* libopusenc: Change default frame duration to 20 msPaul B Mahol2014-01-06
| | | | | | | 20 ms is the default in the libopus encoder, and gives better quality than 10 ms. Signed-off-by: Martin Storsjö <martin@martin.st>
* pthread_frame: unref decoded frames on failureAnton Khirnov2014-01-06
| | | | | | | This is similar to what the non-threaded code already does. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: do not use 422 functions for monochromeAnton Khirnov2014-01-06
| | | | | | | Fixes invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: check that execute_decode_slices() is not called too many timesAnton Khirnov2014-01-06
| | | | | | | Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* 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
* cavsdec: check ff_get_buffer() return valueAnton Khirnov2014-01-06
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* lavc: do not leak the internal frame if opening the codec failsAnton Khirnov2014-01-06

* 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.

|
* 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.
* aac: Fix low delay windowing.Alex Converse2014-01-04
| | | | AAC LD uses a low overlap sine window instead of a KBD window.
* aac: Fix TNS decoding for the 512 sample window family.Alex Converse2014-01-04

* mpegvideo: remove disabled bfin asmAnton Khirnov2014-01-03
| | | | It has been disabled as 'broken' over 3 years ago in b716a792
* mpegvideo: move dct_unquantize functions up to avoid forward declarationsAnton Khirnov2014-01-03
|
* mpegvideo: split the encoding-only parts of frame_start() into a separate ↵Anton Khirnov2014-01-03
| | | | | | | function This introduces some code duplication. However, much of it should go away once the decoders stop using MpegEncContext.
* 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
| | | | | | | | It has been checking the number of bits in the offset instead of the actual offset. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* 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

* vc1: Fix intensity compensation performance regressionMason Carter2013-12-22
| | | | | | | | | | | Introduced by 28243b0d35b47bbf9abbd454fc444a6e0a9e7b71 Intensity compensation is always used once it was encountered, because v->next_use_ic is never set back to zero. Reset v->next_use_ic, when resetting v->next_luty/uv. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
