Justin Ruggles	d02202e08a	opt: avoid segfault in av_opt_next() if the class does not have an option list CC: libav-stable@libav.org	12 years ago
Justin Ruggles	5778299c7e	ttadec: fix last frame handling when seeking Using a frame count, as is done currently, does not work at all with seeking. Instead, when the number of samples in the final frame has been decoded, we check if only the 32-bit CRC is remaining. If so, we assume that it is the final frame. There is no longer a need to keep total_frames in TTAContext.	12 years ago
Justin Ruggles	68a04b0cce	alacdec: do not be too strict about the extradata size Sometimes the extradata has duplicate atoms, but that shouldn't prevent decoding. Just ensure that it is at least 36 bytes as a sanity check. CC: libav-stable@libav.org	12 years ago

Martin Storsjö	c7d4de3d73	rtpdec_vp8: Don't return known-broken packets This is built on the assumption that the first partition of each VP8 packet is essential for decoding any later packet - if this partition is broken/missed, the arithmetic coder gets out of sync and decoding the bitstream in further packet ends up with total garbage. If packets of a frame are lost, make sure the first partition is intact (return only this part of the packet, nothing else), otherwise stop returning data until the next keyframe is received. Alternatively, one would simply not return any packets at all until the next keyframe, if packet loss is detected. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	90c784cc13	rtpdec: Pass the sequence number to depacketizers This allows depacketizers to figure out if packets have been lost. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	0a0e340f5b	configure: Make avconv depend on null, anull and resample filters Building avconv without that functionality makes little sense.	12 years ago
Diego Biurrun	69f086e0f9	build: avfilter: Remove duplicate compilation entry for vf_scale vf_scale should not be unconditionally compiled even if disabled.	12 years ago

Luca Barbato	6906b19346	lavc: add missing files for arm Across the many retouches those did not make the main commit.	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Martin Storsjö	a925f723a9	rtp: Don't read priv_data unless it is allocated This makes all users of rtpenc_chain (rtsp muxer, sapenc, mov rtp hinting) work again, broken since `8034130e0`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Björn Axelsson	1eaff98c83	flvenc: Check whether seeking back to the header succeeded The FLV muxer tries to update the header in write_trailer, which is impossible if writing to a pipe or network stream. Don't write header data if seeking to the header fails. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Jernej Virag	e30e8e311e	sapenc: Pass the title on to the chained muxers This makes sure it ends up in the SDP, providing a proper session name in the SAP announcements. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Justin Ruggles	b2fe6756e3	lavr: add option for dithering during sample format conversion to s16	12 years ago
Anton Khirnov	5823686261	mpeg12: do not decode extradata more than once. Fixes CVE-2012-2803. CC: libav-stable@libav.org	12 years ago
Anton Khirnov	c661cb6672	cmdutils: pass number of groups to split_commandline(). This makes the code simpler and avoids mixing designated and non-designated initializers in a potentially unsafe way in avconv.	12 years ago
Janne Grunau	bb2bab92e7	mov: handle h263 and flv1 for codec_tag 'H','2','6','3' The sample in https://bugzilla.libav.org/show_bug.cgi?id=393 and samples/F4V/H263_NM_f.mp4 both have codec_tag H263 for different codecs. H263 is apparently used by Flash Media Server for Sorensen Spark videos. Patch based on commit `5442083b1c` by Carl Eugen Hoyos. Fixes bug 393.	12 years ago
Victor Lopez	1c8bf3bfed	h264: fix sps parsing for SVC and CAVLC 4:4:4 Intra profiles Fixes bug 396. CC: libav-stable@libav.org	12 years ago
Janne Grunau	45635885e4	mpegvideo: increase edge_emu_buffer size for VC1 The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma and needs more space. That was not a problem before `f1d8763a02` since the size for edge_emu_buffer was always calculated with 2 byte per pixel since the linesize was not known. Fixes occasionally fate errors in vc1_sa10143.	12 years ago
Ronald S. Bultje	a34d9ad969	lavc: merge latest x86inc.asm fixes with x264 Unbreak NASM support. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Janne Grunau	acb571c89a	avcodec: bump minor for adaptive h264 frame-mt Also adds forgotten Changelog entry.	12 years ago
Anton Khirnov	e82cb79adf	avconv: pass the actually selected decoder to filter_codec_opts().	12 years ago
Anton Khirnov	77bd1bc73a	avconv: use new options parser.	12 years ago
Anton Khirnov	0ec1642b60	cmdutils: don't log an error in opt_default(). It results in spurious errors when using the new preparser.	12 years ago
Anton Khirnov	8c9af5b205	cmdutils: add a commandline pre-parser. It splits the commandline into a more convenient internal representation for further parsing. This will allow e.g. - processing global options first independently of their location on the commandline, eliminating ugly hacks for processing e.g. cpuflags first - better options validation and error reporting. It is now possible for the parser to know that it's applying an input option to an output file or vice versa and act accordingly.	12 years ago
Anton Khirnov	a01c02bcff	cmdutils: split parse_option(). Separate the code that searches for the option to use and the code that actually writes it. The writing code will be reused by the new options parser.	12 years ago
Anton Khirnov	10bca66101	cmdutils: add a macro to simplify grow_array() calls.	12 years ago
Janne Grunau	9e696d2e5f	h264: support frame parameter changes during frame-mt Fixes CVE-2012-2782.	12 years ago
Janne Grunau	f1d8763a02	mpegvideo: allocate scratch buffers after linesize is known Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.	12 years ago
Michael Niedermayer	ed2d7d5868	ff_h264_direct_ref_list_init: fix B slice check. Fixes null pointer dereference. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	12 years ago

Michael Niedermayer	c9aab8a123	h264: use mbaff ref indices in fill_colmap() only for mbaff references Prevents writing beyond array bounds. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago
Janne Grunau	61c6eef545	h264: prevent decoding of slice NALs in extradata It is not posible to call get_buffer during frame-mt codec initialization. Libavformat might pass huge amounts of data as extradata after parsing broken files. The 'extradata' for the fuzzed sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains multiple slices.	12 years ago
Derek Buitenhuis	26e4f0c70f	doxy: Clarify what avpriv_set_pts_info does The "pts for a given stream" was nonsensical. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago

Justin Ruggles	f1c2915ce1	lavr: remove automatic context close/open for resampling compensation It adds unnecessary complication for insignificant usability improvement. The user really should know if they'll need resampling compensation before opening the context. Note that only the documentation has changed. The current functionality will still work until the next major bump.	12 years ago
Justin Ruggles	f322b20735	lavr: only save/restore the mixing matrix if mixing is being done	12 years ago
