Installing MythTV 0.20 on Ubuntu Gutsy 7.10

Document Purpose

The purpose of this document is to guide the reader through the installation of MythTV0.20 on Ubuntu Gutsy 7.10. After completing this guide the reader will have a fullyfunctional MythTV Linux box that is capable of recording and playing digital television

as well as hosting your DVD and music collection, or streaming those media collectionsto other MythTV front-end machines elsewhere around your house and wider networks,even allowing access to your recordings via the web from outside of your home if desired.

Requirements

The following requirements are prerequisites for using this installation guide.

1. Ubuntu Gutsy 7.10 desktop CD (available from www.ubuntu.net)2. Hardware that is identical or comparable to that specified below

Example HardwareI used the hardware specified below. If you use the exact same hardware then your installation will work perfectly provided that you follow the instructions here accurately.However, if you use different hardware (such as a different model of TV tuner or graphicscard) then you should do some research first to check that the hardware you have chosenis compatible with Ubuntu Gutsy 7.10 and that it is it compatible with MythTV. Thesafest option for a stressful install is to use the hardware I’ve written this guide around.

Processor : AMD Athlon 64 X2 dual core processor

Motherboard : nFORCE 4M-A ATX

Memory : 2GB DDR2 RAM chip

Graphics Card : nVidia GeForce 7200 SeriesMedia Drives : LG DVD/CD re-writer internal drive

Tuner Card : Hauppauge WinTV Nova T-500 dual tuner

Network : Devolo Highspeed Ethernet Starter Kit (better than using Wireless)

Remotes : iPhone/iTouch, or use the remote that accompanied the Tuner

I wanted to point out a couple of things regarding my hardware setup. You will notice thatI’ve got video built into the motherboard, yet I also opted to install a separate graphicscard as well. The reason is that the separate graphics card will provide DVI output andhas a higher specification that the built-in one, which is important given that I need thegraphics card to deliver a clean crisp video image to the accompanying television.

Secondly, rather than installing a Wireless card I opted to use the built-in Ethernet portand connect it to a Devolo Ethernet adaptor that plugs into a power socket in the wall.These adaptors allow an 85mbps network connection to be established across the power circuit in your home. One adapter connects the network from the router to the mainscircuit and the other adaptor connects the mains circuit to your MythTV computer. This isespecially useful because Linux still has problems natively supporting many wirelesscards and this approach will give you a consistent fast network connection that will better facilitate streaming your media to other MythTV front-end PCs around your home.

One final point - get a lot of memory (1GB per TV channel you wish to be able to recordin parallel) and a large hard-disk. I fitted a 500GB hard-disk and was surprised how

quickly it filled up when I loaded on my DVD collection and started recording TV. Youcan never have enough memory and never have enough hard-disk space available to you!

Installing the base System

Installing Ubuntu

1. Install the hardware, insert the Ubuntu Gutsy CD into the DVD-drive and boot the PC

2. Highlight “Start or Install Ubuntu” and press F6 (Other Options)

3. Add “noapic” to the Boot Options. This is required to work around an issue withAMD 64 X2 processors hanging the OS. You may not need to include this step if youare using an alternative processor. If you are unsure you should add this option.

4. Run the Install program from the Ubuntu Desktop and follow the pictures below.

5. Select the language and region options for the installation

6. The partitioner will start up. When asked how you would like to partition your disk you should select manual . I created a 40GB partition for my root filesystem, a 10GB

swap partition, an optional 50GB partition for my network share and all the rest of myspace for my /var/ partition. The /var/ partition needs to be big because this is whereMythTV stores your media files by default. I installed a 500GB hard disk, so after losing 100GB for my root, swap and share partitions I had 400GB left for /var/.




Page 6 of 46

When creating the /var/ partition I used a JFS file system. This is a journalled filesystem and is also very efficient at handling large data files, such as media content.

7. Next provide your name and password details for the main account. We will besetting up a mythtv account later on, so for now just create an account in your own

name. You should also provide a name for your computer; I used mythtv as the name.

8. The installation of the core Ubuntu operating system will then commence. Go andgrab yourself a cup of tea and after a while you will be prompted to reboot your PC.

Enabling the Root User

1. First we need to enable the root user account. This is the account that we will be usingto install all the core services under. Root is considered to be a specially privilegedaccount, so be careful when issuing the commands in this installation guide.

sudo passwd root[sudo] password for username: [enter password ]Enter new UNIX password: [enter password ]Retype new UNIX password: [enter password again]passwd: password updated successfully

suPassword: [enter the password you selected above]




Page 7 of 46

Configuring the Network

1. You should now be logged in as the root user and therefore have the required privileges to change the system settings and install services and programs.

2. The first thing we need to configure is the networking so it uses a static IP address.

This is useful because you will need to know the IP address of this server in order toaccess it from other PCs (such as other MythTV Front-ends) or from the Internet.

vi /etc/network/interfaces

Enter the following, which will give you a static IP of 192.168.2.100:

auto loiface lo inet loopback

auto eth0

iface eth0 inet staticaddress 192.168.2.100netmask 255.255.255.0network 192.168.2.0broadcast 192.168.2.255gateway 192.168.2.1

Restart the networking service (the grey text is the response you will get from Linux):

/etc/init.d/networking restart* Reconfiguring network interfaces… [OK]

3. We will now set a hostname for the PC. This should be the full URL that you will useto access the PC remotely. I have a dynamic IP for my machine, so I use a domainname that I can manage the DNS for with ZoneEdit (http://dynamic.zoneedit.com)

vi /etc/hosts

Ensure the first three lines are as follows (I use www.davos.co.uk as my domain):

127.0.0.1 localhost127.0.1.1 mythtv192.168.2.100 www.davos.co.uk

Now set the hostname for the machine

echo www.davos.co.uk > /etc/hostname/bin/hostname –F /etc/hostname

Updating Aptitude

1. We now need to change the Aptitude Repositories used by Ubuntu. These are the places that Ubuntu looks when installing applications and services. I typically disablethe CD-ROM as a source (ensuring we always look on the web for the most recent)and I add a couple of the core repositories that are needed later on in this guide.

vi /etc/apt/sources.list

# Main Gutsy Repositories

2. Save the changes that you have made above, update the repository list and upgradethe base components currently installed on your system by typing the following. Theupgrade option can take a while depending on how old your original Ubuntu CD was.

sudo apt-get updatesudo apt-get –y upgrade




Page 9 of 46

Installing an SSH Server

1. Install an SSH server so that you can use a SSH client to access the PC:

sudo apt-get –y install ssh

Installing the Generic Services and Tools

1. Install additional generic software that will be required during this installation bytyping the command line below into your terminal. The applications being added hereinclude useful programs for compressing and uncompressing data (unzip and zip), for fetching data from web pages (curl) or mail servers (fetchmail), for compiling code(gcc and make) and for converting DOS files into UNIX files (apt-file and sysutils).

sudo apt-get –y install unzip zip curl fetchmail libarchive-zip-perl zlib1g-dev

libpopt-dev nmap openssl lynx gcc flex make ncftp libdb4.3-dev rar wput apt-filesysutils

2. Remove some of the inet services that are not required on a MythTV server:

update-inetd --remove daytimeupdate-inetd --remove telnetupdate-inetd --remove timeupdate-inetd --remove fingerupdate-inetd --remove talkupdate-inetd --remove ntalkupdate-inetd --remove ftpupdate-inetd --remove discard

Installing a Network Time Protocol Server

1. Install ntpdate to enable your clock to be automatically synchronised with an InternetTime server using NTP (Network Time Protocol). It is important for your clock to becorrect for timed recordings, otherwise you may miss programs you want to record.

sudo apt-get –y install ntpdate/etc/network/if-up.d/ntpdate

2. Add the ntpdate check to the weekly schedule:

touch /etc/cron.weekly/setclock.cronchmod +x /etc/cron.weekly/setclock.cronvi /etc/cron.weekly/setclock.cron

#!/bin/bash

clock=clock.psu.edu/usr/sbin/ntpdate -u $clock >& /dev/null

Installing the File Server Components

Creating User Accounts

1.

As well as using the PC as a MythTV back-end, I also use the PC as a network fileserver too. Therefore, it may be useful to have additional user accounts set up on the

machine. We already have one account setup for the main user, but you can add anadditional one by following the following steps (repeat as many times as necessary):

adduser [username]

Installing Samba File Sharing Daemon

1. Samba allows you to create shares on your Ubuntu server that are visible fromWindows PCs on your network. We plan to install Samba for two reasons; (1) so that

the recordings made by MythTV can be made easily available across the network toWindows PCs that are not running a MythTV Front-end, and (2) so that we can usethe server as a standard file server for holding work files. Below I show how to installSamba and create accounts for two users that I intend giving access to. The passwordsthat are created are for the Samba accounts only, and do not need to be the same

passwords that are used on the accounts for accessing the Ubuntu machine.

sudo apt-get -y install samba samba-doc smbclient smbfs

smbpasswd -a david

New SMB password: [enter password]Retype new SMB password: [re-enter password]

smbpasswd -a niamhNew SMB password: [enter password]Retype new SMB password: [re-enter password]

vi /etc/samba/smb.conf

Under the Share Definitions section, add the following definition. This will create awritable share under the path /shared/ on your Ubuntu server. We will need to createthis directory and set the permissions so that users can read and write appropriately.

[share]comment = Shared Network Drivewritable = yespath = /sharedpublic = yes

mkdir –p /shared/davidmkdir –p /shared/niamhchown david:david /shared/davidchown niamh:niamh /shared/niamh

/etc/init.d/samba restart

Test that you can connect to the server from Windows using \\192.168.2.100\share\

Configuring the Video Hardware

Installing the NVIDIA Graphics Drivers

1.

The next step is to install the NVIDIA graphics drivers for Ubuntu Linux. The easiestway to do this is to use the Envy script, which is an automated detection and

compilation script for NVIDIA and ATI drivers. The Envy script comes highlyrecommended by me. The project is maintained at http://albertomilone.com/ and thescript provides a very quick and pain-free installation of the NVIDIA graphics driver.

2. Follow the steps below to install the drivers for your NVIDIA card. Also, note thatwhen you upgrade your kernel you will need to reinstall the NVIDIA driver again.

Install the dependencies:

apt-get install html2text po-debconf debhelper dh-make dpatch fakeroot libstdc++5

module-assistant xserver-xorg-dev gettext intltool-debian gcc-3.3-base

Download and run Envy:

cd ~/wget http://albertomilone.com/ubuntu/nvidia/scripts/legacy/envy_0.9.10-0ubuntu6_all.debdpkg -i envy_0.9.10-0ubuntu6_all.debenvy -t

Installing Firmware for the Hauppauge WinTV Nova-T 500

1. Unfortunately the Hauppauge WinTV Nova-T 500 PCI Card does not work out of the box with Ubuntu Gutsy, you will need to install a revised version of the firmware to

get it operational. Firstly, prepare Aptitude by running the following commands:

sudo apt-get updatesudo apt-get upgradesudo apt-get dist-upgrade

2. Now download the latest version of the firmware from the website below and place itinto the /lib/firmware directory on your Ubuntu server (also available with this guide).

wget http://www.wi-bw.tfh-wildau.de/~pboettch/home/linux-dvb-firmware/dvb-usb-dib0700-1.10.fwcp dvb-usb-dib0700-1.10.fw /lib/firmware

3. Install the packages to build the Kernel modules:

apt-get -y install linux-headers-$(uname -r) build-essentialapt-get -y install mercurial

4. Download the Linux source (I’m using 2.6.22, but your version might be different):

apt-get -y install linux-sourcecd /usr/src/tar -xjvf linux-source-2.6.22.tar.bz2ln -s /usr/src/linux-source-2.6.22 /lib/modules/$(uname -r)/source

5.

Install the Video for Linux DVB drivers:

cd ~/hg clone http://linuxtv.org/hg/v4l-dvbcd v4l-dvb

apt-get -y install ncurses-devmake menuconfig

When the configuration screen appears you should disable the ACI mixer in the

Audio Devices for Multimedia section because this can sometimes cause errors in theaci.c module when you compile the source code.

makemake install

6. Enable the onboard amplifier (if not already done) to prevent poor reception:

vi /etc/modprobe.d/options

{add}

options dvb-usb-dib0700 force_lna_activation=1




Page 13 of 46

7. Load the modules and reboot the machine

make loadmodprobe dvb-usb-dib0700shutdown –h now

8. Check that the Tuner card loaded the firmware successfully. Type the following andlook for a line that says that the Hauppauge Nova-T 500 was successfully initialised.

dmesg | grep dvb[ 12.972000] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in cold state, will try to load a firmware[ 13.044000] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.10.fw'[ 13.780000] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm state.[ 13.780000] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.[ 14.392000] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.[ 14.960000] dvb-usb: schedule remote query interval to 150 msecs.[ 14.960000] dvb-usb: Hauppauge Nova-T 500 Dual DVB-T successfully initialized and connected.[ 14.960000] usbcore: registered new interface driver dvb_usb_dib0700

9. You may also want to check for similar success with the Infrared receiver:

dmesg | grep DVB[ 12.972000] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in cold state, will try to load a firmware[ 13.780000] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm state.[ 13.780000] DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)[ 13.892000] DVB: registering frontend 0 (DiBcom 3000MC/P)...[ 14.392000] DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)[ 14.400000] DVB: registering frontend 1 (DiBcom 3000MC/P)...[ 14.960000] input: IR-receiver inside an USB DVB receiver as /class/input/input4[ 14.960000] dvb-usb: Hauppauge Nova-T 500 Dual DVB-T successfully initialized and connected.

Testing the Hauppauge WinTV Nova-T 500

1. MPLAYER and Xine can be used by MythTV to play media content that is not

natively supported. For example, they can play MP4 files whereas MythTV currentlycannot. They can also be used to test that the Tuner card is operating correctly beforewe install MythTV. Follow the instructions below to install these packages:

sudo apt-get upgradesudo apt-get install dvb-utils dvbstreamsudo apt-get install xine-ui mplayer

2. We now need to tune the TV Tuner card in to pick up the local DVB channels. I livenear to London in the UK so I use the Crystal Palace UK DVB-T configuration file because it is able to detect my DVB channels well. You may need to use a different

settings file from that directory depending on which country/town you are nearest to.

cd ~/mkdir /root/.tzap

cd /usr/share/doc/dvb-utils/examples/scan/dvb-tscan uk-CrystalPalace > /root/.tzap/channels.conf

0x6000 0x6a00: pmt_pid 0x03f0 Channel 4 TV -- Film4 (running)0x6000 0x6780: pmt_pid 0x0402 BBC -- BBC World Sv. (running)0x6000 0x6a80: pmt_pid 0x03f2 Camelot Group plc -- Lottery Xtra (running)Network Name 'Crystal Palace'dumping lists (104 services)Done.




Page 14 of 46

3. From one terminal I now tune in to BBC One and leave it running:

tzap –r "BBC ONE"

4. From another terminal I launch the DVB stream into one of the media players I

installed (either MPLAYER or XINE). Both commands should be run from the localmachine, they will fail if you run the commands remotely from an SSH terminal.

dvbstream -o -ps 600 601 -qam 16 -cr 3_4 | mplayer –

or

dvbstream -o -ps 600 601 -qam 16 -cr 3_4 | gxine stdin://mpeg2

You should now see the channel you selected above playing on your Linux machine.

Installing MythTV

Installing MythTV Server

1.

To install MythTV follow the instructions below. If you get errors when trying toinstall MythTV via Aptitude then you may need to go back to the section entitledUpdating Aptitude and enable all the repositories that are listed and then try again.

sudo apt-get updatesudo apt-get install mythtv mythtv-themes

2. During the installation you will be prompted to provide a root password for MySQL(this is the database server that gets installed for MythTV to store its information into).Pick a memorable password and write it down because you will need it later on.

3. You will also be asked if you would like to enable Remote Connections from other MythTV front-ends on your network. Since you may want other machines on your network to connect to your server for the purposes of watching television or films Iwould advise you select yes for this option. Your broadband router should by defaultnot allow computers that are external (such as those on the Internet) to connect in.

4. After the installation completes, make sure that the Myth Backend is running:

/etc/init.d/mythtv-backend start

Configuring MythTV Backend

1. This process was documented during the installation of MythTV 0.20. However, the process for MythTV 0.21 is almost identical and you should be able to use the guide below equally well for MythTV 0.21 (although some options are on different screens).

2. From the desktop menu, select System / Administration / MythTV Backend Setup

3. You will be asked the following question; “You must be a member of the mythtv group before starting any mythtv applications. Would you like to automatically beadded to the group?” Select OK, you will be encouraged to log out and back in again.

Installing MythTV Plugins

1. Install the MythTV plugins package by following the instructions below. As part of the installation you will be prompted whether or not you wish to password-protectMythWeb. I would recommend that you do (we will also look at SSL security later).

sudo apt-get -y install mythplugins

2. Restart your web server for the changes to be picked up in MythWeb:

/etc/init.d/apache2 restart

3. Test the MythWeb installation by navigating to http://192.168.2.100/mythweb/

4. Place an empty index.html file into /var/www/ to prevent browsing your web-root:

touch /var/www/index.html

5. Configure MythVideo by following starting MythTV Frontend, navigating to Setup /Video Settings / General Settings and then entering the information shown below:

General Settings (1/2)

Directory that holds videos: /var/lib/mythtv/videos

Directory that holds posters: /var/lib/mythtv/videos-posters

Default View: Gallery

General Settings (2/2)

Show Unknown File Types: [unchecked ]

Video Browser browses files: [unchecked ]

Video Gallery browses files: [unchecked ]

Video List browses files: [unchecked ]

Copying over your Media Files to MythTV

1. You will no doubt have media files that you have encoded into MPG or MP4 formaton your computer that you now want to view on your TV using MythTV. To be ableto access this content via MythTV you will need to follow the steps outlined below:

2.

Firstly copy all the video media files into the directory /var/lib/mythtv/videos

cp *.mpg /var/lib/mythtv/videoschown mythtv:mythtv /var/lib/mythtv/videos/*

3. Now follow these steps to load in the metadata and images for the videos from IMDB

MythTV Main Menu

Select Videos, then select Video Manager

Video Manager

The list of all the media you copied over should now appear in

the list. Click I (for Information) and the Action menu will appear

Action Menu

Select Search IMDB from the Action menu. You can

alternatively enter the IMDB number manually if you know it.

Action Menu

MythTV will search the IMDB and bring back a list of all the

possible matches for the video file. You should then select the

correct one from that list. If no match is found then you can

always input the IMDB number manually if you know it.

Next time you enter the Video Gallery the poster and the details

for your movie files will be available for browsing.

Configure the Hauppauge Remote Control

1. To use the Hauppauge Remote Control that came with your tuner card you shouldfollow the steps below. Make sure that the remote receiver is plugged into the back of your computer and that the remote control is within line-of-sight of the receiver.

cat /proc/bus/input/devices

2. Look for the entry for your remote control (it should look like that shown below):

I: Bus=0003 Vendor=2040 Product=9950 Version=0100N: Name="IR-receiver inside an USB DVB receiver"P: Phys=usb-0000:01:08.2-1/ir0S: Sysfs=/class/input/input4H: Handlers=kbd event4B: EV=3B: KEY=14afc336 284284d 0 0 0 4 80058000 2190 40000801 9e96c0 0 900200 ffd

3. Make a note of the Handlers line and the event (the input device the remote control isusing). My IR receiver uses event4. This can be tested by running the followingcommand and pressing some buttons on the remote control. Please note not to hit thePower button on your remote because by default this will shut your machine down.

sudo evtest /dev/input/event4

4. Install the required components for integrating MythTV with your remote control:

apt-get updateapt-get install lirc

5. Copy over the following files from Appendix A of this document

/etc/lirc/hardware.conf /etc/lirc/lircd.conf

/home/mythtv/.lircrc

6. Some of the settings from .lircrc require certain keyboard shortcuts to exist inMythTV (for example ALT+H to jump to the Home Screen). You will need to

configure these in the Edit Keys section of the MythTV Settings menu.

7. Start the LIRC daemon and test the remote control keys:

sudo /etc/init.d/lirc startirw

8. Link the .lircrc file to the MythTV lircrc file and then start the Front-end to test:

ln -s /home/mythtv/.lircrc /home/mythtv/.mythtv/lircrc

Adding the Finishing Touches

Configuring the Desktop User Interface

1. The purpose of this section is to configure the MythTV server so that it allows you to play back video and TV without being interrupted by system sounds, screen savers

and other alerts commonplace on a computer that could spoil your viewing pleasure.These steps should all be completed whilst logged in as the mythtv user.

2. From the Desktop menu select System / Preferences / Power Management . On the ACPower Tab, slide the two sliders to the far right (the word ever appears as below).

This will prevent the display turning off when you a watching a long TV program andwill prevent the computer sleeping and becoming unresponsive during TV playback.

3. On the General tab select Shutdown as the action for when the user presses the Power button and Do othing as the action for when the user presses the Suspend button.

4. From the Desktop menu select System / Preferences / Removable Media. Uncheck allthe auto-mount and auto-play features so that inserting a DVD or a removable hard-

disk into your MythTV server doesn’t cause the TV player to be disrupted.




Page 29 of 46

5. From the Desktop menu select System / Preferences / Sound Preferences. Ensure that o Sound is selected against each of the system sounds that are listed on the screen.

Configuring Automatic Login and Start up of MythTV Front-end

1. It is nice to have the MythTV Frontend run automatically when you power on your MythTV server. In order to do this you will need to automate the log in of the mythtv

user. Follow the steps below to have the mythtv user automatically log in at boot:

vi /etc/gdm/gdm.conf-custom

{add under the daemon section}

[daemon]AutomaticLoginEnable=trueAutomaticLogin=mythtv

2. Now, to ensure MythTV Front-end runs when the mythtv user logs in:

touch /home/mythtv/.gnomercchmod 755 /home/mythtv/.gnomercvi /home/mythtv/.gnomerc

sleep 5 && mythfrontend > /tmp/mythfrontend.log 2>&1 &

Adding Support for DVD Playback and Restricted Formats

1. Some of your media may be in formats that are not natively supported under Linux.Follow these steps to include support for CSS encrypted DVDs and Windows codecs.First add the Medibuntu sources to Aptitude by issuing the following commands:

wget http://www.medibuntu.org/sources.list.d/gutsy.list -O /etc/apt/sources.list.d/medibuntu.list

wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add - && sudo apt-get update

2. Now install the components for DVD playback and the common Windows codecs

sudo apt-get -y install ubuntu-restricted-extrassudo apt-get –y install libdvdcss2sudo apt-get –y install w32codecs

Secure Apache2 with SSL

1. You may wish to secure some of the URLs on your web server with SSL encryption

so that information passed over the internet between your client PC and the MythTVserver (such as passwords) cannot be read or intercepted. This would be particularly

useful to help secure MythWeb. Follow the steps below to install and configure SSL.

sudo apt-get install opensslsudo apt-get install ssl-cert

2. Now create an SSL certificate for your website:

make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/ssl/private/certname.pem

Country Name: GBState or Province: LondonLocality: LondonOrganisation: DavOSOrganisational Unit Name: DavOSHost Name: www.davos.co.ukEmail Address: [email protected]

a2enmod sslModule ssl installed; run /etc/init.d/apache2 force-reload to enable.

3. Edit the ports configuration file so Apache listens for SSL connections on port 443:

vi /etc/apache2/ports.conf

Listen 80<IfModule mod_ssl.c>

Listen 443</IfModule>




Page 31 of 46

4. Copy the default configuration file so that it can be edited for the SSL configuration:

cp /etc/apache2/sites-available/default /etc/apache2/sites-available/sslln -s /etc/apache2/sites-available/ssl /etc/apache2/sites-enabled/sslsudo a2ensite ssl

5. We now add rewrites to force certain URLs (on port 80) to use an SSL connection:

vi /etc/apache2/sites-available/default

NameVirtualHost *:80<VirtualHost *:80>

ServerAdmin webmaster@localhost

DocumentRoot /var/www/

RewriteEngine OnRewriteCond %{HTTPS} off

#RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}RewriteRule (/mythweb/*) https://%{HTTP_HOST}%{REQUEST_URI}

Order deny,allowDeny from allAllow from 127.0.0.0/255.0.0.0 ::1/128

</Directory>

</VirtualHost>




Page 32 of 46

6. We now edit the SSL configuration to specify the certificate we will be using:

vi /etc/apache2/sites-available/ssl

NameVirtualHost *:443

<VirtualHost *:443>ServerAdmin webmaster@localhost

DocumentRoot /var/www/

SSLEngine OnSSLCertificateFile /etc/ssl/private/certname.pem

</Directory>

</VirtualHost>

7. Finally, reload Apache. You should be able to test the above configuration by

navigating to MythWeb on your MythTV server. A certificate will be displayed andyou will be redirected to use an HTTPS (SSL) connection instead of standard HTTP.

sudo /etc/init.d/apache2 force-reload

Installing FFMPEG with full MP4 support

1. The version of FFMPEG that comes as standard from the Ubuntu repositories has been heavily crippled. In order to install FFMPEG with support for MP4 follow thesteps below. First use Aptitude to download and install the required libraries:

su

apt-get -y build-dep ffmpegapt-get -y install liblame-dev libfaad2-dev libfaac-dev libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev checkinstall build-essential subversion

2. Use subversion to check out the latest source code for FFMPEG

cdsvn checkout -r 8998 svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

3. Configure and make FFMPEG

cd ffmpeg

./configure --enable-gpl --enable-pp --enable-libvorbis --enable-libogg --enable-liba52 --enable-dc1394 --enable-libgsm --disable-debug --enable-libmp3lame --enable-libfaad --enable-libfaac --enable-xvid --enable-pthreads --enable-x264

make

4. Run checkinstall to configure and install FFMPEG. Make sure your settings arecomparable to the settings below. Please note that you will want to use your own

email address for the maintainer (this package will not be delivered externally).

checkinstall

Should I create a default set of package docs? [y]:This package will be built according to these values:

0 - Maintainer: [ [email protected] ]1 - Summary: [ Package created with checkinstall 1.6.1 ]2 - Name: [ ffmpeg ]3 - Version: [ 3:0.svn20080308 ]4 - Release: [ 1 ]5 - License: [ GPL ]6 - Group: [ checkinstall ]

7 - Architecture: [ i386 ]8 - Source location: [ ffmpeg ]9 - Alternate source location: [ ]10 - Requires: [ ]

ENTER to continue

Installing Handbrake

1. Handbrake is a superb DVD ripper for Linux. To install it go to the Handbrakewebsite at http://handbrake.fr/ and download the Linux version to your user homedirectory. Now follow the steps below from a Terminal to install it:

tar -xzvf HandBrake-0.9.2_i386.tar.gzsudo cp HandBrakeCLI /usr/local/bin

2. Handbrake requires a relatively long command line to rip DVDs. I have thereforewritten a script to wrap Handbrake and make it easier to rip directly into MythVideo.The script, called /usr/local/bin/ripdvd, can be found in Appendix A of this guide.

Installing NFS

1. NFS will allow you to share the contents of your MythTV video and video-postersdirectories on your local network so that other MythTV Front-ends can access anduse the same media content across the network. To install NFS on the server followthe steps below. When you are asked whether to bind loopback you should say no.

sudo apt-get install nfs-kernel-server nfs-common portmapsudo dpkg-reconfigure portmapsudo /etc/init.d/portmap restart

2. To share the MythTV directory on the network you should do the following:

vi /etc/exports

{ADD}

/var/lib/mythtv *(ro,sync,no_subtree_check)

/etc/init.d/nfs-kernel-server restart

3. Now on the client machines (such as on your MythTV front-ends):

apt-get install portmap nfs-commonsudo vi /etc/fstab

{ADD}

192.168.2.100:/var/lib/mythtv /var/lib/mythtv nfs rw,hard,intr 0 0




Page 35 of 46

Installing PHPMyAdmin

1. PHPMyAdmin will allow you to configure and manage MythTV directly from thedatabase. To install PHPMyAdmin you will need to visit the PHPMyAdmin websiteat http://www.phpmyadmin.net/ and download the latest all-languages.zip file.

2. Place all-languages.zip into /var/www/ and run the following from a terminal:

cd /var/wwwunzip phpMyAdmin-*-all-languages.zipmv phpMyAdmin-*-all-languages phpmyadminrm phpMyAdmin-*-all-languages.zip

3. Change the PHPMyAdmin configuration file by adding the blowfish secret:

cd /var/www/phpmyadminmv config.sample.inc.php config.inc.php

vi config.inc.php

{CHANGE }

$cfg['blowfish_secret'] = 'hello';

4. You should now be able to log into PHPMyAdmin by entering your MythTV

database username and password into the site http://192.168.2.100/phpmyadmin

Scripts for Encoding Recordings to iPhone/iTouch format

1. When recordings have finished I use a script to encode those recordings into MP4 andFLV format so that they can be played on my iPhone and on a networked computer.

If you also want this functionality then copy my mythencode.sh script from AppendixA of this document to /usr/local/bin/ and then set the permissions on it as follows:

chmod 755 /usr/local/bin/mythencode.sh

2. Create the directories required for the encoded media files:

mkdir –p /var/www/tv/flvmkdir –p /var/www/tv/iconsmkdir –p /var/www/tv/mp4

chown mythtv:mythtv /var/www/tv/flvchown mythtv:mythtv /var/www/tv/iconschown mythtv:mythtv /var/www/tv/mp4

chmod 775 /var/www/tv/flvchmod 775 /var/www/tv/iconschmod 775 /var/www/tv/mp4

3. Create soft links from the shared directory to the MP4 directory:

mkdir -p /shared/mediachown mythtv:mythtv /shared/mediachmod 775 /shared/media

ln –s /var/www/tv/mp4 /shared/media/tv

4. We now need to add mythencode.sh as a User Job in MythTV so that it runs bydefault after a recording finishes. The script will then encode that recording into MP4and FLV format and publish the files onto the shared drive and onto the web server.When adding a User Job to MythTV you can use any of the following variables:

Parameter Description

%DIR% The directory component of the recording's filename

%FILE% The filename component of the recording's filename

%TITLE% The title of the recording (e.g., name of the series)%SUBTITLE% The subtitle of the recording (e.g., name of the episode)

%DESCRIPTION% The description text for the recording (from guide data)

%HOSTNAME% The backend making the recording

%CATEGORY% The category of the recording (from guide data)

%RECGROUP% The recording group

%CHANID% The MythTV channel ID making the recording

%STARTTIME% The recording start time (YYYYMMDDhhmmss)

%ENDTIME% The recording end time (YYYYMMDDhhmmss)

%PROGSTART% The recording's start time (from guide data)

%PROGEND% The recording's end time (from guide data)




Page 37 of 46

5. Run MythTV-Backend and select General, then on the Job Queue (Host-specific)settings screen check the box that says Allow User #1 Jobs. Click ext two times andthen enter the following in the User Job #1 Description and Command boxes:

/usr/local/bin/mythencode.sh "%FILE%" "%TITLE%" "%STARTTIME%"

6. Go to MythWeb (http://192.168.2.100/mythweb/), then go to the Setting page andclick MythTV Settings Table. Now enter the following information into the table:

Setting Value

AutoCommercialFlag 0

AutoExpireDefault 1

AutoExpireExtraSpace 1

AutoExpireLiveTVMaxAge 1

AutoRunUserJob1 1

AutoTranscode 0

7. Now save your settings and close MythWeb.

8. The standard MythTV recordings will auto-delete themselves when disk space isrequired, however the MP4 and FLV encoded versions will not. Therefore you willneed to use a script to delete old media to ensure that these files don’t fill up your filesystem. The mythclean script in Appendix A is written by me for this purpose. Copy

it over to /usr/local/bin/ and then use the cron to schedule it to run every 24 hours.

chmod 755 /usr/local/bin/mythclean

APPENDIX A – Configuration Files

This appendix contains configuration and script files for key components referencedthroughout the main MythTV Installation guide. The filename for each configurationfile is shown above each listing. To install these configuration files and scripts simply

copy the contents of the listing into the filename specified.

/usr/local/bin/mythencode.sh

This script is called by MythTV User Job 1 after it completes recording a television program. It will encode the recording into MP4 and FLV format, and place those

resulting media files onto the network file server and onto the web server.
