Hi,
On my box, /dev/vbi0 is as follows:
crw-rw---- 1 mythtv video 81, 224 Jun 21 20:29 /dev/vbi0
I have no /dev/vbi{4,8} - should I?
I also get the "CC/TXT disabled" when hitting 't' on the keyboard,
although the device is readable to myth and the frontend is started up
from the mythtv user.
The backend is started from root.
Cheers,
-Morten

I'm not 100% sure this is the right list, but I can't
get any CC/Teletext in MythTV from the ivtv drivers.
In /dev, I have vbi0..vbi4 and vbi8, and a link
vbi->vbi0. Normally when I boot they all have 600
permissions. My startup scripts chmod them to 666
(twice!), once before starting mythbackend and once
after (i.e. before mythfrontend). While it boots,
when I watch the perms, and vbi0, vbi4, and vbi8
invariably go 600->666->600->666->600, as if something
keeps setting them back to owner-only (root) perms
after I change them.
Whenever I try to start teletext in Myth (0.18.1), I
get the message "CC/TXT disabled", which makes sense I
suppose since the mythtv user isn't even allowed to
read from the devices! I've also added mythtv to the
"video" group (which is the group ownership for vbi*)
but still no luck (notice group perms also go back to
0).
I get these entries in /var/log/messages:
Jun 21 08:17:59 capricorn kernel: ivtv:
ivtv_enc_thread: pid = 4397, itv = 0xf8e
2d720
Jun 21 08:17:59 capricorn kernel: ivtv:
ivtv_enc_vbi_thread: pid = 4398, itv = 0
xf8e2d720
Jun 21 08:17:59 capricorn kernel: ivtv:
ivtv_dec_thread: pid = 4399, itv = 0xf8e
2d720
Jun 21 08:17:59 capricorn kernel: ivtv:
ivtv_dec_vbi_thread: pid = 4400, itv = 0
xf8e2d720
And these when I start recording something in Myth:
Jun 21 08:18:10 capricorn kernel: ivtv: Setup VBI API
header 0x0000bd0d pkts 1 b
uffs 4 ln 24 sz 1456
Jun 21 08:18:10 capricorn kernel: ivtv: Setup VBI
start 0x0018ea04 frames 4 fpi
1 lines 0x000000f1
but nothing in /var/log/mythfrontend.log that I can
see.
Any help is greatly appreciated! I've googled around
for this and I can't find how to address this.
Searching the wiki proved unsuccessful.
Thanks!
