is needed to avoid a shift by 32. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	0bc5d4fd8b	aacdec: fix channel reconfigs on LATM Fixes Ticket200 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	b6aaa6d9a0	aacdec: Make aac-latm closer to the spec (not reading random data leading to random false configurations) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	9815039053	aacdec: disable locking code for parse_adts_frame_header() non zero chan config. This fixes changing channels It possibly might cause regressions but i cant avoid this without having a test case that needs the locking code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	44920d04ba	aac: Only set sample rate and object type from ADTS if output hasn't been configured. Long term it would be nice to support error resilient reconfiguration but right now setting this every frame does more harm than help. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Alex Converse	06d37fede4	aac: Set SBR and PS to unsignalled during headerless and ADTS initialization. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Alex Converse	d8425ed4af	aac: Only output configure if audio was found. Audio found is not triggered on a CCE because a CCE alone has no output. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Alex Converse	94d47382e0	aac: Don't attempt to output configure an invalid channel configuration.	14 years ago
Dustin Brody	680b1852ab	aac: propagate error return values for AV_LOG_ERROR-triggering events	14 years ago
Alex Converse	a6c49f18ab	aac: Remove some suspicious illegal memcpy()s from LTP.	14 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Alex Converse	a58858d60d	lavf: Cleanup try_decode_frame() logic. This fixes AAC playback in ffplay.	14 years ago
Reimar Döffinger	896e59758a	Move resetting of channels, sample_rate back to av_find_stream_info. Resetting it on codec init would incorrectly clear the values if av_find_stream_info was already run before, in particular breaking ffplay. This fixes trac tickets #213 and #262. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago
Benjamin Larsson	dafaef2fe1	Add support for aac streams in mp4/mov without extradata.	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
Carl Eugen Hoyos	06fd213eb6	Do not reset channel_layout to 0. The channel_layout may have been set by the demuxer.	14 years ago
Justin Ruggles	cef7d70181	aacdec: fix typo in scalefactor clipping check	14 years ago
Ronald S. Bultje	42da8ea8e8	LATM/AAC: Free previously initialized context on reinit. Fixes memory leaks which are the result of overwriting already-initialized MDCT contexts during context reinitialization, e.g. in valgrind fate-aac-latm_000000001180bc60. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Justin Ruggles	9aa8193a23	Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbis decoders. Based on patches by clsid2 in ffdshow-tryout.	14 years ago
Justin Ruggles	033a4a942a	aacdec: Use float instead of int16_t for ltp_state to avoid needless rounding.	14 years ago
Reimar Döffinger	6fd00e9dd9	aacdec: add decode_channel_map overread check All decode_channel_map calls together can easily read more data than the amount of padding available. Thus below patch adds an input length check before reading them. Fixes some invalid reads with sample from http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1138	14 years ago
Alex Converse	767848d761	aacdec: remove sf_scale and sf_offset. Instead, scalefactors are adjusted by the offset amount, removing the need for sf_scale, and the MDCT scales are adjusted to compensate for the higher scalefactors. Floating-point output will be handled by modifying the MDCT scales.	14 years ago
Justin Ruggles	6271794041	aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficient table values from the spec.	14 years ago
Alex Converse	d70fa4c423	Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets instead of hardcoding 200 everywhere.	14 years ago
Alex Converse	e4744b59aa	Large intensity stereo and PNS indices are legal. Clip them instead of erroring out. A magnitude of 100 corresponds to 2^25 so the will most likely result in clipped output anyway. None of the conformance streams fall in the range that need to be clipped.	14 years ago
Reimar Döffinger	26d5a4b6b4	aacdec: Allow selecting float output at runtime.	14 years ago

Alex Converse	187a537904	Convert some undefined 1<<31 shifts into 1U<<31. According to ISO 9899:1999 S 6.5.7/4: The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1× 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined.	14 years ago
Janne Grunau	d6f66edd65	Revert "aac_latm_dec: use aac context and aac m4ac" This reverts commit `36864ac354` since it breaks LATM decoding in ffplay.	14 years ago
