Ronald S. Bultje	103278f7b0	libavutil/swscale: YUV444P10/YUV444P9 support. Also add missing glue code for recently added YUV422P10 formats to swscale. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Martin Storsjö	cb7c11cc9e	avoptions: Add an av_opt_flag_is_set function for inspecting flag fields Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Michael Niedermayer	6a137dde3e	dict: This code was developed in ffmpeg and not libav, nor by libav developers. Correct copyright notices. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Anton Khirnov	d9f80ea2a7	Move metadata API from lavf to lavu. Rename it to AVDictionary, since it will be used as such. Tags documentation and metadata conversion API is lavf-specific, so remains there.	14 years ago
Stefano Sabatini	a6703faa15	samplefmt: add av_get_bytes_per_sample() Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function. For the moment we don't have sample formats with a non-integer number of bytes, in that case we may need to create a new av_get_bits_per_sample() function. In the meanwhile we prefer to adopt this variant, since avoids divisions by 8 all over the place.	14 years ago

Michael Niedermayer	a39bd458a0	mem: Trying to workaround posix_memalign() bug on OSX This patch is based on a patch by John Stebbins Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Stefano Sabatini	d58ed64a89	eval: add support for pow() function It is a more search-friendly alternative to the ^ operator.	14 years ago
Stefano Sabatini	263f57c6d7	pixdesc: remove duplicated header inclusion	14 years ago
Stefano Sabatini	0bc2cca12f	samplefmt: switch nb_channels/nb_samples params order in av_samples_alloc() This is consistent with the order of parameters in av_samples_fill_arrays().	14 years ago
Stefano Sabatini	e1c7414812	samplefmt: change layout for arrays created by av_samples_alloc() and _fill_arrays() The new layout is consistent with that of the av_image_() API, and simplifies understanding and copy operations, it also preserves alignment information which was lost with the previous layout. This breaks API/ABI, but since the function was never referenced in the code (and it isn't unlikely already used by someone) then this should not be a problem.	14 years ago

Mans Rullgard	d0989bed22	Fix error check in av_file_map() On failure, mmap() returns MAP_FAILED, which may or may not be -1. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	77cd6efc33	ARM: remove volatile from asm statements in libavutil/intmath The volatile qualifiers are not needed on these statements as their effects are fully specified by constraints. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Anton Khirnov	6c117d43c9	AVOptions: set string default values.	14 years ago
Martin Storsjö	80068da3a0	avoptions: Return explicitly NAN or {0,0} if the option isn't found This actually matches what av_get_double did earlier, the 0.0/0.0 division was intentional, for producing NAN. Still keeping the check for the return value from av_get_number, for clarity. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Stefano Sabatini	3c2c52baec	eval: implement not() expression	14 years ago
Ronald S. Bultje	e973557211	Move emms_c() from libavcodec to libavutil.	14 years ago
Stefano Sabatini	6b4c0be558	mem: define the MAX_MALLOC_SIZE constant and use it in place of INT_MAX This makes re-dimensionating the constant simpler, since now it is defined only in one place.	14 years ago
Martin Storsjö	8089b7fa8c	avoptions: Check the return value from av_get_number This avoids doing a division by zero if the option wasn't found, or wasn't an option of an appropriate type. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Diego Biurrun	153382e1b6	multiple inclusion guard cleanup Add missing multiple inclusion guards; clean up #endif comments; add missing library prefixes; keep guard names consistent.	14 years ago

Stefano Sabatini	c0170d0973	imgutils: introduce internal image_get_linesize() and use it Allow to factorize code between av_image_get_linesize() and av_image_fill_linesizes(), and add missing checks. Increase robustness.	14 years ago
Stefano Sabatini	0d73227c71	imgutils: make av_image_get_linesize() return AVERROR(EINVAL) for invalid pixel formats	14 years ago
Stefano Sabatini	10931720cd	imgutils: generalize linesize computation for bitstream formats Make it a subcase of the general algorithm used for the non-bitstream case. Simplify, and make av_image_get_linesize() and av_image_fill_linesizes() correctly return the right value when plane != 0. In particular fix a crash occurring with: -vf format=monow,showinfo,format=monow.	14 years ago

Ivan Kalvachev	518cdff81f	Fix posix_memalign() usage when libavutil is compiled outside FFmpeg. To use posix_memalign() "#define _XOPEN_SOURCE 600" have to be defined. FFmpeg configure defines it from the command line through config.mak, but when libavutil is used outside of FFmpeg the define is missing.

Diego Biurrun	046f081b46	configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS. Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.	14 years ago
Ronald S. Bultje	c8f487deae	swscale: fix YUV420P 9/10bit support. Fix handling of input if not in native endianness, and add support for 9/10-bit output. This allows us to force endianness of YUV420P 9/10bit in the H264/10bit fate tests, which should fix them on big-endian systems.	14 years ago
Michael Niedermayer	a18eff49c0	av_compare_ts: Improve speed when calculations fit in 64bit. about 110 cpu cycles before 60 cpu cycles afterwards. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Baptiste Coudurier	5c511ad4ce	swscale: extend YUV422p support to 10bits depth Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Diego Biurrun	bea705752d	Remove unused softfloat implementation. The softfloat functionality is unused, not installed and incomplete. On platforms without floating point units, the compiler provides a softfloat implementation so there is no point in carrying this code around locally.	14 years ago
Reimar Döffinger	3b6bbfa063	Check syntax even if DEBUG is not defined.	14 years ago
Anton Khirnov	b66752790a	AVOptions: make default_val a union, as proposed in AVOption2. This breaks API and ABI.	14 years ago
Oskar Arvidsson	42239ced65	Add pixel formats for 9- and 10-bit yuv420p. Also add support for these formats in libswscale. Needed for high bit depth h264 decoding. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
