Anton Khirnov	85afbb1d00	AVOptions: don't segfault on NULL parameter in av_set_options_string()	13 years ago
Michael Niedermayer	da31e537c4	opt: handle AV_OPT_TYPE_CONST too Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
Anton Khirnov	3b3ea34655	Remove all uses of deprecated AVOptions API.	13 years ago
Anton Khirnov	8c5dcaad13	AVOptions: add av_opt_next, deprecate av_next_option. Just for naming consistency, no functional changes.	13 years ago
Anton Khirnov	dca055be3a	AVOptions: add functions for evaluating option strings.	13 years ago
Anton Khirnov	059a037fbd	AVOptions: split get_number(). Split actual writing to read_number() in the same way as write_number(). Allows set_string_number() to write to a caller-provided destination.	13 years ago
Anton Khirnov	41d9d51a72	AVOptions: add av_opt_get, deprecate av_get. New functions can get values from child objects, properly report error codes and have consistent naming and signatures.	13 years ago
Anton Khirnov	dac66da63d	AVOptions: add av_opt_set(). Deprecate av_set_ New functions support setting values on children, return error codes instead of options and have consistent naming and signatures.	13 years ago
Anton Khirnov	641c7afe3c	AVOptions: add new API for enumerating children. This will allow the caller to enumerate child contexts in a generic way and since the API is recursive, it also allows for deeper nesting (e.g. AVFormatContext->AVIOContext->URLContext) This will also allow the new setting/reading API to transparently apply to children contexts.	13 years ago
Anton Khirnov	7bb1807c2d	AVOptions: refactor set_number/write_number write_number() does the actual writing of the supplied number to destination. Move finding the option and choosing destination address out of it.	13 years ago
Anton Khirnov	cf10095f0b	AVOptions: cosmetics, rename static av_set_number2() to write_number().	13 years ago
Anton Khirnov	b003d0be5b	AVOptions: cosmetics, move and rename static av_set_number().	13 years ago
Anton Khirnov	c8d787d2ef	AVOptions: split av_set_string3 into opt type-specific functions Also stop attempting to honor the alloc parameter, as things break horribly in that case. It will be removed in upcoming successor to av_set_string3.	13 years ago
Michael Niedermayer	0962ad0e2f	avopt: Fix searching for constants Fixes Ticket350 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	4dbcdfa86d	AVOptions: remove AVOption.offset <= 0 checks They will only ever be <=0 if the option is broken, in which case this check is hiding a bug.	13 years ago
Anton Khirnov	79eff91325	AVOptions: deprecate av_opt_set_defaults2 It's a hack which was created to allow for multiple options with different defaults to refer to same field (e.g. 'b' vs 'ab'). There is no need for it anymore.	13 years ago
Anton Khirnov	a7e2b2ccc9	AVOptions: move doxy for av_opt_set_defaults() from opt.c to opt.h Also change it to be more readable.	13 years ago
Anton Khirnov	bea5670a4f	AVOptions: drop av_ prefix from static av_get_number().	13 years ago
Michael Niedermayer	c4fd1d34ca	av_get_string: search children too. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	bf71fb54b5	av_get_number: also search children, this is more sane than not doing so. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	a726d7fd4e	AVOptions: in av_opt_find() don't return named constants unless unit is specified. That is, unless the caller explicitly asks for them. Prevents conflict between e.g. the 'loop' option in img2 demuxer and 'loop' flag in AVCodecContext.	14 years ago
Mans Rullgard	abc78a5a7c	Do not include log.h in avutil.h Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	add41decd9	Remove return statements following infinite loops without break These statements cannot be reached and are thus not needed. This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	ce1e181b13	opt-test: Add missing braces to silence compiler warnings. libavutil/opt.c:604:1: warning: missing braces around initializer [-Wmissing-braces]	14 years ago
Stefano Sabatini	141f03541b	opt: do not crash in av_set_options_string() if opts == NULL Add missing NULL check, and update documentation accordingly.	14 years ago
Anton Khirnov	dc59ec5e79	AVOptions: add av_opt_find() as a replacement for av_find_opt.	14 years ago
Anton Khirnov	7e83e1c511	AVOptions: add av_opt_set_dict() mapping a dictionary struct to a context. This way the caller can pass all the options in one nice package.	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
Anton Khirnov	b39b06233d	AVOptions: add av_opt_free convenience function.	14 years ago
Michael Niedermayer	87ababd7c5	avopt: fix segfault Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
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
Martin Storsjö	0eed5016a2	avoptions: Support getting flag values using av_get_int	14 years ago
Anton Khirnov	b66752790a	AVOptions: make default_val a union, as proposed in AVOption2. This breaks API and ABI.	14 years ago
Michael Niedermayer	3862ebba23	AVOptions: av_set_string3() allow NULL strings Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Anton Khirnov	85770f2a26	AVOptions: make default_val a union, as proposed in AVOption2. This breaks API and ABI.	14 years ago
Anton Khirnov	5a43bd5e26	options: simplify av_find_opt by using av_next_option.	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"). Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	d2af7205a1	Use hierarchic names convention (prefix them with av_expr) for the eval API. More grep-friendly and more consistent with the rest of the FFmpeg API. Originally committed as revision 25708 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	584b8edb99	Add missing case for FF_OPT_TYPE_DOUBLE in av_opt_set_defaults2(). Originally committed as revision 25265 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	c85eef4ed8	Move av_set_options_string() from libavfilter to libavutil. Originally committed as revision 25236 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	be0e596a57	Simplify include, since opt.c is now in libavutil there is no need to use the library path prefix for eval.h. Originally committed as revision 25220 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	8f1afd3b37	Cosmetics: apply misc style fixes. Originally committed as revision 25219 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Niedermayer	6ed040408b	Move AVOptions from libavcodec to libavutil Originally committed as revision 25210 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	e44c01563f	Deprecate av_opt_show() in favor of a new function av_opt_show2(), which allows to specify only a subset of all the options to show. Originally committed as revision 25166 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	0b99215c0e	Move eval.c and eval.h from libavcodec to libavutil, and make the eval API public. Originally committed as revision 23485 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9ace13b416	Make ff_parse_expr() and ff_parse_and_eval_expr() return an int containing an error code. Allow these functions to convey the reason of the failure to the calling function, failure which is not always due to a parsing error but it may depend for example on a memory problem. Also fix several potential memleaks. Originally committed as revision 23402 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
