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
Michael Niedermayer	4e0738cec9	mpegaudiodec/mp3on4: fix buffer size. The larger (and really ugly) size is not needed anymore. Found-by: Justin Ruggles Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	51fcf276f8	mp3on4: fix null pointer dereference Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Michael Niedermayer	0efcf16a3e	replace av_log(0, by av_log(NULL, The first parameter is a pointer and NULL is more correct Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	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
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	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
Michael Niedermayer	ac7d0c79c3	mp3dec: ask for 8khz switch point mp3s Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	94041febc5	mp3dec: Fix possibly exploitable crash I was sadly unable to find a non fuzzed mp3 that uses the feature that contained the bug (and i searched hard ...), thus while this fixes the security issue. It may or may not fix mixed blocks in 8khz mp3s, i cant say due to lack of samples to test. Security issue exists since: `b37d945dd4` Reported-by: Dale Curtis <dalecurtis@google.com> (Probably) Found-by: inferno@chromium.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	76fac07334	mpegaudiodec: replace pow(2.0,...) by exp2() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.	13 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Michael Niedermayer	29d1df66ad	mpegaudiodec: replace assert() by check under #ifdef DEBUG The assert can be false with some invalid inputs, the check is too expensive to always do though for just a warning message. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Nedeljko Babic	6d74e3c6f2	Optimization of MP3 decoders for MIPS MP3 fixed and floating point decoders are optimized for MIPS architecture.

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

Michael Niedermayer	cca9528524	mp3on4: allocate a large enough frame. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	e2094bd03b	mpeghaudiodec: Fix "set but not used" warnings Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Michael Niedermayer	8263212e86	mpegaudiodec: Enable checked bitstream reader. It appears there are corner cases with damaged input that can lead to small overreads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a057ef6923	mpegaudiodec: change granule skip code to avoid false checked bitstream reader errors. Code ported from qatar/master, please see there for per line authorship. Main authors AFAIK are Ronald and Justin. I have no authorship on this. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.
