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
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	ea061af15a	configure: formatting cosmetics	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
Diego Biurrun	c35f0e8495	au: Reorder code so that both muxer and demuxer are under #ifdefs This reduces code size when either piece has been disabled.	12 years ago
Diego Biurrun	4d6c96fd69	fate: Move RALF test into lossless audio group	12 years ago
Diego Biurrun	81c7c817a4	cosmetics: Use consistent names for multiple inclusion guards.	12 years ago
Hendrik Leppkes	0cf3505930	avresample: use valid log context in mixing functions Signed-off-by: Justin Ruggles <justin.ruggles@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
Martin Storsjö	e798085f96	rtpdec_vp8: Cosmetics: Fix bad alignment/indentation Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	3b2e8d1d21	rtpenc: Allow including a SDES/CNAME block in RTCP SR packets Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	65e053271a	rtpenc_vp8: Include the picture number in VP8 packets This makes it easier for receivers to decide what to do if data is lost. Refactor calculating the max payload size, to avoid hardcoding the header size in too many places, reducing the number of lines that have to be touched if the header is adjusted further.

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
Justin Ruggles	230acdde26	lavr: move AudioMix struct definition to audio_mix.c	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	0995ad8db4	x86inc: fully concatenate tokens to fix macro expansion for nasm Fixes build errors with nasm introduced in `6f40e9f070` for stack memory alignment. Noticed by BugMaster.	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

Justin Ruggles	c143de40c3	asyncts: fix the asyncts behavior when using the first_pts option Currently it will do padding, but it does not properly handle start-of-stream trimming as documented.	12 years ago
Justin Ruggles	8083332c2d	asyncts: use clipped delta value when setting resample compensation The max_comp option is supposed to limit maximum compensation, but currently the clipped value is not actually used.	12 years ago
