Anton Khirnov	3867f3718b	lavf: remove a pointless check AVStream.codec is always non-NULL	11 years ago
Anton Khirnov	75647dea6f	oggparseogm: check timing variables Fixes a potential divide by zero. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	8058284ce0	lavc: add 422/444 YUV with alpha to align_dimensions() Aligns frame dimensions to 16, which fixes potential invalid writes.	11 years ago
Kostya Shishkov	2f97094608	lagarith: do not call simd functions on unaligned lines 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>	11 years ago
Anton Khirnov	f4a8a00805	sgidec: fix buffer size check in expand_rle_row() Right now it will spuriously fail if the linesize is exactly equal to the data width. CC:libav-stable@libav.org	11 years ago
Anton Khirnov	adb199d1bc	kgv1dec: replace forcing EMU_EDGE by a copy 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.	11 years ago

Anton Khirnov	fffca3d278	4xm: return a proper error code.	11 years ago
Guillaume Martres	060667195e	hevc: rename some HEVC conformance streams 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>	11 years ago
Guillaume Martres	98c0cd0b99	hevc: add new conformance streams Also remove superseded conformance streams.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>	11 years ago
Johan Andersson	7ce88e5ec4	cmdutils: update copyright year to 2014. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Tim Walker	7840c40445	(e)ac3dec: set AV_FRAME_DATA_MATRIXENCODING side data.	11 years ago
Tim Walker	13345fc1f8	(e)ac3: parse and store the Dolby Surround, Surround EX and Headphone mode flags.	11 years ago
Tim Walker	e92123093d	mlpdec: set AV_FRAME_DATA_MATRIXENCODING side data.	11 years ago
Tim Walker	4b7f1a7ced	mlp: Parse TrueHD decoder channel modifiers and set the AVMatrixEncoding for each substream.	11 years ago
Tim Walker	30d70e79a6	dcadec: set AV_FRAME_DATA_MATRIXENCODING side data.	11 years ago
Tim Walker	6bfdb2de88	dcadec: set the output channel mode more accurately. 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.	11 years ago
Tim Walker	5b4797a21d	avframe: add AV_FRAME_DATA_MATRIXENCODING side data type. Includes a libavcodec utility function to update a frame's side data.	11 years ago
Tim Walker	5c437fb672	lavu: Add values for various Dolby flags to the AVMatrixEncoding enum.	11 years ago
Diego Biurrun	52ccc4a0ec	configure: Support preprocessor macros as header names 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>	11 years ago
Martin Storsjö	82b9799bb2	sdp: Check that fmt->oformat is non-null before accessing it This avoids crashes when avserver tries to create an SDP, since `d77f4af`. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Alex Converse	9d18a7d3ec	fate: Update AAC ELD 5.1 ref for recent bugfixes.	11 years ago
Alex Converse	7f29644108	aac: Fix low delay windowing. AAC LD uses a low overlap sine window instead of a KBD window.	11 years ago
Alex Converse	42d1b41983	fate: Add a test vector for AAC ELD with TNS.	11 years ago
Alex Converse	b2212dec0f	aac: Fix TNS decoding for the 512 sample window family.	11 years ago
Alex Converse	e2096e2eaa	fate: Add a downsampled SBR testvector	11 years ago
Martin Storsjö	3348e3492d	arm: Use the matching endfunc macro instead of the assembler directive directly Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	2ad4ee345a	arm: Add a missing endfunc macro call Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Anton Khirnov	a3a55645f0	mpegvideo: remove disabled bfin asm It has been disabled as 'broken' over 3 years ago in `b716a792`	11 years ago
Anton Khirnov	a4d0c6e050	mpegvideo: move dct_unquantize functions up to avoid forward declarations	11 years ago
Anton Khirnov	aec25b1c46	mpegvideo: split the encoding-only parts of frame_start() into a separate function This introduces some code duplication. However, much of it should go away once the decoders stop using MpegEncContext.	11 years ago
Anton Khirnov	b318106fae	FATE: add a test for the lavr mixing case fixed in `fc6a3ef40d`	11 years ago
Anton Khirnov	a8cc88b1a2	tests/Makefile: allow FILTER* to be called with lists of filter names	11 years ago
Anton Khirnov	cc976a75df	audio_mix: print (SKIP) instead of 0.0 for matrix columns removed along with output zeroing	11 years ago
Anton Khirnov	fc6a3ef40d	audio_mix: fix zeroing output channels in certain cases 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	11 years ago
Anton Khirnov	3d95d27376	audio_mix: initialize the data pointers to NULL 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.	11 years ago
Anton Khirnov	58312b2472	h264: reset data_partitioning if decoding the slice header for NAL_DPA fails 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	11 years ago
Anton Khirnov	e89aa4bf56	lzw: switch to bytestream2 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	1b5d065ca7	pmpdec: check that there is at least one audio packet. The code cannot handle there being none, but that should not happen for valid files. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	94a417acc0	mathematics: remove asserts from av_rescale_rnd() It is a public function, it must not assert on its parameters.	11 years ago
Anton Khirnov	24057c8320	eacmv: check the framerate before setting it. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago

Anton Khirnov	a6a2282c25	rv30: fix extradata size check. 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	11 years ago
Anton Khirnov	feded990e3	mpegvideo: set reference/pict_type on generated reference frames 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	11 years ago
Anton Khirnov	58f0d164de	Makefile: add html template files to the doxygen deps	11 years ago

Diego Biurrun	b83d1ee3b4	avutil: Move library version related macros to version.h This is a more sensible place for these macros.	11 years ago
