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.
