Passthrough usb tuner to container

[ruffpl]

I am trying to get usb tuner to Ubuntu container (Container number 212, device 212, Bus 003 Device 002: ID 2040:8268 Hauppauge soloHD). This is what I get:

lsusb

Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 2040:8268 Hauppauge soloHD
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0b05:1872 ASUSTek Computer, Inc. AURA LED Controller
Bus 001 Device 002: ID 0b05:185c ASUSTek Computer, Inc. Bluetooth Radio
Bus 001 Device 005: ID 04ca:007d Lite-On Technology Corp. USB wired keyboard
Bus 001 Device 004: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

ls -l /dev/dvb/adapter0

crw-rw---- 1 root video 212, 1 Jan 19 15:38 demux0
crw-rw---- 1 root video 212, 2 Jan 19 15:38 dvr0
crw-rw---- 1 root video 212, 0 Jan 19 15:38 frontend0
crw-rw---- 1 root video 212, 3 Jan 19 15:38 net0

Then I add to container cfg. file

lxc.cgroup2.devices.allow: c 212:* rwm
lxc.mount.entry: /dev/dvb dev/dvb none bind,optional,create=dir

What else I should do? I got tvheadend installed, got tuner firmware but I think it is not passing it to container.

I put the firmware on the host and let the host load all the necessary drivers. Then I passthrough the /dev/dvb directory to the container like you did:
lxc.cgroup2.devices.allow: c 212:* rwm lxc.mount.entry: /dev/dvb dev/dvb none bind,create=dir 0 0
I also map the video group of the container (44) to the video group of the host (also 44), so access is allowed:
lxc.idmap: u 0 100000 65535 lxc.idmap: g 0 100000 44 lxc.idmap: g 44 44 1 lxc.idmap: g 45 100045 65490
MythTV backend can then find the USB tuner (Hauppauge WinTV-dualHD) via /dev/dvb.

Hi,
what's the output of lsusb run inside the container?

 

[ruffpl]

Yes!!! I made it after whole week of failed attempts. I was searching internet, youtube tvheadend forum, ubuntu, reddit, etc and found a solution just in here.

I added the line in container .cfg file:

chown 100000:100044 -R /dev/dvb

and finally my tuner showed up just before I wanted to give up....

Now. I added 5 muxes and 3 of them found channels (the rest I will take care later). I would like to record videos on ssd that I had connected in proxmox as /mnt/pve/SSD

I added the line

mp0: /mnt/pve/SSD/,mp=/mnt/TVrecord

and I can access to it by

ls /mnt/TVrecord

but when I add the storage path to recordings (Tvheadend Ubuntu container) I get error that file was not created ( original path is /home/hts). Am I doing something wrong? Can I set up home/hts folder to my /mnt/pve/SSD (it records without problem in original location)

 

[leesteken]

mp0: /mnt/pve/SSD/,mp=/mnt/TVrecord

and I can access to it by

ls /mnt/TVrecord

but when I add the storage path to recordings (Tvheadend Ubuntu container) I get error that file was not created ( original path is /home/hts). Am I doing something wrong? Can I set up home/hts folder to my /mnt/pve/SSD (it records without problem in original location)

Sounds like a permission issue. Check with ls -al /mnt/TVrecord. Maybe chown 100000:100044 on the directory on the host might help? What user is Tvheadend using inside the container? Use that for the chown command to allow write access.

For something complicated like that, why not pass the entire host usb port?
That way you don't have to mess with multiple individual things to pass through.

Maybe I am doing something wrong. I made it second time with unchecked unprivileged container and I had edit features mount=nfs,cifs
Now I would like to get my Ubuntu Tvheadend container to record videos into folder outside container.

Location of that folder - extra sata ssd drive in Proxmox as SSD Directory, root owner/ On my server as //192.168.1.99/mnt/pve/SSD/TVrecords
Default location of Tvheadend recordings is in 212 container, owner - root, tvheadend, it has admin and root accounts and folder is located in /home/hts. I had also created mnt/TVrecords in container

How can I add TVrecords folder to Tvheadend container so it will record files on bigger disk/ not inside container?

 

[ruffpl]

Made it. I had created container once again, set up as root as a tvheadend main user. On ssd I created new directory by Filezilla with read/write/execute (777) permisssions called TVrecordings (and probably that solved the problem). After that I had edit nano /etc/pve/lxc/212.conf

mp0: /mnt/pve/SSD/TVrecordings,mp=/TVrecordings

In tvheadend I chose /TVrecordings as storage patch and 200gb showed up next to tvheadend clock. Recording works, the file can be saved in the specified folder without any problems. Finally I can use it like I wanted
