Hauppauge 2200 on new Arch install with MythTV 0.26

I've done a fresh Arch x86_64 install on my HTPC. I previously had Arch on it, and I'm still running that temporarily until the new install works correctly (I've actually got 3 operating systems on it just to compare - old Arch, fresh Arch install and Slackware 14). Both Slackware and fresh Arch install are being installed at the same time. Both running Xfce, XBMC 11.0, MythTV 0.26.

I decided to start fresh with Arch when I changed entirely to systemd. I installed XBMC fine, but my Hauppauge HVR 2200 tuner is causing all sorts of problems with a fresh Arch install and MythTV 0.26. I followed the same procedure I had previously done with Arch and Slackware, found here. I used the "making it work easily" piece. I currently having it working in Slackware and the old Arch install, but the new install gives a journalctl MythTV message of

DVBChan(1:/dev/dvb/adapter0/frontend0): Failed to open DVB frontend device due to fatal error or too many attempts.

which is really strange, because I can go into mythtv-setup, delete the old tuners and create new ones, and then scan for channels correctly. However, I cannot then go through the frontend and Watch TV. The message reports "All tuners are currently busy". The Information Centre -> System Status -> Tuner Status states "Tuner 1 has an error". Same for Tuners 2,3 and 4.

At this stage if I restart the backend, the Tuner status appears normal, but I still cannot record anything or watch Live TV. Attempting to watch Live TV just shows a very quick black screen with "Please Wait" in the middle, and then returns to the Main Menu. I've checked permissions on the recordings folder, which is in fact the the same for all three OS, just mounted in the correct place. Mythtv user has same uid and gid for all 3 OS.

The second problem is that I have used /usr/share/mythtv/mythconverg_restore.pl to import my database from my old Arch install. All of the listings have appeared in the frontend, but every single one of them reports "Recording Unavailable. The file for this recording can not be found". This is strange because I was able to successfully import the old database into my Slackware MythTV 0.26.

Hoping to resolve TV Tuner issue first, but any input welcomed.

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

I made an addition to the [Unit] section of /etc/systemd/system/mythbackend.service:

[Unit]
Description=MythTV Backend
After=network.target mysqld.service
Wants=dev-dvb-adapter0-frontend0.device
After=dev-dvb-adapter0-frontend0.device
Wants=dev-dvb-adapter1-frontend0.device
After=dev-dvb-adapter1-frontend0.device
Wants=dev-dvb-adapter2-frontend0.device
After=dev-dvb-adapter2-frontend0.device

If mythbackend is starting before the adapters finish initializing (particularly when firmware is still loading) then it will think they are unusable. When you run mythtv-setup, mythbackend isn't running and the adapters have long since finished initializing.

Otherwise, you may need to repair the database: mysqlcheck -Ap --auto-repair <mysql password>. Your user must also be part of the proper group to access the /dev/dvb/adapter* devices.

As for the recordings being unavailable, you probably don't have storage groups setup, or access to them. I use SYMLINK udev rules to create persistent devices for the storage partitions. Then fstab rules to mount those to directories configured as storage groups in mythtv-setup, and the permissions on the directories to allow them to be read.

The old storage groups should be configured from your database backup, but you probably don't have them either mounted or readable.

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

Hi fphillips,
I tried adding the extra lines to /usr/lib/systemd/system/mythbackend.service which was effective in making the backend wait for the tuners, but still no LiveTV or ability to record after rebooting. I do get my two tuners appear in /dev/dvb/adapter0 and /dev/dvb/adapter1, and both my user and mythtv user are members of video group.

Strangely, without those lines added the backend is started by user 'mythtv', even though in /etc/conf.d/mythbackend I have MBE_USER='root'. I have noticed though that the default in /etc/rc.d/mythbackend is to have MBE_USER='mythtv', shouldn't the conf.d file take precedence?

The mysqlcheck command output that everything was OK. I also have the exact same Storage Groups setup as my previous install, and have an fstab entry to mount the recordings disk in the same location for all my installs. They are definitely readable, can play them fine in VLC.

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

The files in /etc/conf.d and /etc/rc.d are for sysvinit, and don't apply when using systemd. You configure with /etc/systemd/system/mythbackend.service which overrides the file in /usr/lib/. I would check the mythbackend log in /var/log/mythtv/ to see why its not recording. You can change the loglevel and verbosity in the service file if necessary (see mythbackend --help).

What messages are there in dmesg about firmware?

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

While trying to change the loglevel I issued the following command (as root)

# systemctl stop mythbackend.service

and then as my user (david, without root priveleges) I issued in one terminal

$ mythbackend --loglevel debug

and in another terminal I issued

$ mythfrontend

I then checked and both mythbackend and mythlogserver are running as 'david'. Unbelievably to me, I was able to find all my old recordings, play them, and also watch LiveTV!

But when the backend is running as 'root' or 'mythtv', I still cannot. I'm completely stumped! Does this mean that during installation I was logged in as 'david' and was meant to be logged in as 'mythtv'?

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

At the end of the mythtv backend log you have a permission error for your LiveTV storage group. You should chown -R user:group /home/david/MythTV/Recordings/LiveTV.

What are the permissions on that directory and what groups does mythtv belong to?

Shouldn't I be able to logout of 'david' Xsession and log into 'mythtv' Xsession? At the moment I cannot, and I get a "failed to issue login command" error. Everything seems to be there though.

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

I have made the following changes, and the system works.

$ cat /usr/lib/systemd/system/mythbackend.service 
[Unit]
Description=MythTV Backend
After=network.target mysqld.service
Wants=dev-dvb-adapter0-frontend0.device
After=dev-dvb-adapter0-frontend0.device
Wants=dev-dvb-adapter1-frontend0.device
After=dev-dvb-adapter1-frontend0.device

[Service]
Type=simple
Environment=HOME=/var/lib/mythtv
User=david
ExecStart=/usr/bin/mythbackend --logpath /var/log/mythtv
ExecStop=/usr/bin/mythshutdown --setscheduledwakeup
#ExecStop=/usr/bin/mythshutdown --shutdown

[Install]
WantedBy=multi-user.target

Simply by using 'david' as the user and telling Mythbackend to wait for the adapters, I have access to all my old recordings, and can make new recordings fine. If I change the user to 'mythtv' it fails. So I recently updated my system and a mythtv update happened, all I needed to do was correct the file /usr/lib/systemd/system/mythbackend.service and I was running fine again.

Thanks for all your help throughout this, wouldn't have discovered how to get it working without the help.

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

I'm going to keep tinkering and try to get it working for a dedicated 'mythtv' user too. I think that when I installed MythTV the user was created for me, rather than me doing it. Home directory was created in /var/lib but I also have a /home/mythtv folder. Wondering if this has broken some paths in MythTV?

$ cat /etc/passwd | grep mythtv
mythtv:x:1001:1001::/var/lib/mythtv:/bin/bash

$ ls -al /home/ | grep mythtv
drwxr-xr-x  4 mythtv users  4096 Jan 14 09:09 mythtv

$ ls -al /var/lib/ | grep mythtv
drwxr-xr-x  4 root  root   4096 Jan 15 09:59 mythtv

Also, shouldn't the permissions/ownership on /var/lib/mythtv be different? Because if I change to user 'mythtv' on the command line and change directory to the home directory /var/lib/mythtv I cannot create any new files or folders within it.

Re: Hauppauge 2200 on new Arch install with MythTV 0.26

Copy the mythbackend.service and make changes to /etc/systemd/system/mythbackend.service which overrides the file in /usr/lib/. This way upgrades won't overwrite it. You can then restore the stock file in /usr/lib/ and see the config changes you make with systemd-delta.

I can't pinpoint exactly how the mythtv user is failing for you, but start with a chown -R mythtv:users /var/lib/mythtv, or if you prefer /home/mythtv, change it in /etc/passwd and the Environment=HOME line.

Once you have made your changes, do systemctl --system daemon-reload and systemctl restart mythbackend, or just reboot.
