2018-04-19aac: Rework extradata parsing codeVittorio Giovara
- enable the parsing code - use the new buffer instead of replacing the context one - do not push/pop configuration, just discard the exiting one - propagate errors correctly
2018-02-22Parse and drop gain control data, so that SSR packets decode.Dale Curtis
This will result in poor quality audio for SSR streams, but they will at least demux and decode without error; partially fixing ticket #1693. This pulls in the decode_gain_control() function from the ffmpeg summer-of-code repo (original author Maxim Gavrilov) at svn://svn.mplayerhq.hu/soc/aac/aac.c with some minor modifications and adds AOT_AAC_SSR to decode_audio_specific_config_gb().

2017-03-09aacdec: do not mutate input packet metadatawm4
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).

2017-02-13aac_latm: Align inband PCE to the start of the payloadAlex Converse
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

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.
