Bug 135941 – media-video/alevt cannot handle new VBI kernel interface.

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description spiralvoice 2006-06-07 09:50:42 UTC]

this bug is connected to bug #135788

# alevt 100
alevt: v4l2: unable to handle these sampling parameters
alevt: cannot open /dev/v4l/vbi0

using nxtvepg with the patch mentioned here
http://sourceforge.net/forum/forum.php?thread_id=1469517&forum_id=217872

"In file epgvbi/btdrv4linux.c, function BtDriver_OpenVbiBuf() change line  
zvbi_rd.offset = vfmt2.fmt.vbi.offset; 
into 
zvbi_rd.offset = 244; "

I could use gentoo-sources-2.6.16-r9 again, attached patch does
something similar for alevt-1.6.1. Please include in portage.

Created attachment 88610 [details, diff]
patch to let alevt-1.6.1 work again with kernel 2.6.16

[Comment 2 Al Johnson 2006-06-27 16:30:31 UTC]

Won't this patch break things for non-bt8x8 users? It looks to me like the new driver isn't picked up by the conditional at line 529 of vbi.c which looks like it's there to find and set things up for bttv devices, including setting the offset to 244. That's about the limit of my knowledge...

Okay this bug is really old ... still an issue?

Also, 1.6.2 is in tree now.
