* aacdec: Support stereo streams that erroneously signal predefined channel ↵Michael Niedermayer2012-02-28
| | | | | | | | | | | configuration 1 (mono). [alex.converse@mgail.com] Move code to get_che() Update for AAC new channel configuration interface Only set chan_config if output_configure succeeds. Signed-off-by: Alex Converse <alex.converse@gmail.com>
* aacdec: Reshuffle functions so get_che() can call ↵Alex Converse2012-02-28

* aacdec: Support native channel layout when requested.Alex Converse2012-02-09
|
* aacdec: Try to sniff a reasonable channel layout for PCE based configurations.Alex Converse2012-02-09
| | | | This changes the output order of multichannel PCE based streams.
* aacdec: Remove incorrect comment.Alex Converse2012-02-08
| | | | It was only correct when element ids met very specific criteria.
* aacdec: Simplify output configuration.Alex Converse2012-02-08
|
* latmdec: Check AudioSpecificConfig length before decoding extradata.Alex Converse2012-01-11
| | | | | | | This is different than a normal get_bits() over read because decode_audio_specific_config() creates its own GetBitContext. Fixes Bug 170.
* aacdec: Turn off PS for multichannel files that use PCE based configs.Alex Converse2012-01-09
| | | | Fixes al_sbr_cm_48_5.1.mp4.

| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* aacdec: Cleanup decode_ics_info.Alex Converse2011-12-20
| | | | | | Remove unused function argument. Return an AVERROR. Don't zero out ICS on failure.
* aacdec: Use intfloat.h rather than local punning union.Alex Converse2011-12-12
|
* aac_latm: reconfigure decoder on audio specific config changesJanne Grunau2011-12-03
|
* latmdec: fix audio specific config parsingJanne Grunau2011-12-03
| | | | | | | | | 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.
* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* aacdec: Fix PS in ADTS.Alex Converse2011-11-22
| | | | Fixes File1.aac and Bug 80.
* aacdec: allow output reconfiguration on channel changesMichael Niedermayer2011-10-28
| | | | | | | | | | 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>
* aac_latm: remove unneeded check for zero-size packet.Justin Ruggles2011-10-26
| | | | This is already checked by avcodec_decode_audio3()

* lavc: use avpriv_ prefix for some mpeg4audio symbols used in lavf.Anton Khirnov2011-10-20
| | | | | Specifically, ff_mpeg4audio_sample_rates, ff_mpeg4audio_get_config and ff_copy_pce_data
* lavc: use avpriv_ prefix for ff_aac_parse_header().Anton Khirnov2011-10-20
| | | | It's used in lavf.
* aacdec: fix undefined shiftsMans Rullgard2011-10-08
| | | | | | Since nnz can be zero, this is needed to avoid a shift by 32. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* aac: Only output configure if audio was found.Alex Converse2011-08-18
| | | | | | Audio found is not triggered on a CCE because a CCE alone has no output. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* aac: Remove some suspicious illegal memcpy()s from LTP.Alex Converse2011-08-01
|
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* lavf: Cleanup try_decode_frame() logic.Alex Converse2011-07-13
| | | | This fixes AAC playback in ffplay.

* Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample().Justin Ruggles2011-06-20

* LATM/AAC: Free previously initialized context on reinit.Ronald S. Bultje2011-05-20
| | | | | | | | 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>

* aacdec: remove sf_scale and sf_offset.Alex Converse2011-04-27
| | | | | | | 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.
