How to install MythTV

From QNAPedia

Jump to: navigation, search

QNAP NAS devices have a relatively fast processor in them. Here is a guide to get MythTV running on them. This guide is no where near complete, it doesn't cover problems that may arise, and assumes a fair amount of linux knowledge and experience. But give it a go even if you don't know much, and I'll try to help (see the section on Problems?).

Contents

Initial Setup

Web setup

Following steps performed through the Web interface http://<qnap ip>:1010/

  • Install IPKG from the web interface
    • Application Servers->QPKG Plugins->GetQPKG->Optware IPKG
    • Installation Tab->Browse to .qpkg file->INSTALL
    • QPKG INSTALLED Tab->Optware->Enable
  • Allow console login
    • Network Services->Telnet/SSH
    • Allow SSH connection->APPLY

Console setup

So now you have a terminal with ipkg installed and enabled, log into your qnap device and let's get to work!

ssh admin@<qnap ip>

you should get

[~]

First let's go somewhere with lots of spare room (might also be MD0_DATA for raided drives)

[~] mkdir /share/HDA_DATA/labatory
[~] cd /share/HDA_DATA/labatory

you should see

[/share/HDA_DATA/labatory]

Second let's get some essential utilities for our experimentation

[/share/HDA_DATA/labatory] ipkg install nano gcc make automake ncurses ncursesw wget ncurses-dev
[/share/HDA_DATA/labatory] ipkg install patch coreutils pkgconfig
[/share/HDA_DATA/labatory] ipkg install perl perl-libxml perl-dbi
[/share/HDA_DATA/labatory] ipkg install findutils sed grep gawk


(this step will take a while as these packages are downloaded and installed to your qnap device)

Ok, so now were are ready to start delving into the compilation of the modules required for MythTV. Depending on your setup you will either want to build and install modules for USB tuners or skip that step because you are using a network tuner and start compiling Qt... (Note even if you are using a network tuner you will still need to download and untar the kernel source, it is required for dvb headers)



Using Kernel modules tuners

Get linux and qnap sources. NOTE: YOU DO NOT NEED THIS STEP IF YOU HAVE A HOMERUN HD DEVICE.

wget ftp://ftp.jp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.33.2.tar.gz
wget http://resources.qnap.com/Storage/tsd/QNAP_GPL_3.3.3-20100928.tar.gz
(or ftp://ftp.qnap.com/gpl/QNAP_GPL_3.4.x_20110218.tar.gz)

untar these sources

tar xzvf QNAP_GPL_3.3.3-20100928.tar.gz
tar xzvf linux-2.6.33.2.tar.gz

browse to the folder that corresponds to your QNAP

cd GPL_TS/kernel_cfg
ls

I own a TS-219P

cd TS-219

Copy the kernel config file that corrosponds to your kernel version (type uname -r to find out which one you have) to the kernel source files

ls
uname -r

should return

2.6.33.2
cp ./linux-2.6.33.2-arm.cfg ../../../linux-2.6.33.2/.config

go to that folder

cd ../../../linux-2.6.33.2/
nano .config

enable i2c and media (make sure the following exists in the .config file, do a search)

CONFIG_I2C=m 
CONFIG_MEDIA_SUPPORT=m

setup the ncurses libraries

ln -s /opt/lib/libncurses.so /lib/libncurses.so
ln -s /opt/lib/libncurses.so.5 /lib/libncurses.so.5
ln -s /opt/lib/libncurses.so.5.7 /lib/libncurses.so.5.7
ln -s /opt/lib/libncursesw.so /lib/libncursesw.so
ln -s /opt/lib/libncursesw.so.5 /lib/libncursesw.so.5
ln -s /opt/lib/libncursesw.so.7 /lib/libncursesw.so.7
make oldconfig

Make sure you answer as follows

I2C support (I2C) [M/n/y/?] m
Multimedia support (MEDIA_SUPPORT) [M/n/y/?] m
DVB for Linux (DVB_CORE) [N/m/?] (NEW) m
Support for various USB DVB devices (DVB_USB) [N/m/?] (NEW) m
Customise the frontend modules to build (DVB_FE_CUSTOMISE) [N/y/?] (NEW) y

Start the compilation of the kernel modules

make modules

This will take some time … so go for a swim, read to your kids, or develop a unified field theory.

After it has completed you should be left with loadable dvb usb tuner and support modules.

I2C Problems?

To get the i2c-core.ko module to work, you will need to follow this post http://forum.qnap.com/viewtopic.php?p=194182#p202235

Once all the modules are compiled, I ran

make install

which makes it easier to load the correct modules in the right order using modprobe as per the link to a post below

I have a Hauppage Win Nova-t usb stick, I follow the folloing post to get the correct modules to load and load the firmware. http://forum.qnap.com/viewtopic.php?p=194182#p208102

Compiling Qt

NOTE: Whereas those compiling Qt on firmware 3.5.1 have had success, those on firmware 3.5.2 have not.

Initial Setup

Qt expects certain libraries to be present, happily we have ipkg to fulfill that requirement

ipkg install fontconfig libdb libjpeg libpng libtiff libstdc++ x11 xauth xproto xrender

(this need works to determine exactly what is required for correct compilation of Qt)


Compiling

Get Qt sources

wget http://download.qt-project.org/archive/qt/4.7/qt-everywhere-opensource-src-4.7.4.tar.gz

untar these sources

tar zxf qt-everywhere-opensource-src-4.7.4.tar.gz

let's get started!

cd qt-everywhere-opensource-src-4.7.4

setup X11 paths

export QMAKE_LIBDIR_X11=/opt/lib/
export QMAKE_INCDIR_X11=/opt/include/X11

configure and build Qt

./configure --opensource -confirm-license -release -prefix /opt/Qt-4.7.3 -I /usr/local/mysql/include/mysql -L /usr/local/mysql/lib/mysql -reduce-relocations -qt-libtiff -qt-libpng -qt-libmng -sql-mysql-plugin -no-multimedia -nomake tools -nomake examples -nomake demos -nomake docs -webkit
make
make install

This will take a long time, I am doing this on a 1.2GHz ARM platform and it has taken at least 12 hours. Be patient.

Compiling MythTV

Initial Setup

MythTV also expects certain libraries to be present, again we rely on ipkg (thanks ipkg devs)

ipkg install ffmpeg lame xextensions xvid yasm


Compiling

Get MythTV sources.  While the instructions are for 0.24.1 (released May 15, 2011), it's the same process for 0.24.3 (released Apr 12, 2012).  The 0.24.1 patches also work for 0.24.3.

wget ftp://ftp.osuosl.org/pub/mythtv/old_releases/mythtv-0.24.1.tar.bz2
or
wget ftp://ftp.osuosl.org/pub/mythtv/old_releases/mythtv-0.24.3.tar.bz2

unbz these sources

tar xfj mythtv-0.24.1.tar.bz2

let's get started!

cd mythtv-0.24.1

first we need to patch configure and other files to get it to work on this platform (How to install MythTV#Appendix). there are quite a number of changes to source of MythTV, I don't think the authors ever intended it to be used in this manner ... oh well too bad ^_^  create the patches in the appendix and patch MythTV:

nano mythtv_qnap.patch

PASTE text from five patches in appendix and save file:
  1) configure.patch
  2) mythcdrom-linux.cpp.patch
  3) mythdisplay.cpp.patch
  4) mythxdisplay.cpp.patch
  5) cpsvndir.patch

patch -p2 -i mythtv_qnap.patch

configure and build MythTV (disable frontend not functional?)

./configure --disable-frontend --prefix=/opt --qmake=/opt/Qt-4.7.3/bin/qmake --cpu='i686'

if you have not installed your kernel headers (additional dvb-path for non installed kernel dvb headers, requires confirmation for people building with a network tuner)

./configure --prefix=/opt --qmake=/opt/Qt-4.7.3/bin/qmake [--dvb-path=/share/HDA_DATA/labatory/linux-2.6.33.2/include/]

start building

make
make install

And now it is on to setup ...

MythTV Backend Setup

Mostly steps from http://www.mythtv.org/wiki/User_Manual:Initial_Installation

Database

So currently you should have an "in thoery" working version of MythTV. However it is not setup correctly. Try the following

[/share] # mythbackend 
2011-09-15 22:07:31.138 mythbackend version:  [v0.24.1] www.mythtv.org
2011-09-15 22:07:31.140 Using runtime prefix = /opt
2011-09-15 22:07:31.141 Using configuration directory = /root/.mythtv
2011-09-15 22:07:31.145 Unable to read configuration file mysql.txt
2011-09-15 22:07:31.146 Empty LocalHostName.
2011-09-15 22:07:31.146 Using localhost value of NAS
2011-09-15 22:07:31.244 New DB connection, total: 1
2011-09-15 22:07:31.300 Unable to connect to database!
2011-09-15 22:07:31.300 Driver error was [1/1045]:
QMYSQL: Unable to connect
Database error was:
Access denied for user 'mythtv'@'localhost' (using password: YES)

So now you need to setup the database

/usr/local/mysql/bin/mysql -u root < database/mc.sql -p

Done, let's try again

[/share/HDA_DATA/hackery/mythtv-0.24.1] # mythbackend

If you get the following response:

2011-11-11 09:11:36.186 Empty LocalHostName.
2011-11-11 09:11:36.186 Using localhost value of Caerbannog
QSqlDatabase: QMYSQL3 driver not loaded

2011-11-11 09:11:36.192 MSqlDatabase::OpenDatabase(), db object is not valid!

then the mysql plugin didn't get built. Run the following:

cd qt-everywhere-opensource-src-4.7.4/src/plugins/sqldrivers/mysql/
make; make install

then try again

[/share/HDA_DATA/hackery/mythtv-0.24.1] # mythbackend

Success! Now we have to run mythtv-setup this is a little more indepth an involves setting up a "forwarding X session".

Missing timezone support 

Starting with firmware 3.7.1, mythtv (I tested with 0.26pre) complains about missing timezone support. In case you hit this problem, install timezones into mysql:

> mysql_tzinfo_to_sql /usr/share/zoneinfo | /usr/local/mysql/bin/mysql -u root -p mysql

This installs timezone info from the NAS (which is located in /usr/share/timezone) to mysql. Unfortunately, the information for UTC is missing on the NAS, leaving mythtv still unstartable.

As I could not figure out a clean way how to generate the UTC timezone information, I simply executed the mysql script for the UTC timezone on my linux box and pasted the insert statements into the mysql on the NAS:

> mysql -u root -p mysql
INSERT INTO time_zone (Use_leap_seconds) VALUES ('N');
SET @time_zone_id= LAST_INSERT_ID();
INSERT INTO time_zone_name (Name, Time_zone_id) VALUES ('UTC', @time_zone_id);
INSERT INTO time_zone_transition_type (Time_zone_id, Transition_type_id, Offset, Is_DST, Abbreviation) VALUES
(@time_zone_id, 0, 0, 0, 'UTC');
ALTER TABLE time_zone_transition ORDER BY Time_zone_id, Transition_time;
ALTER TABLE time_zone_transition_type ORDER BY Time_zone_id, Transition_type_id;

I am not sure if this is the recommended way but it seems to work, as mythtv starts thereafter.

X11 Forwarding

Server configuration

The following steps are not necessary when connecting with a Windows client using Xming as specified below.

So now you have a to forward the X session over ssh (compile and run http://en.literateprograms.org/Hello_World_%28C,_Xlib%29 to test the forwarding works).  

Edit sshd_config file in /etc/ssh enable X11forwarding twice in the file (by uncommenting and changing the value to yes)  

X11Forwarding yes

restart the ssh daemon through the Qnap web admin interface to enable these changes.   

In my case the forwarding did still not work. The reason was that sshd was compiled with a xauth path that does not exist on the Qnap NAS. In order to fix this, extract the xauth location from the sshd executable and cerate a symlink so that sshd finds xauth under the expected path (this has to be done on the NAS):

> strings /usr/sbin/sshd | grep xauth
/usr/X11R6/bin/xauth
xauthlocation
maxauthtries
> ln -s /opt/bin/xauth /usr/X11R6/bin/xauth

Client configuration

I'm on windows vista, I installed Xming (an X server for Windows): http://sourceforge.net/projects/xming/  

Edit the X0.hosts file (C:/program files/Xming) and add the ip address of your mythbackend (QNAP) machine

With XLaunch: open an X window, leave all options as-is with the display set at 0

log in to your Qnap box on your windows client with Putty run the following command prior to running mythtv-setup:

export DISPLAY=192.168.X.X:0.0

where the ip address above is the client computer. This may only work if you are on the same local subnet as the NAS (on your home LAN).  Some may need to enabling X11 forwarding to your windows client in your putty session. (Connection > SSH > X11 > enable X11 forwarding + X display location = localhost:0)

On linux simply add -X (the X has to be uppercase!) as argument to the ssh call:

ssh -X <ip.of.your.nas>

mythtv-setup

  • run mythtv-setup, run a scan, populate the channels, I had some issues with fonts and themes here, it was really annoying

Fonts A lot of people are having problems with themes/fonts when running mythtv-setup, where empty squares are displayed instead of letters. If you have this behavior, one solution may be to run the following commands to copy the themes folder and font folder from the source to the install location. It worked for at least one person, so others should report results.

cp -r mythtv-0.24.1/themes/ /opt/share/mythtv/
cp -r mythtv-0.24.1/themes/fonts /opt/share/mythtv/fonts

MythWeb

MythWeb allows control of the MythTV backend from a web interface, including setting up recordings, displaying status

  1. If QNAPfirmware < 3.7.1, install PHP5.3 per steps 1 - 4 here for 219P+; PHP5.3 is included with 3.7.1
  2. copy mythweb source files from zip into Public share
  3. ssh into NAS
  4. cp -r /share/Public/MYTHWEBROOTDIR /share/Web/mythweb
  5. chown -R httpdusr /share/Web/mythweb
  6. chmod -R 755 /share/Web/mythweb
  7. nano /etc/config/apache/apache.conf
    +add "Include /etc/config/apache/extra/mythweb.conf" at very bottom
  8. cp /share/Web/mythweb/mythweb.conf.apache /etc/config/apache/extra/mythweb.conf
  9. nano /etc/config/apache/extra/mythweb.conf
    +edit paths to match /share/Web/mythweb/data and /share/Web/mythweb

Setup authentication (following is DIGEST authentication):

  1. /mnt/ext/opt/apache/bin/htdigest -c  /etc/config/apache/extra/mythweb.password "MythTV" INSERTUSERNAMEHERE
  2. nano /etc/config/apache/extra/mythweb.conf
    +uncomment the directives in the authentication section (7 total in my version)
    +change AuthUserFile to /etc/config/apache/extra/mythweb.password
    +add the following line before the authentication section:
    LoadModule auth_digest_module modules/mod_auth_digest.so

In case you can not get DIGEST authentication to work, use BASIC authentication. This does not provide as much security as DIGEST, but is better than nothing:

  1. /mnt/ext/opt/apache/bin/htpasswd -c /etc/config/apache/extra/mythweb.password INSERTUSERNAMEHERE
  2. nano /etc/config/apache/extra/mythweb.conf
    +uncomment the directives in the authentication section (7 total in my version)
    +change AuthType from Digest to Basic
    +change AuthUserFile to /etc/config/apache/extra/mythweb.password

In case your installing mythweb > 0.24.3 the following step is also needed:

  1. nano /etc/config/apache/extra/mythweb.conf
    +uncomment "setenv include_path" variable and set to MYTHTV_INSTALLPATH/share/mythtv/bindings/php"
    this is needed for mythweb>0.24.3 due to this update. If not done, you'll see the following error in the browser loading mythweb: "Fatal error: Class 'MythBase' not found in /share/MD0_DATA/Web/mythweb/classes/Translate.php on line 16" error.

That's it. you now only need to restart Apache:

  1. /etc/init.d/Qthttpd.sh restart
  2. go to http://NAS-ip-address/mythweb


Mythweb complains about the timezone array being incorrect.  A solution is to run the following commands when mythtv is started (of course, use the appropriate timezone!):

  1. mv /etc/localtime /etc/localtime_old
  2. ln -s /usr/share/zoneinfo/US/Eastern /etc/localtime

These commands are included in the QPKG startup script in the appendix.  You can also setup logging for the backend through mythweb:

  1. Navigate to mythweb->Settings->MythTV and find the LogEnabled flag.
  2. Set LogEnabled to 1 and click save at the bottom.
  3. Find "Backend Logs" at the top.

The Backend Logs page may at first display the following error:

Warning at /share/MD0_DATA/Web/mythweb/modules/backend_log/tmpl/default/backend_log.php, line 30:<br>!!NoTrans: array_keys() expects parameter 1 to be array, null given!!

Warning at /share/MD0_DATA/Web/mythweb/modules/backend_log/tmpl/default/backend_log.php, line 30:<br>!!NoTrans: Invalid argument supplied for foreach()!!

but once there are some log entries, that error will disappear and the entries will show.

MythTV Backend boot scripts

autorun.sh method

Normally would you loose all these nice settings on reboot. You can do this by using the bash script below and following the steps outlined in Running Your Own Application at Startup.

eg

[/share/HDA_DATA/.qpkg/autorun] # cat autorun.sh 
#!/bin/sh

# additional lib path
echo "/opt/lib" >> /etc/ld.so.conf
ldconfig

# create dvb devices
/share/HDA_DATA/.qpkg/autorun/dvb-devices

# set correct locale (remove incorrect)
#localedef -f UTF-8 -i en_AU en_AU.utf8
#localedef --delete-from-archive en_US.utf8

# load kernel modules
insmod /lib/modules/others/i2c-core.ko
insmod /lib/modules/others/dvb-core.ko
insmod /lib/modules/others/dvb-usb.ko
insmod /lib/modules/others/dvb-usb-af903x.ko

# start mythbackend
#mythbackend &

QPKG script method

This method makes mythbackend appear as a QPKG to the QNAP Package Management System and QPKT admin webpage, which allows one to disable/enable and start/stop/restart MythTV. If the "MythTV QPKG" is enabled, the QNAP will start it on boot. Steps to setup are below:

  • SSH/Telnet into the QNAP
  • copy #MythTV.sh in appendix to /share/MD0_DATA/.qpkg/MythTV/MythTV.sh or other location
  • Open /etc/config/qpkg.conf using vi/nano and insert the #addition_to_qpkg.conf snipit in Appendix to the QPKG config file (edit "shell" to match the location of the script above)
  • Login to the QNAP Admin Web UI & go to QPKG to use your Script

Performance

  • User: ybot Testing was done on a QNAP 219P, with a MacBook Pro frontend with gigabit ethernet (Netgear GS105) connection. The frontend is showing 720p DVB streams from the QNAP as it is recording the same HD stream to the harddrive. I haven't seen any issues related to either the HD stream being written to the harddrive or the stream from the harddrive to the network port, both these processes seem robust. In regards to process stats I see the following data:-
    • mythbackend (33M memory footprint)
      • Idle - average 0.0-0.1 CPU usage
      • Recording - average 0.0-2.0 percent CPU
      • Recording + streaming - average 3-5 percent CPU with no >10 percent.
    • mysqld - average 0-1 percent CPU, with occasional 5-10 percent spikes
  • If you are running a network tuner you will need to make sure your network can handle the traffic generated by this (tuner device -> QNAP -> Frontend)
  • Please put in your experiences here!

Further Work

I am looking at several different ways of speeding up compilation and reducing end user pain


Tips (README!)

  • Use the screen utility (ipkg install screen) it helps with long compile sessions.
  • Compilation is pretty CPU intensive so you will see a degradation of performance, just don't use it while it is compiling :)
  • Be smart, this stuff takes time to compile and setup, do a couple of things at once
    • Download all the required source in the background
    • Qt isn't dependent on the kernel modules, get both of them compiling at once


Problems?
