Device not showing in Synology docker

[irrits]

Hi,

I was hoping to get a little bit of help with the launch options for my NextPVR docker on my Synology DS918+? Here's the code:

sudo docker run -d --name nextpvr --restart unless-stopped \
--volume /volume1/docker/nextpvr/config:/config  \
--volume /volume1/docker/nextpvr/video:/recordings \
--volume /volume1/docker/nextpvr/buffer:/buffer \
--publish 8866:8866 \
--env TZ='Australia/Melbourne' \
--publish 16891:16891/udp \
--device /dev/dri:/dev/dri  \
nextpvr/nextpvr_amd64table


It launches fine but I can't see my device (a MyGica DVB-T USB tuner). If I use Video Station I can see the tuner and can see program guides and tv shows.

Is it the --device line that's wrong? I can't find the right path in the synology through the CLI.

Any help would be most appreciated.

The /dev/dri: is mapped is for h/w transcoding. You would need to map /dev/dvb and see if that works.

Thank you, Martin.

I tried changing the line to

--device /dev/dvb:/dev/dvb

And got this error:

docker: Error response from daemon: linux runtime spec devices: error gathering device information while adding custom device "/dev/dvb": not a device node.

That directory is empty, but the tuner still works in VideoStation. Do I need to find the path for the tuner?

Do I need to find the path for the tuner?

I'd be suprised if it's not /dev/dvb. Just doing a quick google, I can see others indicating their tuners were listed in /dev/dvb on their synology devices.

Thank you, turns out that as you said, it was in /dev/dvb as adapter0 but only when Video Station was actually using it (otherwise /dev/dvb was empty). Seems like I could only launch the docker image using that device mapping if Video Station was actively using the tuner.

Cheers
