Bug 141232 – ivtv-0.7.0 ebuild requires removed config flag from kernel 2.6.17

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Alexander Hsia 2006-07-20 20:45:17 UTC]

Emerging ivtv-0.7 gives an error saying compatible flag in kernel is not set.

VIDEO_SAA711X

This flag doesn't exist in gentoo-2.6.17-r3

[Comment 1 Jakub Moc (RETIRED) 2006-07-21 00:15:29 UTC]

# zgrep VIDEO_SAA711X /proc/config.gz

On my box:
# zgrep VIDEO_SAA711X /proc/config.gz 
returns nothing

# zgrep VIDEO_SAA7127 /proc/config.gz 
CONFIG_VIDEO_SAA7127=m

Smells like a
# cp /usr/src/linux-2.6.16.*/.config /usr/src/linux && cd /usr/src/linux && make && make modules install
... no ?
I myself do not have this flag either, same as Alexander, except that my machine is an AMD64 one.

The real problem here is you need to:

  Enable Video For Linux API 1 (DEPRECATED)
    VIDEO_V4L1

In order for the

  Phillips SAA7113/4/5 video decoders (OBSOLETED) (NEW)
    VIDEO_SAA711X

to appear in the Device Drivers -> Multimedia Devices -> Video Capture Adapters ->  Encoders and Decoders menu.

[Comment 6 Jakub Moc (RETIRED) 2006-07-22 13:43:27 UTC]

(In reply to comment #5)

So enable it - what's the problem? Still don't get it.

[Comment 7 Doug Goldstein (RETIRED) 2006-07-22 15:15:31 UTC]

Added a check since obviously the linux-mod.eclass doesn't enforce dependancies.

Thank you Jakub for the quick response, and sorry for reporting the duplicate bug. Could you explain to me then why V4L1 is required for ivtv-0.7.0? I compiled it with V4L2 (and without V4L1 compatibility) and it works just fine.

V4L1 is deprecated and ivtv-0.7.0 is for 2.6.17 (i.e. modern) kernels anyways. I'm having a Hauppauge PVR500, maybe some other hardware models need the V4L1 somehow? Or is there another reason?

I already did - Bug 143374, Comment #2. Also, read Comment #5 in this bug.

[Comment 11 Sybren Harmsma 2006-08-09 14:21:40 UTC]

OK, then let me rephrase: why not do away with both VIDEO_V4L1 (DEPRECATED) and VIDEO_SAA711X (OBSOLETED). What about letting people try out the ebuild I submitted in bug 143374 ?

[Comment 12 Doug Goldstein (RETIRED) 2006-08-09 16:13:28 UTC]

Because the ebuild submitted in that bug is wrong. It is required for certain cards. Not all cards. Some cards used the older chip. The driver for that chip is not ported over yet. It is required. Read the ivtv documentation.
