* aacdec: Fix SCE parity check.Michael Niedermayer2012-03-09
| | | | | | | | | An unpaired SCE preceding a CPE only makes sense for front SCEs preceding the first CPE. Split from FFmpeg commit a8d67efa53dae1d14614e3a7bd4e77e4eab066ab Signed-off-by: Alex Converse <alex.converse@gmail.com>
* aacdec: Fix out of array writes (stack).Michael Niedermayer2012-03-09
| | | | | | | | | | | | Set the element to channel vector (e2c_vec) size to be the maximum number of aac channel elements. This makes it slightly larger than it needs to be because CCEs are never mapped to output channel locations. Also add a check that all input tags (legal or not) will fit.

|
* 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

| | | | | | Remove unused function argument. Return an AVERROR. Don't zero out ICS on failure.

|
* 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

* 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>

* 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.
