Hello,
> does anybody have the TRUST 814 PCI [4-inputs x 1-chip] card working
> with the bttv driver?
looking at the pictures on the Trust website this card seems to be
identical to the "Grandtec X-Guard" card i bought some weeks ago:
http://io.ram.rwth-aachen.de/xguard.jpg
This card uses two dual-4-input-video multiplexers that are controlled
by the vision878's gpio pins. That way up to 16 inputs are connected to
the 4 inputs of the vison878. I have sent the modifications to the bttv
driver necessary to make the card work to Gerd, but got no response yet.
However, the modifications are quite simple. I have attached the patch
for bttv-0.7.105. It works fine for me. Please let me know if it works
for you card, too!
Tschuess
Markus
