* aac: Wait to know the channels before allocating frameLuca Barbato2015-06-07
| | | | | | | | The channel configuration can be delivered only by the PCE, try to parse it first and not try to decode until a channel configuration is set. CC: libav-stable@libav.org
* aac: Support channel configurations 11 and 12Sebastian Dröge2015-06-07
| | | | | | | | | | | These are defined in ISO/IEC 14496-3:2009/PDAM 4 for 6.1 and 7.1. It also defines another 7.1 layout with configuration 14, that one is not added here for now. 11: 3/3.1 FC FL+FR BL+BR BC LFE 12: 3/2/2.1 FC FL+FR SiL+SiR BL+BR LFE Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* aac: correctly map 7.1ch-wide AAC from FDK AAC encodernu7742015-06-07
| | | | | | | | | | FDK AAC encoder outputs SCE(front)+CPE(front)+CPE(back)+CPE(back) on MODE_7_1_REAR_SURROUND configuration. Since decoder couldn't properly map 4 back channels, decoding failed unless -request_channel_layout 0x8000000000000000 has been specified. Now we treat first CPE(back) as CPE(side) on channel mapping. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* aac: Correctly map multichannel ADTS AAC with non-zero channel_config + PCEnu7742015-06-03
| | | | | | | | | | | | | | | The decoder assigns channels using default channel configuration for 5.1ch when it parses an ADTS frame header using consecutive channel ids. When a PCE comes, it reassigns channels using PCE configuration using directly the ids provided. They can be arbitrary. Always use consecutive channel ids to avoid decoding glitches due spurious reconfigurations due the channel ids mismatch between the two otherwise-identical channel maps.

* aacdec: consistently use avctx for logging in decode_eld_specific_configAndreas Cadhalpun2015-04-19
| | | | | | ac may be NULL and then accessing ac->avctx results in a segmentation fault. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
* lavc: Replace av_dlog and tprintf with internal macrosVittorio Giovara2015-04-19
|
* aac: Relax reserved_bit validationVittorio Giovara2015-03-04
| | | | | | | | | | | Although the specification mandates this bit to zero, it may happen that software tools incorrectly flip it to one, invalidating a possibly valid stream. Relax this restriction, by failing only when AV_EF_BITSTREAM is set. This behaviour is similar to aac decoders in Firefox and Quicktime. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavc: remove unused traces of fmtconvert usageAnton Khirnov2015-02-28
| | | | | Those decoders have been switched to float output and so do not use fmtconvert anymore.
* aacdec: Support for ER AAC ELD 480.Alex Converse2015-02-03

* aac: Simplify decode_mid_side_stereoLuca Barbato2014-12-02
| | | | | Might spare few cycles if the compiler is naive and makes the function more readable.
* aacdec: avoid an out-of-bounds writeVittorio Giovara2014-11-24
| | | | | | | Also move the check in the case it is actually used. CC: libav-stable@libav.org Bug-Id: CID 1087090

* latm: Always reconfigure if no extradata was set previouslyHendrik Leppkes2014-02-28
| | | | | | | | | | AAC LOAS can have new audio config objects in the stream itself. Make sure the decoder reconfigures itself when the first one arrives midstream. Bug-Id: 644 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* aacdec: set AVFrame sample_rateJohn Stebbins2014-02-12
| | | | | | AVFrame.sample_rate is set in ff_get_buffer, but aacdec calls ff_get_buffer before the samplerate is known. So it needs to be set again before returning the frame.
* aac: Fix low delay windowing.Alex Converse2014-01-04
| | | | AAC LD uses a low overlap sine window instead of a KBD window.

* aacdec: Set the profile during decodingGian-Carlo Pascutto2013-11-04
