Many years ago when the 2.6 kernel was all the rage I had a working
patch to support this card:
https://wiki.zoneminder.com/Digiflower
With the latest Fedora 26 kernel sources with the following patch
applied, the wired input and logical source are scrambled and I don't
know what changed.
Fanout Fanout
Input Camera Source Input Camera Source
1 ..... videoX(??) 9 ..... videoX(??)
2 ..... videoX(4) 10 ..... videoX(12)
3 porch videoX(3) 11 solar videoX(11)
4 ..... videoX(2) 12 ..... videoX(10)
5 ..... videoX(1) 13 ..... videoX(9)
6 ..... videoX(0) 14 ..... videoX(8)
7 ..... videoX(6) 15 south videoX(13)
8 north videoX(5) 16 ..... videoX(14)
Inputs 1 and 9 (Source 7 and 15) simply don't work at all, and they are
all out of order.
What am I not doing, or what changed?
Any help will be much appreciated!
