Stefano Sabatini	252746d052	lavu/imgutils: add consistency checks to av_image_copy_plane() Add assertions and abort in case of invalid \|dst_linesize\| < bytewidth or \|src_linesize\| < bytewidth. Avoid to silently corrupt memory.	12 years ago
Stefano Sabatini	c70ec631c9	lavu/opt: add av_opt_ accessors for pixel/format/image size options The interface is implemented against the style of the other options accessors. Possibly simplify programmatic setting of options.	12 years ago
Nicolas George	4cd74c8143	lavu/bprint: implement av_bprint_strftime().	12 years ago
Janne Grunau	8f5587c3d0	cpu.h: define AV_CPU_FLAG_MMX2 for libavutil major 52	12 years ago
Nicolas George	926481078b	lavu/opt: fix av_opt_get_key_value() API. Do not skip the end delimiter. Reserve positive return values. This is an API break, but the function was introduced less than two weeks ago.	12 years ago
Justin Ruggles	5980f5dd18	lavu: rename audioconvert.* to channel_layout.* and deprecate audioconvert.h	12 years ago
Stefano Sabatini	1c6962dc20	lavu: remove disabled FF_API_OLD_EVAL_NAMES code	12 years ago
Justin Ruggles	dfde8a34e5	lavu: add av_ctz() for trailing zero bit count	12 years ago
Stefano Sabatini	74a50e75a8	lavu: drop disabled FF_API_OLD_TC_ADJUST_FRAMENUM code	12 years ago
Nicolas George	3bdf4971ba	lavu/opt: implement av_opt_get_key_value(). This function does the low-level work of av_opt_set_from_string() but can be used when there is no option context or when a generic handling of unknown keys is needed. av_opt_set_from_string() is changed to make use of it.	12 years ago
Stefano Sabatini	481fdeeecf	lavu/opt: add AV_OPT_SAMPLE_FMT option	12 years ago
Nicolas George	483c1aa5f1	lavu/bprint: add av_bprint_get_buffer(). It is useful to use bprint to handle a growing buffer used with another API.	12 years ago
Michael Niedermayer	ae52eb7fc7	lavu: add av_clip64() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	c692957c4e	lavu: remove disabled avoptions cruft	12 years ago
Anton Khirnov	add3a6902e	lavu: bump major to 52 In addition to the recent tables mess, the AVOption defaults behavior changed, so an old lavc used with a new lavu will get completely messed up defaults.	12 years ago
Anton Khirnov	2b8dd371e4	lavu: postpone recent deprecations until the next major bump	12 years ago
Anton Khirnov	00ed7f5958	lavu: remove disabled FF_API_AV_FIFO_PEEK cruft	12 years ago
Anton Khirnov	8207c67a24	lavu: remove disabled FF_API_GET_BITS_PER_SAMPLE_FMT cruft	12 years ago
Nathan Caldwell	a893655bda	avutil: Add AVERROR_EXPERIMENTAL Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Stefano Sabatini	cdea54b4c8	lavu/parseutils: rework rational reduction logic in av_parse_ratio() Avoid to divide num and den by gcd in case of a parsed expression, since that is already done in av_d2q(), and force reduction in case of "a:b" form, allowing to honour the max parameter. The latter change is consistent with the a/b case, and with the documentation.	12 years ago
Michael Niedermayer	183117fed7	libavutil: loose idiotic circular dependancies between version and avutil.h This fixes the recently appearing PIX_FMT warnings Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	d5c62122a7	Move av_reverse table to libavcodec It is only used in that library.	12 years ago
Anton Khirnov	d2fcb356ca	pixdesc: add functions for accessing pixel format descriptors. Make av_pix_fmt_descriptors table static on next major bump. Making the table public is dangerous, since the caller has no way to know how large it actually is. It also prevents adding new fields to AVPixFmtDescriptor without a major bump.	12 years ago
Martin Storsjö	9a92aea27b	avutil: Add functions for allocating opaque contexts for algorithms The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	78071a1420	pixfmt: add AV_ prefixes to PIX_FMT_*	12 years ago
Anton Khirnov	cd15b7c03d	samplefmt: make av_samples_alloc() initialize the data to silence. Right now the buffer is zeroed, which does not represent silence for U8(P).	12 years ago
Stefano Sabatini	85c93d90df	lavu/parseutils: fix av_small_strptime() whitespace directive parsing According to POSIX, strptime() should consume whitespaces in the date string everytime a whitespace conversion specification is found in the date format specification. Make av_small_strptime() conform with this behavior. In particular, should fix trac ticket #1739.	12 years ago
Tim Walker	8919fee7d2	lavu/audioconvert: add a second low frequency channel. Can be used by DTS-HD, TrueHD and E-AC-3, among others. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Stefano Sabatini	29e972f67c	lavu/parseutils: add av_small_strptime() Make internal small_strptime() function public, and use it in place of strptime(). This allows to avoid a dependency on strptime() on systems which do not support it. In particular, fix trac ticket #992.	12 years ago
Stefano Sabatini	5666a1b270	lavu/opt: support NULL and special "none" values for size and pixel format options Allow to specify NULL values explicitly, thus overriding the default values set in the context.	12 years ago
Martin Storsjö	686a329395	avopt: Reorder the default_val struct, making i64 the first field Also mention this change in APIchanges. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Stefano Sabatini	a25346e65c	lavu/opt.h: add AV_OPT_FLAG_FILTERING_PARAM macro	12 years ago
Mans Rullgard	987170cb9d	dict: add av_dict_count() This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Clément Bœsch	4b365b0868	lavu/timecode: add av_timecode_check_frame_rate().	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 years ago
Nicolas George	f893904469	audioconvert: add av_get_standard_channel_layout(). Also bump minor version and add APIchanges entry.	12 years ago
Matthieu Bouron	789f8cb03a	avutil: support 50 and 60 frame rates in timecode api Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	f3e5e6f05b	mem: introduce av_malloc_array and av_mallocz_array Both function ease allocating large arrays implementing the overflow check inside it.	13 years ago
Nicolas George	7beeea8f17	error: define AVERROR_EXTERNAL. This code is intended for errors in external libraries when no corresponding error code can be found. AVERROR_UNKNOWN is too vague for that and looks like AVERROR_BUG.	13 years ago
Diego Biurrun	2047e40e6e	Clarify Doxygen comment for FF_API_* #defines.	13 years ago
Diego Biurrun	86ab7b0f2f	Create version.h headers for libraries that lack them	13 years ago
Stefano Sabatini	e6674e46ec	lavu/imgutils: create misc functions for dealing with buffers Move the lavc/imgconvert functions and rename them as follows: avpicture_get_size -> av_image_get_buffer_size() avpicture_fill -> av_image_fill_arrays() avpicture_layout -> av_image_copy_to_buffer() The new functions have an align parameter, which allows to define the linesize alignment assumed in the buffer (which is set or read). The names of the functions are consistent with the lavu/samples API (av_samples_get_buffer_size(), av_samples_fill_arrays()).	13 years ago
Michael Niedermayer	c41899a377	lavu: split version info into version.h Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
