dvr0: unable to open

Added by Phill Lavender over 10 years ago

TV cards where working fine then just stopped. I rebooted and ever since haven't been able to view channels on them. Only thing i can see in the logs is as follows:

[INFO]:dvb: Found adapter /dev/dvb/adapter0 (FireDTV S/CI) via PCI
[INFO]:dvb: Found adapter /dev/dvb/adapter1 (Conexant CX22702 DVB-T) via PCI
[ALERT]:dvb: /dev/dvb/adapter1/dvr0: unable to open dvr
[INFO]:dvb: Found adapter /dev/dvb/adapter2 (Conexant CX22702 DVB-T) via PCI
[ALERT]:dvb: /dev/dvb/adapter2/dvr0: unable to open dvr

Later logs show the tuner is in use and tuning though:

[DEBUG]:dvb: "/dev/dvb/adapter1" initial scan completed for "SFN: 858,000 kHz"
[DEBUG]:dvb: "/dev/dvb/adapter1" tuning to "RGE MADRID: 770,000 kHz" (Initial autoscan)
[DEBUG]:dvb: "/dev/dvb/adapter1" initial scan completed for "RGE MADRID: 770,000 kHz"
[DEBUG]:dvb: "/dev/dvb/adapter1" tuning to "698,000 kHz" (Initial autoscan)

[DEBUG]:dvb: "/dev/dvb/adapter1" initial scan completed for "Teledifusion Madrid: 618,000 kHz"
[DEBUG]:dvb: "/dev/dvb/adapter1" tuning to "Teledifusion Madrid: 570,000 kHz" (Initial autoscan)

Anyone any ideas ?

No info in kernel log or dmesg?

Fixed. I removed all but one tv card reset group permissions for video audio.
I guess its a udev and permissions issue, but working now.

Bte the bug fix to skip over extended rtp headers is missing 4bytes. See my update.
Thx
Phill.
