Newbie : webcam return black screen

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]




Hello, list.

As I suspected my BT878 return black screen, I used a Miro compatible card to retry the test. The bttv2 modules boot OK and return the correct card type.

Upon execution of webcam program came with xawtv, the messages looks OK.

BUT, I still get a black screen. Please give me some advice.
