/dev/dvb has incorrect permissions

[cgrossde]

/dev/dvb is owned by root and can't be read by tvheadend which resulted in tvheadend not finding my DVB-C card. Changing permissions of /dev/dvb fixed that for me.

docker create \
  --name=tvheadend \
  --net=bridge \
  -v /xxx/config:/config \
  -v /xxx/recordings:/recordings \
  -e PGID=1010 -e PUID=1010  \
  -p 9981:9981 \
  -p 9982:9982 \
  --device=/dev/dvb \
  linuxserver/tvheadend

Fixed it by:

chown -R abc /dev/dvb
pkill tvheadend

Running docker 17.03.0-ce with zfs on Ubuntu 14.04.

Is that the way to go or did I miss something?

generally, most people chown the device on the host to correct user on start up before you run the docker, But what ever way works for you :). Glad you have it working.

We should add it to the readme. I was too unraid minded when I wrote the readme :p

I managed to get dvb cards working by changing permission. But after a reboot, it reverts back to root:root
How do you set shown of dvb on system startup?

[j0nnymoe]

Use a cronjob to run a script to set the permissions before the container starts up

[gurabli]

This is what I did :)
It looks it is working. Now to find out why I can't stream to android tvh client...

Hello,
how do I run a cronjob before the container starts up?
The container is started automatically by docker.

Greetings,

Working udev rule:
cat /etc/udev/rules.d/90-dvbdocker.rules
ATTRS{vendor}=="0x1ade", ATTRS{device}=="0x3038", RUN+="/bin/chown -R ben:users /dev/dvb"

Working udev rule:
cat /etc/udev/rules.d/90-dvbdocker.rules
ATTRS{vendor}=="0x1ade", ATTRS{device}=="0x3038", RUN+="/bin/chown -R ben:users /dev/dvb"

@13 Can that script be copied and pasted into any debian linux udev? What do the vendor and device ids relate to?

I'll open this again. We do have a method to fix the permissions inside the container to make it work. We implemented in plex, and I'll PR here for tvheadend. It works on most distros that rely on the default udev rules, owning /dev/dvb by the video group.

I thought we did add it here, but I guess that was Plex.
