* miscellaneous typo fixesDiego Biurrun2012-12-21

* lavc: add missing files for armLuca Barbato2012-12-20
| | | | Across the many retouches those did not make the main commit.
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | 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>
* mpeg12: do not decode extradata more than once.Anton Khirnov2012-12-19
| | | | | | Fixes CVE-2012-2803. CC: libav-stable@libav.org
* h264: fix sps parsing for SVC and CAVLC 4:4:4 Intra profilesVictor Lopez2012-12-19
| | | | | | Fixes bug 396. CC: libav-stable@libav.org
* mpegvideo: increase edge_emu_buffer size for VC1Janne Grunau2012-12-19
| | | | | | | | | The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma and needs more space. That was not a problem before f1d8763a02b5fce 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.
* avcodec: bump minor for adaptive h264 frame-mtJanne Grunau2012-12-18
| | | | Also adds forgotten Changelog entry.
* h264: support frame parameter changes during frame-mtJanne Grunau2012-12-18
| | | | Fixes CVE-2012-2782.
* mpegvideo: allocate scratch buffers after linesize is knownJanne Grunau2012-12-18
| | | | | | | | | | | 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.
* ff_h264_direct_ref_list_init: fix B slice check.Michael Niedermayer2012-12-18
| | | | | | Fixes null pointer dereference. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
* h264: increase dist_scale_factor for up to 32 referencesJanne Grunau2012-12-18
| | | | | Compute dist_scale_factor_field only for MBAFF since that is the only case in which it is used.
* misc typo, style and wording fixesDiego Biurrun2012-12-18
|
* h264: use mbaff ref indices in fill_colmap() only for mbaff referencesMichael Niedermayer2012-12-18
| | | | | | Prevents writing beyond array bounds. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* h264: prevent decoding of slice NALs in extradataJanne Grunau2012-12-18
| | | | | | | | 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.
* cosmetics: Use consistent names for multiple inclusion guards.Diego Biurrun2012-12-17
|
* h264: fix memleak on error during SPS parsingJanne Grunau2012-12-15
| | | | Introduced in d7d6efe42b0d.
* h264-mt: handle NAL_DPAs before calling ff_thread_finish_setupJanne Grunau2012-12-15
| | | | | Since a NAL_DPA can start a new frame it has to be handled before ff_thread_finish_setup is called.
* vp56: release frames on errorLuca Barbato2012-12-14
| | | | | | Fixes CVE-2012-2783 CC: libav-stable@libav.org
* vp56: make parse_header return standard error codesLuca Barbato2012-12-14
| | | | | | Returning 0 for failure is misleading. CC: libav-stable@libav.org
* ivi_common: check that scan pattern is set before using it.Anton Khirnov2012-12-14
| | | | | | Fixes CVE-2012-2791. CC: libav-stable@libav.org
* ivi_common: use proper logging context in ivi_decode_blocks().Anton Khirnov2012-12-14
|
* ivi_common: make some functions and tables static.Anton Khirnov2012-12-14
|
* h264: initialize frame-mt context copies properlyJanne Grunau2012-12-13
|
* mpegvideo: treat delayed pictures as usedJanne Grunau2012-12-13
| | | | | | 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.
* lavc: set frame parameters after decoding only if necessaryJanne Grunau2012-12-13
| | | | | | | | 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.
* h264: set parameters from SPS whenever it changesJanne Grunau2012-12-13
| | | | | Fixes a crash in the fuzzed sample sample_varPAR.avi_s26638 with alternating bit depths.
* vp6: properly fail on unsupported featureLuca Barbato2012-12-13
| | | | | | | Interlacing is not supported at all and mismanaged down the normal codepaths causing possible buffer management issues. CC: libav-stable@libav.org
* aacdec: Fix an off-by-one overwrite when switching to LTP profile from MAIN.Alex Converse2012-12-12

* lavc: replace some forgotten instances of PixelFormat with AVPixelFormatAnton Khirnov2012-12-12
|
* svq1: unmacroify macros used only once.Anton Khirnov2012-12-12
|
* svq1: deMpegEncContextizeAnton Khirnov2012-12-12
| | | | | This decoder is quite simple and none of the MpegEncContext complexity is actually needed.
* x86inc: support stack mem allocation and re-alignment in PROLOGUERonald S. Bultje2012-12-12
| | | | | | | Use this in VP8/H264-8bit loopfilter functions so they can be used if there is no aligned stack (e.g. MSVC 32bit or ICC 10.x). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* Make LOCAL_ALIGNED syntactically similar on all systemsMans Rullgard2012-12-11
| | | | | | | | | This changes the LOCAL_ALIGNED definition on systems where DECLARE_ALIGNED is used so it matches the manual alignment case, ensuring invalid use will not compile on x86 only to fail on everything else. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ZeroCodec: Flip outputCarl Eugen Hoyos2012-12-10
| | | | | | | | | | The initial testing of the VFW binary codec was flawed, likely due to an AviSynth bug. Re-testing using VirtualDub and various professional editing applications has revealed it should have been flipped. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* sh4: dsputil: remove duplicate of ff_gmc_c()Mans Rullgard2012-12-10

* mjpeg: initialize input padding after unescaped buffer to zeroJanne Grunau2012-12-08
| | | | | | Fixes valgrind --undef-value-errors=yes warnings caused by valid overreads in the fate vsynth jpegls, cover-art-ape and cover-art-wv tests.
* h264: check for invalid zeros_left before writingRonald S. Bultje2012-12-08
| | | | | | | Prevent an invalid write into coeffs[scantable[-1]] if zeros_left itself was an invalid VLC code (and thus -1). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* golomb: use unsigned arithmetics in svq3_get_ue_golomb()Janne Grunau2012-12-08
| | | | | | | | | | This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.
