Hi,
yesterday i installed a new Kernel (2.4.20 vanilla) Since than i can't use xawtv.
Ok hier is some output:
xawtv
This is xawtv-3.80, running on Linux/i686 (2.4.20)
xinerama 0: 1024x768+1280+0
xinerama 1: 1280x1024+0+0
can't open /dev/v4l/video0: No such file or directory
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/v4l/video0: No such file or directory
v4l2: open /dev/v4l/video0: No such file or directory
v4l: open /dev/v4l/video0: No such file or directory

humm looking to /dev/v4l there is no device in there.

killall -HUP devfsd
And then try xawtv again.
It works for me, but it's obvious that there's a problem in the first place. _________________ IM me at tuxisuau@jabber.7a69ezine.org |

"bash: v4l-conf: command not found"
What package does v4l-conf come from? "emerge -s v4l" finds nothing |

Ok, so v4l-conf doesn't tell me anything new...
Code: |
chi /root # modprobe ibmcam
chi /root # v4l-info
open /dev/video0: No such file or directory
chi /root # ls /dev/v*
/dev/vcs /dev/vcs3 /dev/vcs6 /dev/vcsa1 /dev/vcsa4 /dev/vcsa7
/dev/vcs1 /dev/vcs4 /dev/vcs7 /dev/vcsa2 /dev/vcsa5 /dev/video0
/dev/vcs2 /dev/vcs5 /dev/vcsa /dev/vcsa3 /dev/vcsa6
/dev/vc:
0 12 16 2 23 27 30 34 38 41 45 49 52 56 6 63
1 13 17 20 24 28 31 35 39 42 46 5 53 57 60 7
10 14 18 21 25 29 32 36 4 43 47 50 54 58 61 8
11 15 19 22 26 3 33 37 40 44 48 51 55 59 62 9
/dev/vcc:
0 1 2 3 4 5 6 7 a a1 a2 a3 a4 a5 a6 a7
|
So, I have no /dev/video0 or /dev/v4l/. The kernel was build with v4l support compiled in, and the ibmcam module loads with no problems. This camera worked on my old Gentoo box with kernel 2.4.18, so it is supported by the ibmcam driver.
I'm officially stumped! |

I tried applying the v4l2 patches, didn´t compile.
I think something is mixed up in these newer kernels, I´m currently rebuilding my entire Gentoo, and this time I will install gentoo-sources-2.4.19-r8, because this kernel worked with my card. |

Ok, my problem is not bug, I'm just retarded.
I didn't have the camera plugged in. It works fine now that it is connected to the computer.
DUH!
