Andreas Rheinhardt 187cd27832 avutil/dict: Error out in case of key == NULL ... Up until now, using NULL as key in av_dict_get() on a non-empty AVDictionary would crash; using NULL as key in av_dict_set() would also crash for a non-empty AVDictionary unless AV_DICT_MULTIKEY was set; in case the dictionary was initially empty or AV_DICT_MULTIKEY was set, it was even possible for av_dict_set() to succeed when adding a NULL key, namely when one uses a value != NULL and the AV_DICT_DONT_STRDUP_VAL flag. Using av_dict_get() on such an AVDictionary will usually lead to crashes, though. Fix this by actually checking for key in both functions; error out if they are NULL. While just at it, also stop relying on av_strdup(NULL) to return NULL in av_dict_set(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>		2022-09-19 23:39:58 +02:00
