Help with config modes for saa7134

ionet · Post by **ionet** » Thu Feb 25, 2010 6:33 pm

Hi I'm wondering if anyone can tell me wath are the posible attributes that I can give to my card at modprobe.
For example

saa7134 card=72

tuner=
radio=
coring=
full_luma_range=
chroma_agc=
combfilter=
autoload=
triton1=
vsfx=

I just want to know what are those other modes for, and if there are others that I can apply to my card.

This are my card's p specifications.
I have 4 cams, three of them are running in separet frames but the capture of the forth one passes at the back of the other. I hope you understand.
Thank you very much!
I hope you can help me.

Taken from saa7134 driver in gentoo linux 2.6.31-gentoo-r6 kernel.
This is probably the most interesting one.. Can saa7134 chips can do deinterlacing?

Yo thanks for replying.. what's exaclty all this code for.

I really need help with this.

Thanks!!!
