Anton Khirnov	c3ecd968f0	AVOptions: add flags for read/read-only options	11 years ago
Anton Khirnov	0b357a8095	AVOptions: do not range check flag options. It does not make sense in the vast majority of use cases, no currently defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything nontrivial, and many of those get it wrong (the "correct" range is INT_MIN to INT_MAX so that the builtin constant "all" works).	11 years ago
Martin Storsjö	c7e921a54f	avopt: Check whether the object actually has got an AVClass AVIOContext has got an av_class member that only gets set if opening the context using avio_open2, but not if allocating a custom IO context. A caller that wants to read AVOptions from an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may not know if the AVIOContext actually has got a class set or not.

Anton Khirnov	bcc9432898	opt: check the return values of av_get_token for ENOMEM.	12 years ago
Anton Khirnov	cf53704c55	AVOptions: make av_set_options_string() forward options to child objects	12 years ago
Anton Khirnov	4d67ff8e8e	AVOptions: fix using named constants with child contexts. The named constant needs to be searched for in the same object on which the option is set, i.e. target_obj.	12 years ago
Anton Khirnov	9676b9a2cd	AVOption: remove an unused function parameter.	12 years ago
Diego Biurrun	bcb8d9eb8f	Drop unnecessary 'l' length modifier when printfing double values. %f denotes a double argument and 'l' does nothing in this case according to the C spec.	12 years ago
Justin Ruggles	d02202e08a	opt: avoid segfault in av_opt_next() if the class does not have an option list CC: libav-stable@libav.org	12 years ago
Justin Ruggles	9d5c62ba5b	lavu/opt: do not filter out the initial sign character except for flags This allows parsing of special-case negative numbers like decibels.	12 years ago
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Anton Khirnov	c692957c4e	lavu: remove disabled avoptions cruft	12 years ago
Martin Storsjö	21bc440384	avopt: Explicitly store rational option defaults in .dbl Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	e6153f173a	avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	d58dd4b5b5	avopt: Store defaults for AV_OPT_TYPE_FLAGS in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	124134e424	avopt: Store defaults for AV_OPT_TYPE_CONST in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	4d7adec8bd	AVOptions: store defaults for INT64 options in int64 union member. Double does not have enough precision to represent all int64 numbers exactly.	13 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	3893feeccd	opt/eval: Include mathematics.h for NAN/INFINITY These files use NAN/INFINITY but didn't include mathematics.h to get the fallback definitions if the system lacks the macros. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	0426c69310	AVOptions: fix the value printed in out of range error message.	13 years ago
Samuel Pitoiset	154486f9ad	opt: Add av_opt_set_bin() Introduce a new function to set binary data through AVOption, avoiding having to convert the binary data to a string inbetween. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	e1e22851c1	AVOptions: don't return an invalid option when option list is empty	13 years ago
Martin Storsjö	299234a0a9	avoptions: Fix av_opt_flag_is_set With the changes in `3b3ea34655`, "Remove all uses of deprecated AVOptions API", av_opt_flag_is_set was broken, since it now uses av_opt_find, which doesn't return named constants unless a unit to look for the constant in is given. This broke enabling LATM encapsulated AAC output in RTP. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	85afbb1d00	AVOptions: don't segfault on NULL parameter in av_set_options_string()	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
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().	14 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
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
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
