Anton Khirnov	8adfacff5c	zmbv: remove some pointless comments and empty lines	12 years ago
Anton Khirnov	c6303f8d70	yop: simplify/sanitize the decoding loop Do not overwrite linesize set by get_buffer(). The last frame in the FATE test is not decoded anymore, since the file is cut and a part of it is missing.	12 years ago

Anton Khirnov	3eab600752	bmp: cosmetics, reformat	12 years ago
Martin Storsjö	0940580adb	lavc: Correct the description of pkt_dts The description as updated in 6e5c44b0f made it sound like it is handled exactly like the pts, which it is not. Clarify that it is the packet that triggered returning the frame instead of just the last avpacket (in case of frame threading, it won't be the dts of the last packet).

Anton Khirnov	418693bdc5	lavc: rewrite and extend AVFrame doxy	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
Justin Ruggles	aef5150719	flac: only set channel layout if not previously set or on channel count change Fixes Bug 402	12 years ago
Diego Biurrun	511cf612ac	miscellaneous typo fixes	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
Anton Khirnov	5823686261	mpeg12: do not decode extradata more than once. Fixes CVE-2012-2803. CC: libav-stable@libav.org	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
Janne Grunau	acb571c89a	avcodec: bump minor for adaptive h264 frame-mt Also adds forgotten Changelog entry.	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
Janne Grunau	73ad2c2fa7	h264: increase dist_scale_factor for up to 32 references Compute dist_scale_factor_field only for MBAFF since that is the only case in which it is used.	12 years ago
Diego Biurrun	523c7bd23c	misc typo, style and wording fixes	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

Janne Grunau	a421bbfe83	h264: fix memleak on error during SPS parsing Introduced in `d7d6efe42b`.	12 years ago
Janne Grunau	27c8337e59	h264-mt: handle NAL_DPAs before calling ff_thread_finish_setup Since a NAL_DPA can start a new frame it has to be handled before ff_thread_finish_setup is called.	12 years ago
Luca Barbato	f33b5ba63e	vp56: release frames on error Fixes CVE-2012-2783 CC: libav-stable@libav.org	12 years ago
Luca Barbato	bb675d3ac6	vp56: make parse_header return standard error codes Returning 0 for failure is misleading. CC: libav-stable@libav.org	12 years ago

Janne Grunau	0eae920c3c	h264: initialize frame-mt context copies properly	12 years ago
Janne Grunau	6a27ae28f9	mpegvideo: treat delayed pictures as used This requires to move the avcodec_default_free_buffers() call to ff_MPV_common_end() since otherwise delayed pictures would get freed during a size change.	12 years ago
Janne Grunau	bd255f9feb	lavc: set frame parameters after decoding only if necessary Direct rendering capable decoders call get_buffer() which will set the frame parameters. Prevents frames with wrong parameters when a decoder outputs delayed frames after a resolution or pixel format change.	12 years ago
Janne Grunau	072be3e896	h264: set parameters from SPS whenever it changes Fixes a crash in the fuzzed sample sample_varPAR.avi_s26638 with alternating bit depths.	12 years ago
Luca Barbato	be75fed975	vp6: properly fail on unsupported feature Interlacing is not supported at all and mismanaged down the normal codepaths causing possible buffer management issues. CC: libav-stable@libav.org	12 years ago
