* h264: reject mismatching luma/chroma bit depths during sps parsingAnton Khirnov2014-01-06
| | | | | | | | | | There is no point in delaying the check and it avoids bugs with a half-initialized context. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: rebuild the default ref list if the reference count changesAnton Khirnov2014-01-06
| | | | | | | Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org

* lavf: remove a pointless checkAnton Khirnov2014-01-06
| | | | AVStream.codec is always non-NULL
* oggparseogm: check timing variablesAnton Khirnov2014-01-06
| | | | | | | Fixes a potential divide by zero. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* lavc: add 422/444 YUV with alpha to align_dimensions()Anton Khirnov2014-01-06
| | | | Aligns frame dimensions to 16, which fixes potential invalid writes.
* lagarith: do not call simd functions on unaligned linesKostya Shishkov2014-01-06
| | | | | | | | | | They end up overwriting past the line end. Partially based on a patch by Michael Niedermayer <michaelni@gmx.at> Bug-Id: vlc/9700 Signed-off-by: Luca Barbato <lu_zero@gentoo.org> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* sgidec: fix buffer size check in expand_rle_row()Anton Khirnov2014-01-06
| | | | | | | Right now it will spuriously fail if the linesize is exactly equal to the data width. CC:libav-stable@libav.org
* kgv1dec: replace forcing EMU_EDGE by a copyAnton Khirnov2014-01-06
| | | | | | | | | | | The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on get_buffer2() to always provide buffers with linesize == 2 * width. This is wrong, since we place no such restriction on get_buffer2() implementations. Fix this by decoding into internal buffers and copying them to output frames. Since this is a very obscure decoder, the performance hit should not be an issue.

* hevc: rename some HEVC conformance streamsGuillaume Martres2014-01-06
| | | | | | | | | Some HEVC conformance streams zip on http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/draft_conformance/ were updated without changing the actual stream. Rename them in FATE accordingly to make it easier to track future stream updates. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* hevc: add new conformance streamsGuillaume Martres2014-01-06
| | | | | | | Also remove superseded conformance streams. The conformance streams all come from http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/draft_conformance/ Signed-off-by: Anton Khirnov <anton@khirnov.net>

* dcadec: set the output channel mode more accurately.Tim Walker2014-01-05
| | | | | | When downmixing 2.1 to 2-channel, if the 2.0 portion is Lt/Rt, sum-difference or dual mono, the actual output will be the same (with the LFE either mixed-in or discarded). Also, when downmixing an arbitrary layout to 2-channel, if the bitstream contains custom downmix coefficients targeting Lt/Rt, then the output will be Lt/Rt rather than regular Stereo.
* avframe: add AV_FRAME_DATA_MATRIXENCODING side data type.Tim Walker2014-01-05
| | | | Includes a libavcodec utility function to update a frame's side data.

* configure: Support preprocessor macros as header namesDiego Biurrun2014-01-05
| | | | | | | | | | New versions of FreeType have moved the location of their API header(s) and hide the location behind a macro. Since the location changes between versions and no other way to know the location exists, this workaround becomes necessary. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* sdp: Check that fmt->oformat is non-null before accessing itMartin Storsjö2014-01-05

* audio_mix: fix zeroing output channels in certain casesAnton Khirnov2014-01-03
| | | | | | | | | | | Specifically, when the corresponding input channel exists and its matrix column is all-zero (which is necessary for zeroing the output), the matrix column must be removed from the matrix. This is not done currently, so the mixing code would end up using uninitialized pointers from stack. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
* audio_mix: initialize the data pointers to NULLAnton Khirnov2014-01-03
| | | | | | | This should make it easier to catch problems where some of those pointers are used uninitialized, since reading from NULL should always crash, while random numbers from stack can turn out to be valid pointers, so random memory may be silently overwritten.
* h264: reset data_partitioning if decoding the slice header for NAL_DPA failsAnton Khirnov2014-01-03
| | | | | | | | If it was set before then we can end up trying to decode a slice without a valid slice header, which can lead to invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org

* rv30: fix extradata size check.Anton Khirnov2014-01-03

* mpegvideo: set reference/pict_type on generated reference framesAnton Khirnov2014-01-03
| | | | | | | | | Otherwise the generic code will unref them, which can then result in last_picture_ptr == current_picture_ptr, which causes deadlocks at least in rv40. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
