Michael Niedermayer	c00686518c	avcodec/h263dec: fix handling of AV_EF_EXPLODE This fixes checking a variable that had been overwritten before. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	6c82c87dbb	ac3dec: fix outptr increment. Fixes corrupt data errors when downmixing in the AC-3 decoder. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com> CC:libav-stable@libav.org	12 years ago

Anton Khirnov	a1c5cc429d	lavc: don't set AVFrame.pts to random numbers in decoders.	12 years ago
Martin Storsjö	f2521563d1	g722dec: Change bits_per_codeword to the right option type This isn't a set of flags but just a plain integer in the range 6-8. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	97de206b44	lavc: disable CRC checking by default	12 years ago
Anton Khirnov	23a211cbba	lavc: change all decoders to behave consistently with AV_EF_CRCCHECK. Just crccheck prints a warning, crccheck+explode returns an error. Also document this behavior.	12 years ago
Anton Khirnov	f354f30836	error resilience: check error_concealment, not err_recognition. err_recognition is supposed to trigger detecting and reporting errors, not trying to fix them.	12 years ago
Michael Niedermayer	aaaf2dc023	h263: Check init_get_bits return value And use init_get_bits8 to check for integer overflows while at it. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Luca Barbato	0749314886	h263: Return meaningful errors	12 years ago

Marton Balint	dbe6f9f2c2	lavc: add support for CODEC_CAP_DELAY in subtitles This patch adds CODEC_CAP_DELAY support to avcodec_decode_subtitle2. For DVB teletext decoding, a single teletext packet can contain multiple teletext pages. In order to support that, the teletext decoder may buffer some pages.

Michael Niedermayer	758b6d39f6	avcodec/hevc: calculate checksum only if AV_EF_EXPLODE is set This avoids a slowdown with the default of enabled CRC checks Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	69d39cb90c	Revert "avcodec/options_table: disable CRC checking by default" This reverts commit `c7027ce9ea`. It appears there is no complete consensus on this currently.	12 years ago
Michael Niedermayer	e797bd9dc7	Revert "avcodec/options_table: set err_detect to careful by default" This reverts commit `b1348eb68b`.	12 years ago
Anton Khirnov	94603feb1b	h264_ps: when parsing a VUI fails, only abort when explode is set A VUI doesn't contain anything strictly necessary for decoding. Apparently there are many samples with truncated VUIs in the wild, this commit should allow decoding them.	12 years ago
Vittorio Giovara	fc06ee6ee3	mmvideo: fix uninitialized variable use in mm_decode_intra Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Michael Niedermayer	fc7be7ddf3	avcodec/avcodec.h: Add documentation for the AV_EF_* defifines The documentation is copied from the AVOption texts Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	2ef1e62c8d	correct the AVOption documentation for AV_EF_CAREFUL The flag was and is intended to be a sane default and thus does not enable time consuming checks. This also matches how the flag is used in decoders and demuxers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	efc5a54cab	vp9: skip itxfm_add if the whole block has no coefficients. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	960490c0b2	avcodec/x86/videodsp: Small speedups in ff_emulated_edge_mc x86 SIMD. Don't use word-size multiplications if size == 2, and if we're using SIMD instructions (size >= 8), complete leftover 4byte sets using movd, not mov. Both of these changes lead to minor speedups. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	cd86eb265f	avcodec/x86/videodsp: fix a bug in a %if statement where we used '%%' instead of '&&'. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Yusuke Nakamura	f7f8801839	hevc: Search start code in decode_nal_units(). User may cut off a weird position and send a packet from there. This avoids returning as invalid data immediately.	12 years ago

Michael Niedermayer	41efb8d9a7	avcodec/x86/cabac: include get_cabac_bypass_sign_x86() under #if !BROKEN_COMPILER this might fix Ticket2999 as well as some fate clients untested as the original patch submitter no longer has the environment to test this should be reverted if it does not fix the issues Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	08a8976196	avcodec/h264: reduce noisiness of "mmco: unref short failure" Do not consider it an error if we have no frames and should discard one.
