V4L Bt878
 
hello.

i have a video capturing card:
Code:
root@eXKoR--su3.00 [/usr/src/linux-2.6.7]>lspci | grep 878
00:0b.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
00:0b.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
while booting kernel 2.6.7 i get:
Code:
Feb 10 16:48:25 eXKoR kernel: Linux video capture interface: v1.00
and this is the only message related to video, that the kernel spits out.

the funny thing is, if i boot my old 2.4.26 kernel i get this:
Code:
Feb  5 08:20:34 eXKoR kernel: Linux video capture interface: v1.00
Feb  5 08:20:34 eXKoR kernel: i2c-core.o: i2c core module version 2.6.1 (20010830)

my current kernel is not compiled with I2C, but Video for Linux is built-in.

my question is, what is the problem with my 2.6.7 kernel, is it I2C??
if so, would it be better to compile it as a module or a built-in??

thnx for ur time.

It looks like everyhting bttv related loades properly... you have a dev entry like '/dev/video0' ?

i didnt have bttv until yesterday when i recompiled my 2.6.7 kernel with I2C and V4L as modules. heh.

now i have bttv modules loaded with videodev :) so hopefully everything should work fine.
and yea i do have /dev/video now :)

currently im struggling to install a video capturing software, which does a bad "./configure" !!!! :)

thnx for ur time
