| |
Hello,
I have a framegrabber to work with linux (2.4.18). It's a BT878 device and I have a lot of questions :(
a) It does not use the muxsel-bits in BT848_IFORM but some bits in BT848_GPIO_DATA to select video-input---so seems to be a quite unusual device.
Should I make switch(btv->type) statments in bt848_muxsel?
b) several registers have to be initialised to other values then usual, to make the card work.
At the moment I'm doing this in bt848_muxsel, but I would like to move to a place where it is not executed every time I switch input Is init_bt848 the right place?
(The framegrabber should generate sync-signals and provide them to the cameras allowing to switch between cameras in 40ms, so initializing the chips every time would not work)
c) It does not identify with PCI_SUBSYSTEM_ID/PCI_SUBSYSTEM_VENDOR_ID (gives 0xffff). Any other way to autodetect it?
d) Who is the bttv-maintainer?!
MfG bmg
