Jason Garrett-Glaser	902685b8ab	VP3: fix decoding of videos with stride > 2048 Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale.	14 years ago
Jean-Daniel Dupas	351423ae1f	targa: fix potential buffer overreads Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Young Han Lee	979395bbbb	mdct: remove unnecessary multiplication 3*n4 was already calculated in n3.	14 years ago
Justin Ruggles	5b54d4b376	ac3enc: fix bug in stereo rematrixing decision. The rematrixing strategy reuse flags are not reset between frames, so they need to be initialized for all blocks, not just block 0. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Michael Niedermayer	50a82c2c75	vbv_delay AVOption for ABI compatibility Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Carl Eugen Hoyos	2e3c56a29f	Set maximum lowres value for the MJPEG decoder to 3. While 4 works for some samples, 3 is the correct value since 8x8 DCT is used by (m)jpeg. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Justin Ruggles	1f004fc512	ac3dsp: Change punpckhqdq to movhlps in ac3_max_msb_abs_int16(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Justin Ruggles	50d7140441	ac3enc: change default floor code to 7. This is to match the value in every (E-)AC-3 file from commercial sources. It has a negligible effect on audio quality. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Christophe Massiot	55bad0c602	Pass VBV delay to the calling application via ctx VBV delay is useful for T-STD compliance in some TS muxers. It is certainly possible to retrieve it by parsing the output of FFmpeg, but getting it from the context makes it simpler and less error-prone.

Peter Ross	9806fbd535	binkaudio: fix channel count check Perform validity check on AVFormatContext.channels instead of uninitialised field. This fixes issue 2001. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Justin Ruggles	fbb6b49dab	ac3enc: Add x86-optimized function to speed up log2_tab(). AC3DSPContext.ac3_max_msb_abs_int16() finds the maximum MSB of the absolute value of each element in an array of int16_t. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anatoly Nenashev	7a4abe5912	mpeg4video: ignore broken GOP headers Some MPEG4 cameras produce files with empty GOP headers. This patch makes the decoder ignore such broken headers and proceed with the following I-frame. Without this change, the following start code is missed resulting in the entire I-frame being skipped. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Loren Merritt	e6b1ed693a	FFT: factor a shuffle out of the inner loop and merge it into fft_permute. 6% faster SSE FFT on Conroe, 2.5% on Penryn. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Peter Ross	2315392174	bink: permute Bink version 'b' quant matrices by inverse scan order This fixes visual glitches in Bink version 'b' files, as the quantization tables were not being permuted. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Peter Ross	cb62510cab	bink: simplify how quantization matrices are passed to read_dct_coeffs() Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Vitor Sessak	47d62c965b	Make tables generation insensitive to floating-point implementation Using doubles make the double -> int cast well defined for all the values used, with the exception of when s[i]==1.0, which is special-cased. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Jason Garrett-Glaser	f3d09d44b7	VP8: optimized mv prediction and decoding Merge find_near_mvs and mv bitstream decoding: don't do prediction steps until absolutely necessary.	14 years ago
Justin Ruggles	626264b11b	ac3enc: Remove unneeded clipping of shift amount. s->windowed_samples will always have a range of [-32767,32767] due to the window function, so the return value from log2_tab() will always be in the range [0,14]. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	d4582889ee	ac3enc: remove right shifting from lshift_tab() and make lshift unsigned. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Reimar Döffinger	4a72765a1c	Do not fail DVB sub decoding because of a few padding bytes Instead of returning an error when bytes are left over, just return the number of actually used bytes as other decoders do. Instead add a special case so an error will be returned when none of the data looks valid to avoid making debugging a pain. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago

Mans Rullgard	b4668274b9	Remove incorrect return statement from avcodec_thread_free() The function return type is void, so a return statement with an expression is forbidden (and pointless). Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	9a77a92c2b	Fix build with threading disabled The avcodec_thread_free() compatibility wrapper calls ff_thread_free(), which is not defined when threading is disabled. Make this call conditional. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	aef669cdfd	w32thread: add missing #include thread.h This should fix building with win32 threads. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
