Without seeing source I can not be sure. But I suspect the problem arises
because AVDictionary is not actually defined (other than a declaration) in
the include files included with the dll dist.
If you look in dict.h you'll see only this: "typedef struct AVDictionary
AVDictionary;"

So, somewhere in your include files actually define AVDictionary as such:

//common.h
struct AVDictionary {
    int count;
    AVDictionaryEntry *elems;
};
