av_dict_set() expects a different set of flags, namely the AV_DICT_* flags. Using AV_OPT_FLAG_DECODING_PARAM (or any AV_OPT_FLAG_*) ic av_dict_set() is therefore completely wrong and given that av_dict_set() just doesn't care about whether the string it receives has anything to do with a decoding parameter or not, it should just be removed without replacement. (The numerical value of AV_OPT_FLAG_DECODING_PARAM currently coincides with AV_DICT_IGNORE_SUFFIX. Given that the dictionaries we are dealing with here are always empty (i.e. NULL) before the calls to av_dict_set(), this flag changes nothing. It would be different if it were equal to one of the AV_DICT_DONT_STRDUP_* values.) Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
