problems with Zekr 1.0.0 on Ubuntu Lucid

[Benjamin Geer]

As-Salamu Alaykum,

I've just installed Zekr 1.0.0 from the Debian package on Ubuntu Lucid, and I'm having a few problems.

First, when I press "play" on the audio player, the audio (an offline MP3 recitation) starts playing.  If I stop the audio by pressing "stop", the audio stops, but Zekr then hangs.  My zekr.log is attached.  I'm using OpenJDK because it is required by libjlayer-java, which seems to be necessary for playing MP3 recitations, according to this thread:

http://groups.google.com/group/zekr/browse_thread/thread/464f984c7b6eba35/a68d6519ea53b5ea?show_docid=a68d6519ea53b5ea

Second, if I try to adjust the audio volume using the volume control on the player, I get this error:

net.sf.zekr.engine.audio.PlayerException: javazoom.jlgui.basicplayer.BasicPlayerException: Gain control not supported

at net.sf.zekr.engine.audio.DefaultPlayerController.setGain(DefaultPlayerController.java:187)

Third, the "Go" buttons do not cause the main window to scroll to the selected aya; the display remains at the beginning of the selected sura.

Wa Alaikumassalaam,

First and second issues relate to OpenJDK. This is a known issue with open JDK and you should use Sun JRE instead to fix it:

http://zekr.org/wiki/Installation#Install_A_Compatible_Java_JRE

Third bug relates to your browser and issue in current swt package available. Can you reproduce it with our basic .tar.gz package?

Those instructions say to install the package "sun-java6-jre", but that package is no longer available in Ubuntu Lucid by default.  Users need to perform extra steps to install it:

http://www.ubuntugeek.com/how-install-sun-java-runtime-environment-jre-in-ubuntu-10-04-lucid-lynx.html

I followed those instructions to install the Sun JRE, and uninstalled OpenJDK, and now I get this error when I press "play" on the audio player:

No, none of these problems occur with the .tar.gz package.

Salaam,

1. You don't have libjlayer-java installed:

$ sudo apt-get install libjlayer-java

2. We should wait until Ahmed or Mohammad update swt package on Zekr PPA.

Mohsen

If I do this, it also installs openjdk-6-jre-headless and openjdk-6-jre-lib.  Then when I press "play" in the audio player, I get this error:

This is what I was trying to say before: Zekr won't play any audio if OpenJDK is installed, but libjlayer-java requires OpenJDK.

Salaam

And here's the funny part: on my machine with Debian Squeeze 64bit, I
have both javas: openJDK and Sun JRE, and with OpenJDK audio usually
works (have to restart Zekr from time to time though; and get the same
message as the one above from time to time too), but with Sun JRE it
does not work at all (I click on "Play", nothing happens, no error
messages, nothing).

Beside all that, Sun's Java is getting removed from repos (Ubuntu
Lucid already removed it), so I wonder if depending on it is a wise
move. Isn't there any other way to implement audio feature avoiding
these, I'd say traditionally recurring, java problems? I personally
don't mind fiddling with system to get it work, but what about people
who really have no idea what to do to make it work (even with
instructions present)?

Yes, then users may optionally use WebKitGTK+ as the browser and some issues they currently face with PPA package but not wih tar.gz package will resolve.

Benjamin, does this help when using OpenJDK (editing /etc/java-6-openjdk/sound.properties)?

http://tuxguitar.herac.com.ar/forum/5/1778/tuxguitar-no-sound/

We should find a way to have Zekr audio work with OpenJDK, as it seems this is the only Java available to Ubuntu users.

Mohsen

[Mohsen Saboorian]

How about playing other formats such as Speex or OGG? If you can play Speex for example, then it means that only mp3decoder library has bug and we can provide more offline recitation formats to bypass this issue. But if you see the same problem with Speex or OGG, then basicplayer is buggy.

Unfortunately at Java side you don't have many options for playing audio files such as MP3s.

Our previous method of playing audio files was delegating this to the browser. This has its own drawbacks as flash plugin is non-free and almost buggy for Linux users. If we choose HTML5 audio feature, it won't support MP3 on Linux and in addition to that, we need a complete re-code at Zekr side.

Mohsen

Done !

Salam,

what is to be done exactly to make it work?

I'd be happy to try, but what should I change in that file?

Now I'm puzzled: if you go with OGG instead of MP3, how will that
reflect on the issue? What is the best solution in the long run? HTML5–
OpenJDK–OGG?

Ben,

Could you install Ubuntu Restricted Extras:

$ sudo apt-get install ubuntu-restricted-extras

and tell us about the result. Seems that MP3 playing should work even with OpenJDK?

Sorry, I don't have an Ubuntu 10.04 box for now. As this is a common issue for Linux users, please help us fix this by checking different configurations.

Salaam,

As I mentioned earlier, if the issue relates to mp3 decoding java library, it can be fixed by using speex or ogg. we already support these formats in .tar.gz package. Our debian package may also play these formats if these are installed:

libvorbisspi-java

libjspeex-java

libjorbis-java

Meho, please make a change to one of your installed offline recitation descriptors  (.properties) files either in <zekr>/res/audio or ~/.zekr/audio. Change file type from .mp3 to .ogg (audio.offlineUrl, see this), and convert a few of your mp3s into ogg in the related folder. Then try to play it with Zekr. Tell us about the result.

Mohsen

I forgot to update zekr package in order to use SWT 3.6, I just fixed
that now on Zekr PPA.
