 Posted: Sun Dec 27, 2009 7:31 pm Post subject: Video Capture Devices missing in menuconfig [SOLVED] |
 |
|
This is kernel 2.6.31 r6.
If I run make menuconfig, and do a search of CX8, it finds VIDEO_CX88_DVB=n
in 2.6.30, this parameter could be found in video capture devices. It is still listed under video capture devices:
Symbol: VIDEO_CX88_DVB [=n] │
│ Prompt: DVB/ATSC Support for cx2388x based TV cards │
│ Defined at drivers/media/video/cx88/Kconfig:46 │
│ Depends on: MEDIA_SUPPORT && VIDEO_CAPTURE_DRIVERS && VIDEO_V4L2 && VIDEO_CX88 && DVB_CORE │
│ Location: │
│ -> Device Drivers │
│ -> Multimedia support (MEDIA_SUPPORT [=m]) │
│ -> Video capture adapters (VIDEO_CAPTURE_DRIVERS [=n]) │
│ -> Conexant 2388x (bt878 successor) support (VIDEO_CX88 [=n]) │
However, there is no Video Capture devices option under Multimedia support. So is menuconfig broken? How do I configure a CX88 device driver? There is still a kernel directory drivers/media/video/cx88.

do you have MEDIA_SUPPORT and VIDEO_V4L2 set in your config ?
what about output from
| Code: | | zgrep -i -e media_support -e video_v4l2 /proc/config.gz |
or if you don't have "/proc/config.gz support in your kernel"
| Code: | | grep -i -e media_support -e video_v4l2 /usr/src/linux/.config |
i remember haveing similar problem but wiht some different options in kernel
i'm not sure but i think "make oldconfig && make prepare" on kernel directory fix that issue

| I think there is a bug in the menuconfig help. CX8* stuff depends on Video for Linux, which according to the help sets VIDEO_DEV. So unless VIDEO_DEV=M, you don't get any video capture devices in menuconfig, Multimedia Support. So VIDEO_DEV is missing from the dependency list. |
