Yes, I saw it on the mail list and I think it is a good idea :-)

|

Actually, this was done by Bertrik Sikken (bertrik@zonnet.nl), Michel
|
||||
Xhaard (mxhaard@magic.fr) and me. But Bertrik was the one who found out
|
||||
how to decode the lines :-)

|
||||
For me it's no problem to release it with LGPL. Maybe you have to ask
|
||||
the other one's also.

O leuk, zoiets is naar mijn idee precies wat er nodig is voor webcam

support onder linux. Ik ben een jaar of 3 geleden heel actief geweest
|

met een aantal webcams, maar doe er tegenwoordig helemaal niets meer

aan.
