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`.

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
Anton Khirnov	8b2e5e42bb	h264: check that an IDR NAL only contains I slices Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9ecabd7892	h264: reset num_reorder_frames if it is invalid An invalid VUI is not considered a fatal error, so the SPS containing it may still be used. Leaving an invalid value of num_reorder_frames there can result in writing over the bounds of H264Context.delayed_pic. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	0652e024c6	h264: reset ref count if decoding the slice header fails Otherwise the ER code might try to use some already freed references. Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	98cc9efc5f	h264: prevent two matching fields from being both a short/long ref combination Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	00dbff4c3e	h264: do not call field_end if we do not have a current picture Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	7f0e81db3c	h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 Higher modes are not allowed for 16x16/chroma, which is what this function is used for. Otherwise this function would return 0 (vertical prediction) for invalid higher modes, which could result in invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	d1b3fabe69	h264: reset first_field if frame_start() fails for missing refs In this case we may not have a current frame, while first_field being set implies we do. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago

Janne Grunau	71617884a2	aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.	11 years ago
Janne Grunau	b7b17ed66e	aarch64: add cpuflags support for NEON and VFP NEON and VFP are currently mandatory for all ARMv8 profiles. Both are handled as extensions as far as cpuflags are concerned. This is consistent with handling x86_64 which always has SSE2, but still handles it as an extension.	11 years ago

Martin Storsjö	2620df1310	mov: Free an earlier allocated array if allocating a new one It could probably also be considered an error if the pointer isn't null at this point, but then we might risk rejecting some slightly broken files that we might have handled so far.

Martin Storsjö	d51f09962d	mov: Free intermediate arrays in the normal cleanup function These arrays are normally freed at the end of mov_read_trak, but make sure they're freed in case mov_read_trak returned early (due to errors) or in case the atoms that allocate arrays are encountered at some other point than within a trak (which we don't have checks against).
