* Move code shared between libdirac and libschroedinger to libschroedinger.Diego Biurrun2012-05-07
| | | | | This also involves making some function static and changing the name prefixes of some functions and structures.

* lavc: add sample rate and channel layout to AVFrame.Anton Khirnov2012-05-07
| | | | Rationale is the same as for video width/height etc.
* zerocodec: check if the previous frame is missingPaul B Mahol2012-05-06
| | | | | | | | | ZeroCodec relies on the keyframe flag being set in the container, and prev is the previously decoded frame. A keyframe flags incorrectly set will lead to this condition. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* 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>

* 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

* 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>

* 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
