Luca Barbato	23bd9ef4b2	vorbisdec: Accept 0 amplitude_bits The specification does not prevent an encoder to write the amplitude 0 as 0 amplitude_bits. Our get_bits() implementation might not support a zero sized read properly, thus the additional branch.	12 years ago
Luca Barbato	5b47c19bfd	vorbisdec: Add missing checks Rate and order must not be 0 even if the specification does not say that explicitly.	12 years ago
Luca Barbato	fc386f2eea	vorbisdec: cosmetics Use the commonly used "if (!var)" instead of "if (var == 0)".	12 years ago
Michael Niedermayer	11dcecfcca	vorbisdec: Error on bark_map_size equal to 0. The value is used to calculate output LSP curve and a division by zero and out of array accesses would occur. CVE-2013-0894 CC: libav-stable@libav.org Reported-by: Dale Curtis <dalecurtis@chromium.org> Found-by: inferno@chromium.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Stefano Sabatini	5085b46496	lavc: change type of AVFrame.channels field from int64_t to int "channels" is an int in all the other places in the libraries, and the av_frame_*_channels() accessors return and set an int, so this should not implicate ABI breaks.	12 years ago
Reimar Döffinger	c65eb7907c	mpeg12: Fix non-hwaccel VDPAU decode. Previously avctx->hwaccel would have been set to a dummy value, now an explicit check is necessary instead. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Diego Biurrun	3d035d5a6a	dsputil_alpha.h: Add missing stddef.h header to fix standalone compilation	12 years ago

Paul B Mahol	645f96f129	exr: check color channel subsampling too If there is unsupported subsampling encountered abort early instead of failing decoding later. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago

Justin Ruggles	d7c450436f	ac3dec: validate channel output mode against channel count Damaged frames can lead to a mismatch, which can cause a segfault due to using an incorrect channel mapping. CC:libav-stable@libav.org	12 years ago
Diego Biurrun	94ee7da08d	Remove pointless av_cold attributes in header files The init functions marked as av_cold have to be executed in any case, so there is no gain from trying to mark paths leading to such functions as unlikely.	12 years ago
Kostya Shishkov	b5f536d24b	pnm: add high-bitdepth PGMYUV support for both encoder and decoder	12 years ago
Michael Niedermayer	c10c2aed47	h264: Silence warning: comparison of distinct pointer types lacks a cast Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

John Van Sickle	2f325a6fd4	libx264: change i_qfactor to use x264cli's default This also allows libx264 to modify its i_qfactor value when using the "-tune" setting. Previously it had a static value of 1.25 Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Malcolm Bechard	239b88c284	Improve QTRLE encoding performance, no change to output file size/content. Avoid searching for the lowest bulk cost for each pixel that isn't a repeat/skip. Instead store the lowest cost as we go along each pixel, and use it as needed.

Paul B Mahol	1178868683	exr: fix overflow check in lineoffset processing Also read data size for raw compressions too and make sure its value is sane.
