MythTV works just fine on OSX (but see the gotchas below).  To watch TV at acceptable speeds, you'll want at least an 800 MHz G4 or better. For HDTV nearly any Intel-based Mac released from 2008 onwards will suffice.  MythTV will not use GPU acceleration on OSX until {{Ticket|2381}} or an equivalent has been finished.

To watch TV at acceptable speeds, you'll want at least an 800 MHz G4 or better. For HDTV nearly any Intel-based Mac released from 2006 onwards will suffice, though newer machines will allow the use of better deinterlacers for 1080i content.
 +
 
 +
=== Backend ===
 +
 
 +
The backend takes very little CPU power, except when marking commercials.  Any Mac capable of running OSX 10.5 Leopard or later will work fine.

= Using MythFrontend =
 +
 +
'''MythFrontend''' is a normal OSX app that has no special dependencies to run. Version 0.27 is officially supported on 10.8 and 10.9.  Version 0.25 through 0.26 are compatible with 10.5 to 10.7. Older versions are compatible with versions of OSX from 10.3.x (Panther) through 10.6.x (Snow Leopard).
 +
 +
{{Warning}} Note: in order for the MythTV Frontend to do anything useful you must first have a MythTV backend installed and configured. Additionally the frontend and backend generally need to be the same major version to work together.
  
 +
The first time you run '''MythFrontend''', it will enter a setup mode where you must configure the details of its access to the backend, and its display options.  For v0.25 the frontend must be configured to use OpenGL. See [[ForcingOpenGL|here]] for instructions.
  
You're now ready to run mythfrontend! Find the MythFrontend.app icon and double click it to start mythfrontend. If it doesn't start, open a console window to see the mythfrontend output which may give you some clues as to what's wrong.
+
See the [http://www.mythtv.org/wiki/User_Manual:Detailed_configuration_Frontend User Manual] for more information on configuring the frontend.
 +
  
= Installing MythTV Backend on Mac OS X using prebuilt binaries =
 
  
{{Note box| To use an OS X backend, it may be easier to start with a Linux machine running a recent SVN version of MythTV to act as a backend. If you've never installed MythTV, you can first set up Linux version such as MythBuntu, and only look at the OS X version once everything's working properly there. That said, don't be discouraged; many people use a OS X with FireWire STBs, IPTV, and the HD Home Run.}}
+
==== Accessing MythWeb ====
  
 +
To watch streamed video on [[MythWeb]] servers from OSX, you may have to [[MythWeb_client_on_Mac_OS_X|alter the treatment of streaming files]].
  
{{Warning}} '''The prebuilt MythBackend.app binaries from 0.21-fixes do not work on Snow Leopard as of 20090921 SVN Revision 21625. The status of 0.22 is unknown.  It's recommended you wait to upgrade to Snow Leopard if you rely on MythBackend.app'''
+
= Installing MythTV Backend =
 +
 
 +
The MythTV backend and its MySQL database run smoothly on OSX.
 +
Setting up the backend is somewhat more complicated than when using prebuilt Linux distributions such as MythBuntu. Inexperienced users who run into trouble may wish to gain experience with MythTV on Linux as training for setting it up on OSX.
 +
 
 +
The main additional complexities of installing the backend on OSX are
 +
* Installing MySQL
 +
* Setting initial MySQL database and permissions
  
  
== Install Wget ==
 
The MythFillDatabase program (fetches schedule info) depends on ''wget'' which is not included in the default install of Mac OSX. It can be installed [http://www.statusq.org/archives/2008/07/30/1954/ directly], via Fink or MacPorts, or by [http://www.gnu.org/software/wget/ downloading] and building it. <code>MythTV-Setup.app</code> also uses ''wget'' when trying to obtain the channel list so one must install ''wget'' before trying to use the backend.
 
  
 
== Set Up MySQL ==

==== Download and Install ====
 
==== Download and Install ====
  
Grab and install MySQL 5.0 for Mac OS X from the [http://dev.mysql.com/downloads/mysql/5.0.html#macosx-dmg Mysql site].
+
Grab and install MySQL 5.1 for Mac OS X from the [http://dev.mysql.com/downloads/mysql/5.1.html#macosx-dmg Mysql site].  Either the 32-bit or 64-bit version is fine, except for Australian users running OSX 10.7 who will need 64-bit libraries to run [http://svn.whuffy.com/ shepherd] for TV guide data.
 +
 
 +
For controlling the MySQL database server, you can choose one of the following options:
 +
 
 +
# Set up the database server without locking it to a user account by installing '''MySQLStartupItem.pkg'''.  More information for the curious is [[MySQL_For_Myth_on_Mac_OS_X|here]].
 +
# Choose a user account responsible for running the database server, then install '''MySQL.prefPane''' for that account.  You will almost certainly want to use ''System Preferences -> Accounts'' to make that account automatically login.
  
 
==== Server Startup ====
 
==== Server Startup ====
After installation, the mysql server needs to be started. The MySQL distribution [http://dev.mysql.com/doc/refman/5.0/en/mac-os-x-installation.html sets itself] to start automatically on boot by creating a startup item called ''/Library/StartupItems/MySQLCOM'' and setting a value in ''/etc/hostconfig''.  Therefore the easiest way to start the ''mysqld'' daemon is simply to reboot after installing MySQL.  To start MySQL manually you can use <code>/usr/local/bin/mysql/bin/mysqld</code>.  This may prompt an error message for lack of access to the directory.  If it does type <code>chmod oug+rwX directory</code> to enable it, then start the database server again.
+
After installation, the MySQL server needs to be started.
 +
 
 +
* Reboot and the server will start automatically if you used the Startup Item.
 +
* If you have installed '''MySQL.prefPane''' preference pane instead
 +
** Go into System Preferences and select '''MySQL''' in the ''Others'' category
 +
** Check ''Automatically Start MySQL on Startup''
 +
** Click on the '''Start MySQL''' button.
  
 
==== Initial Database Setup ====
 
==== Initial Database Setup ====
  
Open <code>Terminal</code>.  Type in the following and press enter:  
+
Open '''Terminal'''.  Type in the following and press enter:  
<pre>
+
 
cd /usr/local/mysql/bin/
+
''shell> ''cd /usr/local/mysql/bin/
</pre>
+
 
 +
Here, the <code>''shell> ''</code> characters indicate the shell prompt, not something you need to type.
 +
 
 +
===== Configuring Default Database Users =====
 +
 
 +
Enter the specialized MySQL shell
 +
 
 +
''shell> ''./mysql -u root
 +
 
 +
which should start and prompt you for input with the <code>mysql></code> prompt.
 +
 
 +
Delete the anonymous MySQL accounts by entering the following command:
 +
 
 +
 
 +
<pre>mysql> DROP USER ''@'localhost';</pre>
  
Delete the anonymous mysql accounts by entering the following commands:
 
<pre>
 
shell> ./mysql -u root
 
mysql> DROP USER '';
 
</pre>
 
  
 
If you don't know your machine's hostname, look it up in the table produced by entering
 
If you don't know your machine's hostname, look it up in the table produced by entering
<pre>
 
mysql> SELECT Host, User FROM mysql.user;
 
</pre>
 
  
Then, set passwords for root account by entering the below commands and substituting your desired password for ''newpwd'' and your backend machine's hostname for ''host_name''.
+
''mysql> ''SELECT Host, User FROM mysql.user;
<pre>
+
 
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');
+
 
mysql> SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd');
+
Then, set passwords for the root account by entering the below commands and substituting your desired password for ''newpwd'' and your backend machine's hostname for ''host_name''.
</pre>
+
 
 +
''mysql> ''SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');
 +
''mysql> ''SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('newpwd');
 +
''mysql> ''SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd');
 +
''mysql> ''SET PASSWORD FOR 'root'@'host_name.local' = PASSWORD('newpwd');
 +
 
 +
This root password is not one you will generally have to share, but you should [http://www.howtoforge.com/reset-forgotten-mysql-root-password definitely] make a record of it.
 +
 
 +
===== Database Privileges and Character Set =====
 +
 
 +
Finally, create the ''mythtv'' user and <code>mythconverg</code> database in MySQL, substituting your desired password for that user where it says ''mythtv-password'':
 +
 
 +
 
 +
''mysql> ''CREATE DATABASE IF NOT EXISTS mythconverg;
 +
''mysql> ''GRANT ALL ON mythconverg.* TO mythtv@localhost IDENTIFIED BY "mythtv-password";
 +
''mysql> ''FLUSH PRIVILEGES;
 +
''mysql> ''GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv@localhost IDENTIFIED BY "mythtv-password";
 +
''mysql> ''FLUSH PRIVILEGES;
 +
''mysql> ''ALTER DATABASE mythconverg DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
 +
 
 +
 
 +
This MythTV password will be given to any frontend you use, and is therefore going to be kept relatively insecure, so don't choose a password that is important to you.  The customary choice for this password is ''mythtv''.
 +
 
 +
The above commands are equivalent to the [https://github.com/MythTV/mythtv/blob/master/mythtv/database/mc.sql setup script] that runs automatically when you install MythTV on Linux distributions.
  
 +
If you will be watching TV on other computers using this backend, you will need to [http://stackoverflow.com/questions/6401218/granting-mysql-access-rights-to-all-machines-on-subnet create database permissions] for them as well. One common invocation is
  
Finally, create the ''mythtv'' user and database in MySQL, substituting your desired password for that user where it says "mythtv-password":
+
''mysql> ''GRANT ALL PRIVILEGES ON mythconverg.* TO 'mythtv'@'192.168.1.0/255.255.255.0' IDENTIFIED BY "mythtv-password";;
 +
''mysql> ''GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO 'mythtv'@'192.168.1.0/255.255.255.0' IDENTIFIED BY "mythtv-password";
 +
''mysql> ''FLUSH PRIVILEGES;
  
<pre>CREATE DATABASE if not exists mythconverg;
+
See the [http://dev.mysql.com/doc/refman/5.1/en/account-names.html MySQL manual] if you need more information on permissions.
GRANT ALL ON mythconverg.* TO mythtv@localhost IDENTIFIED BY "mythtv-password";
 
FLUSH PRIVILEGES;
 
GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv@localhost IDENTIFIED BY "mythtv-password";
 
FLUSH PRIVILEGES;
 
ALTER DATABASE mythconverg DEFAULT CHARACTER SET latin1;
 
</pre>
 
  
The above commands are equivalent to the setup script that runs automatically when you install MythTV on other *nix distributions.
+
=== Finishing Backend Setup ===

=== Method 1: Login Item ===
 +
Make '''MythBackend''' a Login Item for the DVR user, using the Accounts section of System Preferences.
  
One way to start the backend is to make it a Login Item for the DVR user using the Accounts section of the control panel.  However, MythBackend is really a daemon, and it is nice to control it as such.  The approved way to automatically start processes in OSX is to use <code>launchd</code>.  Placing the following property list in <code>~/Library/LaunchAgents/MythBackend.plist</code> of the relevant user account will cause MythBackend to be started whenever that user logs in, and restarted if killed or crashed.

= Setting up MythWeb =
 +
 +
'''MythWeb''' is a convenient collection of website code that lets you set up recordings, browse the schedule, and review existing recordings without having to start the complete frontend.  Since Macs have a built-in webserver, it's pretty simple to get [[MythWeb]] going as well.  For complete setup instructions, please see [[MythWeb_on_Mac_OS_X_Backend|the OSX-specific instructions]].

==== Limited Tuners ====
 
==== Limited Tuners ====
As of v0.21, the Mac OS X backend does not support the majority of tuners listed as being supported by the (Linux) version of MythTV.  The following tuners are known to work using the Mac version of Myth backend: HDHomeRun. Recording via firewire from set top boxes such as the Motorola 6412 or Motorola DCT 6200 is also known to work. Plans (if any) for additional support are unknown.

(As of mythtv 21-fixes-20090215)  Multicore machines are likely to run afoul of bug {{Ticket|5832}}, crashing setup while trying to perform a scan for channels.  While on some operating systems one can use the <code>taskset</code> command to restrict to a single core, OSX lacks any equivalent.  The problem is claimed to be fixed in the "mythtv-channel-scan" branch of SVN, but as of this writing no prebuilt backend binaries are available for this branch.  The best workaround is presently to set up a temporary backend on Linux, scan channels, and then copy the <code>channel</code> and <code>dtv-multiplex</code> tables back to the Mac using <code>mysqldump</code>. (Not everyone runs into this problem)
 
  
 
==== Firewire Recording ====
 
==== Firewire Recording ====
  
(As of mythtv 0.21-fixes-20090316) There is one important note if trying to record via FireWire on an Intel Mac. The MythBackend cannot get a LAM lock signal when recording TV via FireWire. The solution is to check the "Open with Rosetta" checkbox on the Get Info panel of MythBackend.app. See [http://www.gossamer-threads.com/lists/mythtv/users/352434#352434 this post] for information.

If you build MythBackend yourself using MacPorts, [https://www.mythtv.org/wiki/Building_Myth_for_Mac_with_MacPorts Building Myth for Mac with MacPorts] it is possible to enable firewire recording during compilation. This is known to work with mythtv.28-0.28.1-Fixes running on an Intel Mac Mini (late 2012) under Mac OS High Sierra (10.13.1) on a Motorola DCX 3400 M cable box.

If you are running an older pre-compiled version of MythBackend (as of mythtv 0.21-fixes-20090316) and cannot get a [[Channel tuning|LAM lock]] signal when recording TV via FireWire.

Because of this, it's important to open MythBackend.app from the Finder and not from a Terminal window because it won't open with Rosetta. There must be some PPC-specific FireWire code in there.

==== Surround Sound in 7.1 Channels ====
 +
To activate 7.1 audio (using either HDMI or DisplayPort); make sure to first launch the Audio MIDI Setup in <code>/Application/Utilities</code> and configure HDMI audio as 8 channels-24 bits (the default is just stereo). It is recommended to disable DTS and AC3 passthrough as it would reset the hdmi audio in two channels mode, which would break future multi-channels playback.
 +
Note that for the time being, E-AC3, TrueHD and DTS-HD MA bitstreaming do NOT work under MacOS. That's until Apple provide the required 192kHz digital sampling rate (the hardware supports it!).

 +
==== GPU Acceleration ====
 +
The frontend can accelerate H.264 video using the [[VDA|Video Decode Acceleration]] (VDA) GPU library, if available.
 +
 +
==== Display Scale Hacks ====
 +
Menus, titlebars and other text may be cut off on high-resolution televisions driven by your Mac, or be too small to see from a distance, which interferes with the ability to use your it as a standard computer. You can change the display scale to make applications appear better.  To do this, modify the global scale factor
 +
 +
''shell> ''defaults write NSGlobalDomain AppleDisplayScaleFactor 1.25
 +
 +
(To reset the scale just run the above commands both with a scale of 1.0.)
 +
 +
The scale factor (1.25) increases the OSX system fonts by 25%. Myth won't like this (and doesn't need it) so you need to force the scale factor for Myth back to the default 1.0.    For MythTV and any other app you wish to render on the with normal fonts, you can modify the app-specific scale factor like this
 +
 +
''shell> ''defaults write net.psychosis.MythFrontend AppleDisplayScaleFactor 1.0
 +

Underpowered systems may do best with the Kernel deinterlacer, or Linear Blend if that's still taxing your CPU. Newer systems should be able to run Yadif or Greedy HIghMotion, which provide significantly better deinterlacing than the previous options.

Latest revision as of 00:50, 1 March 2021

New users: before attempting to install MythTV for the first time, please familiarize yourself with the distinction between frontend and backend.

MythTV works just fine on OSX (but see the backend gotchas below).

Hardware Requirements

Frontend

To watch TV at acceptable speeds, you'll want at least an 800 MHz G4 or better. For HDTV nearly any Intel-based Mac released from 2006 onwards will suffice, though newer machines will allow the use of better deinterlacers for 1080i content.

Backend

The backend takes very little CPU power, except when marking commercials. Any Mac capable of running OSX 10.5 Leopard or later will work fine.

Using MythFrontend

MythFrontend is a normal OSX app that has no special dependencies to run. Version 0.27 is officially supported on 10.8 and 10.9. Version 0.25 through 0.26 are compatible with 10.5 to 10.7. Older versions are compatible with versions of OSX from 10.3.x (Panther) through 10.6.x (Snow Leopard).

Warning.png
Note: in order for the MythTV Frontend to do anything useful you must first have a MythTV backend installed and configured. Additionally the frontend and backend generally need to be the same major version to work together.

The first time you run MythFrontend, it will enter a setup mode where you must configure the details of its access to the backend, and its display options. For v0.25 the frontend must be configured to use OpenGL. See here for instructions.

See the User Manual for more information on configuring the frontend.


Accessing MythWeb

To watch streamed video on MythWeb servers from OSX, you may have to alter the treatment of streaming files.

Installing MythTV Backend

The MythTV backend and its MySQL database run smoothly on OSX. Setting up the backend is somewhat more complicated than when using prebuilt Linux distributions such as MythBuntu. Inexperienced users who run into trouble may wish to gain experience with MythTV on Linux as training for setting it up on OSX.

The main additional complexities of installing the backend on OSX are

  • Installing MySQL
  • Setting initial MySQL database and permissions


Set Up MySQL

The MythTV backend relies on having a MySQL database available for storing information about upcoming and past recordings, channel setup, and the like.

Download and Install

Grab and install MySQL 5.1 for Mac OS X from the Mysql site. Either the 32-bit or 64-bit version is fine, except for Australian users running OSX 10.7 who will need 64-bit libraries to run shepherd for TV guide data.

For controlling the MySQL database server, you can choose one of the following options:

  1. Set up the database server without locking it to a user account by installing MySQLStartupItem.pkg. More information for the curious is here.
  2. Choose a user account responsible for running the database server, then install MySQL.prefPane for that account. You will almost certainly want to use System Preferences -> Accounts to make that account automatically login.

Server Startup

After installation, the MySQL server needs to be started.

  • Reboot and the server will start automatically if you used the Startup Item.
  • If you have installed MySQL.prefPane preference pane instead
    • Go into System Preferences and select MySQL in the Others category
    • Check Automatically Start MySQL on Startup
    • Click on the Start MySQL button.

Initial Database Setup

Open Terminal. Type in the following and press enter:

shell> cd /usr/local/mysql/bin/

Here, the shell> characters indicate the shell prompt, not something you need to type.

Configuring Default Database Users

Enter the specialized MySQL shell

shell> ./mysql -u root

which should start and prompt you for input with the mysql> prompt.

Delete the anonymous MySQL accounts by entering the following command:


mysql> DROP USER ''@'localhost';


If you don't know your machine's hostname, look it up in the table produced by entering

mysql> SELECT Host, User FROM mysql.user;


Then, set passwords for the root account by entering the below commands and substituting your desired password for newpwd and your backend machine's hostname for host_name.

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');
mysql> SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('newpwd');
mysql> SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd');
mysql> SET PASSWORD FOR 'root'@'host_name.local' = PASSWORD('newpwd');

This root password is not one you will generally have to share, but you should definitely make a record of it.

Database Privileges and Character Set

Finally, create the mythtv user and mythconverg database in MySQL, substituting your desired password for that user where it says mythtv-password:


mysql> CREATE DATABASE IF NOT EXISTS mythconverg;
mysql> GRANT ALL ON mythconverg.* TO mythtv@localhost IDENTIFIED BY "mythtv-password";
mysql> FLUSH PRIVILEGES;
mysql> GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv@localhost IDENTIFIED BY "mythtv-password";
mysql> FLUSH PRIVILEGES;
mysql> ALTER DATABASE mythconverg DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;


This MythTV password will be given to any frontend you use, and is therefore going to be kept relatively insecure, so don't choose a password that is important to you. The customary choice for this password is mythtv.

The above commands are equivalent to the setup script that runs automatically when you install MythTV on Linux distributions.

If you will be watching TV on other computers using this backend, you will need to create database permissions for them as well. One common invocation is

mysql> GRANT ALL PRIVILEGES ON mythconverg.* TO 'mythtv'@'192.168.1.0/255.255.255.0' IDENTIFIED BY "mythtv-password";;
mysql> GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO 'mythtv'@'192.168.1.0/255.255.255.0' IDENTIFIED BY "mythtv-password";
mysql> FLUSH PRIVILEGES;

See the MySQL manual if you need more information on permissions.

Finishing Backend Setup

Now download the backend (from one of the servers above).

Launch MythTV-Setup.app and go through the configuration steps.

You're done! Watch and record TV using MythFrontend.app.

Automatic Backend Startup

Method 1: Login Item

Make MythBackend a Login Item for the DVR user, using the Accounts section of System Preferences.

Method 2: Launchd

MythBackend is really a daemon, and it is nice to control it as such. The approved way to automatically start processes in OSX is to use launchd. Placing the following property list in ~/Library/LaunchAgents/MythBackend.plist of the relevant user account will cause MythBackend to be started whenever that user logs in, and restarted if killed or crashed.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>KeepAlive</key>
	<true/>
	<key>Label</key>
	<string>MythBackend</string>
	<key>ProgramArguments</key>
	<array>
		<string>/Applications/MythBackend/MythBackend.app/Contents/MacOS/MythBackend</string>
		<string>--logpath</string>
		<string>/var/log/MythBackend</string>
	</array>
</dict>
</plist>

where we have assumed that MythBackend.app resides in a MythBackend subfolder of /Applications.

To have MythBackend run as a specific user, insert the following under </array>, substituting mythtv with the username of your choice.

<key>UserName</key>
<string>mythtv</string>

Also, don't forget to create and set the correct permissions for the log file

sudo touch /var/log/MythBackend
sudo chown mythtv /var/log/MythBackend

Note that the path to the MythBackend application binary should be set to where you happen to keep it. If you need to stop the process, you cannot just kill it. Instead use

launchctl unload -w ~/Library/LaunchAgents/MythBackend.plist

and once you are ready to start it again type

launchctl load -w ~/Library/LaunchAgents/MythBackend.plist

in a Terminal window.

Setting up MythWeb

MythWeb is a convenient collection of website code that lets you set up recordings, browse the schedule, and review existing recordings without having to start the complete frontend. Since Macs have a built-in webserver, it's pretty simple to get MythWeb going as well. For complete setup instructions, please see the OSX-specific instructions.

Gotchas and Warnings

Limited Tuners

Most PCI video capture cards lack OSX drivers, so the Mac OS X backend does not support the majority of tuners listed as being supported by (the Linux version of) MythTV.

The HDHomeRun network tuner is well known to work using the Mac version of Myth backend. Recording via firewire from set top boxes such as the Motorola 6412 or Motorola DCT 6200 is also known to work. There are no current plans for additional hardware support.

HDPVRCapture on Mac describes how to use HDPVRCaputre to record on Mac OS X with a Hauppauge HDPVR.

Firewire Recording

If you build MythBackend yourself using MacPorts, Building Myth for Mac with MacPorts it is possible to enable firewire recording during compilation. This is known to work with mythtv.28-0.28.1-Fixes running on an Intel Mac Mini (late 2012) under Mac OS High Sierra (10.13.1) on a Motorola DCX 3400 M cable box.


If you are running an older pre-compiled version of MythBackend (as of mythtv 0.21-fixes-20090316) and cannot get a LAM lock signal when recording TV via FireWire. The solution is to check the "Open with Rosetta" checkbox on the Get Info panel of MythBackend.app. See this post for information.

Because of this, it's important to open MythBackend.app from the Finder and not from a Terminal window because it won't open with Rosetta. There must be some PPC-specific FireWire code in there.

This method had successfully been used to record HD over FireWire on a Intel Mac Mini (Macmini3,1) on a Motorola DCT 6200 cable box.

Troubleshooting and Monitoring

Process View and CPU Usage

To see if you have processes running, you can use the ps command in a terminal, or even better, you can use the Activity Monitor supplied by Apple (usually found in /Applications/Utilities/). Sort by process name. You should see MySQL as mysqld and MythBackend as MythBackend.

Log Files

By default, MythBackend and MythFrontend log to standard output (often /var/log/system.log).

It is convenient to separate the backend log from the general system log. If you launch the backend with the -l logfilename directive then it will log to logfilename instead. You can view the logs with tail in a command-line window, or more conveniently using Console.app, also in /Applications/Utilities/.

MythFillDatabase sends messages both to the standard output and the standard error. You may like to similarly redirect that output.

MythTV_Setup.app Exit code 153 / Setup Timezone tables

If the MythTV_Setup.app from MythTV Backend goes through the connection to the MySQL server and then just aborts, verify you have the timezone information loaded into you MySQL installation. Follow the steps described in MySQL Time Zone Tables and it might help to get it working for you.

Tips and Tricks

Remote Control

Apple Remote

The Apple Remote can be used to control the most common MythTV functions:

  • Directional keys: arrow keys
  • Play/Pause: Enter
  • Menu: Escape

Holding down buttons will generate alternate inputs:

  • Hold Play/Pause: P (play/pause playback)
  • Hold Menu: M (Menu in playback)
  • Hold Left/Right: Home/End

See the Keybindings page for what these key equivalents will do in any given situation. Keybindings can be altered in the settings menu using MythWeb. For example you may wish to try changing the "Pause" setting for TV Playback from P to P,Enter to support the play/pause button on the Apple Remote.

Other Infrared Remotes

See Keyspan Express Remote.

iPhone/iTouch Control

Web-based remotes such as MyMote and others found here or here should in principle work fine with an iPhone and OSX setups. Some features of MyMote may require LIRC.

Android Control

The android app Mythmote can be used to control your mythtv frontend. Enable the Network control under Setup -> General -> Network Control.

Computer To Computer Network Control

If you want to try controlling MythTV from another Mac (perhaps by a PowerBook from the couch), Generally Helpful Software has released an early beta of a remote control application, Remote Remote GH for MythTV http://web.mac.com/grhowes/iWeb/Generally%20Helpful%20Software/Remote%20Remote%20GH.html

Another Mac OS X network remote control is available at http://ignasiak.googlepages.com/mythremote

Surround Sound in 7.1 Channels

To activate 7.1 audio (using either HDMI or DisplayPort); make sure to first launch the Audio MIDI Setup in /Application/Utilities and configure HDMI audio as 8 channels-24 bits (the default is just stereo). It is recommended to disable DTS and AC3 passthrough as it would reset the hdmi audio in two channels mode, which would break future multi-channels playback. Note that for the time being, E-AC3, TrueHD and DTS-HD MA bitstreaming do NOT work under MacOS. That's until Apple provide the required 192kHz digital sampling rate (the hardware supports it!).

GPU Acceleration

The frontend can accelerate H.264 video using the Video Decode Acceleration (VDA) GPU library, if available.

Display Scale Hacks

Menus, titlebars and other text may be cut off on high-resolution televisions driven by your Mac, or be too small to see from a distance, which interferes with the ability to use your it as a standard computer. You can change the display scale to make applications appear better. To do this, modify the global scale factor

shell> defaults write NSGlobalDomain AppleDisplayScaleFactor 1.25

(To reset the scale just run the above commands both with a scale of 1.0.)

The scale factor (1.25) increases the OSX system fonts by 25%. Myth won't like this (and doesn't need it) so you need to force the scale factor for Myth back to the default 1.0. For MythTV and any other app you wish to render on the with normal fonts, you can modify the app-specific scale factor like this

shell> defaults write net.psychosis.MythFrontend AppleDisplayScaleFactor 1.0


Playback Settings

In the setup screens, explore the "TV Settings" -> "Playback" options. You'll find two pages of Mac-specific settings there. If your machine isn't fast enough, you can choose to drop frames here. If you have cycles to spare, you'll find fun settings like video in the Dock, on the Desktop, or in a floating (and optionally translucent) window.

MythGrowl Notifications

There is an application for Mac OS X called MythGrowl that generates Growl notifications when your MythTV backend starts or finishes a recording. Not part of Mythfrontend but worth a mention. It can be downloaded at http://mythgrowl.sourceforge.net/

Performance Tweaks for Underpowered Systems

Performance with interlaced 1080i video is significantly affected by the choice of deinterlacer. Builds preceding v0.24 do not properly support the "2x" deinterlacers for 1080i60 (but they do for 480i), so if you are using one of those, try the "normal" version. Underpowered systems may do best with the Kernel deinterlacer, or Linear Blend if that's still taxing your CPU. Newer systems should be able to run Yadif or Greedy HIghMotion, which provide significantly better deinterlacing than the previous options.

Running TV playback in a smaller window can also improve performance, as can customising your backend recording settings. (E.g. Smaller capture from analog cards, 44.1KHz audio is a better match to some Macs than 48KHz.)

Shutdown/Reboot

Under General, enter the following to properly shutdown under OSX. You might also have to "sudo chmod +s /sbin/halt /sbin/reboot" to be able to execute the command as a non-super user.

  • To Shutdown: /sbin/halt
  • To Reboot: /sbin/reboot

Then add shutdown/Reboot to mythfrontend exit menu.

Disable Bluetooth Keyboard setup

When a keyboard and/or mouse isn't plugged in the Bluetooth setup wizard will be displayed. To shut this off under OSX, go to settings->bluetooth->advanced, uncheck the keyboard wizard.

Disable Mouse Cursor

Hide mouse cursor option. Select this to hide your mouse cursor. Useful for headless (mouseless and keyboardless) setups. If you don't enable this, your cursor will disappear only after moving the mouse. settings->appearance->Hide Mouse Cursor in Mythtv.

Auto Startup

Start the mythfrontend app automatically upon login. settings->users->login items

VNC Server

Install an alternative VNC server if your VNC clients have trouble connecting to the built in one. I use VineVNC server.

  • The user manual at User_Manual:Index has a lot of material, though it is Linux-oriented
  • For MythTV on Mac OS X on Intel machines, there is also also Myth on Mac x86. (However, that page is very out of date in many respects.)
