Anton Khirnov	7fb6c9225c	lavc: free the output packet when encoding failed or produced no output.	13 years ago
Anton Khirnov	e42e9b0e4d	lavc: preserve avpkt->destruct in ff_alloc_packet(). Also, don't bother with saving/restoring data, av_init_packet doesn't touch it.	13 years ago
Anton Khirnov	c179c9e19d	lavc: clarify the meaning of AVCodecContext.frame_number.	13 years ago
Michael Niedermayer	c266eb1928	arm: Fix 10l typo Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	70b5583baa	kvmc: Fix out of reference frame reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	81d4b3af81	qpeg: fix overreads. qpeg should probably be changed to use the checked bytestream reader. But for now this fixes it and is significantly less work.

Ronald S. Bultje	9d87374ec0	amrwb: remove duplicate arguments from extrapolate_isf(). Prevents warnings because the dst and src overlap (are the same) in the memcpy() inside the function. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Michael Niedermayer	e7b43e8e84	truemotion1: Check input buffer size against header size. Fixes overread. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Ronald S. Bultje	154b8bb800	amrwb: error out early if mode is invalid. Prevents using the invalid mode as an index in a static array, which would generate invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	291c9b6285	h264: change underread for 10bit QPEL to overread. This prevents us from reading before the start of the buffer, and thus prevents crashes resulting from this behaviour. Fixes bug 237.	13 years ago
Ronald S. Bultje	45549339bc	vp8: disable mmx functions with sse/sse2 counterparts on x86-64. x86-64 is guaranteed to have at least SSE2, therefore the MMX/MMX2 functions will never be used in practice.	13 years ago
Ronald S. Bultje	bd66f073fe	vp8: change int stride to ptrdiff_t stride. On 64bit platforms with 32bit int, this means we won't have to sign- extend the integer anymore.	13 years ago
Ronald S. Bultje	349b7977e4	wma: fix invalid buffer size assumptions causing random overreads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Martin Storsjö	b087ce2bee	g722: Fix the QMF scaling This fixes clipping if the encoder input used the full 16 bit input range (samples with a magnitude below 16383 worked fine). The filtered subband samples should be 15 bit maximum, while the code earlier produced them scaled to 16 bit. This makes the decoder output have double the magnitude compared to before. The spec reference samples doesn't test the QMF at all, which was why this part slipped past initially. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
