* WMAL: Restore removed code in mclms_predict()Mashiat Sarker Shakkhar2012-05-05
| | | | | | Based on observations made by Jakub Stachowski <qbast@go2.pl> Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* png: check bit depth for PAL8/Y400A pixel formats.Ronald S. Bultje2012-05-04
| | | | | | | | Wrong bit depth can lead to invalid rowsize values, which crashes the decoder further down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* celp filters: Do not read earlier than the start of the 'out' vector.Alex Converse2012-05-04
| | | | CC: libav-stable@libav.org
* vqavideo: return error if image size is not a multiple of block sizeMans Rullgard2012-05-03
| | | | | | | | | | | The decoder assumes in various places that the image size is a multiple of the block size, and there is no obvious way to support odd sizes. Bailing out early if the header specifies a bad size avoids various errors later on. Fixes CVE-2012-0947. Signed-off-by: Mans Rullgard <mans@mansr.com>

* motionpixels: Clip YUV values after applying a gradient.Alex Converse2012-05-02
| | | | | | Prevents illegal reads on truncated and malformed input. CC: libav-stable@libav.org
* jpeg: handle progressive in second field of interlaced.Ronald S. Bultje2012-05-02
| | | | | | | | Progressive data is allocated later in decode_sof(), not allocating that data leads to NULL dereferences. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* h263: more strictly forbid frame size changes with frame-mt.Ronald S. Bultje2012-05-02
| | | | | | | Prevents crashes because the old check was incomplete. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* h264: additional protection against unsupported size/bitdepth changes.Ronald S. Bultje2012-05-02
| | | | | | | Fixes crashes in codepaths not covered by original checks. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* tta: prevents overflows for 32bit integers in header.Ronald S. Bultje2012-05-02
| | | | | | | | This prevents sample_rate/data_length from going negative, which caused various crashes and undefined behaviour further down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* vp8: update frame size changes on thread context switches.Ronald S. Bultje2012-05-02
| | | | | | | | | This properly synchronizes frame size changes between threads if subsequent threads abort decoding before frame size is initialized, i.e. it prevents the thread after that from ping-ponging back to the original value. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
* snowdsp: explicitily state instruction size.Ronald S. Bultje2012-05-02

| | | | | | | | The index of the motion vector has to be checked before being multiplied by 2 for the array index. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* twinvq: fix out of bounds array accessMans Rullgard2012-05-01
| | | | | | | | | ModeTab.fmode has only 3 elements, so indexing it with ftype in the initialier for 'size' is invalid when ftype == FT_PPC. This fixes crashes with gcc 4.8. Signed-off-by: Mans Rullgard <mans@mansr.com>
* WMAL: do not output last frame again if nothing was decoded in current packetJakub Stachowski2012-05-01

* WMAL: do not start decoding if frame does not end in current packetMashiat Sarker Shakkhar2012-05-01
| | | | | | | This fixes decoding of frames which span more than two packets. Tested with recit24.wma. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* adpcm-thp: fix invalid array indexingMans Rullgard2012-05-01

* ppc: remove shift parameter from scalarproduct_int16_altivec()Mans Rullgard2012-05-01
| | | | | | | The shift parameter was removed from this interface in 7e1ce6a. This updates the Altivec implementation to match. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: dsputil: do unaligned block accesses correctlyMans Rullgard2012-05-01
| | | | | | | | | | | | To load unaligned vector data in the usual way, explicit vec_ld() should be used rather than dereferencing a pointer to a vector type. When the VSX extension is enabled, gcc may compile vector pointer dereferences using the VSX lxvw4x instruction instead of the lvx instruction typically used with Altivec/VMX. As the behaviour of these instructions with unaligned addresses differs, it is important that only lvx is used here. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dvenc: do not call dsputil functions with stride not a multiple of 16Mans Rullgard2012-05-01
| | | | | | | | Allowing dsputil functions to assume the stride is a multiple of 16 even for smaller block sizes can simplify their implementation. This appears to be the only place this guarantee is not met. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avcodec: introduce YCoCg colorspaceHendrik Leppkes2012-04-29
| | | | | | | | Non perceptual color model that aims to have an increase effectiveness in compression like the normal YCbCr while having near-lossless/lossless mapping to RGB. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* h264: new assembly version of get_cabac for x86_64 with PICRoland Scheidegger2012-04-28
| | | | | | | | | | This adds a hand-optimized assembly version for get_cabac much like the existing one, but it works if the table offsets are RIP-relative. Compared to the non-RIP-relative version this adds 2 lea instructions and it needs one extra register. get_cabac() gets about 40% faster, for an overall speedup of about 5%. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* h264: use one table instead of several for cabac functionsRoland Scheidegger2012-04-28
| | | | | | | | | | | | | The reason is this is easier for PIC code (in particular on darwin...). Keep the old names as pointers (static in cabac_functions.h so gcc knows these are just immediate offsets) so the c code can nicely stay the same (alternatively could use offsets directly in the functions needing the tables). This should produce the same code as before with non-pic and better code (confirmed) with pic. The assembly uses the new table but still won't work for PIC case. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
