Michael Niedermayer	2545182c29	avcodec/mpegaudiodec_template/mp3on4: check that all channels have been decoded before returnig a frame Fixes use of uninitialized memory Fixes: msan_uninit-mem_7f80bf9a259e_5774_id5_1.mp4 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	c925e960e8	mp3on4: fail when the header check fails It seems the code assumed that when one out of multiple blocks fail some span of time is correct, its not, its some channels that are correct Fixes use of uninitialized memory Fixes: msan_uninit-mem_7f44a03ba3ce_5692_id5_1.mp4 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Martin Storsjö	35686a289f	mp3adu: Set the channel layout properly This fixes decoding, broken since `7e35037`. This is similar to what was done for the normal mp3 decoder in `f4a86bc9`. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Michael Niedermayer	babb611d35	libavcodec/mpegaudio: change CONFIG_FLOAT to USE_FLOAT The CONFIG_ name-space is set by configure, so its better to use a different prefix here. This also unifies the encoder & decoder define that is used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 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

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
