I was too fast at replying again.

Yes, but I don't consider requiring (to refer to a recent thread)
"obscure incantations" to use lavc any good either.
So that leaves ignoring. Do you have an idea how to ignore thread_count
(and use the proper slice flags) when hardware-accelerated
decoding is used, and in a way that works with selecting just the
PIX_FMT via get_format and is not too messy?
I am not particularly interested in learning the details of mpegvideo.c
before I can decide which way might be acceptable.

And to clarify: I meant that I do not know why they are user-settable in the first
