Installing MythArchive Dependencies
MythBurn is one of several solutions to the problem of getting video out of your MythTV box on to DVD-Video discs so you can play them in your DVD player.
The user interface for Mythburn integrates into Mythweb and allows you to select recordings to store on the DVD, graphics and sound for the DVD menu etc.
Mythburn can either create an ISO-image of the DVD, that you can burn on a different PC or it can burn the DVD directly, if you have a DVD-writer in the backend
If a recording is too large to fit on a DVD, Mythburn will automatically shrink (recompress) the recording, so that the resulting size is less than 4.7 GB.
MythWeb depends upon a number of other software packages that have to be installed.
According to http://www.knoppmythwiki.org/index.php?page=MythTVBurn_Scripts_HowTo these are:
- mjpegtools 1.6.2
- dvdauthor 0.6.10
- imagemagick 6.0.6
- transcode 0.6.14
- ProjectX 0.90.3.01
- a Java JRE or JDK
- mythBurn from CVS
In addition you need growisofs from dvd+rw-tools to write the ISO-file to the DVD.
Even though http://www.knoppmythwiki.org/index.php?page=MythTVBurn_Scripts_HowTo states that "dvdauthor<0.6.12 does NOT work with imagemagick>6.0.7.x", I have had success running dvdauthor 0.6.11-1.1 together with ImageMagick 126.96.36.199-2.
RPM installation of some of the packages
If your system is rpm based, you can check the current installed versions with the rpm command:
- rpm -q mjpegtools
- rpm -q dvdauthor
- rpm -q imagemagick or rpm -q ImageMagick
- rpm -q transcode
- rpm -q jre
- rpm -q jdk
- rpm -q dvd+rw-tools
- rpm -q cvs
Note that on some rpm-sites ImageMagick is called imagemagick (KnoppMyth) and on other it is called ImageMagick (freshrpms)
If your system is rpm based you can install some of the packages with apt-get or yum:
- apt-get update
- apt-get install mjpegtools
- apt-get install dvdauthor
- apt-get install ImageMagick (or imagemagick)
- apt-get install transcode
- apt-get install dvd+rw-tools
- apt-get install cvs
Maybe your apt-get or yum has not been set up to correct repositories to get these packages. So you might have to update your sources.list or yum configuration.
On Fedora Core 3 I have installed mjpegtools from atrpms.net, dvdauthor and transcode from apt.sw.be, ImageMagick and dvd+rw-tools from freshrpms.net.
To install java, download either a JDK or JRE from http://java.sun.com/j2se/1.5.0/download.jsp. The JRE contains the runtime that ProjectX needs to run, while the JDK contains both the compiler that you need for compiling ProjectX and the runtime. So if you want to compile ProjectX on a different PC, then you only need the JRE.
The installation is very straight forward. If you have downloaded a file like jre-1_5_0_<version>-linux-i586-rpm.bin, then you need the following commands:
- chmod a+x jre-1_5_0_<version>-linux-i586-rpm.bin
This will not set up the path to the Java bin folder or set any Java environment variable. It would be an advantage to do this, as scripts would be independent from the actual location and version of the Java jre, but I do not know how to set this up properly...
ProjectX needs to be version 0.90.3.01 or later, which is not available as precompiled package, so you need to compile it. However it can be compiled on any computer even on a Windows PC !
Download the source from http://sourceforge.net/project/showfiles.php?group_id=115063 (e.g the file ProjectX_Source_eng_0.90.4.00.zip), uncompress it (e.g to the folder /usr/share/projectx) and run the build.sh file. As I have not set up the path and environment correctly, that did not work for me, so I ran build.bat from a Windows PC with the JDK installed and then ProjectX was compiled.
Then create a script for starting projectx. That might be placed in /usr/bin or some other folder, where your path points to. Mine is placed in /usr/bin and called projectx and has the following content:
#!/bin/sh /usr/java/jre1.5.0_06/bin/java -jar /usr/share/projectx/projectX.jar $@
If you have set up the java environment, then you can omit the path before java. Otherwise adjust it to where your java is installed.
Make the script executable (chmod a+x /usr/bin/projectx)
Also make sure that ProjectX is placed in an executable folder (chmod a+x /usr/share/projectx)
Test if ProjectX can be started from a command prompt. On a X terminal ProjectX should start, while on a ssh prompt, it should show some messages and end with the following error message:
Checking Commons-Net library access... Loading AC3 frames... Stopped! Can't start GUI, Classes not available...
If it does that, then ProjectX is probably properly installed. Note that Mythburn will run ProjectX as the user "apache" (it runs within MythWeb) and all access rights should be set to allow "apache" to run ProjectX.
The current version of mythburn does work with MythTV 0.19. Before you proceed you might make a backup of your MythWeb scripts as MythBurn will modify them.
The MythBurn script has to be downloaded from CVS. You can do that with the commands:
- mkdir /usr/share/mythburn
- chmod a+x /usr/share/mythburn
- cd /usr/share/mythburn
- cvs -d:pserver:firstname.lastname@example.org:/cvsroot/mythburn checkout mythburn
Check if any error messages are issued. I received one, because I already had MythStreamTV installed, so the init.php was modified compared to what the MythBurn installation script expected. The error message however indicated which lines I had to modify and that was easily done.
MythWeb is now modified and will have menu options for starting MythBurn.
If you later want to update to latest version of MythBurn, you can do that with:
- cd /usr/share/mythburn
- cvs update
Even though the Mythburn script asks where the application tcrequant is placed, some versions have a hardcoded path to /usr/local/bin/tcrequant. If your tcrequant is placed somewhere else, you could make a symbolic link from /usr/local/bin/tcrequant. On my system I had to create the following:
- ln -s /usr/bin/tcrequant /usr/local/bin/tcrequant
If your system already has tcrequant in the correct place or if you have a Mythburn script without this bug, then you do not need the symbolic link.
Without tcrequant Mythburn will not be able of shrinking the size of a recording.
MythWeb main menu with additional menu entries for starting MythBurn:
First MythBurn page, where the recordings to be included on the DVD can be selected:
Second MythBurn page, where the DVD menu is defined. Notice the last option "Show debug information?" which can be used for debugging. Selecting this will make the following page show the command line used to start the DVD creation script. If you copy that command line and start it in a terminal, you will better be able to follow the process and see any error messages issued.
Third and last MythBurn page, where the last log messages can be shown:
