Database Configuration 1/2

Database Configuration 1/2
Setting Default Value Settings Page's Description Additional Comments
Hostname 127.0.0.1 The hostname or IP address of the machine hosting the database. This information is required If you are running a single combined backend and frontend, then leave this at its default value of 127.0.0.1. This is often referred to as the local loopback IP address. If you have multiple frontends connecting to this backend then you will need to set this address to the same address as the its real IP address eg 192.168.2.11 as it appears on your network. If you have a DNS Server running on your network you can just put the hostname eg "MythBackend". Your DNS Server will translate this to its real IP address.
Database mythconverg The name of the database. This information is required This is the name of the database the MythTV backend uses to store information. Normally you should not need to change this. However, you may choose to have different databases for different reasons, for example, a test database so you can check out configurations, and then put this back to mythconverg later, or a different database depending on user, so each user can have their own look and feel.
User mythtv The user name to use while connecting to the database. This information is required You should not have to change this from its default.
Password mythtv The password to use while connecting to the database. This information is required Change this to suit your system
Database type MySql The database implementation used for your server MySql is an Opensource database used by MythTV to hold all of its internal information.

Setting Default Value Settings Page's Description Additional Comments
Custom Identifier for Frontend Preference Unchecked If this frontend's hostname changes often, check this box and provide a network-unique name to identify it. If unchecked, the frontend machine's local hostname will be used to save preferences in the database. This is the meat of the subject
Use Wake-on-LAN to Wake Database Unchecked If checked, the frontend will use Wake-On-LAN parameters to reconnect to the database server (Mythbackend) Wake-On-LAN is an ACPI option that allows your machine to powerup based on activity on the network. You need to makes sure that your machine supports ACPI correctly for this to work. You can use this remotely activate your machine for instance when you are at work.

Audio

Audio
Setting Default Value Settings Page's Description Additional Comments
Audio output device /dev/dsp Blank This is the sound card that you want to use.

To specify an ALSA device, use the format ALSA:device (where device is a valid ALSA device such as spdif; iec958; default; hw::0,0; plughw:0,0; etc.). For example, ALSA:spdif.
You can find out which ALSA devices you have available, with the command

aplay -l
Enable AC3 to SPDIF passthrough Unchecked Enable sending AC3 audio directly to your sound card's SPDIF output. on sources which contain AC3 soundtracks (usually digital tv). Requires that the sudio output device be set to something suitable AC3 is Dolby Digital surround. You will need to connect your Myth box to your surround receiver via a Optical or coaxial connector. Raw AC3 Stream is passed through to your receiver which will decode the surround. This is the preferred method for best audio quality, and also takes the audio processing load from your machine.

For more information on setting up digital audio, see the Configuring Digital Sound page.

Agressive soundcard buffering Off If enabled, MythTV will pretend to have a smaller sound card buffer than is really present. This may speed up seeking, but can also cause playback problems. Where users have reported Audio stutter problems, enabling this setting seems to help.
Use Internal Volume Controls On MythTV can control the PCM and master mixer volume. If you prefer to use an external mixer program, then disable this option. Lightens the CPU's load when disabled. You may also want to disable this if you are using AC3 output as vol control will now be done by your surround amplifier or reciever
Select mixer device /dev/mixer Blank This is the meat of the subject
Mixer Controls PCM Changing the volume adjusts the selected mixer. Options are: PCM and Master.
Master mixer volume 0-100 (selects volume level) 70 Initial volume for the Master Mixer. This affects all sound created by the soundcard. Note: Do not set this too low. This is the meat of the subject
PCM mixer volume 0-100 (selects volume level) 70 Initial volume for PCM output. Using the volume keys in MythTV will adjust this parameter. This is the meat of the subject
Independent muting of left and right audio channels Off Enable muting of just the left or right channel. Useful if your broadcaster puts the original language on one channel, and a dubbed version of the program on the other one. This modifies the behavior of the Mute key. This is the meat of the subject

Setting Default Value Settings Page's Description Additional Comments
System Exit Key ESC (Escape) MythTV is designed to run continuously. If you wish, you may use the ESC key or the ESC key + a modifier to exit MythTV. Do not choose a key combination that will be intercepted by your window manager. Possible values are:
  • ESC
  • No exit key
  • Control-ESC
  • Meta-ESC
  • Alt-ESC
Confirm Exit (Checkbox) On When enabled, MythTV will prompt for confirmation when you press the System Exit key. This is the meat of the subject
Halt Command halt If you have configured an exit key using the System Shutdown option, you will be given the opportunity to exit MythTV or halt the system completely. Another possibility for this field is "poweroff". This is the meat of the subject
Keypress Command (none) External application or script to run when a keypress is received by LIRC. This is the meat of the subject
Use Arrow Key Accelerators On If enabled, Arrow key accelerators will be used, with LEF performing an exit action and RIGHT selecting the current item. This is the meat of the subject

Setting Default Value Settings Page's Description Additional Comments
Require setup PIN Off If set, you will not be able to return to this screen and reset the Setup PIN without first entering the current PIN. This is the meat of the subject
Setup PIN Codeg (none) This PIN is used to control access to the setup menus. If you want to use this feature, then setting the value to all numbers will make your life much easier. Set it blank to disable. This is the meat of the subject
Monitor CD/DVD Off This enables support for monitoring your CD/DVD drives for new disks and launching the proper plugin to handle them. This is the meat of the subject
Enable X-box Hardware Disabled This enables support for Xbox Specific hardware. Requires a frontend restart for changes to take effect. Enabling this option will add another button to the settings menu allowing configuration of your Xbox LED. You will need the Blink program from the xbox-linux project, which is installed as /bin/led on GentooX and /usr/bin/blink on Xebian. (Type which blink to see if the program is available.) If you do not have blink, you may obtain it from the Xbox-Linux project site at http://xbox-linux.sf.net/.

Once you have installed blink you will need to set permissions. blink needs write permission to the i2c device to function properly. There are three methods to accomplish this. First, you could run mythfrontend as root, which is the simplest method, but could potentially be a security risk. Next, you may make the blink binary setuid root, which allows non-privileged users to run a program with root capability. This is done by typing the command:

   $ su
   # chmod u+s /path/to/blink

If you select GentooX as the distribution led will be used as the blink binary name, otherwise, blink is used. Colors should be self explanatory. The update interval determines how often the frontend should poll the backend to determine if the status has changed.
