Hendrik Leppkes	d039b6074c	latm: fix initialization on some streams when no extradata is available Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	3c928477d2	aacdec: remove dead assignment Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Lou Logan	6851130fd6	cosmetics: minor libavcodec spelling errors Also update some common misspelled words in patcheck Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Hendrik Leppkes	f77fd34bc3	aac: move sample_fmt selection before decoder configuration. The decoder configuration initializes the sbr mdct, which needs to know about the sample format to properly take the scale factor into account. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	43886eaebc	aacdec: Fix popping channel layouts. 'channel_layout' not 'channels' from the stored configuration should go to AVCodecContext's 'channel_layout'.	13 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Alex Converse	79c8e29a7e	aacdec: Turn PS off when switching to stereo and turn it to implicit when switching to mono.	13 years ago
Michael Niedermayer	a48b890392	aacdec: fix "may be used uninitialized" warning Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	faa2930f19	flvdec: reenable extradata passing code This fixes passing junk in stream. It should not have any user vissible effect. We are discarding the new data in the decoder as no case is known where it is needed but it causes problems if used. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a6f650af8d	aac: fix SCE in stereo case, this is surprisingly actually needed Fixes Ticket513 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a3710f1ebb	aacdec: print debug note when unexpected SCE/CPE is encountered Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ole Dittmann	fff9680d8c	aacdec: Add forgotten flush See Ticket420 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	7eacd70fea	aac: Handle HE-AACv2 when sniffing a channel order.	13 years ago
Michael Niedermayer	124eb7e476	aacdec: drop channel reseting code. its no longer needed and causes a race with the flv demuxer. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	aa0f84df5a	aacdec: disable new chan_config guessing code from libav. It causes more problems than it solves. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	dbe29db8cb	aacdec: more verbose overread error message Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	68526dbc29	aacdec: reduce difference to alexs version of aacdec.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	9fb7e14635	aacdec: More robust output configuration. Save the old output configuration (if it has been used successfully) when trying a new configuration. If the new configuration fails to decode, restore the last successful configuration.	13 years ago
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	ba02069a8e	aacdec: prevent channels from exceeding MAX_CHANNELS. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	5a4af049b1	aacdec: reset max_sfb on invalid data. Fixes global out of array read. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	f36d5c1422	Update Janne's email address.	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. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Alex Converse	2564f6e6d4	aacdec: Reshuffle functions so get_che() can call set_default_channel_config() and output_configure().	13 years ago
Diego Biurrun	cfac648e6a	doxygen: Remove documentation for non-existing parameters; misc small fixes.	13 years ago
Alex Converse	5e239c7f9e	aacdec: Remove erroneous reference to global gain from the out of bounds scalefactor error message.	13 years ago
Alex Converse	1cd9a6154b	aac: fix infinite loop on end-of-frame with sequence of 1-bits. Based-on-work-by: Ronald S. Bultje <rsbultje@gmail.com> Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Alex Converse	f1ecd0802d	aacdec: Support native channel layout when requested.	13 years ago
Alex Converse	37bed6ff3f	aacdec: Try to sniff a reasonable channel layout for PCE based configurations. This changes the output order of multichannel PCE based streams.	13 years ago
Alex Converse	8ece266213	aacdec: Remove incorrect comment. It was only correct when element ids met very specific criteria.	13 years ago
Alex Converse	e600a1e44a	aacdec: Simplify output configuration.	13 years ago
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
Alex Converse	4acd43a295	aacdec: Turn off PS for multichannel files that use PCE based configs. Fixes al_sbr_cm_48_5.1.mp4.	13 years ago
Michael Niedermayer	810a14dbcc	aacdec: Evaluate further PCE elements. Fixes Music\ Station\ Super\ Live\ -\ 2011.12.23.mkv Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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`. Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Reimar Döffinger	36be045ed7	Support "VLB " audio in NSV files. See samples/nsv/vlb_audio. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Janne Grunau	d268b79e34	aac_latm: reconfigure decoder on audio specific config changes	13 years ago
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. Data after the audio specific config can be misinterpreted as sync extension resulting in random and wrong configs.	13 years ago
