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
Martin Storsjö	774e6fc9ed	libvpxenc: Support forcing keyframes Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Mans Rullgard	ec5da7aee2	ac3dec: decode directly into output buffers Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	30b3916425	ac3dec: make downmix() take array of pointers to channel data	12 years ago
Mans Rullgard	b8f3ab8e6a	ac3dec: output planar float only 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
Mans Rullgard	cd71af90a9	takdec: fix initialisation of LOCAL_ALIGNED array When LOCAL_ALIGNED uses manual alignment initialisation is not possible. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Paul B Mahol	57231e4d5b	tak: demuxer, parser, and decoder Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Michael Niedermayer	096abfa150	parser: fix large overreads Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	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	c29d49c1b3	dct-test: arm: indicate required cpu features for optimised funcs Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	380232fac3	snow: fix build after `594d4d5df3`	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
Christophe Gisquet	2aef3d66c9	SBR DSP x86: implement SSE sbr_hf_gen Start and end index are multiple of 2, therefore guaranteeing aligned access. Also, this allows to generate 4 floats per loop, keeping the alignment all along. Timing: - 32 bits: 326c -> 172c - 64 bits: 323c -> 156c Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Christophe Gisquet	9a16359c38	AAC SBR: use AVFloatDSPContext's vector_fmul Around 5% speedup on the code block using 'vector_fmul_add's. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago

Anton Khirnov	e57c4706e9	lavc: don't reuse audio buffers Any performance gain from this is negligible and not worth the extra code.	12 years ago
Anton Khirnov	ff953fecff	lavc: set frame properties in ff_get_buffer(). There is no point in duplicating this code in every get_buffer() implementation.	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
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Janne Grunau	0b300daad2	h264: error out on unset current_picture_ptr for h->current_slice > 0 Fixes a segfault with fuzzed sample sample_varPAR_s11622_r001-02.avi. CC: libav-stable@libav.org	12 years ago
Christophe Gisquet	e32bea8eb4	aac: avoid a memcpy in sbr_qmf_analysis Swapping buffer indices allows saving one memcpy that accounts for 1% of the runtime, according to oprofile. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
