Martin Storsjö	e9d61de96c	mpegaudiodec: Validate that the number of channels fits at the given offset This is similar to the fix in `35cbc98b`. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	6fee1b90ce	avcodec: Add av_cold attributes to init functions missing them	12 years ago

Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago
Justin Ruggles	2c785e250a	mpegaudio: decode directly to the user-provided AVFrame	12 years ago
Ronald S. Bultje	5959bfaca3	floatdsp: move butterflies_float from dsputil to avfloatdsp. This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Justin Ruggles	3ffed68c2a	mpegaudiodec: use planar sample format for output unless packed is requested	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Luca Barbato	9ab0874ea8	mp3: properly forward mp_decode_frame errors The function can return either a parsing error or a memory management error.	12 years ago
Luca Barbato	0c03cc6838	mp3: exit on parsing error in mp_decode_frame Properly forward mp_decode_layer3 errors, mp_decode_layer1 and mp_decode_layer2 do not return errors. Based on a patch by Michael Niedermayer.	12 years ago
Michael Niedermayer	ec444c84cf	mpegaudiodec: Fix buffer handling on random access	12 years ago
Diego Biurrun	2f17f265ed	mpegaudio: Refactor mp3on4 flush function	12 years ago
Diego Biurrun	1218777ffd	avcodec: Convert some commented-out printf/av_log instances to av_dlog	12 years ago
Diego Biurrun	6f6b0311a3	avcodec: Drop some silly commented-out av_log() invocations	12 years ago
Luca Barbato	97cfa55eea	mpegaudiodec: fix short_start calculation The value should be always 3, as it follows from the specification. Fix a stack buffer overflow in exponents_from_scale_factors as reported by asan. Thanks to Dale Curtis for the sample vector.	12 years ago
Anton Khirnov	927e92cdc7	mpegaudiodec: don't print an error on > 1 frame in a packet. It's a perfectly normal situation, nothing to spam about.	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Kostya Shishkov	b37d945dd4	mp3: fix start band index for block type 2 in 8kHz audio In hybrid frames long window part ends at 36 samples for most of the cases but at 72 for 8kHz case. For some reason decoder assumed it's 48 or even 36 samples, which caused wrong bitstream decoding for such blocks. l3_25207.mpg from conformance suite demonstrates it the best.	13 years ago
Diego Biurrun	aa3f2cb584	mpegaudiodec: Do not discard mp_decode_frame() return value. This fixes the warning: libavcodec/mpegaudiodec.c:1704:14: warning: variable ‘out_size’ set but not used	13 years ago
Kostya Shishkov	a05c41acd1	mp3dec: perform I/S and M/S only when frame mode is joint stereo. Looks like some LAME versions produce dual stereo mode MP3s with flags for intensity and middle stereo set. In this mode those flags should be ignored like the reference decoder and derived ones do.	13 years ago
Diego Biurrun	a92be9b856	Replace memset(0) by zero initializations. Also remove one pointless zero initialization in rangecoder.c.	13 years ago
Anton Khirnov	02beb9826b	lavc: deprecate AVCodecContext.sub_id. In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.	13 years ago
Vitor Sessak	9b4cd58611	mpegaudiodec: use DSPUtil.butterflies_float(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Dale Curtis	b716542691	mpegaudiodec: Prevent premature clipping of mp3 input buffer. Instead of clipping extrasize based on EXTRABYTES, clip based on the amount of buffer actually left. Without this fix, there are warbles and other distortions in the test case below. http://kevincennis.com/mix/assets/sounds/1901_voxfx.mp3	13 years ago
Ronald S. Bultje	3e13005cac	mp3on4: require a minimum framesize. If bufsize < headersize, init_get_bits() will be called with a negative number, causing it to fail and any subsequent call to get_bits() will crash because it reads from a NULL pointer. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Alex Converse	f372ce119b	mp3dec: Fix a heap-buffer-overflow In some cases, what is left to read from ptr is smaller than EXTRABYTES. Based on a patch by Thierry Foucu <tfoucu@gmail.com>. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Anton Khirnov	ac84395d6a	lavc: remove disabled FF_API_PARSE_FRAME cruft.	13 years ago
Dustin Brody	d2a0041c20	mpegaudiodec: switch error detection check to AV_EF_BUFFER Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Vitor Sessak	39df0c434c	mpegaudiodec: optimized iMDCT transform Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Vitor Sessak	6dfcf53092	mpegaudiodec: move imdct and windowing function to mpegaudiodsp Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Vitor Sessak	421c99a4a7	mpegaudiodec: interleave iMDCT buffer to simplify future SIMD implementations Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Vitor Sessak	96219141e2	mpegaudiodec: Use clearer pointer math Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	03fafdec82	mpegaudiodec: skip all channels when skipping granules Also fix calculation of new position when switching buffers. This fixes "overread" error messages when seeking.	13 years ago
Ronald S. Bultje	464f26889c	mpegaudiodec: fix seeking. The safe bitstream reader does not allow using skip_bits_long() to seek to a point before the start of the buffer, which was needed by the mp3 decoder. This change instead calculates the start point of the first valid granule and skips to that position. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	481a7ff5bd	mpegaudiodec: fix compilation when testing the unchecked bitstream reader	13 years ago
Mans Rullgard	ac08f798bb	mp3dec: hack: fix decoding with safe bitstream reader The buffer splicing relies on the bitstream reader over-reading the end of the buffer as declared in init_get_bits(), although more data is actually present. Manually moving the bitstream boundary after init_get_bits() allows this to work as expected. Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	0df5e869cb	mpegaudio: do not use init_static_data() for initializing tables. It is called once for each mpegaudio codec that is registered, which adds significant overhead.	13 years ago
Martin Storsjö	268fb3f985	mpegaudiodec: Don't use a nonexistent log context for av_dlog This fixes builds with DEBUG defined, broken since `1158745a2d`. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	f1d1516e55	cosmetics: indentation	13 years ago
Justin Ruggles	1158745a2d	mpegaudiodec: init static tables in AVCodec.init_static_data()	13 years ago
Justin Ruggles	ec6d743118	mp3on4: do not needlessly set data_size to 0	13 years ago
Justin Ruggles	99975966c3	mp3adu: return error instead of just consuming bad packets	13 years ago
Justin Ruggles	e2e6c8799b	mpegaudiodec: check output data size based on avctx->frame_size	13 years ago
Justin Ruggles	512557b291	avcodec: remove avcodec_parse_frame and deprecate associated elements. The documentation for CODEC_CAP_PARSE_ONLY and AVCodecContext.parse_only indicates that they are utilized through avcodec_parse_frame(), which was never actually implemented.	13 years ago
Justin Ruggles	cd816d9bbb	mpegaudiodec: cosmetics: basic pretty-printing	13 years ago
