From 7e83e1c511baf0d02f3af75b6180d6af4d50aa99 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Sun, 22 May 2011 12:52:50 +0200 Subject: 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. --- libavutil/opt.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'libavutil/opt.c') diff --git a/libavutil/opt.c b/libavutil/opt.c index 7775bb2af3..55bb6d24f0 100644 --- a/libavutil/opt.c +++ b/libavutil/opt.c @@ -29,6 +29,7 @@ #include "avstring.h" #include "opt.h" #include "eval.h" +#include "dict.h" //FIXME order them and do a bin search const AVOption *av_find_opt(void *v, const char *name, const char *unit, int mask, int flags) @@ -538,6 +539,27 @@ void av_opt_free(void *obj) av_freep((uint8_t *)obj + o->offset); } +int av_opt_set_dict(void *obj, AVDictionary **options) +{ + AVDictionaryEntry *t = NULL; + AVDictionary *tmp = NULL; + int ret = 0; + + while ((t = av_dict_get(*options, "", t, AV_DICT_IGNORE_SUFFIX))) { + ret = av_set_string3(obj, t->key, t->value, 1, NULL); + if (ret == AVERROR_OPTION_NOT_FOUND) + av_dict_set(&tmp, t->key, t->value, 0); + else if (ret < 0) { + av_log(obj, AV_LOG_ERROR, "Error setting option %s to value %s.\n", t->key, t->value); + break; + } + ret = 0; + } + av_dict_free(options); + *options = tmp; + return ret; +} + #ifdef TEST #undef printf -- cgit v1.2.3
