Lynne	8ecaa64b9b	aacdec_usac: respect tns_on_lr flag This was left out, and due to av_unused, forgotten about.	8 months ago
Lynne	25b848a0bd	aacdec_usac: correctly set and use the layout map	8 months ago
Lynne	ae495b56ff	aacdec_usac: remove fallback for custom maps with invalid position Not needed as every possible index is mapped.	8 months ago
Lynne	91ab17e2fe	aacdec_usac: tag LFE channels as such in the channel map Missed.	8 months ago
Lynne	62cd6d9e59	aacdec_usac: clean up nb_elems on error Require that there is a valid layout with a valid number of channels before accepting nb_elems. The value is required when flushing. Thanks to kasper93 for figuring it out.	8 months ago
Lynne	1c066867df	aac: define a new profile for USAC This allows users to determine whether a stream is USAC or not.	8 months ago
Lynne	7413b81e50	aacdec_usac: fix typo in debug message	8 months ago
Lynne	f4371029f8	aacdec_usac: fix off by one error check on channel numbers	8 months ago
Lynne	0d93e04bc6	aacdec_usac: error out on receiving too many channels for the current layout Verify that we have a correct number of channels.	8 months ago
Lynne	39826eacff	aacdec_usac: error out on too many elements USAC supports up to 64 audio channels, but puts no limit on the total number of extensions that may be present. Which may mean that there's a single audio channel, with 65 thousand extension elements. We assume that 64 elements is the maximum for now. So check the value.	8 months ago
Lynne	b70fdbde9c	aacdec_usac: prevent get_bits(0) in get_escaped_value Some calls to get_escaped_value() specify 0 bits as the third value. This would result in get_bits(0), which is not a correct usage of the get_bits API.	8 months ago
James Almer	4d59d58ea6	avcodec/aac/aacdec_usac: remove unnecessary cast Fixes "libavcodec/aac/aacdec_usac.c(543): error C2440: 'type cast': cannot convert from 'GetBitContext' to 'GetBitContext'" from msvc. Signed-off-by: James Almer <jamrial@gmail.com>	8 months ago
Lynne	18757b26bd	aacdec_usac: fix typo in fac_length The spec says: fac_length = (window_sequence==EIGHT_SHORT_SEQUENCE) ? ccfl/16 : ccfl/8; The length used was flipped for short vs long.	8 months ago
James Almer	d8ffd65bfd	avcodec/aac/aacdec_usac: remove call to realloc Must be one of the lavu wrappers instead. Signed-off-by: James Almer <jamrial@gmail.com>	8 months ago
Lynne	eee5fa0808	aacdec: add a decoder for AAC USAC (xHE-AAC) This commit adds a decoder for the frequency-domain part of USAC. What works: - Mono - Stereo (no prediction) - Stereo (mid/side coding) - Stereo (complex prediction) What's left: - SBR - Speech coding Known issues: - Desync with certain sequences - Preroll crossover missing (shouldn't matter, bitrate adaptation only)	8 months ago
