mythtv Hauppauge HVR-1600 Problem with capture cards

[jerkface]

Binary package hint: mythtv

1) 10.04 Alpha

2) mythtv-backend:
  Installed: 0.23.0~trunk23567-0ubuntu3

3) cx18 module is loading without errors, and I can record video by $cat /dev/video0 > test.mpg, so mythtv should not be reporting any errors when it starts, or when a frontend tries to start watching live tv, and it should record scheduled recordings on the cards 2 available inputs.

4) mythtv system status log entries are filling up with:

Problem with capture card
Card 1failed init

Trying to watch live tv gives this error message:

Error: MythTV is using all inputs, but there are no active recordings?

Also, the backend is not recording any scheduled recordings.

5) Additional information: I rebuilt the module and reinstalled the firmware for it following the instructions here:

http://www.mythtv.org/wiki/Hauppauge_HVR-1600

but mythtv still is reporting the same errors.

[Thomas Templin (coastgnu)]

Same behaviour here with an Haupauge PVR-150 (ivtv)

Error message is the same as above "Fehler: Alle Eingänge sind belegt, aber es gibt keine laufenden Aufnahmen?"

Also, the backend is not recording any scheduled recordings.

Adding a new schedule has no effect.

Viewing old recordings works.

I've committed an additional patch to mythtv_0.23.0~trunk23567-0ubuntu4. Once that lands on the archive, can one of you please comment here whether it is working properly after restarting the backend?

Thanks,

  * debian/control:
    - Build-depends on libxrandr-dev for xrandr support.
    - Restore Build-depends on libfftw3-dev (not really a top secret option)
  * debian/source_mythtv.py:
    - Don't use bool, apport doesn't like them.
  * debian/patches/36_setgroups_too:
    - Run setgroups() before setgid/setuid (LP: #524822)

  [ Andres Mejia ]
  * Refresh all patches. Use '-p ab' format with no index or timestamps.
  * Add comment for each patch.
  * Update debian/control file for minor cosmetic changes.
  * Don't depend on transcode for mythtv-transcode-utils since it's not needed.
  * Don't Build-Depends-Conflicts on libmyth-dev.

Installed 0.23.0~trunk23567-0ubuntu4 this afternoon. Still seeing the same thing.

[Mario Limonciello (superm1)]

I just upgraded a system from hardy->lucid and tested a PVR500 without any problems w/ that new mythtv build personally.

@jerkface:

So, I am suspecting there is something else broken here with your config other than the not properly setting groups for mythbackend.
Can you please show the output of the following:
# groups mythtv
# ps aux | grep ^mythtv
# cat /etc/default/mythtv-backend
# cat /etc/init/mythtv-backend.conf

Also please attach your backend log.

@Thomas Templin:

Can you please verify with the new build that things are fine for you too?

[jerkface (jerk-deactivatedaccount)]

Sorry, can't post the logs. Wiped the system and reinstalled. Now mythtv-backend wont install due to missing dependencies.

Accept this solution? [Y/n/q/?]

[Mario Limonciello (superm1)]

Make sure you have both universe and multiverse enabled. I also recommend you avoid using aptitude because it has a tendency to install more dependencies than are necessary.

[jerkface (jerk-deactivatedaccount)]

Yeah, both universe and multiverse were enabled.

[jerkface (jerk-deactivatedaccount)]

Scratch that, I chose a different repository and now it is installing. Will update tonight or tomorrow whether the tuners are working now or not.

[jerkface (jerk-deactivatedaccount)]

It's a group issue. /dev/dvb was owned by root:video. I changed the group to mythtv and am able to use the digital tuner. I wasn't able to open the analog tuner to add it.

# groups mythtv
mythtv : mythtv dialout cdrom audio video

end script

[jerkface (jerk-deactivatedaccount)]

Ok, so after chgrp'ing /dev/video* from video to mythtv, I could add the analog tuner, but in the mythtv-setup screen under the ivtv section, it said 'failed to open' until I manually typed in /dev/video0. Then the screen updated to show it was using the cx18 driver and Tuner1. Not sure why it didn't work with /dev/dvb/* and /dev/video* in the video group, since mythtv was a member of the video group, but my system works again, so I am happy.

[Mario Limonciello (superm1)]

OK: I've reproduced this and have updated the patch to what I believe will fix it. It will be present in the next upload to the archive.
