Reimar Döffinger	1d130328ed	aacdec: update debug code to always print the processed data. When decoding LATM, this function will not process extradata but a different buffer. It seems this was forgotten to update when LATM support was added. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Diego Biurrun	3dde147ff9	cosmetics: Consistently place static, inline and av_cold attributes/keywords.	13 years ago

Michael Niedermayer	744dd1d356	aacdec: Fix SCE parity check. An unpaired SCE preceding a CPE only makes sense for front SCEs preceding the first CPE. Split from FFmpeg commit `a8d67efa53` Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Michael Niedermayer	d53fe096e4	aacdec: Fix out of array writes (stack). 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. Split from FFmpeg commit `a8d67efa53` Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Michael Niedermayer	a8d67efa53	aacdec: Fix out of array writes (stack). This fixes an issue in the code to check the size that will be written to match the actual code writing. In the long term it would make sense to change this so the counting and writing code are the same so they dont need to be kept in sync. It also increases the array size, which was too small either way and adds a redudnant saftey check. This issue does not affect any FFmpeg release as it has been introduced Jan 31 which is narrowly after our last release. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	956fb91e03	aacdec: Support stereo streams that erroneously signal predefined channel configuration 1 (mono). [alex.converse@mgail.com] Move code to get_che() Update for AAC new channel configuration interface Only set chan_config if output_configure succeeds.

Alex Converse	b5fc571e4f	latmdec: Check AudioSpecificConfig length before decoding extradata. This is different than a normal get_bits() over read because decode_audio_specific_config() creates its own GetBitContext. Fixes Bug 170.	13 years ago

Michael Niedermayer	91ab557b68	Revert "aacdec: Avoid unneeded reinit due to ADTS headers" This has been fixed differently and its revert avoids error messages when decoding xx.flv. This also reduces the difference to qatar. This reverts commit `5a2b3f3a52`.

Janne Grunau	fd095539d1	latmdec: fix audio specific config parsing 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.
