Hello :)
Thnx for the reply !
Well, I do not have the cables ... it's a laptop card, orginally for a Dell,
I am doing my tests on an Acer,
The Video0 dev , composite/s-video is showing an analog signal, i guess a
"noise" picture because not hooked-up,
but bottom half is sometimes green .
Analog scanning/reception = NULL , I might have to check again the antenna
connexion,
For the Mpeg, negative, it's a 9013 chip, I still have to discecte the 9015
driver and pull-out
the 9013 spcific data , iguess .
What I need the most, Is a big picture of the V4L API , like an organigram of
what is where ( initialising this or that,
handeling setups - and controls)
I code, but going thru others Code, is always like playing Maze ... :)
especially an API in a whole System Package...
But I am searching on my side :)
I there a dummy /test driver for PCIe cards I can study ?
Best regards
Rémi.
