* aacdec: do not mutate input packet metadatawm42017-03-09
| | | | | | | | | | | | | | | | | Apparently the demuxer outputs the wrong padding for HE-AAC (based on the raw sample rate, or so). aacdec contains a hack to adjust the muxer padding accordingly before it's used to trim the decoder output. This modified the packet side data, which in combination with the old decoding API would change the packet the user passed to the decoder. This is clearly not allowed, and it breaks running some gapless fate tests with "-fflags +keepside" applied (without keepside, the packet metadata is typically newly allocated, essentially making a copy and not modifying the user's input packet). This should probably be fixed in the demuxer (and consequently also the muxer), but for now only fix the immediate problem. Regression since 946ed78f5f8 (2012).
* aacdec: When ignoring a PCE restore the previous configAlex Converse2017-02-21
| | | | This is related to, but doesn't solve ticker 6152.
* imdct15: rename to mdct15 and add a forward transformRostislav Pehlivanov2017-02-14
| | | | | | | Handles strides (needed for Opus transients), does pre-reindexing and folding without needing a copy. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* aac_latm: Align inband PCE to the start of the payloadAlex Converse2017-02-13
| | | | | | | | | | | A strict reading of the spec seems to imply that it should be aligned to the start of the element instance tag, but that would break all of the samples with PCEs. It seems like a well formed LATM stream should have its PCE in the ASC rather than inband. Fixes ticket 4544
* aacsbr: Associate SBR data with AAC elements on initAlex Converse2017-02-13
| | | | | | Quiets some log spam on pure upsampling mode. Fixes ticket 5163.
* aac_latm: Allow unaligned AudioSpecificConfigAlex Converse2017-02-13
| | | | Fixes ticket 4730
* aacdec: Rename elem_type_prev to che_prev_type.Alex Converse2016-12-08
| | | | | It describes the type of the previous che element (SCE, CPE, CCE, or LFE) and does not reflect non-che elements.

* aac: temporarily un-share aac_table_init AVOnce variableRostislav Pehlivanov2015-11-27
| | | | | | | AAC-Fixed decoder segfaulted. This commit makes the aac encoder and decoder init the table twice in case of transcoding again. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* aacenc: make threadsafeRostislav Pehlivanov2015-11-27
| | | | | | | | Since the ff_aac_tableinit() can be called by both the encoder and the decoder (in case of transcoding) this commit shares the AVOnce variable to prevent this. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* avcodec/aacdec_fixed: Fix preparation for resamplerNedeljko Babic2015-07-29
| | | | | | | | | | | | 2nd channel makes sense only for CPE type. Skip 2nd channel in preparation for resampler (in spectral_to _sample()) depending on block type.

* avcodec/aac_fixed: Fix a bug in spectral_to_sample()Nedeljko Babic2015-07-28
| | | | | | | | | | | | | | There was fixed number of loops (2048) in preparation for resampler, so when number of samples is smaller than this, there would be an overflow on ret_buf. For some reason this behavior popped out only under valgrind with --disable-memory-poisoning option. This is now fixed and number of loops depends on actual number of samples.
