Folks, the problem was banal but hard to find. The movie I tried to
encode started with broken frames. That's why mcdeint failed to get
reference fields. I think it would be a good idea to implement an
option that checks for broken frames and/or skips them. That would
have solved my problem from scratch. Anyway, thanks for your help!
