[FFmpeg-devel] [PATCH] avformat/hls, dashdec: Don't use AV_OPT_FLAG_* in av_dict_set()

[Andreas Rheinhardt]

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.)
