Anton Khirnov	221402c1c8	pcx: check that the packet is large enough before reading the header Fixes possible invalid reads. CC: libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	8 years ago
Anton Khirnov	15ee419b7a	pcx: properly pad the scanline It is passed to the get_bits API, which requires buffers to be padded. Fixes possible invalid reads. CC: libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	8 years ago
Anton Khirnov	409d1cd2c9	cook: use the bytestream2 API for reading extradata Fixes possible invalid reads in corrupted files. CC: libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	8 years ago
Anton Khirnov	bba9d8bdfb	qpeg: fix an off by 1 error in the MV check height - me_y is the line from which we read, so it must be strictly smaller than the frame height. Fixes possible invalid reads in corrupted files. Also, use a proper context for logging the error. CC: libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	8 years ago
Anton Khirnov	796dca027b	alac: do not return success if nothing was decoded If we encounter an END element before anything is decoded, we would return success even though the output frame has not been allocated, which is invalid.

Anton Khirnov	f5d46d3322	vmnc: check that subrectangles fit into their containing rectangles Fixes possible invalid writes with corrupted files. CC: libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	8 years ago

Ronald S. Bultje	1730a67ab9	vp9: add frame threading Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Ronald S. Bultje	5b995452a6	vp9: allocate 'b', 'block/uvblock' and 'eob/uveob' dynamically. This will be needed for frame threading. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Ronald S. Bultje	bc6e0b64a9	vp9: split last/cur_frame from the reference buffers. We need more information from last/cur_frame than from reference buffers, so we can use a simplified structure for reference buffers, and then store mvs and segmentation map information in last/cur. This prepares the decoder for frame threading support. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Anton Khirnov	04763c6f87	h264_direct: use the reference mask from the actual reference Not from the underlying frame. Fixes races with frame threading in field-coded files, where decoding would wait for the wrong field (e.g. random failures in mixed-nal-coding). Bug-Id: 954	8 years ago
Anton Khirnov	e9bfff1cc6	lavc: free buffer_frame/pkt on avcodec_open2() failure Fixes memory leaks in some FATE tests.	8 years ago
Ronald S. Bultje	0df4801105	vp9: make mv bounds 32bit. The frame dimensions are 16bit, so the mv bounds can easily overflow int16 for large videos. Bug-Id: Handbrake/46 CC: libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Ronald S. Bultje	9790b44a89	vp9mc/x86: sse2 MC assembly. Also a slight change to the ssse3 code, which prevents a theoretical overflow in the sharp filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
James Almer	67922b4ee4	vp9mc/x86: add AVX and AVX2 MC Roughly 25% faster MC than ssse3 for blocksizes 32 and 64. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago

James Almer	8be8444d01	vp9mc/x86: rename ff_avg[48]_sse to ff_avg[48]_mmxext pavgb is an sse integer instruction, so the mmxext flag is enough Signed-off-by: James Almer <jamrial@gmail.com> Reviewed-by: "Ronald S. Bultje" <rsbultje@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago

Martin Storsjö	9806b9ab5c	Revert "Don't use expressions with side effects in macro parameters" This reverts commit `25bacd0a0c`. Since `230b1c070`, the bytewise AV_W*() macros only expand their argument once, so revert to the more readable version of these. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	25bacd0a0c	Don't use expressions with side effects in macro parameters AV_WB32 can be implemented as a macro that expands its parameters multiple times (in case AV_HAVE_FAST_UNALIGNED isn't set and the compiler doesn't support GCC attributes); make sure not to read multiple times from the source in this case.
