Loren Merritt	b7d0d10a1d	x86inc: Speed up assembling with Yasm Work around Yasm's inefficiency with handling large numbers of variables in the global scope. Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Diego Biurrun	50ecf15712	avformat: utils: K&R formatting cosmetics Also adjust some comment wording / spelling and reorder header #includes.	11 years ago
Janne Grunau	9e057f53aa	configure: clang: explicitly state dep file and rule name in DEPFLAGS Fixes dependency file generation with gas-preprocessor.pl and clang. Flags copied from GCC and tested with Apple's clang from Xcode 5 and 5.1 and clang 3.2, 3.3, 3.4 on Linux.	11 years ago
Janne Grunau	fb87e69ff7	configure: add missing x86 dependency for i686	11 years ago
Janne Grunau	6d93307f8d	mpeg12: check scantable indices in all decode_block functions Add checks to the fast functions used with CODEC_FLAGS2_FAST and move the check for all other functions to before the invalid memory is accessed. Fixes https://trac.videolan.org/vlc/ticket/9713 with CODEC_FLAGS2_FAST. CC: libav-stable@libav.org	11 years ago
Janne Grunau	fb0c9d41d6	avutil: remove timer.h include from internal.h Added libavutil/timer.h include to all files with {START,STOP}_TIMER.	11 years ago
Kostya Shishkov	28e1eed3c2	dxtory: compressed RGB555/RGB565 decoding support	11 years ago
Kostya Shishkov	0e1ad2f591	dxtory: add more compressed and uncompressed modes	11 years ago
Guillaume Martres	50866c8d95	vp9: fix bugs in updating coef probabilities with parallelmode=1 - The memcpy was completely wrong because s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas s->prob.coef is a [4][2][2][6][6][11] array. - The additional check was committed to ffmpeg by Ronald S. Bultje. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Ronald S. Bultje	bd01412313	vp9: fix mvref finding to adhere to bug in libvpx. Fixes a particular youtube video that I unfortunately can't share. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Martin Storsjö	2aec9e228c	rtpdec_asf: Copy the need_parsing field from the chained demuxer This fixes playback of mp3 streams in rtp/asf. This used to work until `c6f1dc8`, but mostly by coincidence. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	cff480e49d	mpegvideo_enc: Don't call ff_h263dsp_init unconditionally This fixes builds with e.g. --disable-decoders --disable-encoders --enable-encoder=mjpeg. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	19987fa18c	bfin: vp3: Mark all binary object sections appropriately This fixes a leftover from `e44d7c659b`.	11 years ago
Janne Grunau	ea49f60523	h264: skip chroma edges at the picture boundary while deblocking 4:4:4 This handles macroblock edges for the chroma components in the same way as for the luma compoment for 4:4:4 streams. The Spec explicitly states that the deblocking filter is not applied to edges at the boundary of the picture. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Diego Biurrun	8267f93635	configure: Set default HOSTCFLAGS/HOSTCPPFLAGS after compiler detection This prevents the default HOSTCFLAGS from getting clobbered by flags passed to configure on the command line.	11 years ago
Michael Niedermayer	91c981857b	rgb2rgb_template: add MMX/SSE2/AVX-optimized deinterleaveBytes Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Michael Niedermayer	7597e6efe4	swscale/x86/rgb2rgb: add support for AVX This does not yet include any actual AVX code Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Michael Niedermayer	9047491f8b	swscale: add nv12/nv21->yuv420 converter Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Michael Niedermayer	eb01a25fe1	swscale: fix stride used in planarToNv12Wrapper() Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	e0ab5078a7	lavc: do not force the emu edge flag The default get_buffer2() implementation (and possibly some user ones) does not allocate edges when this flag is set, which may expose bugs in some decoders. Until the 10 release is out, it is safer to remove this part.	11 years ago
Kostya Shishkov	025fd76e1a	dxtory: change error code for unexpected slice configuration	11 years ago
Kostya Shishkov	e91a3f1bdb	dxtory: correctly handle YUV slices with average odd height	11 years ago

Sam Lantinga	5b2b23f2d6	dxva2: Retry IDirectXVideoDecoder_BeginFrame() If the function returns E_PENDING retry for a fixed number of times. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Luca Barbato	e22ebd04bc	hevc: Bound check cu_qp_delta The T-REC-H.265-2013044 page 91 states it has to be in the range [-(26 + s->sps->qp_bd_offset / 2), (25 + s->sps->qp_bd_offset / 2)].	11 years ago
Luca Barbato	0d999333f9	hevc: Bound check slice_qp The T-REC-H.265-2013044 page 79 states it has to be in the range [-s->sps->qp_bd_offset, 51]. Sample-Id: 00001386-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
Luca Barbato	838740e642	hevc: Prevent some integer overflows get_ue_golomb_long() returns an unsigned. Sample-Id: 00001541-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
Guillaume Martres	faf03ecba0	hevc: Remove useless clip The src buffer should only contain values in the interval [0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in the interval [0, 31], so no clip is needed. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Guillaume Martres	a246d06fe0	hevc: clip pixels when transquant bypass is used The reconstructed picture should always be clipped (see section 8.6.5), previously we did not clip coding units where cu_transquant_bypass_flag == 1. Sample-Id: 00001325-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Luca Barbato	b37e796082	hevc: Use uint64 to check for tile dimensions And use unsigned datatypes. Otherwise it would overflow. Sample-Id: 00001315-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
Michael Niedermayer	d5c15ebeaf	hevc: Fix modulo operations Keep qp fields within the range. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Michael Niedermayer	a7a07cc98a	hevc: check that VPS referenced from SPS exists This matches how its done for SPS/PPS. Fixes null pointer dereference. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Michael Niedermayer	dd2d0039b6	vc1: Always reset numref when parsing a new frame header. Fixes an issue where the B-frame coding mode switches from interlaced fields to interlaced frames, causing incorrect decisions in the motion compensation code and resulting in visual artifacts. CC: libav-stable@libav.org Signed-off-by: Tim Walker <tdskywalker@gmail.com>	11 years ago
Martin Storsjö	89564be444	rtmpproto: Send a full, absolute timestamp if it isn't monotonically growing The normal differential timestamps can't handle negative differences, thus send a full packet header with an absolute timestamp in these cases. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	24eb3c7916	rtmpproto: Avoid using uninitialized memory If the url ends with .flv, we stripped it but didn't initialize rt->playpath, doing av_strlcat on an uninitialized buffer. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Justin Ruggles	d01e684186	mov: do not set avg_frame_rate in the demuxer The track duration is often not reliable or is not the duration represented by the number of frames. In those cases, avg_frame_rate was reported incorrectly. Removing this code falls back to the default calculation in avformat_find_stream_info(). This is a partial revert of commit `c3aeaa540`. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Anton Khirnov	93c553c71e	lavc: deprecate CODEC_FLAG_EMU_EDGE and avcodec_get_edge_width().	11 years ago
Anton Khirnov	024db24912	mpegvideo: allocate edges when encoding. Allocating edges will be removed from generic code, so the encoder must handle this explicitly.	11 years ago
Anton Khirnov	f7e85ee996	lavc: allow the caller to override dimensions in ff_get_buffer() This will be useful for allocating edges in the encoders.	11 years ago
Tim Walker	0d43b114cc	eac3: cosmetics, re-indent.	11 years ago
Tim Walker	ade75fb811	(e)ac3: clip surround mix level indexes. Values 0-2 are reserved, 3 (-1.5dB) should be used instead.	11 years ago
Tim Walker	c229f571fd	(e)ac3: parse and store the Lt/Rt and LFE mix levels.	11 years ago
Tim Walker	1f604f96ea	ac3: set default matrix encoding modes in parse_frame_header. Deduplicates some code.	11 years ago
