General

What is Jajuk?

Jajuk is an advanced Jukebox used to manage large or scattered music collections for advanced users

What is Jajuk license ?

Jajuk is free software published under the GPL license

Which formats are supported?

Please find the full list

How to install Jajuk?

Please consult Jajuk Installation Guides

Do you plan to read DVD and pictures etc... with Jajuk and make it a media center ?

It is very unlikely. We want to make a jukebox with as many features as we can for advanced users. We want to manage Music and make it right.

Can Jajuk play only the audio of a video? (Jajuk > 1.6)

In the Configuration, Preferences view , use "-novideo" in Mplayers argument .

Can Jajuk play / encode Audio CDs ?

No, Jajuk doesn't currently support Audio CDs read nor encode. Jajuk goal is primary to play existing audio files like MP3, not to create them. To encode/rip your CDs, we suggest using dedicated programs like the excellent CDex .(Note that Jajuk supports Data CDs with audio files like mp3s)

Technical

How to select sound device in case of multiple sound cards ?

How much resources does Jajuk use?

(Windows) How to map statically a letter to a drive ?

What's the Java process I sometimes see, in addition to Jajuk, using a noticeable amount of CPU cycles?

This is the ThumbBuilder process that builds thumbnail images for catalog and suggestion views. Let to finish, it will run only once.

Troubleshooting

All Operating systems

Jajuk takes large CPU resources

When discovering new albums, Jajuk creates thumbnails in 6 sizes (from 50x50 pixels to 300x300 pixels) in the .jajuk directory. This is done using a dedicated java process that can last for several minutes for large new collections. It is done only once, please wait until the thumbs are created. Jajuk usually takes near 0% of CPU.

I experience sound skips

I experience Out Of Memory issues

By default, Jajuk can use from 35MB to 512MB of physical memory. That should be large enough for most users. If you have a really huge collection and experience out-of-memory problems, increase the -Xmx value in the Jajuk launch script (open a support ticket if you need help)

What can I do if my collection looks *really* corrupted ?

Check out the device page of the jajuk manual . Note that this case has never been reported so far as Jajuk provides an efficient built-in recovery system.

Jajuk cannot read files with non-ASCII characters

(Characters different from [a to z] like 'é' 'ç', Asian ideograms...)This is a filename encoding problem due to a wrong file system mounting option, a quick fix is to rename your filenames to utf-8 see https://trac.jajuk.info/ticket/955 for details.

Windows Only

Crash at startup

In some cases (with few graphical cards), Jajuk starts, the splash screen is shown and then, the entire application crashes. Workaround : disable tray by deleting file <jajuk installation path>\lib\windows\x86\tray.dllNote that this problem should be fixed in Jajuk 1.6 (due to 2008/05/11)

A "pop" (think "standard windows 'pop' sound") is heard between tracks

It's a sound emitted by the system when opening the systray balloons. We can't disable this sound as it is managed by Windows itself. You can:

Firefox is set as default browser, I use JRE 1.6 Sun and I regularly get this message: "java.net.MalformedURLException: unknown protocol: socket"

1) go to Control Panel -> Java2) click the Network Settings button3) Select Direct Connection, and click ok a couple of times to exit

Cannot run Jajuk on Vista 64 bits (cannot execute 32 bits dll)

(Thanks elefkof SF user)You need to install both a 32-bit and 64-bits JRE. It will allow you to have a 64-bit and 32-bit versions alongside each other. It will use the 32-bit JRE for 32 bit apps and 64 bit JRE for 64 bit apps. See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4802695

Access is denied under Vista

Conflict between Web Start install and .Exe installer

If you launch Jajuk in Web start mode (Try it live), icons and startup menus are created. After installing Jajuk from the download jajuk-<version>-win32.exe file, launching Jajuk from the new created icon still executes the Web start version.

Linux Only

Some Japanese fonts are not displayed correctly (squares) in some part of the screen

See: https://trac.jajuk.info/ticket/799 or https://help.ubuntu.com/community/Japanese_in_Java

After setting a cross-fade, the next track cannot start

This can be caused by a wrong mplayer configuration that uses OSS or ALSA and not the sound engine that prevents from playing several songs together. Edit ~/.mplayer/conf and add a line like 'ao=esd' under Gnome or 'ao=arts' under KDE.

I get totally or partially blank screens when using XGL

If under JRE 1.5, it may help to set this environment variable: AWT_TOOLKIT=MToolkit. Otherwise (not tested), try using xnest (install it if required). That should start Jajuk using a generic X configuration using 'Xnest :1 & DISPLAY=":1" jajuk'

My frame position and size is not kept between sessions or the frame is displayed at wrong position

Jajuk blank frame and other various graphical issues using Beryl WM

This is caused by an incompatibility between Sun JRE and Beryl. If under JRE 1.6, you can use :

Cross fade doesn't work under Linux (two mplayer processes cannot be launched concurrently)

Mplayer is not available and I get an "audio line occupied" message

Try stopping all audio apps, check mute mode is not enable, check nothing users /dev/dsp (fuser /dev/dsp as root). If you still have the issue, it is probably an Alsa deamon problem, please read <span class="icon">http://forum.ubuntu-fr.org/viewtopic.php?id=12019</span> this doc.

Right click on tray makes the popup only flash

This is a jdic issue we can't fix. Just keep mouse pressed one second or two.

Problems displaying non-latin characters

The problem may be with with xorg's locales (see this thread ). For russian for ie, the cure is:

sudo ln -s /usr/share/X11/locale/en_US.UTF-8 /usr/share/X11/locale/ru_RU.UTF-8

I experience sound skips

Make sure to use mplayer if under Linux or Mac OSX
