Michael Niedermayer	c9aab8a123	h264: use mbaff ref indices in fill_colmap() only for mbaff references Prevents writing beyond array bounds. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago
Janne Grunau	61c6eef545	h264: prevent decoding of slice NALs in extradata It is not posible to call get_buffer during frame-mt codec initialization. Libavformat might pass huge amounts of data as extradata after parsing broken files. The 'extradata' for the fuzzed sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains multiple slices.	12 years ago
Diego Biurrun	81c7c817a4	cosmetics: Use consistent names for multiple inclusion guards.	12 years ago
Janne Grunau	a421bbfe83	h264: fix memleak on error during SPS parsing Introduced in `d7d6efe42b`.	12 years ago
Janne Grunau	27c8337e59	h264-mt: handle NAL_DPAs before calling ff_thread_finish_setup Since a NAL_DPA can start a new frame it has to be handled before ff_thread_finish_setup is called.	12 years ago
Luca Barbato	f33b5ba63e	vp56: release frames on error Fixes CVE-2012-2783 CC: libav-stable@libav.org	12 years ago
Luca Barbato	bb675d3ac6	vp56: make parse_header return standard error codes Returning 0 for failure is misleading. CC: libav-stable@libav.org	12 years ago
Anton Khirnov	deabb52ab4	ivi_common: check that scan pattern is set before using it. Fixes CVE-2012-2791. CC: libav-stable@libav.org	12 years ago
Anton Khirnov	07acdd651d	ivi_common: use proper logging context in ivi_decode_blocks().	12 years ago
Anton Khirnov	8ab42021f2	ivi_common: make some functions and tables static.	12 years ago
Janne Grunau	0eae920c3c	h264: initialize frame-mt context copies properly	12 years ago
Janne Grunau	6a27ae28f9	mpegvideo: treat delayed pictures as used This requires to move the avcodec_default_free_buffers() call to ff_MPV_common_end() since otherwise delayed pictures would get freed during a size change.	12 years ago
Janne Grunau	bd255f9feb	lavc: set frame parameters after decoding only if necessary Direct rendering capable decoders call get_buffer() which will set the frame parameters. Prevents frames with wrong parameters when a decoder outputs delayed frames after a resolution or pixel format change.	12 years ago
Janne Grunau	072be3e896	h264: set parameters from SPS whenever it changes Fixes a crash in the fuzzed sample sample_varPAR.avi_s26638 with alternating bit depths.	12 years ago
Luca Barbato	be75fed975	vp6: properly fail on unsupported feature Interlacing is not supported at all and mismanaged down the normal codepaths causing possible buffer management issues. CC: libav-stable@libav.org	12 years ago
Alex Converse	6d5b009267	aacdec: Fix an off-by-one overwrite when switching to LTP profile from MAIN. Found-by: pawlkt CC: libav-stable@libav.org	12 years ago

Anton Khirnov	c4182d72c9	svq1: return meaningful error codes.	12 years ago
Anton Khirnov	998fdcff41	lavc: replace some forgotten instances of PixelFormat with AVPixelFormat	12 years ago
Anton Khirnov	84a0806680	svq1: unmacroify macros used only once.	12 years ago
Anton Khirnov	95baf701db	svq1: deMpegEncContextize This decoder is quite simple and none of the MpegEncContext complexity is actually needed.	12 years ago
Ronald S. Bultje	6f40e9f070	x86inc: support stack mem allocation and re-alignment in PROLOGUE Use this in VP8/H264-8bit loopfilter functions so they can be used if there is no aligned stack (e.g. MSVC 32bit or ICC 10.x). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Mans Rullgard	02823f6d71	Make LOCAL_ALIGNED syntactically similar on all systems This changes the LOCAL_ALIGNED definition on systems where DECLARE_ALIGNED is used so it matches the manual alignment case, ensuring invalid use will not compile on x86 only to fail on everything else. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Carl Eugen Hoyos	2ddf7c88d1	ZeroCodec: Flip output The initial testing of the VFW binary codec was flawed, likely due to an AviSynth bug. Re-testing using VirtualDub and various professional editing applications has revealed it should have been flipped. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mans Rullgard	f9e493c6f5	sh4: dsputil: remove duplicate of ff_gmc_c() This function is an exact duplicate of the generic one. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	2dd95bd7cf	dsputil: remove unused macro WRAPPER8_16 This macro has never been used. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Janne Grunau	288bb3da16	svq3: make slice type value unsigned to match svq3_get_ue_golomb return type	12 years ago
Diego Biurrun	ba0c898120	cosmetics: Fix dropable --> droppable typo	12 years ago
Janne Grunau	6a1aa5cb26	mjpeg: initialize input padding after unescaped buffer to zero Fixes valgrind --undef-value-errors=yes warnings caused by valid overreads in the fate vsynth jpegls, cover-art-ape and cover-art-wv tests.	12 years ago
Ronald S. Bultje	ddd7559ad9	h264: check for invalid zeros_left before writing Prevent an invalid write into coeffs[scantable[-1]] if zeros_left itself was an invalid VLC code (and thus -1). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Janne Grunau	9a2e79116d	golomb: use unsigned arithmetics in svq3_get_ue_golomb() This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.	12 years ago
Josh Allmann	b3deec3253	takdec: fix initialisation of LOCAL_ALIGNED array When LOCAL_ALIGNED uses manual alignment initialisation is not possible. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago

Michael Niedermayer	41540b36a1	bitstream: add get_bits64() to support reading more than 32 bits at once Also remove a duplicate function in the MPEG-TS demuxer. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Mans Rullgard	b326755989	arm: rename ARMVFP config symbol to VFP This is consistent with usual ARM nomenclature as well as with the VFPV3 and NEON symbols which both lack the ARM prefix. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	a7831d509f	arm: use HAVE*_INLINE/EXTERNAL macros for conditional compilation These macros reflect the actual capabilities required here. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	92dad6687f	arm: fix use of uninitialised value in ff_fft_fixed_init_arm() When initialising an FFTContext for a plain FFT, mdct_bits is not set and can contain a garbage value. Since nbits is always valid and for MDCT operation is mdct_bits - 2 checking this instead avoids using an uninitialised value while having the same effect. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Martin Storsjö	2c96392277	avpicture: Don't assume a valid pix fmt in avpicture_get_size When called from the v4l2 input device, pix_fmt can be AV_PIX_FMT_NONE (for jpeg formats). Before `50ba57e0`, this wasn't an issue for avpicture_get_size, but after that commit, this lead to crashes. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Janne Grunau	a394959bbe	h264: add a pointer for weighted prediction temporary buffer Reusing MpegEncContext's obmc_scratchpad for this becomes a mess with adaptive frame-mt.	12 years ago
Janne Grunau	d7d6efe42b	h264: check sps.log2_max_frame_num for validity Fixes infinite or long taking loop in frame num gap code in the fuzzed sample bipbop234.ts_s223302. CC: libav-stable@libav.org	12 years ago
Janne Grunau	480be07a96	flac: change minimum and default of lpc_passes option to 1 Avoid use of uninitialized and uncomputed linear least square models during ff_lpc_calc_coefs() for FF_LPC_TYPE_CHOLESKY. Fixes running make fate-flac-16-lpc-cholesk with valgrind --undef-value-errors=yes.	12 years ago
