Problem with various bt878A cards
Posted: Fri Apr 01, 2016 8:37 am
Hi All,
I've got last week three different BT878A based CCTV cards, and decided to build a dvr, but I can't get them worked.
the cards:
Geovision GV650 (I've found card=157,158 parameter)
Geovision GV250v2
and a noname (auto detected card=105)
The 2 geovision cards are auto detected generic card=0
What I've already tried:
Firstly I was trying to get work the cards googling keywords bttv, linux, "Card's_name", PCI VEN identifier (eg: 109e:036e), and tried to
modprobe bttv card=x with random card IDs I've found. But without success.
Then i wrote a shell-script incrementing value of i 1 to 167, removes bttv related modules, inserts bttv module with card=$i parameter and grabs an image with fswebcam from Composite0 input. The images are created, but all black with a timestamp at the bottom.
The cards were working before. I'm trying as root, so I have right for the /dev/video* devices
Should I apply any other bttv parameter(s) (for example type=x) to get these cards working?
What other data should I supply for anybody could help me?
Has anybody experience with any of these cards on linux?
Is there any other way to find how can I make them working?
Thanks a lot
Istvan
