Anton Khirnov	1f097d168d	h264: reset data partitioning at the beginning of each decode call Prevents using GetBitContexts with data from previous calls. Fixes access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	e46ad30a80	vp8: use a fixed-size edge emu buffer The reason is the same as for `e588615d93` Based on a patch by Ronald S. Bultje <rsbultje@gmail.com>	11 years ago

Jan Ekström	5de64bb34d	utvideoenc: Add support for the new BT.709 FourCCs for YCbCr With cli usage the decoder might have not set the colorspace during encoder init, manual colorspace override might be needed in such cases. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Keith Lawson	de203abd71	vf_overlay: add eof_action switch Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Luca Barbato	816e5b9970	hevc: Reject impossible slice segment A dependent slice cannot have address 0. Prevent an out of array bound load in ff_hevc_cabac_init(). Sample-Id: 00001406-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
Luca Barbato	09e2203b8b	hevc: Consider first quantization group any reference to 0, 0 According to my understanding of T-REC-H.265-2013044 chapter 8.6.1. Sample-Id: 00001438-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago

Janne Grunau	7716dd9fbb	xvid: switch to xvid mmx idct as soon as possible The idct implementation cannot be changed after the quantization matrices are read since it use a different permutaion. Bug-Id: videolan/7411	11 years ago
Janne Grunau	78987a88a8	lavf: include 60 fps in guessed standard frame rates Due to what looks like an off-by-one error 60 * 12 * 1001 / 12 * 1001 is not tested as standard frame rate in avformat_find_stream_info().	11 years ago
Jan Ekström	5312818524	atrac3plus: Make initialization dependant on channel count rather than channel map Makes it easier to recreate an AVCodecContext for ATRAC3+ decoding, which is needed in multimedia frameworks, as well as in general cases where demuxing and decoding are separate entities.	11 years ago
Ronald S. Bultje	9ee9c679a7	x86: videodsp: Fix a bug in a %if statement where we used '%%' instead of '&&'. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Ronald S. Bultje	51daafb02e	x86: videodsp: Properly mark sse2 instructions in emulated_edge_mc as such. Should fix crashes or corrupt output on pre-SSE2 CPUs when they were using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in hfix or hvar single-edge (left/right) extension functions.

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	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

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
