Kostya Shishkov	15358ade15	mss1: validate number of changeable palette entries	13 years ago
Kostya Shishkov	8f5d573a83	mss1: report palette changed when some additional colours were decoded	13 years ago
Christophe Gisquet	a5bfa66df5	x86: fft: replace call to memcpy by a loop The function call was a mess to handle, and memcpy cannot make the assumptions we do in the new code. Tested on an IMC sample: 430c -> 370c. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	fa84506177	dxva2: include dxva.h if found Apparently, some build environments require dxva.h even for dxva2, while others lack this header entirely. Including it conditionally allows building in both cases. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Hendrik Leppkes	ea1c5011b3	dxva2_h264: fix signaling of mbaff frames The MBAFF flag may only be signaled if we're actually dealing with a full frame, and not singular fields, as it can happen in mixed content. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	0595334892	x86: fft: elf64: fix PIC build In a 64-bit PIC build, external functions must be called through the PLT. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Ronald S. Bultje	8123e0901f	x86: place some inline asm under #if HAVE_INLINE_ASM Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	0b6f973635	h264: use asm cabac reader under a generic condition This removes a dependency on implementation details from generic code and allows easy addition of the equivalent optimisation for other architectures than x86. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	fe07c9c6b5	x86: Only use optimizations with cmov if the CPU supports the instruction	13 years ago

Janne Grunau	1d01fee980	fix hardcoded tables compililation caused by missing math constants Add -D_XOPEN_SOURCE=600 to host cflags to make the constants in math.h available. Include math.h where necessary and remove redundant M_PI defines.	13 years ago
Ronald S. Bultje	89ffd189ef	twinvq: give massive struct a name. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	a50b756280	lavc: remove stats_in from AVCodecContext options table. Its documentation states that it is allocated/freed by the caller, but it is declared as an AV_OPT_TYPE_STRING AVOption. Since `367732832f` the AVOptions system frees strings automatically. This can be considered an API break, since it won't work when the caller doesn't use av_malloc() to allocate the memory or wants to use the string after closing the codec. Since there is not much value in this field being an AVOption, the best solution is to remove it from the options table.	13 years ago
Kostya Shishkov	005c80b645	MS Screen 1 decoder	13 years ago
Alex Converse	43886eaebc	aacdec: Fix popping channel layouts. 'channel_layout' not 'channels' from the stored configuration should go to AVCodecContext's 'channel_layout'.	13 years ago
Mans Rullgard	980f81d961	Use av_gettime() in various places Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	db7d8fb4ef	dct-test: use emms_c() from libavutil instead of duplicating it	13 years ago
Diego Biurrun	4cc2920dd2	flvdec: remove incomplete, disabled seeking code	13 years ago
Simon A. Eugster	7146177d18	lavc: Extend the documentation for avcodec_init_packet Add a note that pkt->data and pkt->size must be initialized. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	cb5042d02c	float_dsp: Move vector_fmac_scalar() from libavcodec to libavutil	13 years ago
Martin Storsjö	3641b0489c	Add support for iLBC decoding/encoding via the external library libilbc The library is 3-clause BSD licensed. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Diego Biurrun	d246c18ea6	Avoid C99 variable declarations within for statements. We generally do not declare variables within for statements and there are compilers that choke on such constructs.	13 years ago
Diego Biurrun	af10feadc2	ppc: Rename H.264 optimization template file for consistency.	13 years ago
Justin Ruggles	4795362660	golomb: check remaining bits during unary decoding in get_ur_golomb_jpegls() Fixes infinite loop in FLAC decoding in case of a truncated bitstream due to the safe bitstream reader returning 0's at the end. Fixes Bug 310. CC:libav-stable@libav.org	13 years ago
Michael Niedermayer	bcbb30e2a0	libmp3lame: add missing layout terminator Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Mans Rullgard	30f515091c	h264: allow cropping to AVCodecContext.width/height Override the frame size from the SPS with AVCodecContext values if the latter specify a size smaller by less than one macroblock. This is required for correct cropping of MOV files from Canon cameras. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kostya Shishkov	cac4760bf4	iac: generate codec tables as they are supposed to be Unlike its predecessor, Indeo Audio codec generates tables depending on sampling rate. Previously decoder used pre-generated tables for 22050 Hz which obviously doesn't work with other frequencies. Many thanks to Maxim Poliakovsky for providing all needed information for this.	13 years ago
Kostya Shishkov	e1a3fa5d3a	indeo4: handle frame type 1 properly It turns out that this frame type is actually intra and should be used as a reference for interframes too.	13 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Justin Ruggles	98db4e2a4e	PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil This will allow for easier implementation of Altivec functions in libraries other than libavcodec.	13 years ago
Justin Ruggles	94d2b0d2fd	ARM: Move asm.S from libavcodec to libavutil This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec.	13 years ago
Mans Rullgard	bc92214e27	vc1dsp: mark put/avg_vc1_mspel_mc() always_inline This ensures that these functions are inlined into the per-position entry points, allowing constant propagation as needed for proper optimisation. 18% faster VC1 decoding on Cortex-A9. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Alex Converse	ecf79c4d3e	vorbis: Validate that the floor 1 X values contain no duplicates. Duplicate values in this vector are explicitly banned by the Vorbis I spec and cause divide-by-zero crashes later on.	13 years ago

Kostya Shishkov	34271cabac	imc: make IMDCT support stereo output This will be useful for Indeo Audio decoder which is almost the same but supports stereo.	13 years ago
Kostya Shishkov	c45e2da617	imc: move channel-specific data into separate context This will be useful for Indeo Audio decoder which is almost the same but supports stereo.	13 years ago
Kostya Shishkov	b56825c40e	mpc8: fix maximum bands handling In Musepack SV8 codec property tell the maximum nonzero band, but every frame codes maximum band as a limit (i.e. strictly less than given value). Synthesis also expects maximum nonzero band, so there's a need to convert frame maximum band limit value.	13 years ago
Alex Converse	79c8e29a7e	aacdec: Turn PS off when switching to stereo and turn it to implicit when switching to mono.	13 years ago
Kostya Shishkov	96fadfb158	bmv: add stricter checks for invalid decoded length This makes decoder handle random data passed as BMV frame data.	13 years ago
Anton Khirnov	cf3a1948e9	avpacket: fix duplicating side data. Use correct side data size instead of just zeroed field.	13 years ago
