[FFmpeg-user] DeckLink Duo 2 duplex_mode doesn't work

[Rik Roukens]

Thanks for your response Mustafa, the cards are definitely capable of it,
as I've done it in windows.
perhaps you need to set the duplex mode on 1 and 2, which then opens up sdi
3&4 to be individually programmed.
I'll give that a go tomorrow, it sounds a bit strange, as it would mean
that you always have to run a command on input 1 and 2 before you are
'allowed' to use sdi input 3 and 4.

I'll report back tomorrow.
