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
Martin Storsjö	0eed5016a2	avoptions: Support getting flag values using av_get_int	14 years ago
Michael Niedermayer	9132f2ad0c	eval: opensolaris strtod() cannot handle 0x1234 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Mans Rullgard	1550f45a89	Add av_clip_uintp2() function Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Michael Niedermayer	f0eb373f9d	pixfmt-Comment: Fix big/little typo Found-by: kierank Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Michael Niedermayer	08675bb399	mem: Choose alignment at compile time depending on AVX enabledness. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Michael Niedermayer	1735440773	fifo: use av_freep() With this change libavutil uses av_freep() everywhere where it makes sense. Remaining av_free() use in it has the used pointer become inaccessible quickly soo zeroing makes no sense. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago

Stefano Sabatini	bebe72f4a0	lavc: deprecate FF__TYPE macros in favor of AV_PICTURE_TYPE_ enums Also deprecate av_get_pict_type_char() in favor of av_get_picture_type_char(). The new enum and av_get_picture_type_char() are defined in libavutil. This allows the use in libavfilter without the need to link against libavcodec.

Jason Garrett-Glaser	15919ee48f	bswap: use native types for av_bwap16(). This prevents a call to bytestream_get_be16() using a movzwl both before and after the ror instruction, which is obviously inefficient. Arm uses the same trick also. Sintel decoding goes from (avg+SD) 9.856 +/- 0.003 to 9.797 +/- 0.003 sec. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Stefano Sabatini	22180e7a5a	error: remove symbols which were deprecated before the big bump The removal was not applied when merging the Libav patches, because there was still code referencing the symbols. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it>	14 years ago

Anton Khirnov	a975dbc86b	error: change AVERROR_EOF value The current value is masking the POSIX error code EPIPE, which has a different semantics. This breaks API. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	79157f400b	error: remove AVERROR_NUMEXPECTED AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and has a too much specific meaning, which is better explained through a log message. Thus it can be replaced by AVERROR(EINVAL). This breaks API. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	58f8463947	error: add error code AVERROR_OPTION_NOT_FOUND, and use it in opt.c The new error code is better than AVERROR(ENOENT), which has a completely different semantics ("No such file or directory").
