How to Fix HDHomeRun Connect Not Starting MythTV Recordings or Live TV

Summary

This article describes the problem of MythTV not starting scheduled recordings with an HDHomeRun Connect, and how to apply a time delay or a static IP address to fix this problem.

These steps were documented for a MythTV Personal Video Recorder using Mythbuntu 14.04 which uses MythTV 0.27, and a HDHomeRun Connect ATSC network dual tuner. For setup details see Building MythTV PVR with HDHomeRun Network Tuner

Updatge 2023-01-03: From a mythtv-users mailing list discussion entitled "Delaying until HDHR tuners are up before starting mythtv-backend" it appears that an ipv6 connection might establish earlier than an ipv4 one making the hdhomerun discover command report success earlier than it should. The solution was to disable ipv6. See How to disable IPv6 in Ubuntu 14.04?.

Update 2019-01-10: A reader of this article suggested an improved method to deal with this issue. I have not had a chance to test this myself, but decided to add a new proposed solution E so that others might be able to try the new method.
Meanwhile in order to reduce the chance that the HDHomeRun device is not found, we decided to minimize the power cycling on/off by setting this PVR to stay powered on using the MythWelcome Lock Shutdown option.

Problem

Much of the time, the MythTV PVR properly records scheduled recordings and permits watching Live TV. However, occasionally scheduled recordings do not start recording when using an HDHomeRun Connect (dual ATSC tuner). Further sometimes Mythfrontend is unable to tune in TV stations using Live TV.

Moreover, when a scheduled recording is not started, the mythbackend.log (contained in /var/log/mythtv) has the following lines:

----- end mythbackend.log short snippet -----

For a longer snippet see Appendix: mythbackend.log long snippet.

An indication of the problem is shown in the first line Unable to connect to device. At this time both the MythTV PVR and the HDHomeRun Connect are powered on and running on the network.

When this issue occurs, rebooting the HDHomeRun Connect appears to have no effect. However, restarting/rebooting the MythTV Backend will often resolve the issue.

As a temporary workaround we confirmed that scheduled recordings and live TV were working properly and then left the MythTV backend powered on and running. In this situation the scheduled recordings continue to work.

The issue appears to arise only occasionally on MythTV Backend reboot. Because one never knows when a power outage might occur, a better long term solution was needed.

Background Information

The HDHomeRun Connect tuner is connected via Ethernet cat5 cable to a D-Link Gigabit router/switch which is connected via Ethernet cat5 cable to a MythBuntu 14.04 combination backend and frontend server.

The HDHomeRun is configured in the MythTV Backend as follows:

    5.  Input Connections

        For ATSC Over-The-Air Antenna:
              Capture device:  HDHOMERUN : 10416512-0
                Video source:  HD Antenna
                        Name:  HDTuner1
            Starting Channel:  3_1
              Input Priority:  0
              Schedule Order:  1   # Ascending order, increment by capture card max simultaneous recordings
               Live TV Order:  3   # Descending order, to avoid conflicts with scheduled recordings

              Capture device:  HDHOMERUN : 10416512-1
                Video source:  HD Antenna
                        Name:  HDTuner2
            Starting Channel:  3_1
              Input Priority:  0
              Schedule Order:  3
               Live TV Order:  1

Network information:

D-Link Router:  192.168.1.1
   DHCP Range:  192.168.1.100 - 192.168.1.199   # Dynamic IP address range

      mythpvr:  192.168.1.55      # Static IP address
    hdhomerun:  192.168.1.100     # Dynamic IP address

Root Cause

My hypothesis that sometimes the mythbackend fails to connect to the HDHomeRun is:

  • Either networking is not fully functioning when the broadcast name lookup is attempted.
  • Or the problem might be due to delays caused by the time needed to map between an HDHomeRun broadcast name and an IP address.

Proposed Solution A: Add boot delay

NOTE:   Reason Why Time Delay Might Not Work

Originally I thought the network interface eth0 was not operational when the mythbackend attempted to communicate with the HDHomeRun tunner. However further research indicates that the following line in /etc/init/mythbackend.conf will delay startup until a non-loopback network interface, such as eth0, is available.

start on (local-filesystems and net-device-up IFACE!=lo)
More specifically the net-device-up IFACE!=lo portion should wait for an interface other than loopback to also be available before starting mythbackend.

Note that there is still small chance that a time delay might alleviate the situation, especially with the faster loading of services available with a Solid State Drive (SSD).

References:

MythTV.org - Upstart mythbackend Configuration
Upstart Intro, Cookbook and Best Practices - Normal Start

To address the issue, insert a delay in the start up of mythbackend. This is to allow sufficient time for networking to be fully functional before the backend tries to contact the HDHomeRun Connect tuner.

  1. Edit /etc/init/mythtv-backend.conf file.

    sudo leafpad /etc/init/mythtv-backend.conf

    Locate the following lines:

    script
    test -f /etc/default/locale && . /etc/default/locale || true
    LANG=$LANG exec /usr/bin/mythbackend --syslog local7 --user mythtv --daemon
end script

    Insert sleep line between test -f ... and LANG=... lines.

    
script
    test -f /etc/default/locale && . /etc/default/locale || true
    sleep 5   # wait for IP network to start / HDHomeRun Connect
    LANG=$LANG exec /usr/bin/mythbackend --syslog local7 --user mythtv --daemon
end script

    Save file and exit editor.

2016-11-25 Note that the above 5 second time delay was implemented on November 25, 2016.

2016-12-18 The 5 second time delay didn't work.

If this proposed solution does not work, then consider increasing the time delay or trying the next proposed solution.
I am moving onto the next proposed solution.

Proposed Solution B: Set HDHomeRun Static IP Address

To address the issue, assign a static IP address to the HDHomeRun tuner, and configure the MythTV Backend to communicate using the HDHomeRun static IP address. This will remove any time delay involved in mapping from a broadcast name to an IP address.

In this example we will assign the HDHomeRun Connect tuner the following IP address: 192.168.1.61

Note that when choosing a static IP address, be sure that it is outside of the range that is used in the pool for dynamically assigned addresses.

  1. Lookup the current IP address for the HDHomeRun tuner.

    hdhomerun_config discover

    For the rest of these instructions I'll assume we'll use the dynamically assigned IP address: 192.168.1.100

    Example output:

    hdhomerun device 10416512 found at 192.168.1.100

  2. Using the above IP address, assign a static IP address.

    The format of the command is:

    hdhomerun_config <old ip> set /sys/ipaddr "<new ip> <subnet> <gateway>"

    In this example we would have used (It didn't work):

    hdhomerun_config 192.168.1.100 set /sys/ipaddr "192.168.1.61 255.255.255.0 192.168.1.1"

    TIP:   Steps to Revert HDHomeRun Back to Dynamic IP Address

    The format of the command is:

    hdhomerun_config <old ip> set /sys/ipaddr dhcp
    In this example we would use:

    hdhomerun_config 192.168.1.61 set /sys/ipaddr dhcp

    Unfortunately the above command does not work on consumer grade devices like the HDHomeRun Connect.
    See SiliconDust.com: Fixed IP-address?

    Instead, in order to set a non-changing IP address for the HDHomeRun Connect tuner, I had to make a DHCP reservation in my Router.

    The steps for making a DHCP reservation vary from router to router. The basic steps are:

    A. Use a web browser to connect to the router using it's IP address.

    Note that the router is often at 192.168.1.1, but might be at 192.168.1.254.

    B. Login to the router with an administrative account.

    C. Locate the DHCP section in the menu and reserve an IP address for the HDHomeRun's MAC Address.

  3. Configure MythTV Backend to use the HDHomeRun static IP address.

    Start System -> MythTV Backend Setup.

    Go through screens until you reach the menu screen (for example, 1. General).

    Change to use the following settings:

    2. Capture cards

  (Capture Card Setup)
    Card type: HDHomeRun networked tuner
    Available devices:  Manually enter IP address
            Device ID:  192.168.1.100-0
          Description:  hdhomerun4_atsc, firmware: 20150826
           IP Address:  192.168.1.100
                Tuner:  0

    Recording Options
              Signal timeout (ms):  1000
              Tuning timeout (ms):  3000
      Max simultaneous recordings:  2

  (Capture Card Setup)
    Card type: HDHomeRun networked tuner
    Available devices:  Manually enter IP address
            Device ID:  192.168.1.100-1
          Description:  hdhomerun4_atsc, firmware: 20150826
           IP Address:  192.168.1.100
                Tuner:  1

    Recording Options
              Signal timeout (ms):  1000
              Tuning timeout (ms):  3000
      Max simultaneous recordings:  2

  * Note that your HDHomeRun device will have a different number.
    The digit after the dash indicates one of the two tuners.

5.  Input Connections

    For ATSC Over-The-Air Antenna:
          Capture device:  HDHOMERUN : 192.168.1.100-0
            Video source:  HD Antenna
                    Name:  HDTuner1
        Starting Channel:  3_1
          Input Priority:  0
          Schedule Order:  1   # Ascending order, increment by capture card max simultaneous recordings
           Live TV Order:  3   # Descending order, to avoid conflicts with scheduled recordings

          Capture device:  HDHOMERUN : 192.168.1.100-1
            Video source:  HD Antenna
                    Name:  HDTuner2
        Starting Channel:  3_1
          Input Priority:  0
          Schedule Order:  3
           Live TV Order:  1

    Be sure to choose Finish to save the settings.

    Exit out of MythTV Backend Setup using Escape key.

2017-03-03 Implemented this proposed solution.

2017-03-05 The DHCP IP address reservation (essentially a static IP address) did not work.

If this proposed solution does not work, then consider a combination of proposed solutions A and B.
I am moving onto the next proposed solution.

Proposed Solution C: Set HDHomeRun Static IP Address and Add Ping Wait Loop

Set an unchanging IP Address for the HDHomeRun Connect tuner using Proposed Solution B.

Next try delaying mythbackend startup until after we confirm that we can contact the HDHomeRun with a network ping.

In the following wait loop, we try to ping the HDHomeRun up to 60 times, one second apart, before we let mythbackend start.

  1. Edit /etc/init/mythtv-backend.conf file.

    sudo leafpad /etc/init/mythtv-backend.conf

    Locate the following lines:

    script
    test -f /etc/default/locale && . /etc/default/locale || true
    LANG=$LANG exec /usr/bin/mythbackend --syslog local7 --user mythtv --daemon
end script

    Insert the following wait loop between test -f ... and LANG=... lines.

    
script
    test -f /etc/default/locale && . /etc/default/locale || true
    Count=0
    IsAwake=0
    while [ "$IsAwake" == "0" ] && [ "$Count" -lt 60 ]; do
        echo "Waiting for HDHomeRun to appear $Count"
        sleep 1
        let Count=$Count+1
        IsAwake=`ping -q -c1 192.168.1.100 | grep received | cut -f4 -d' '`
    done
    LANG=$LANG exec /usr/bin/mythbackend --syslog local7 --user mythtv --daemon
end script

    Be sure to use the IP Address for your HDHomeRun in the ping line above.

    Save file and exit editor.

2017-03-05 Implemented this proposed solution.

2017-03-11 Unfortunately this solution did not work either. Need to try next proposed solution.

Proposed Solution D: Configure Mythbackend with Upstart Wait Script

Create a script to test for the existence of the HDHomeRun network tuner, and configure mythbackend to use this Upstart pre-start script.

  1. Create /usr/bin/mythtv-findhdhr file for Upstart pre-start script.

    sudo leafpad /usr/bin/mythtv-findhdhr

    Insert the following lines:

    ----- begin mythtv-findhdhr -----

    #!/bin/bash
#
# Check for presence of HDHomeRun network tuner device
#
LOGFILE="/var/log/mythtv/mythtv-findhdhr.log"
TIMELIMIT=20

echo "`date` : Search for HDHR" > $LOGFILE
let "TIMEOUT = `date +%s` + $TIMELIMIT"

while true ; do
   hdhomerun_config discover >> $LOGFILE 2>&1
    if [ "$?" -eq 0 ] ; then
        echo "`date` : HDHR detected - exiting 0" >> $LOGFILE
        exit 0
    fi

    CURTIME=`date +%s`
    if [ $CURTIME -gt $TIMEOUT ] ; then
        echo "`date` : HDHR not detected - exiting 1" >> $LOGFILE
        break
    fi

   sleep 1
done

exit 1

    ----- end mythtv-findhdhr -----

    Save file and exit editor.

  2. Make the script executable.

    sudo chmod 755 /usr/bin/mythtv-findhdhr

  3. Add mythtv-findhdhr to /etc/init/mythtv-backend.conf file.

    sudo leafpad /etc/init/mythtv-backend.conf

    Locate the following lines:

    pre-start script
    [ -x /usr/sbin/mytsqld ] || exit 0

    Insert the line mythtv-findhdhr || true immediately after the pre-start script line as shown below:

    
pre-start script
    mythtv-findhdhr || true
    [ -x /usr/sbin/mysqld ] || exit 0
    for i in `seq 1 30` ; do
       /usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping >/dev/null && exit 0
       sleep .5
    done
end script

    Save file and exit editor.

  4. The /etc/init/mythtv-backend.conf file (at least for Mythbuntu 14.04.1) should now look like the following:

    ----- begin /etc/init/mythtv-backend.conf -----

    # MythTV Backend service

description     "MythTV Backend"
author          "Mario Limonciello <superm1@ubuntu.com>"

start on (local-filesystems and net-device-up IFACE!=lo and started udev-finish)
stop on runlevel [016]

#should die within 5 seconds, but we don't want data loss, so set it to 30
#before we send SIGKILL
kill timeout 30

#if we crash, but not quickly
respawn
respawn limit 2 3600

#because we're daemonizing to avoid logging to upstart log
expect fork

pre-start script
    mythtv-findhdhr || true
    [ -x /usr/sbin/mysqld ] || exit 0
    for i in `seq 1 30` ; do
       /usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping >/dev/null && exit 0
       sleep .5
    done
end script

script
    test -f /etc/default/locale && . /etc/default/locale || true
    LANG=$LANG exec /usr/bin/mythbackend --syslog local7 --user mythtv --daemon
end script

    ----- end /etc/init/mythtv-backend.conf -----

2017-05-29 Implemented this proposed solution.

2017-06-04 This proposed solution worked reasonably well, but was not foolproof in that we did encounter a situation wherein the HDHomeRun network tuner was not found. A further option which we did not try would be to slowdown MythTV boot up by switching the Operating System drive from an SSD to a HDD. For now we decided to set this PVR to stay powered on using the MythWelcome Lock Shutdown option. This minimizes the power cycles on/off and hence reduces the chance that the HDHomeRun tuner is not found.

2019-01-10 Still need to try proposed solution E.

Proposed Solution E: Add CRON on Reboot Wait Script

Create a script to test for the existence of the HDHomeRun network tuner then restart mythtv backend. Configure root cron to run this script once on each reboot of the computer.

Credit for sharing this proposed solution goes to Scott Catterton (mapsmehere at iCloud dot com). Thank you Scott. :-)

  1. Create /usr/bin/mythtv-hdhr-bandaid.sh file for cron reboot script.

    sudo leafpad /usr/bin/mythtv-hdhr-bandaid.sh

    Insert the following lines:

    ----- begin mythtv-hdhr-bandaid.sh -----

    #!/bin/bash
#
# Wait for presence of HDHomeRun network tuner device
# and when found restart the mythtv backend
#
WAITFORHDHR=0

while [ "$WAITFORHDHR" = "0" ]; do
  echo "Waiting for HDHomeRun to respond"
  sleep 1
  hdhomerun_config discover && WAITFORHDHR=1
done

if [ "$WAITFORHDHR" != "0" ]; then
  # Restart MythTV Backend
  #
  #   For Ubuntu 14.04 (with upstart) use:
  service mythtv-backend restart
  #
  #   For GNU/Linux distro (with systemd) try something like:
  #     systemctl restart mythtv-backend
fi

    ----- end mythtv-hdhr-bandaid.sh -----

    Save file and exit editor.

  2. Make the script executable.

    sudo chmod 755 /usr/bin/mythtv-hdhr-bandaid.sh

  3. Schedule the script to run under the root user.

    sudo crontab -e

    Copy and append the following lines:

    ----- begin root crontab lines -----

    #
# Wait for HDHomeRun then restart mythbackend
@reboot /usr/bin/mythtv-hdhr-bandaid.sh > /dev/null 2>&1

    ----- end root crontab lines -----

    The @reboot syntax in the crontab will schedule the script for execution once on each reboot.

    2019-01-10: Note that I have not yet had an opportunity to test this method.
